Risk factors for cardiac rupture after acute ST-segment elevation myocardial infarction during the percutaneous coronary intervention era: a retrospective case-control study

BackgroundIn percutaneous coronary intervention (PCI) era, more clinically valuable risk factors are still needed to determine the occurrence of cardiac rupture (CR). Therefore, we aimed to provide evidence for the early identification of CR in ST-segment elevation myocardial infarction (STEMI).MethodsA total of 22,016 consecutive patients with STEMI admitted to Cangzhou Central Hospital and Tianjin Chest Hospital from January 2013 to July 2021 were retrospectively included, among which 195 patients with CR were included as CR group. From the rest 21,820 STEMI patients without CR, 390 patients at a ratio of 1:2 were included as the control group. A total of 66 patients accepted PCI in the CR group, and 132 patients who accepted PCI in the control group at a ratio of 1:2 were included. The status of first medical contact, laboratory examinations, and PCI characteristics were recorded. Multivariate logistic regression analysis was used to investigate the risk factors related to CR.ResultsThere was a higher proportion of patients with myocardial infarction (MI) in the high lateral wall in the CR group (23.6% vs. 8.2%, P<0.001). The proportion of single lesions was lower in the CR group (24.2% vs. 45.5%, P=0.004). Female (OR =2.318, 95% CI: 1.431–3.754, P=0.001), age (OR =1.066, 95% CI: 1.041–1.093, P<0.001), smoking (OR =1.750, 95% CI: 1.086–2.820, P=0.022), total chest pain time (OR =1.017, 95% CI: 1.000–1.035, P=0.049), recurrent acute chest pain (OR =2.750, 95% CI: 1.535–4.927, P=0.001), acute myocardial infarction (AMI) in the high lateral wall indicated by ECG (OR =5.527, 95% CI: 2.798–10.918, P<0.001), acute heart failure (OR =3.585, 95% CI: 2.074–6.195, P<0.001), and NT-proBNP level (OR =1.000, 95% CI: 1.000–1.000, P=0.023) were risk factors for CR in all patients. In patients who accepted PCI, single lesion (OR =0.421, 95% CI: 0.204–0.867, P=0.019), preoperative thrombolysis in myocardial infarction (TIMI) grade (OR =0.358, 95% CI: 0.169–0.760, P=0.007), and postoperative TIMI grade (OR =0.222, 95% CI: 0.090–0.546, P=0.001) were risk factors for CR.ConclusionsNon-single lesions and preoperative and postoperative TIMI grades were risk factors for CR in patients who accepted PCI. In addition to previously reported indicators, we found that AMI in the high lateral wall maybe helpful in early and accurate identification and prevention of possible CR.     

Impact of COVID-19 on Cardiovascular Disease Presentation,Emergency Department Triage and Inpatient Cardiology Services in a Low- to Middle-Income Country – Perspective from a Tertiary Care Hospital of Pakistan

Aims:To identify the changes in cardiovascular disease presentation, emergency room triage and inpatient diagnostic and therapeutic pathways.Methods:We conducted a retrospective cohort study at the Aga Khan University Hospital, Karachi. We collected data for patients presenting to the emergency department with cardiovascular symptoms between March–July 2019 (pre-COVID period) and March–July 2020 (COVID period). The comparison was made to quantify the differences in demographics, clinical characteristics, admission, diagnostic and therapeutic procedures, and in-hospital mortality between the two periods.Results:Of 2976 patients presenting with cardiac complaints to the emergency department (ED), 2041(69%) patients presented during the pre-COVID period, and 935 (31%) patients presented during the COVID period. There was significant reduction in acute coronary syndrome (ACS) (8% [95% CI 4–11], p < 0.001) and heart failure (↓6% [95% CI 3–8], p < 0.001). A striking surge was noted in Type II Myocardial injury (↑18% [95% CI 20–15], p < 0.001) during the pandemic. There was reduction in cardiovascular admissions (coronary care unit p < 0.01, coronary step-down unit p = 0.03), cardiovascular imaging (p < 0.001), and procedures (percutaneous coronary intervention p = 0.04 and coronary angiography p = 0.02). No significant difference was noted in mortality (4.7% vs. 3.7%). The percentage of patients presenting from rural areas declined significantly during the COVID period (18% vs. 14%, p = 0.01). In the subgroup analysis of sex, we noticed a falling trend of intervention performed in females during the COVID period (8.2% male vs. 3.3 % female).Conclusions:This study shows a significant decline in patients presenting with Type I myocardial infarction (MI) and a decrease in cardiovascular imaging and procedures during the COVID period. There was a significant increase noted in Type II MI.     

