Joint effect of physical activity and blood lipid levels on all-cause and cardiovascular disease mortality: The Rural Chinese Cohort Study

Background and aimsWe aimed to evaluate the joint effect of physical activity (PA) and blood lipid levels on all-cause and cardiovascular disease (CVD) mortality.Methods and resultsWe analyzed 17,236 participants from the Rural Chinese Cohort Study. Cox's proportional-hazards regression models were used to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) between the joint effect of PA and blood lipid levels and risk of all-cause and CVD mortality. Restricted cubic splines were used to estimate the dose–response relationship of PA with risk of all-cause and CVD mortality. During a median follow-up of 6.01 years there were 1106 deaths (484 from CVD) among participants. For all-cause mortality, compared with the group with dyslipidemia and extremely light PA (ELPA), the HRs with dyslipidemia and light PA (LPA), moderate PA (MPA), and heavy PA (HPA) were 0.56 (95% CI 0.45–0.70), 0.59 (0.46–0.75), and 0.59 (0.45–0.78), respectively, while the HRs of groups with normal lipid levels and ELPA, LPA, MPA, and HPA were 0.88 (0.72–1.04), 0.59 (0.48–0.73), 0.53 (0.41–0.67), and 0.38 (0.29–0.50), respectively. We observed similar effects on CVD mortality. Restricted cubic splines showed a curvilinear relationship between PA and risk of all-cause and CVD mortality with normal lipid levels and with dyslipidemia.ConclusionHigher PA reduces the risk of all-cause and CVD mortality. Higher levels of PA are needed in the population.     

Mortality in diabetes compared with previous cardiovascular disease: A gender-specific meta-analysis

AimsDiabetes has been described as a cardiovascular disease (CVD) risk equivalent. There is evidence, however, that its impact may differ between women and men. For this reason, our study aimed to obtain gender-specific hazard ratios (HRs) comparing diabetes and CVD patients in terms of all-cause, CVD and coronary heart disease (CHD) mortality.MethodsIndividuals with diabetes (without CVD) and those with CVD (without diabetes) were examined through a systematic review of articles that provided gender-specific HRs for mortality. Searches included Medline, Embase and the Cochrane Library database (from January 1998 to December 2009) and exploded MeSH headings [cardiovascular diseases, risk, epidemiologic studies, case-control studies, cohort studies, mortality, outcome assessment (health care), sex factors, survival analysis and diabetes mellitus, type 2]. Two observers selected and reviewed the studies and hierarchical Bayesian random-effects models were used to combine HRs, thereby accommodating any between-study differences through inclusion of a between-study variance in HRs.ResultsOut of 5425 studies, nine were relevant (0.17%). CVD and CHD mortality in men was lower for diabetes alone (CVD mortality HR: 0.82, 95% CrI: 0.69–0.98; CHD mortality HR: 0.73, 95% CrI: 0.65–0.83). In contrast, rates appeared to be higher in women with diabetes alone (CVD mortality HR: 1.29, 95% CrI: 0.79–2.26; CHD mortality HR: 1.28, 95% CrI: 0.75–2.22), although wide credible intervals precluded any definitive conclusions. All-cause mortality in men was similar for diabetes and previous CVD (HR: 1.02, 95% CrI: 0.93–1.12) whereas, among women, it was at least as high and possibly higher for diabetes alone (HR: 1.25, 95% CrI: 0.89–1.76).ConclusionCompared with previous CVD, diabetes alone leads to lower CVD and CHD mortality risk in men, and similar all-cause mortality. In contrast, although further studies are needed, it is possible that diabetes leads to higher CVD, CHD and all-cause mortality in women.     

Coffee consumption and cardiovascular diseases and mortality in patients with type 2 diabetes: A systematic review and dose–response meta-analysis of cohort studies