Effectiveness and Acceptability of a Mobile Phone Text Messaging Intervention to Improve Blood Pressure Control (TEXT4BP) among Patients with Hypertension in Nepal: A Feasibility Randomised Controlled Trial

Background:Uncontrolled blood pressure (BP) is the leading cause of preventable deaths in low- and middle-income countries. mHealth interventions, such as mobile phone text messaging, are a promising tool to improve BP control, but research on feasibility and effectiveness in resource-limited settings remains limited.Objective:This feasibility study assessed the effectiveness and acceptability of a mobile phone text messaging intervention (TEXT4BP) to improve BP control and treatment adherence among patients with hypertension in Nepal.Methods:The TEXT4BP study was a two-arm, parallel-group, unblinded, randomised controlled pilot trial that included 200 participants (1:1) (mean age: 50.5 years, 44.5% women) with hypertension at a tertiary referral hospital in Kathmandu, Nepal. Patients in the intervention arm (n = 100) received text messages three times per week for three months. The control arm (n = 100) received standard care. The COM-B model informed contextual co-designed text messages. Primary outcomes were change in BP and medication adherence at three months. Secondary outcomes included BP control, medication adherence self-efficacy and knowledge of hypertension. A nested qualitative study assessed the acceptability of the intervention.Results:At three months, the intervention group had greater reductions in systolic and diastolic BP vs usual care [–7.09/–5.86 (p ≤ 0.003) vs –0.77/–1.35 (p ≥ 0.28) mmHg] [adjusted difference: systolic β = –6.50 (95% CI, –12.6; –0.33) and diastolic BP β = –4.60 (95% CI, –8.16; –1.04)], coupled with a greater proportion achieving target BP (70% vs 48%, p = 0.006). The intervention arm showed an improvement in compliance to antihypertensive therapy (p < 0.001), medication adherence (p < 0.001), medication adherence self-efficacy (p = 0.023) and knowledge on hypertension and its treatment (p = 0.013). Participants expressed a high rate of acceptability and desire to continue the TEXT4BP intervention.Conclusion:The TEXT4BP study provides promising evidence that text messaging intervention is feasible, acceptable, and effective to improve BP control in low-resource settings.Trial registration:anzctr.org.au Identifier ACTRN12619001213134.     

Association of marital status with cardiovascular outcome in patients with breast cancer

BackgroundThe influences of marital status on cardiovascular death risk in patients with breast cancer remained unclear. This study aimed to evaluate the associations of different marital status with cardiovascular death risk in patients with breast cancer.MethodsA total of 182,666 female breast cancer patients were enrolled in this study from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2014, and was divided into two groups: married (N=107,043) and unmarried (N=75,623). A 1:1 propensity score matching (PSM) was applied to reduce inter-group bias between the two groups. Competing-risks model was used to assess the associations between different marital status and cardiovascular death risk in patients with breast cancer.ResultsAfter PSM, marital status was an independent predictor for cardiovascular death in patients with breast cancer. Unmarried condition was associated with increased cardiovascular death risk than married condition among breast cancer patients [unadjusted model: hazard ratio (HR) =2.012, 95% confidence interval (CI): 1.835–2.208, P<0.001; Model 1: HR =1.958, 95% CI: 1.785–2.148, P<0.001; Model 2: HR =1.954, 95% CI: 1.781–2.144, P<0.001; Model 3: HR =1.920, 95% CI: 1.748–2.107, P<0.001]. With the exception of separated condition (adjusted HR =0.886, 95% CI: 0.474–1.658, P=0.705), further unmarried subgroups analysis showed that the other three unmarried status were associated with increased cardiovascular death risk as follows: single (adjusted HR =1.623, 95% CI: 1.421–1.853, P<0.001), divorced (adjusted HR =1.394, 95% CI: 1.209–1.608, P<0.001), and widowed (adjusted HR =2.460, 95% CI: 2.227–2.717, P<0.001). In particularly, widowed condition showed the highest cardiovascular death risk in all 4 unmarried subgroups.ConclusionsUnmarried condition (e.g., single, divorced and widowed) was associated with elevated cardiovascular death risk compared with their married counterparts in patients with breast cancer, suggesting that more attention and humanistic care should be paid to unmarried breast cancer patients (especially the widowed patients) in the management of female breast cancer patients.     

A Molécula de Lesão Renal-1 está Associada à Nefropatia Induzida por Contraste em Pacientes Idosos com IAMSSST

Background Contrast-induced nephropathy (CIN) is associated with an increased risk of major adverse cardiovascular events (MACE), and the association between CIN and oxidative mechanisms is well documented.Objective This study aimed to evaluate the relationship between serum levels of kidney injury molecule-1 (KIM-1) and CIN in elderly patients with non-ST-segment elevation myocardial infarction (NSTEMI).Methods This study included a total of 758 patients with NSTEMI, who underwent percutaneous coronary intervention (PCI); 15 developed CIN after PCI, and another 104 were the control group, matched for age > 65 years. Baseline to 48-to-72-hour laboratory values and clinical outcomes were recorded. Patients were followed during one year. P values of < 0.05 were considered significant.Results CIN was observed in 12.60% of the patients. Serum KIM-1 was significantly higher in the CIN group than in the non-CIN group (14.02 [9.53 – 19.90] vs. 5.41 [3.41 – 9.03], p < 0.001). The Mehran score was significantly higher in the CIN group than in the non-CIN group (14 [5 – 22] vs. 5 [2 – 7], p = 0.001). MACE were significantly higher in the CIN group than in the non-CIN group (7 [46.70%] vs. 12 [11.50%], p = 0.001). Multivariate logistic regression analysis showed that baseline KIM-1 level (OR = 1.652, 95% CI: 1.20 – 2.27, p = 0.002) and Mehran score (OR = 1.457, 95% CI: 1.01 – 2.08, p = 0.039) were independent predictors of CIN in elderly patients with NSTEMI.Conclusion Baseline serum KIM-1 concentration and Mehran score are independent predictors of CIN in elderly patients with NSTEMI. Additionally, all-cause mortality, cardiovascular death, myocardial reinfarction, stroke, and MACE were significantly higher in the CIN group at one-year follow-up.

Hospitalização por Infarto Agudo do Miocárdio: Um Registro de Base Populacional

Background:ST-segment elevation myocardial infarction (STEMI) is one of the main clinical manifestations of ischemic heart disease. Population-based data are relevant to better understand the current epidemiology of this condition.Objective:To describe the incidence, therapeutic management, hospital clinical outcomes and cardiovascular events in the first year of follow-up of individuals hospitalized for STEMI.Methods:Population-based prospective cohort study with consecutive registries of hospitalization for STEMI in a city in southern Brazil from 2011 to 2014. It included patients with STEMI who presented acute myocardial ischemia symptoms in the last 72 hours. A p-value < 0.05 was considered significant.Results:The annual incidence of STEMI hospitalizations was 108 cases per 100,000 inhabitants. Adjusted incidence was higher among older individuals (relative risk 64.9; 95% CI 26.9–156.9; p for linear trend < 0.001) and among men (relative risk 2.8; 95% CI 2.3–3.3; p < 0.001). There were 530 hospitalizations in the period under evaluation and the reperfusion rate reached 80.9%. Hospital mortality and the one-year follow-up cardiovascular event rate were, respectively, 8.9% and 6.1%. The oldest patients had higher hospital mortality (relative risk 3.72; 95% CI 1.57–8.82; p for linear trend = 0.002) and more one-year follow-up cardiovascular events (hazard ratio 2.35; 95% CI 1.12–4.95; p = 0.03).Conclusion:This study shows that both the therapeutic approach and hospital mortality are similar to the ones found in developed countries. However, the hospitalization rate was higher in these countries.     

Is Lone Hypertension a Risk Factor for More Severe COVID-19 Outcomes?

Background:Based on current evidence, it is not clear whether lone hypertension increases the risk for severe illness from COVID-19, or if increased risk is mainly associated with age, obesity and diabetes. The objective of the study was to evaluate whether lone hypertension is associated with increase mortality or a more severe course of COVID-19, and if treatment and control of hypertension mitigates this risk.Methods:This is a prospective multi-center observational cohort study with 30-day outcomes of 9,531 consecutive SARS-CoV-2 PCR-positive patients ≥ 18 years old (41.9 ± 9.7 years, 49.2% male), Uzbekistan, June 1-September 30, 2020. Patients were subclassified according to JNC8 criteria into six blood pressure stages. Univariable and multiple logistic regression was conducted to examine how variables predict outcomes.Results:The 30-days all-cause mortality was 1.18% (n = 112) in the whole cohort. After adjusting for age, sex, history of myocardial infarction (MI), type-2 diabetes, and obesity, none of six JNC8 groups showed any significant difference in all-cause mortality. However, age was associated with an increased risk of 30-days all-cause mortality (OR = 1.09, 95%CI [1.07–1.12], p < 0.001), obesity (OR = 7.18, 95% CI [4.18–12.44], p < 0.001), diabetes (OR 4.18, 95% CI [2.58–6.76], p < 0.001), and history of MI (OR = 2.68, 95% CI [1.67–4.31], p < 0.001). In the sensitivity test, being ≥ 65 years old increased mortality 10.56-fold (95% CI [5.89–18.92], p < 0.001). Hospital admission was 12.4% (n = 1,183), ICU admission 1.38% (n = 132). The odds of hospitalization increased having stage-2 untreated hypertension (OR = 4.51, 95%CI [3.21–6.32], p < 0.001), stage-1 untreated hypertension (OR = 1.97, 95%CI [1.52–2.56], p < 0.001), and elevated blood pressure (OR = 1.82, 95% CI [1.42–2.34], p < 0.001). Neither stage-1 nor stage-2 treated hypertension patients were at statistically significant increased risk for hospitalization after adjusting for confounders. Presenting with stage-2 untreated hypertension increased the odds of ICU admission (OR = 3.05, 95 %CI [1.57–5.93], p = 0.001).Conclusions:Lone hypertension did not increase COVID-19 mortality or in treated patients risk of hospitalization.     