AimsTo evaluate the long-term consequences of coffee drinking in patients with type 2 diabetes.Data synthesisPubMed, Scopus, and Web of Sciences were searched to November 2020 for prospective cohort studies evaluating the association of coffee drinking with risk of cardiovascular disease (CVD) and mortality in patients with type 2 diabetes. Two reviewers extracted data and rated the certainty of evidence using GRADE approach. Random-effects models were used to estimate the hazard ratios (HRs) and 95% CIs. Dose–response associations were modeled by a one-stage mixed-effects meta-analysis. Ten prospective cohort studies with 82,270 cases were included. Compared to those with no coffee consumption, the HRs for consumption of 4 cups/d were 0.79 (95%CI: 0.72, 0.87; n = 10 studies) for all-cause mortality, 0.60 (95%CI: 0.46, 0.79; n = 4) for CVD mortality, 0.68 (95%CI: 0.51, 0.91; n = 3) for coronary heart disease (CHD) mortality, 0.72 (95%CI: 0.54, 0.98; n = 2) for CHD, and 0.77 (95%CI: 0.61, 0.98; n = 2) for total CVD events. There was no significant association for cancer mortality and stroke. There was an inverse monotonic association between coffee drinking and all-cause and CVD mortality, and inverse linear association for CHD and total CVD events. The certainty of evidence was graded moderate for all-cause mortality, and low or very low for other outcomes.ConclusionsDrinking coffee may be inversely associated with the risk of mortality in patients with type 2 diabetes. However, more research is needed considering type of coffee, sugar and cream added to coffee, and history of CVD to present more confident results.Registry and registry numberThe protocol of this systematic review was registered at Open Science Framework (https://osf.io/8uaf3, registered form: osf.io/xur76, registration DOI: 10.17605/OSF.IO/8UAF3).     

Erratum to “The growing interest of fibrin imaging in atherosclerosis” [Atherosclerosis 222 (1) (2012) 22–25]

ObjectiveHigh-density lipoprotein cholesterol (HDL) and physical fitness (PF) have both been shown to predict cardiovascular disease (CVD), particularly coronary heart disease (CHD). Increased PF is associated with increased HDL and may partly explain the benefit of HDL. We tested the hypothesis that PF influences the prognostic impact of HDL for CHD and also for CHD-, CVD- and all-cause death.MethodsHDL was measured 1979–1982 in 1357 healthy men aged 44–69 years followed up to 28 years. PF was measured using bicycle exercise test. Hazard ratios (HRs) adjusted for age, smoking, systolic blood pressure, and total cholesterol and further for PF between HDL quartiles were calculated using Cox proportional survival model.ResultsThe highest HDL quartile was associated with lower risk of CHD (HR: 0.57, 95% confidence interval [CI]: 0.43–0.74), fatal CHD (HR: 0.56, CI: 0.36–0.86), fatal CVD (HR: 0.64, CI: 0.46–0.88) and all-cause death (HR: 0.80, CI: 0.65–0.99) compared to the lowest quartile. Adjustments for PF or changes in PF over 8.6 years did not change the results except for all-cause death, which was not significantly different between HDL quartiles. We found no interaction between HDL and PF.ConclusionsHDL is a strong predictor of long term risk of CHD, fatal CHD and fatal CVD in healthy middle-aged men. Physical fitness or its changes had no impact on the ability of HDL to predict CHD.     

Remnant cholesterol as a risk factor for all-cause and cardiovascular mortality in incident peritoneal dialysis patients

Background and aimsRemnant cholesterol (RC) adversely contributes to cardiovascular disease (CVD) and overall survival in various diseases. However, its role in CVD outcomes and all-cause mortality in patients undergoing peritoneal dialysis (PD) is limited. Therefore, we aimed to investigate the association between RC and all-cause and CVD mortality in patients undergoing PD.Methods and resultsBased on lipid profiles recorded using standard laboratory procedures, fasting RC levels were calculated in 2710 incident patients undergoing PD who were enrolled between January 2006 and December 2017 and followed up until December 2018. Patients were divided into four groups according to the quartile distribution of baseline RC levels (Q1: <0.40 mmol/L, Q2: 0.40 to <0.64 mmol/L, Q3: 0.64 to <1.03 mmol/L, and Q4: ≥1.03 mmol/L). Associations between RC and CVD and all-cause mortality were evaluated using multivariable Cox models. During the median follow-up period of 35.4 months (interquartile range, 20.9–57.2 months), 820 deaths were recorded, of which 438 were CVD-related. Smoothing plots showed non-linear relationships between RC and adverse outcomes. The risks of all-cause and CVD mortality increased progressively through the quartiles (log-rank, p < 0.001). Using adjusted proportional hazard models, a comparison of the highest (Q4) to lowest (Q1) quartiles revealed significant increases in the hazard ratio (HR) for all-cause mortality (HR 1.95 [95% confidence interval (CI), 1.51–2.51]) and CVD mortality risk (HR 2.60 [95% CI, 1.80–3.75]).ConclusionAn increased RC level was independently associated with all-cause and CVD mortality in patients undergoing PD, suggesting that RC was important clinically and required further research.     