Reabilitação Cardíaca Baseada em Exercícios Fortemente Relacionada com Redução do Volume Plaquetário Médio

BackgroundMean platelet volume (MPV), which is a simple measure of platelet activation, has recently become an interesting topic in cardiovascular research. Exercise-based cardiac rehabilitation (CR) is a comprehensive intervention that decreases mortality-morbidity in patients with coronary artery disease (CAD). Studies on the effects of exercise on platelet activation have yielded conflicting results.ObjectiveThe purpose of this study was to determine the effect of an exercise-based CR programs on MPV in patients with stable CAD.MethodsThe sample was composed of 300 consecutive stable CAD patients. The patients were divided into two groups: CR group (n = 97) and non-CR group (n = 203). Blood analysis was performed. Point-Biserial correlation measures were performed to show correlation between MPV change and CR. A p value of <0.05 was considered statistically significant.ResultsThe decrease in MPV was greater in the CR group than in the non-CR group [(-1.10(-1.40-(-0.90)) vs. (-0.10 (-2.00-0.00)); p< 0.001]. ΔMPV had a positive correlation with Δ neutrophil (r = 0.326, p < 0.001), ΔTG (r = 0.439, p < 0.001), ΔLDL-c (r = 0.478, p < 0.001), ΔWBC (r = 0.412, p < 0.001), and ΔCRP (r = 0.572, p < 0.001). A significant correlation was found between ΔMPV% and CR (r=0.750, p<0.001).ConclusionsWe were able to show that exercise-based CR has a strong relationship with MPV reduction in patients with CAD. We consider that decreased platelet activation with exercise-based CR might play an important role in reducing thrombotic risk in patients with stable CAD.

Characteristics and Clinical Outcomes of 116,539 Patients Hospitalized with COVID-19—Poland,March–December 2020

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Coronavirus Disease 2019 (COVID-19). This study aimed to characterize patients hospitalized with COVID-19 in Poland between March and December 2020, as well as to identify factors associated with COVID 19–related risk of in-hospital death. This retrospective analysis was based on data from the hospital discharge reports on COVID-19 patients hospitalized in Poland between March and December 2020. A total of 116,539 discharge reports on patients hospitalized with COVID-19 were analyzed. Among patients with COVID-19, 21,490 (18.4%) died during hospitalization. Patients over 60 years of age (OR = 7.74; 95%CI: 7.37–8.12; p < 0.001), men (OR = 1.42; 95%CI: 1.38–1.47; p < 0.001) as well as those with cardiovascular diseases (OR = 1.51; 95%CI: 1.46–1.56; p < 0.001) or disease of the genitourinary system (OR = 1.39; 95%CI: 1.31–1.47; p < 0.001) had much higher odds of COVID 19–related risk of in-hospital death. The presence of at least one comorbidity more than doubled the COVID 19–related risk of in-hospital death (OR = 2.23; 95%CI: 2.14–2.32; p < 0.01). The following predictors of admission to ICU were found in multivariable analysis: age over 60 years (OR: 2.03; 95%CI: 1.90–2.16), male sex (OR: 1.79; 95%CI: 1.69–1.89), presence of at least one cardiovascular disease (OR: 1.26; 95%CI: 1.19–1.34), presence of at least one endocrine, nutritional and metabolic disease (OR: 1.17; 95%CI: 1.07–1.28).     

Cardiovascular Risk Is Elevated in Lean Subjects with Nonalcoholic Fatty Liver Disease

Background/AimsNonalcoholic fatty liver disease (NAFLD) and obesity are independently associated with an increased risk for atherosclerotic cardiovascular disease (ASCVD), the leading cause of mortality in patients with NAFLD. Many NAFLD patients are lean, but their ASCVD risk compared to obese subjects with NAFLD is unclear.MethodsData from the 2008 to 2011 Korea National Health and Nutrition Examination Surveys database were analyzed (n=4,786). NAFLD was defined as a comprehensive NAFLD score ≥40 or a liver fat score ≥–0.640. ASCVD risk was evaluated using the American College of Cardiology/American Heart Association guidelines.ResultsThe frequency of subjects without NAFLD, with obese NAFLD, and with lean NAFLD was 62.4% (n=2,987), 26.6% (n=1,274), and 11.0% (n=525), respectively. Subjects with lean NAFLD had a significantly higher ASCVD score and prevalence of a high ASCVD risk (mean 15.6±14.0, 51.6%) than those with obese NAFLD and without NAFLD (mean 11.2±11.4, 39.8%; mean 7.9±10.9, 25.5%; all p<0.001). Subjects with lean NAFLD and significant liver fibrosis showed a significantly higher odds ratio for a high risk for ASCVD than those with obese NAFLD with or without significant liver fibrosis (odds ratio, 2.60 vs 1.93; p=0.023).ConclusionsSubjects with lean NAFLD had a significantly higher ASCVD score and prevalence of high risk for ASCVD than those with obese NAFLD. Similarly, lean subjects with significant liver fibrosis had a higher probability of ASCVD than obese subjects in the subpopulation with NAFLD.     

Sensibilidade e Especificidade de Pontos de Corte para Frequência Cardíaca em Repouso de 6.794 Adolescentes Brasileiros: Um Estudo Transversal

Background Resting heart rate (RHR) may be a useful screening tool for cardiovascular risk. However, RHR cutoff points, an interesting clinical approach, have never been described in young populations.Objective To establish RHR cutoff points in Brazilian adolescents and to analyze whether cutoff points are associated with cardiovascular risk factors.Methods The sample was composed of 6,794 adolescents (10 to 19 years old). Blood pressure and RHR were assessed by oscillometric device. Body mass index and waist circumference were also assessed. Receiver operating characteristic curve was adopted to analyze the sensitivity and specificity, and associations of high RHR with cardiovascular risk factors were analyzed by binary logistic regression. A p value < 0.05 was considered statistically significant for all the analyses.Results Mean RHR values were higher among participants ages 10 to 14 years than 15 to 19 years, for boys (p < 0.001) and girls (< 0.001). The proposed RHR cutoff points for cardiovascular risk factors detection were significant for boys ages 10 to 14 (> 92 bpm) and 15 to 19 years (> 82 bpm), as well as for girls ages 15 to 19 years (> 82 bpm) (p < 0.05 for all), whereas no cutoff point was identified for girls ages 10 to 14 years (p > 0.05). Proposed RHR cutoff points were associated with abdominal obesity, overweight, and high blood pressure in boys in girls. RHR cutoff points were associated with the cluster of cardiovascular risk factors in adolescents ages 15 to 19 years.Conclusion The proposed RHR cutoff points were associated with cardiovascular risk factors in adolescents.     

Alterações Longitudinais nos Níveis de Atividade Física e Parâmetros de Risco Cardiovascular em Pacientes com Doença Arterial Periférica Sintomática

Background:Previous cross-sectional studies have demonstrated that physical activity is associated with lower cardiovascular risk in patients with peripheral artery disease (PAD). However, it is not possible to establish causality, and longitudinal design studies are required.Objective:To analyze the changes in cardiovascular risk parameters and physical activity levels after a 2-year follow-up in patients with symptomatic PAD.Methods:This study started in 2015. In the first phase, 268 patients were included. In the second phase, after 2 years (median = 26 months), 72 patients were re-evaluated. Cardiovascular risk parameters, such as blood pressure, cardiac autonomic modulation, and arterial stiffness, and physical activity levels were measured at baseline and after 2 years of follow-up. Association among delta changes (values from follow-up – baseline) in physical activity and cardiovascular parameters were analyzed by multiple linear regression. The significance level was set at p < 0.05.Results:Patients reduced their total physical activity levels compared to baseline (baseline = 2257.6 ± 774.5 versus follow-up = 2041 ± 676.2 min/week, p = 0.001). After follow-up, ankle-brachial index (0.62 ± 0.20 versus 0.54 ± 0.20, p = 0.003), and standard deviation of all RR intervals (43.4 ± 27.0 versus 25.1 ± 13.4 ms, p < 0.001) were lower, whereas carotid-femoral pulse wave velocity was higher (9.0 ± 3.0 versus 10.7 ± 3.4 m/s, p = 0.002) compared to baseline values. We did not observe any association among delta values of physical activity levels and cardiovascular risk parameters.Conclusion:Patients with PAD had reduced physical activity levels and impaired cardiovascular risk parameters during 2-year follow-up.     

Prevalence and determinants of hypertension and associated cardiovascular risk factors: data from a population-based,cross-sectional survey in Saint Louis,Senegal

Background

The incidence of cardiovascular disease is growing worldwide and this is of major public health concern. In sub-Saharan Africa, there is a lack of epidemiological data on the prevalence and distribution of risk factors of cardiovascular disease. This study aimed at assessing the prevalence of hypertension and other cardiovascular risk factors among an urban Senegalese population.