Metformin combined with dipeptidyl peptidase-4 inhibitors or metformin combined with sulfonylureas in patients with type 2 diabetes: A real world analysis of the South Korean national cohort

AimsWe explored the risks associated with metformin plus sulfonylurea (MET + SU) or MET plus a dipeptidyl peptidase-4 inhibitor (MET + DPP4i) for hypoglycemia, cardiovascular disease (CVD) events and all-cause mortality in type 2 diabetes (T2D) patients with comorbidities.MethodsThis retrospective cohort study is based on the South Korean National Health Insurance Service–National Sample Cohort, enrolling T2D patients with one or more diabetes-related comorbidities who switched from monotherapy to MET + SU or MET + DPP4i between July 1, 2008 and December 31, 2013. The risk of hypoglycemia, CVD events and all-cause mortality was examined using Cox's proportional hazard modeling and propensity score matching.ResultsOverall, 5693 patients with a mean of 2.6 comorbidities in addition to diabetes were included. Compared with MET + SU, MET + DPP4i treatment was associated with a lower risk of hypoglycemia, CVD events and all-cause mortality; adjusted HRs (95% CI), 0.39 (0.18–0.83), 0.72 (0.54–0.97), and 0.64 (0.39–1.05), respectively. Propensity score matching showed comparable results. In further subgroup analyses according to comorbidity type and number, MET + DPP4i was associated with less CVD events and all-cause mortality compared to MET + SU. This increased with more complex comorbid status.ConclusionsIn T2D patients with comorbidities, MET + DPP4i treatment is associated with lower risks of CVD events and all-cause mortality compared with MET + SU, independent of type or number of comorbidities. A more complex comorbid status further increases this effect.     

Statin adherence and risk of all-cause,cancer, and cardiovascular mortality among dyslipidemia patients: A time-dependent analysis

Background and aimResults have been mixed and uncertainty still remains regarding the impact of statin adherence on premature deaths. Thus, we investigated the association between statin adherence and risks of all-cause, cancer, and cardiovascular mortality among dyslipidemia patients in South Korea.Methods and resultsWe used data from the National Health Insurance Service (NHIS) National Sample Cohort for the years 2003–2013, which included data on 107,954 middle-aged and elderly dyslipidemia patients. Among these patients, a time-dependent Cox proportional hazards model was used to estimate the hazard ratios (HRs) of all-cause, cancer, and cardiovascular mortality depending on proportion of days covered (PDC) by statin medication. A total of 3073 (2.85%) individuals died within the study period. Of these individuals, 1143 (1.06%) died from cancer, and 687 (0.64%) died from cardiovascular diseases. Relative to good medication adherence (>80%), moderate (50–80%) (hazard ratio [HR]: 1.28, 95% confidence interval [CI]: 1.14–1.43) and poor (<50%) (HR: 1.58, 95% CI: 1.41–1.78) adherence were associated with increased risk of all-cause mortality. Poor adherence was also associated with increased risk of cancer (HR: 1.33, 95% CI: 1.16–1.52) and cardiovascular (HR: 1.27, 95% CI: 1.06–1.51) mortality.ConclusionSuch findings reveal that relative to good statin adherence, moderate and/poor adherence is associated with increased risks of all-cause, cancer, and cardiovascular mortality. Clinicians should assess for dyslipidemia, link statin adherence problems to potential mortality risk, and monitor outcomes in both medication adherence and disease complications.     