Methods

Using an adaptation of the WHO STEPwise approach to chronic disease risk-factor surveillance, we conducted a population-based, cross-sectional survey from 3 to 30 May 2010 on 1 424 participants aged over 15 years. Socio-demographic and behavioural risk factors were collected in step 1. Physical anthropometric measurements and blood pressure were documented in step 2. Blood tests (cholesterol, fasting blood glucose, and creatinine levels) were carried out in step 3.

Results

The prevalence of hypertension was 46% (95% CI: 43.4–48%), with a higher prevalence in females (47.9%) than males (41.7%) (p = 0.015), and 50% of these hypertensive were previously undiagnosed. Mean age was 53.6 years (SD: 15.8). In known cases of hypertension, the average length of its evolution was 6 years 9 months (range 1 month to 60 years). Hypertension was significantly associated with age (p = 0.001), socio-professional category (p = 0.003), dyslipidaemia (p < 0.001), obesity (p < 0.001), physical inactivity (p < 0.001), diabetes (p < 0.001) and stroke (p < 0.001).

Conclusion

We found a high prevalence of hypertension and other cardiovascular risk factors in this population. There is need of a specific programme for the management and prevention of cardiovascular disease in this population.     

Long-term radiation therapy-related risk of second primary malignancies in patients with lung cancer

BackgroundWith the improvement of cancer therapy, a second primary malignancy (SPM) occurs more commonly among cancer survivors. At present, it remains unclear whether the radiation therapy for the initial lung cancer will increase the risk of developing a SPM. This study aims to investigate the long-term risk of a SPM attributable to the radiation therapy in patients with the initial lung cancer.MethodsPatients initially diagnosed with lung cancer between January 1975 and November 2011 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. SPM was defined as the occurrence of a second cancer at least five years after the diagnosis of the initial lung cancer. Age- and propensity score matching (PSM)-adjusted competing risk analyses were performed to compare the risk of SPM.ResultsOf 47,911 patients, 9,162 (19.1%) underwent radiotherapy for the initial lung cancer. The PSM-adjusted competing risk analyses showed that radiation therapy was associated with a lower overall risk of SPM (HR: 0.89, 95% CI: 0.84–0.94, P<0.001). Specifically, the risk of second primary melanoma (HR: 0.49, 95% CI: 0.29–0.81, P=0.006), second primary female breast cancer (HR: 0.65, 95% CI: 0.50–0.85, P=0.001), second primary prostate cancer (HR: 0.69, 95% CI: 0.58–0.84, P<0.001) and second primary thyroid cancer (HR: 0.23, 95% CI: 0.07–0.77, P=0.017) was found to decrease, while the risk for second primary esophageal cancer dramatically increased (HR: 1.76, 95% CI: 1.26–2.45, P<0.001).ConclusionsIn patients who received radiotherapy for the initial lung cancer, the risk decreased for second primary melanoma as well as for second primary cancers of female breast, prostate and thyroid gland but increased for second primary cancer of esophagus. On the whole, radiation therapy for initial lung cancer may not increase the overall risk of SPM.     

Escore Albumina-Bilirrubina para Predizer Desfechos em Pacientes com Cardiomiopatia Dilatada Idiopática

Background:Liver dysfunction is a postulated variable for poor prognosis in dilated cardiomyopathy (DCM).Objective:This study aimed to investigate the prognostic value of the albumin-bilirubin (ALBI) score, a relatively new model for evaluating liver function, in patients with idiopathic DCM.Methods:A total of 1025 patients with idiopathic DCM were retrospectively included and divided into three groups based on ALBI scores: grade 1 (≤ −2.60, n = 113), grade 2 (−2.60 to −1.39, n = 835), and grade 3 (> −1.39, n = 77). The association of ALBI score with in-hospital major adverse clinical events (MACEs) and long-term mortality was analyzed. P-value less than 0.05 was considered statistically significant.Results:The in-hospital MACEs rate was significantly higher in the grade 3 patients (2.7% versus 7.1% versus 24.7%, p < 0.001). Multivariate analysis showed that ALBI score was an independent predictor for in-hospital MACEs (adjusted odds ratio = 2.80, 95%CI: 1.63 – 4.80, p < 0.001). After a median 27-month follow-up, 146 (14.2%) patients died. The Kaplan–Meier curve indicated that the cumulative rate of long-term survival was significantly lower in patients with higher ALBI grade (log-rank = 45.50, p < 0.001). ALBI score was independently associated with long-term mortality (adjusted hazard ratio = 2.84, 95%CI: 1.95 – 4.13, p < 0.001).Conclusion:ALBI score as a simple risk model could be considered a risk-stratifying tool for patients with idiopathic DCM.     

Association between Birth Weight and Cardiovascular Risk Factors in Adolescents

Background

Birth weight (BW) is a medium- and long-term risk determinant of cardiovascular risk factors.

Objective

To assess the association between BW and cardiovascular risk factors in adolescents of the city of Salvador, Bahia state.

Methods

Cross-sectional study with comparison of BW groups. Sample comprising 250 adolescents classified according to the BMI as follows: high-normal (≥ 50th percentile and < 85th percentile); overweight (≥ 85th percentile and < 95th percentile); and obesity (≥ 95th percentile). The risk variables compared were as follows: waist circumference (WC); arterial blood pressure; lipid profile; glycemia; serum insulin; HOMA-IR; and metabolic syndrome. The BW was informed by parents and classified as follows: low (BW ≤ 2,500g); normal (BW > 2,500g and < 4,000g); and high (BW ≥ 4,000g).

Results

One hundred and fifty-three (61.2%) girls, age 13.74 ± 2.03 years, normal BW 80.8%, low BW 8.0%, and high BW 11.2%. The high BW group as compared with the normal BW group showed a higher frequency of obesity (42.9%, p=0.005), elevated SBP and DBP (42.9%, p=0.000 and 35.7%, p=0.007, respectively), and metabolic syndrome (46.4%, p=0.002). High BW adolescents as compared with normal BW adolescents had a prevalence ratio for high SBP 3.3 (95% CI: 1.7-6.4) and obesity 2.6 (95% CI: 1.3-5.2). The WC of high BW adolescents was 83.3 ± 10.1 (p=0.038). The lipid profile showed no statistically significant differences.

Conclusion

Our findings suggest that obesity, elevated SBP and DBP, and metabolic syndrome during adolescence might be associated with high BW.     

Factors Associated with Incarceration in Older Adults Experiencing Homelessness: Results from the HOPE HOME Study

BackgroundIn the US, the median age of adults experiencing homelessness and incarceration is increasing. Little is known about risk factors for incarceration among older adults experiencing homelessness. To develop targeted interventions, there is a need to understand their risk factors for incarceration.ObjectiveTo examine the prevalence and risk factors associated with incarceration in a cohort of older adults experiencing homelessness.DesignProspective, longitudinal cohort study with interviews every 6 months for a median of 5.8 years.ParticipantsWe recruited adults ≥50 years old and homeless at baseline (n=433) via population-based sampling.Main MeasuresOur dependent variable was incident incarceration, defined as one night in jail or prison per 6-month follow-up period after study enrollment. Independent variables included socioeconomic status, social, health, housing, and prior criminal justice involvement.Key ResultsParticipants had a median age of 58 years and were predominantly men (75%) and Black (80%). Seventy percent had at least one chronic medical condition, 12% reported heavy drinking, and 38% endorsed moderate-severe use of cocaine, 8% of amphetamines, and 7% of opioids. At baseline, 84% reported a lifetime history of jail stays; 37% reported prior prison stays. During follow-up, 23% spent time in jail or prison. In multivariable models, factors associated with a higher risk of incarceration included the following: having 6 or more confidants (HR=2.13, 95% CI=1.2–3.7, p=0.007), remaining homeless (HR=1.72, 95% CI=1.1–2.8, p=0.02), heavy drinking (HR=2.05, 95% CI=1.4–3.0, p<0.001), moderate-severe amphetamine use (HR=1.89, 95% CI=1.2–3.0, p=0.006), and being on probation (HR=3.61, 95% CI=2.4–5.4, p<0.001) or parole (HR=3.02, 95% CI=1.5–5.9, p=0.001).ConclusionsOlder adults experiencing homelessness have a high risk of incarceration. There is a need for targeted interventions addressing substance use, homelessness, and reforming parole and probation in order to abate the high ongoing risk of incarceration among older adults experiencing homelessness.KEY WORDS: incarceration, homelessness, vulnerable populations     

Ambulatory Patients with Cardiometabolic Disease and Without Evidence of COVID-19 During the Pandemic. The CorCOVID LATAM Study