Prognostic value of adiponectin for cardiovascular disease and mortality

CONTEXT: Low adiponectin concentrations are associated with the presence of an adverse cardiovascular disease (CVD) risk profile. OBJECTIVE: We studied the predictive value of adiponectin levels for all-cause and CVD mortality and CVD morbidity. DESIGN, SETTING, AND PARTICIPANTS: This was a population-based cohort study in Hoorn, The Netherlands, which started in 1989 and included 2484 participants, aged 50-75 yr. MAIN OUTCOME MEASURES: Hazard ratios (HRs) with 95% confidence interval per sd change in log-adiponectin for all-cause and CVD mortality and CVD morbidity were calculated. RESULTS: Adiponectin was determined for 1077 men and 1248 women. Higher adiponectin reduced the risk of nonfatal CVD in women [HR with 95% confidence interval 0.72 (0.61-0.90) in women and 0.92 (0.79-1.06) in men], but not the risk of all-cause or CVD mortality. In contrast, after adjustment for cardiovascular risk factors, higher adiponectin was a significant predictor of all-cause and CVD mortality [HR for CVD mortality 1.45 (1.10-1.92) in women and 1.30 (1.04-1.63) in men]. Higher adiponectin was associated with an increased risk of CVD mortality in people with prevalent CVD [HR 1.27 (0.98-1.63)] and with reduced risk in people without [HR 0.90 (0.73-1.11)]. After adjustment for cardiovascular risk factors, the HRs for CVD mortality were 1.60 (1.14-2.23) for patients with and 1.38 (1.06-1.80) for patients without prevalent CVD. CONCLUSIONS: High levels of adiponectin predict mortality, in particular in patients with prevalent CVD. We hypothesize that adiponectin protects against metabolic and vascular diseases, but in patients already afflicted with CVD, adiponectin is compensatory up-regulated and, therefore, indicates a high mortality risk.     

Uric acid is not an independent predictor of cardiovascular mortality in type 2 diabetes: a population-based study

ObjectiveAlthough some studies have suggested that uric acid is a risk factor for mortality, this relationship is still uncertain in people with type 2 diabetes.MethodsThe study base was the population-based cohort of 1540 diabetic subjects (median age 68.9 years) of the Casale Monferrato Study. The role of serum uric acid on 15-years all-cause, cardiovascular and non-cardiovascular mortality was assessed by multivariate Cox proportional hazards modeling.ResultsBaseline levels of serum uric acid were negatively correlated with HbA1c, were higher in men and in the elderly and were independently associated with components of the metabolic syndrome. Out of 14,179 person-years, 1000 deaths (514 due to cardiovascular diseases) were observed. Compared to the lower quartile of uric acid, HRs (95% CI) in the upper quartile were 1.47 (1.22–1.76) for all-cause mortality; 1.40 (1.09–1.80) for cardiovascular mortality and 1.50 (1.15–1.96) for non-cardiovascular mortality. In multiple adjusted models, however, HRs were 1.30 (1.06–1.60) for all-cause mortality, 1.13 (0.85–1.50) for cardiovascular mortality and 1.50 (1.11–2.02) for non-cardiovascular mortality (men 1.87, 1.19–2.95; women 1.20, 0.80–1.80); the latter appeared to be due to neoplastic diseases (HR in all combined quartiles vs. lower quartile: both sexes 1.59, 1.05–2.40; men 1.54, 0.83–2.84, women 1.68, 0.95–2.92).ConclusionsIn diabetic people, uric acid is associated with components of the metabolic syndrome but it may not be accounted as an independent risk factor for cardiovascular mortality. The increased all-cause mortality risk with higher levels of uric acid might be due to increased neoplastic mortality and deserves future studies.     

A Body Shape Index is positively associated with all-cause and cardiovascular disease mortality in the Chinese population with normal weight: A prospective cohort study

Background and aimA body shape index (ABSI) is a valuable predictor of mortality in the Western population, but similar evidence in the general Chinese population is limited. This study aims to evaluate the association between the ABSI and all-cause and cardiovascular disease (CVD) mortality in the Chinese population with normal weight.Methods and results9046 participants with normal BMI (18.5–24.9 kg/m²) from the China Hypertension Survey were enrolled. The baseline ABSI was calculated as waist circumference/(BMI^2/3height^1/2). Cox proportional hazards regression was performed to evaluate the association of the ABSI with all-cause and CVD mortality. Over an average follow-up of 5.4 years, 686 all-cause and 215 CVD deaths occurred. A 0.01-unit increment in the ABSI was associated with a 31% greater risk of all-cause mortality (hazard ratio [HR], 1.31; 95% CI: 1.12, 1.48) and CVD mortality (HR, 1.30; 95% CI: 1.08, 1.58). Compared with quartile 1 of the ABSI, the adjusted HRs of all-cause mortality for quartiles 2–4 were, respectively, 1.25 (95% CI: 0.98, 1.59), 1.28 (95% CI: 0.99, 1.67), and 1.54 (95% CI: 1.17, 2.03) (P_trend = 0.004), and those of CVD mortality for quartiles 2–4 were, respectively, 1.28 (95% CI: 0.88, 1.83), 1.42 (95% CI: 0.97, 2.08), and 1.45 (95% CI: 0.98, 2.170) (P_trend = 0.043). The dose–response analysis showed a linear positive association of the ABSI with all-cause (P_nonlinearity = 0.158) and CVD mortality (P_nonlinearity = 0.213).ConclusionThe ABSI was positively associated with all-cause and CVD mortality among the general Chinese population with normal BMI. The data suggest that the ABSI may be an effective tool for central fatness for mortality risk assessment.     

Análisis de la relación dosis-respuesta de la actividad física recreativa con los eventos cardiovasculares y la mortalidad por todas las causas: el estudio REGICOR

Introduction and objectivesRegular leisure-time physical activity (LTPA) has been consistently recognized as a protective factor for cardiovascular diseases (CVD) and all-cause mortality. However, the pattern of this relationship is still not clear. The aim of this study was to assess the relationship of LTPA with incident CVD and mortality in a Spanish population.MethodsA prospective population-based cohort of 11 158 randomly selected inhabitants from the general population. LTPA was assessed by a validated questionnaire. Mortality and CVD outcomes were registered during the follow-up (median: 7.24 years). The association between LTPA and outcomes of interest (all-cause mortality and cardiovascular disease) was explored using a generalized additive model with penalized smoothing splines and multivariate Cox proportional hazard models.ResultsWe observed a significant nonlinear association between LTPA and all-cause and CVD mortality, and fatal and nonfatal CVD. Moderate-vigorous intensity LTPA, but not light-intensity LTPA, were associated with beneficial effects. The smoothing splines identified a cutoff at 400 MET-min/d. Below this threshold, each increase of 100 MET-min/d in moderate-vigorous LTPA contributed with a 16% risk reduction in all-cause mortality (HR, 0.84; 95%CI, 0.77-0.91), a 27% risk reduction in CVD mortality (HR, 0.73; 95%CI, 0.61-0.87), and a 12% risk reduction in incident CVD (HR, 0.88; 95%CI, 0.79-0.99). No further benefits were observed beyond 400 MET-min/d.ConclusionsOur results support a nonlinear inverse relationship between moderate-vigorous LTPA and CVD and mortality. Benefits of PA are already observed with low levels of activity, with a maximum benefit around 3 to 5 times the current recommendations.Full English text available from:www.revespcardiol.org/en     

Changes in serum uric acid and the risk of cardiovascular disease and all-cause mortality in the general population

Background and aimLongitudinal evidence on change in serum (SUA) with risk of cardiovascular disease (CVD) and all-cause mortality is limited, as many prior studies focused on baseline SUA. Further, the optimal threshold range of SUA change is unclear.Methods and resultsA total of 63,127 participants without history of CVD were enrolled. Change in SUA was determined by the difference of SUA levels between 2006 and 2010, which divided by baseline SUA was percent change in SUA. Multivariable Cox proportional hazards models were used to calculated the hazard ratios (HRs) and 95% confidence intervals (CIs). Our analysis also included restricted cubic spline model and three-piecewise Cox proportion hazards model to address the non-linearity between percent change in SUA and outcomes. During a median follow-up of 7.04 years, 3341 CVD and 3238 deaths occurred. We did not observed a significant association between changes in SUA and CVD. However, changes in SUA at extreme were associated with higher risk of all-cause mortality, the HRs (95% CIs) were 1.15 (1.02–1.29) and 1.20 (1.06–1.35) in the first and fifth quintile group, compared with the third quintile group. We further found a U-shaped association between percent change in SUA and all-cause mortality, and the optimal range was within 20%.ConclusionsChanges in SUA at extreme were risk factors for all-cause mortality, but not for CVD in the general population. The findings are relevant for role of SUA in the management of CVD risk and may contribute to improve identification of patients at higher risk.     