Background:SARS-CoV-2 pandemic has modified the cardiovascular care of ambulatory patients. The aim of this survey was to study changes in lifestyle habits, treatment adherence, and mental health status in patients with cardiometabolic disease, but no clinical evidence of COVID-19.Methods:A cross-sectional survey was conducted in ambulatory patients with cardiometabolic disease using paper/digital surveys. Variables investigated included socioeconomic status, physical activity, diet, tobacco use, alcohol intake, treatment discontinuation, and psychological symptoms.Results:A total of 4,216 patients (50.9% males, mean age 60.3 ± 15.3 years old) from 13 Spanish-speaking Latin American countries were enrolled. Among the study population, 46.4% of patients did not have contact with a healthcare provider, 31.5% reported access barriers to treatments and 17% discontinued some medication. Multivariate analysis showed that non-adherence to treatment was more prevalent in the secondary prevention group: peripheral vascular disease (OR 1.55, CI 1.08–2.24; p = 0.018), heart failure (OR 1.36, CI 1.05–1.75; p = 0.017), and coronary artery disease (OR 1.29 CI 1.04–1.60; p = 0.018). No physical activity was reported by 38% of patients. Only 15% of patients met minimum recommendations of physical activity (more than 150 minutes/week) and vegetable and fruit intake. Low/very low income (45.5%) was associated with a lower level of physical activity (p < 0.0001), less fruit and vegetables intake (p < 0.0001), more tobacco use (p < 0.001) and perception of depression (p < 0.001). Low educational level was also associated with the perception of depression (OR 1.46, CI 1.26–1.70; p < 0.01).Conclusions:Patients with cardiometabolic disease but without clinical evidence of COVID-19 showed significant medication non-adherence, especially in secondary prevention patients. Deterioration in lifestyle habits and appearance of depressive symptoms during the pandemic were frequent and related to socioeconomic status.     

Red blood cell distribution width is associated with adverse cardiovascular events after septal myectomy

BackgroundRed blood cell distribution width (RDW) is associated with increased morbidity and mortality in several cardiovascular diseases. However, the prognostic significance of RDW in patients with hypertrophic obstructive cardiomyopathy (HOCM) who underwent septal myectomy remains unclear as no studies have been conducted on this topic. This study aimed to assess the prognostic significance of RDW in these patients.MethodsA total of 867 adults with HOCM who underwent septal myectomy at Fuwai Hospital from 2011 to 2017 were retrospectively studied. All patients were assessed comprehensively, including their medical history, echocardiograms, and blood test results.ResultsThe median age of patients was 47.9 [interquartile range (IQR), 37.0–56.0] years and 61.5% of patients were men. During a median follow-up period of 32 (IQR, 17–53) months, 26 patients died and 23 had a cardiovascular death during follow-up. Compared to patients in the lowest RDW quartile, those in the highest quartile had a significantly lower 5-year survival free from all-cause and cardiovascular death (95.9% vs. 87.6%, P<0.001; 95.9% vs. 89.9%, P<0.001). Compared with lower RDW, higher RDW was significantly associated with all-cause and cardiovascular death after adjustment for age, sex, body mass index, and relevant clinical risk factors [per RDW standard deviation (SD) hazard ratio (HR) increase =1.76, 95% confidence interval (CI): 1.54–2.05, P<0.001; per RDW SD HR =1.91, 95% CI: 1.63–2.22, P for trend <0.001].ConclusionsHigher RDW is independently associated with all-cause and cardiovascular death in patients with HOCM after septal myectomy. Therefore, this readily available biomarker could be considered as an additive biomarker for risk stratification in these patients.     

O Escore Gensini e a Carga Trombótica Adicionam Valor Preditivo ao Escore SYNTAX na Detecção de No-Reflow após Infarto do Miocárdio

Background No-reflow after percutaneous coronary intervention is associated with poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). SYNTAX score is a good predictor of no-reflow.Objective We aimed to evaluate whether atherosclerotic burden (Gensini score) and thrombus burden in the culprit coronary artery would improve the ability of the SYNTAX score to detect no-reflow.Methods In this prospective cohort study, consecutive patients with STEMI who presented within 12 h of onset of symptoms were selected for this study. No-reflow was defined as TIMI flow < 3 o r TIMI flow = 3 but myocardial blush grade <2. Thrombus burden was quantified according to the TIMI thrombus grade scale (0 to 5).Results A total of 481 patients were included (mean age 61±11 years). No-reflow occurred in 32.8%. SYNTAX score (OR=1.05, 95%CI 1.01–1.08, p<0.01), thrombus burden (OR=1.17, 95%CI 1.06–1.31, p<0.01), and Gensini score (OR=1.37, 95%CI 1.13–1.65, p<0.01) were independent predictors of no-reflow. Combined scores had a larger area under the curve than the SYNTAX score alone (0.78 [0.73–0.82] vs 0.73 [0.68–0.78], p=0.03). Analyses of both categorical (0.11 [0.01–0.22], p=0.02), and continuous net reclassification improvement (NRI>0) (0.54 [0.035–0.73], p<0.001) showed improvement in the predictive ability of no-reflow in the combined model, with integrated discrimination improvement (IDI) of 0.07 (0.04–0.09, p<0.001).Conclusions Our findings suggest that, in patients with STEMI undergoing percutaneous coronary intervention, atherosclerotic burden and thrombus burden in the culprit artery add predictive value to the SYNTAX score in detecting the no-reflow phenomenon.