Influence of diabetes on cardiac resynchronization therapy with or without defibrillator in patients with advanced heart failure

ObjectivesWe performed a post hoc analysis to determine the influence of cardiac resynchronization therapy with a defibrillator (CRT-D) or without a defibrillator (CRT-P) on outcomes among diabetic patients with advanced heart failure (HF).BackgroundIn patients with systolic HF, diabetes is an independent predictor of morbidity and mortality. No data are available on its impact on CRT-D or CRT-P in advanced HF.MethodsThe database of the Comparison of Medical Therapy, Pacing and Defibrillation in Heart Failure trial was examined to determine the influence of CRT (CRT-D and CRT-P) on outcomes among diabetic patients. All-cause mortality or hospitalization, all-cause mortality or cardiovascular hospitalization, all-cause mortality or HF hospitalization, and all-cause mortality were analyzed among diabetic patients (n = 622). A Cox proportional hazard model, adjusting for age, gender, New York Heart Association, ischemic status, body mass index, left ventricular ejection fraction, heart rate, QRS, left or right bundle branch block, blood pressure, comorbidities (renal failure, carotid artery disease, peripheral vascular disease, hypertension, coronary artery bypass grafting, and atrial fibrillation), medications, and device (with or without defibrillator), was used to estimate hazard ratios (HRs) and significance.ResultsThe overall outcome of diabetic patients was similar to that of nondiabetic patients in the optimal pharmacologic therapy arm. With CRT, diabetic patients experienced a substantial reduction in all-cause mortality or all-cause hospitalization (HR = 0.77, 95% confidence interval [CI] 62–0.97), all-cause mortality or cardiovascular hospitalization (HR = 0.67, 95% CI 0.53–0.85), all-cause mortality or HF hospitalization (HR = 0.52, 95% CI 0.40–0.69), and all-cause mortality (HR = 0.67, 95% CI 0.45–0.99) compared with optimal pharmacologic therapy. Procedure-related complications and length of stay were identical in diabetic and nondiabetic patients.ConclusionIn diabetic patients with advanced HF, there is a substantial benefit from device therapy with significant improvement in all end points.     

Hypertension, concurrent cardiovascular risk factors and mortality: the Singapore Cardiovascular Cohort Study

The current hypertension (HTN) guidelines recommend the assessment of other cardiovascular disease (CVD) risk factors in individuals with HTN for further management. Few studies in Asian populations have been published to identify the outcome of individuals with HTN and other CVD risk factors. This study aims to assess the effect of HTN alone, and in combination with other CVD risk factors on all-cause and CVD mortality. Three cross-sectional studies carried out in Singapore (baseline 1982--1995) consisting of 5830 persons were grouped by the absence or presence of HTN and CVD risk factors. They were followed-up (mean 14.1 years) by linkage with the National Death Register. Cox's proportional hazards model was used to obtain adjusted hazard ratios (HRs) for risk of mortality. HTN individuals with either <2 CVD risk factors (adjusted HR 1.4; 95% confidence interval (CI) 1.0-1.8) or > or =2 CVD risk factors (adjusted HR 2.3; 95% CI 1.9-3.0) were at increased risk of all-cause mortality compared to normotensive individuals. The findings were similar for CVD mortality. HTN individuals who also smoked or had diabetes were at highest risk of all-cause mortality, whereas those with elevated total cholesterol/high-density lipoprotein cholesterol, smoked or diabetes had the highest risk for CVD mortality. These findings show that in HTN individuals it is important to assess the presence of other CVD risk factors and manage accordingly.     

Association between the visceral adiposity index and risks of all-cause and cause-specific mortalities in a large cohort: Findings from the UK biobank

Background and aimsThe visceral adiposity index (VAI) has been recently established as a measure of visceral fat distribution and is shown to be associated with a wide range of adverse health events. However, the precise associations between the VAI score and all-cause and cause-specific mortalities in the general population remain undetermined.Methods and resultsIn this large-scale prospective epidemiological study, 357,457 participants (aged 38–73 years) were selected from the UK Biobank. We used Cox competing risk regression models to estimate the association between the VAI score and all-cause, cardiovascular disease (CVD), cancer, and other mortalities. The VAI score was significantly correlated with an increased risk of all-cause mortality (hazard ratio [HR], 1.200; 95% confidence interval [CI], 1.148–1.255; P < 0.0001), cancer mortality (HR, 1.224; 95% CI, 1.150–1.303; P < 0.0001), CVD mortality (HR, 1.459; 95% CI, 1.148–1.255; P < 0.0001), and other mortalities (HR, 1.200; 95% CI, 1.148–1.255; P < 0.0001) after adjusting for a series of confounders. In addition, the subgroup analyses showed that HRs were significantly higher in participants who were male, aged below 65 years, and body mass index less than 25.ConclusionIn summary, VAI was positively associated with an increased risk of all-cause and cause-specific mortalities in a nationwide, well-characterised population identified in a UK Biobank. The VAI score might be a complementary traditional predictive indicator for evaluating the risk of adverse health events in the population of Western adults aged 38 years and older.     

Impaired glucose tolerance predicts all-cause mortality among older men at high risk for cardiovascular disease in China

AimsTo investigate the potential association between impaired glucose tolerance (IGT) and all-cause mortality among older men at high risk for cardiovascular disease (CVD) in China.MethodsIn this prospective observational study, 460 older men aged ≥60 years were determined to have either IGT or normal glucose tolerance (NGT) based on an oral glucose tolerance test conducted between May 2005 and May 2007. IGT and NGT were diagnosed according to the 1999 WHO diagnostic criteria. All subjects were followed until March 2017. The primary outcome studied was all-cause mortality. Multivariate Cox models were used to estimate relative risk for all-cause mortality.ResultsDuring a mean follow-up of 11.2 years, forty-three (21.4%) subjects in the IGT group and twenty-nine (11.2%) subjects in the NGT group died (HR 2.05, 95% CI 1.28–3.28, P = 0.003). Multivariate Cox proportional-hazards analysis demonstated that IGT was significantly associated with increased risk for all-cause mortality, composite cardiovascular outcome, nonfatal stroke and heart failure after adjusting for potential confounding factors. Logistic regression analysis showed that IGT at baseline (P < 0.05) rather than incident type 2 diabetes was a risk factor of all-cause mortality.ConclusionsIGT was significantly associated with all-cause mortality in older Chinese men at high risk for CVD.     

Prognostic implications of adherence to oral anticoagulants among patients with atrial fibrillation: Insights from MISOAC-AF trial

ObjectivesTo explore the implications of adherence to oral anticoagulants (OACs) on all-cause mortality and cardiovascular outcomes in patients with atrial fibrillation (AF).MethodsThis post-hoc analysis of the MISOAC-AF trial included recently hospitalized patients with AF. Adherence to OACs was assessed by the proportion of days covered (PDC). Good adherence was defined as PDC >80 %. Cox regression models were used to associate PDC with clinical outcomes of all-cause death, cardiovascular death (CVD), stroke, and bleeding. A sub-analysis was performed among adherent patients to compare outcomes between vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs).ResultsDuring a median 31-month follow-up, 778 cardiac patients with comorbid AF who had been prescribed OACs upon hospital discharge were studied. The mean PDC was 0.78; 66 % of patients had good adherence (>80 %) which was associated with lower risk of all-cause death [adjusted hazard ratio (aHR): 0.64; 95 % confidence interval (CI): 0.46 to 0.84, p < 0.001] and CVD (aHR: 0.70; 95 % CI: 0.50 to 0.97, p = 0.03). The risk of stroke and major or non-major bleeding did not differ by adherence status. Among adherent patients to OACs, VKA use was associated with higher rates of all-cause death (p < 0.001), CVD (p < 0.001), and stroke (p = 0.01); no differences were found regarding major or non-major bleeding risk.ConclusionsIn recently hospitalized patients with AF, good adherence to OACs was associated with a reduced risk of all-cause death and CVD. The rates of stroke or bleeding events were not significantly different. VKAs were associated with more adverse events compared to DOACs.     

Complete Revascularization in Patients With STEMI and Multi-Vessel Disease: A Meta-Analysis of Randomized Controlled Trials

BackgroundPercutaneous coronary intervention (PCI) is the treatment of choice for ST-elevation myocardial infarction (STEMI). However, efficacy of complete vs culprit only revascularization in patients with STEMI and multivessel disease remains unclear.MethodsWe searched PubMed/MEDLINE, and Cochrane library. The primary endpoint was major adverse cardiovascular events (MACE). Secondary outcomes were all-cause mortality, cardiovascular mortality, myocardial infarction (MI), repeat revascularization, stroke, major bleeding, and contrast induced nephropathy. Estimates were calculated as random effects hazard ratios (HRs) with 95% confidence intervals (CI).ResultsTwelve trials with 7592 patients were included. There was a significantly lower risk of MACE [HR 0.61; 95% CI (0.43–0.60); p = 0.0009; I² = 72%], cardiovascular mortality [HR 0.74; 95% CI (0.56–0.99); p = 0.04; I² = 2%], and repeat revascularization [HR 0.43; 95% CI (0.31–0.59); p < 0.00001; I² = 67%] in patients treated with complete compared with culprit-only revascularization. There was no statistically significant difference in MI [HR 0.77; 95% CI (0.52–1.12); p = 0.17; I² = 49%], all-cause mortality [HR 0.86; 95% CI (0.65–1.13); p = 0.28; I² = 14%], heart failure [HR 0.82 95% CI (0.51–1.32); p = 0.42; I² = 26%], major bleeding [HR 1.07; 95% CI (0.66–1.75); p = 0.78; I² = 25%], stroke [HR 0.67; 95% CI (0.24–1.89); p = 0.45; I² = 54%], or contrast induced nephropathy, although higher contrast volumes were used in the complete revascularization group [HR 1.22; 95% CI (0.78–1.92); p = 0.39; I² = 0%].ConclusionComplete revascularization was associated with a significantly lower risk of MACE, cardiovascular mortality, and repeat revascularization compared with culprit-only revascularization. These results suggest complete revascularization with PCI following STEMI and multivessel disease should be considered.     

Impact of atrial fibrillation on stroke,heart failure,and mortality in diabetic patients with coronary artery disease

PurposeThe objective of this study was to evaluate the risk of stroke, heart failure (HF) and mortality in diabetic patients with coronary artery disease (CAD) with a diagnosis of atrial fibrillation (AF).MethodsThe study population was identified as the diabetic patients presented with CAD from 2000 to 2011 and the case group was those with a diagnosis of AF whereas the control group did not have AF. The cumulative incidence of stroke, heart failure and mortality was demonstrated by Kaplan-Meier curves and the difference between the two groups was estimated by log-rank test. The Cox proportional hazard model was used to calculate the risk of the factors to the event, and the results were expressed by hazard ratios (HRs) and 95% confidence intervals (95% CIs).ResultsAfter controlling for the covariates, the risk of stroke, heart failure and mortality was 1.63-fold higher (adjusted HR =1.63, 95% CI =1.37-1.94) , 2.75-fold higher (adjusted HR = 2.75, 95% CI =2.25-3.36), 1.72-fold higher (adjusted HR = 1.72, 95% CI = 1.43-2.07) in the AF cohort compared to the non-AF cohort.ConclusionAfter adjusting for the confounding factors, increased risk of stroke, heart failure, and mortality by 1.63, 2.75, 1.72 times with a concomitant diagnosis of AF in diabetic CAD patients was observed in this study.     

Serum uric acid as a risk factor of all-cause mortality and cardiovascular events among type 2 diabetes population: Meta-analysis of correlational evidence

AimsTo explore the association between serum uric acid (SUA) level and the risk of cardiovascular complications and all-cause mortality rates among individuals with type 2 diabetes.MethodsWeb of Science and PubMed database were searched for studies reported associations between SUA level and cardiovascular complications and all-cause mortality among individuals with type 2 diabetes. Hazard ratios (HRs) were independently extracted by two investigators and synthesized through meta-analysis across selected studies.Results6 (n = 11,750 patients), 4 (n = 3044 patients) and 2 studies (n = 7792 patients) were identified reporting associations between SUA level and all-cause mortality, coronary heart disease (CHD) and stroke respectively. HR for all-cause mortality, CHD, and stroke per 59 μmol/l increase was 1.06 (95% CI: 1.03, 1.09), 1.09 (95% CI: 0.94, 1.26) and 1.19 (95% CI: 1.08, 1.31), respectively.ConclusionsOverall, the SUA level was associated with a higher risk of all-cause mortality and stroke. We found no significant association between SUA level and CHD among type 2 diabetes population.
