Association between food and nutrients intakes and coronary plaque vulnerability in patients with coronary heart disease: An optical coherence tomography study

Background and aimsDietary intakes play important roles in the prevention and treatment of coronary heart disease (CHD). Coronary plaque vulnerability is the key mechanism leading to CHD progression. We aimed to explore the association between dietary intakes and plaque vulnerability via optical coherence tomography (OCT).Methods and resultsA total of 314 CHD patients were included in this study. Dietary intake status was assessed by semi-quantitative food frequency questionnaire and plaque vulnerability was measured by OCT. The results showed that vegetables were negatively associated with macrophage infiltration, thin cap fibroatheroma (TCFA) and thrombus [odds ratio (OR) = 0.48, 0.38, 0.38, 95% confidence interval (95% CI) = 0.24–0.93, 0.17–0.84, 0.15–0.94, all P < 0.05]; fruits were negatively associated with lipid plaque, TCFA, rupture and thrombus (OR = 0.17, 0.11, 0.12, 0.20, 95% CI = 0.07–0.39, 0.04–0.29, 0.05–0.28, 0.08–0.55, all P < 0.05); salt was positively associated with lipid plaque and TCFA (OR = 2.59, 2.83, 95% CI = 1.14–5.90, 1.23–6.51, all P < 0.05). Regarding nutrients intakes, dietary fiber was negatively associated with macrophage infiltration (OR = 0.34, 95% CI = 0.14–0.85, P = 0.021); folate was negatively associated with lipid plaque, TCFA and rupture (OR = 0.22, 0.16, 0.20, 95% CI = 0.09–0.58, 0.06–0.41, 0.08–0.51, all P < 0.05); vitamin C was negatively associated with TCFA, rupture and thrombus (OR = 0.26, 0.22, 0.05, 95% CI = 0.07–0.95, 0.07–0.65, 0.01–0.25, all P < 0.05); sodium was positively associated with lipid plaque, TCFA, rupture and thrombus (OR = 3.43, 3.96, 2.73, 4.84, 95% CI = 1.51–7.80, 1.66–9.45, 1.18–6.27, 1.76–9.28, all P < 0.05).ConclusionSalt and sodium were dietary risk factors for plaque vulnerability, whereas vegetables, fruits, dietary fiber, folate and vitamin C were dietary protective factors for plaque vulnerability.     

Comparison of COVID-19 pneumonia during the SARS-CoV-2 Omicron wave and the previous non-Omicron wave in a single facility

BackgroundThe characteristics of coronavirus disease 2019 (COVID-19) pneumonia caused by the severe acute respiratory syndrome coronavirus 2 Omicron variant have not been fully described. Unlike other variants, the Omicron variant replicates rapidly in the bronchus. Therefore, we hypothesized that it would have different computed tomography (CT) findings from non-Omicron variants.MethodsWe enrolled patients with COVID-19 who visited our hospital and underwent chest CT during the first month of the Omicron wave (January 2022; N = 231) and the previous non-Omicron wave (July 2021; N = 87). We retrospectively evaluated the differences in the prevalence rate and CT characteristics of COVID-19 pneumonia between the two waves.ResultsThe prevalence of pneumonia was significantly lower in the Omicron wave group (79/231, 34.2%) compared to the previous wave group (67/87, 77.0%) (P < 0.001). For the predominant distribution pattern of pneumonia, the Omicron wave group revealed a significantly lower rate of the peripheral pattern and a higher rate of the random pattern than the previous wave group. In addition, the Omicron wave group had a significantly lower rate of consolidation than the previous wave group. The ground-glass opacities (GGOs) rate was similar between the two wave groups. For GGOs patterns, cluster-like GGOs along the bronchi on chest CT were more frequently observed during the Omicron wave than during the previous wave.ConclusionThe Omicron wave group had a lower COVID-19 pneumonia prevalence than the previous wave group. Cluster-like GGOs should be noted as a characteristic CT finding of pneumonia during the Omicron wave.     

Pattern of liver function and clinical profile in COVID-19: A cross-sectional study of 91 patients

Background– COVID-19 caused by SARS-CoV-2 leads to myriad range of organ involvement including liver dysfunction.AimTo analyse the liver function in patients with COVID-19 and their association with respect to age, sex, severity of disease and clinical features.Materials and methodsThis study was a cross-sectional study done at Rajendra Institute of Medical Sciences, Ranchi. 91 patients admitted with confirmed SARS-CoV-2 infection were included in this study and divided into asymptomatic, mild, moderate and severe groups. Liver function tests were compared among different severity groups.ResultsOf 91 patients with COVID-19, 70 (76.9%) had abnormal liver function. Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total bilirubin levels was 1–2 × ULN in 33(36.3%), 34(37.3%), 12(13.2%), 6(6.6%) cases and >2 × ULN in 20(22%), 18(19.8%), 7(7.7%) and 2 (2.2%) cases respectively. Mean AST and ALP levels among different severity groups of COVID-19 was statistically significant (p < 0.05) whereas mean ALT and total bilirubin levels was statistically non-significant (p > 0.05). There was no statistical difference between males and females with regard to abnormal liver function. Liver injury was seen in 64.3% cases of hypertension and 73.3% cases of diabetes. Fever, myalgia, headache and breathlessness were found to be correlated significantly with severity of disease.ConclusionLiver injury is common in SARS-CoV-2 infection and is more prevalent in the severe disease group. Aspartate transaminase and alkaline phosphatase are better indicators of covid-19 induced liver injury than alanine transaminase and total bilirubin.     

Decrease in hemoglobin level predicts increased risk for severe respiratory failure in COVID-19 patients with pneumonia

BackgroundIn December 2019, the coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), emerged in Wuhan, China, and has since spread throughout the world. This study aimed to investigate the association between the change in laboratory markers during the three days after pneumonia diagnosis and severe respiratory failure in COVID-19 patients.MethodsData of 23 COVID-19 patients with pneumonia, admitted to the Kumamoto City Hospital between February and April 2020 were retrospectively analyzed.ResultsAmong the 23 patients, eight patients received mechanical ventilation (MV) (MV group), and the remaining 15 comprised the non-MV group. The levels of hemoglobin (Hb) and albumin (Alb) decreased in the MV group during the three days after pneumonia diagnosis more than in the non-MV group (median Hb: 1.40 vs. ?0.10 g/dL, P = 0.015; median Alb: 0.85 vs. ?0.30 g/dL, P = 0.020). Univariate logistic regression analysis showed that the decrease in Hb was associated with receiving MV care (odds ratio: 0.313, 95% confidence interval: 0.100–0.976, P = 0.045). Receiver operating characteristic curve analyses showed that the optimal cut-off value for the decrease in Hb level was ?1.25 g/dL, with sensitivity and specificity values of 0.867 and 0.750, respectively.ConclusionsThe decrease in Hb level during the short period after pneumonia diagnosis might be a predictor of worsening pneumonia in COVID-19 patients.     

Clopidogrel Monotherapy After 1-Month Dual Antiplatelet Therapy in Patients With Diabetes Undergoing Percutaneous Coronary Intervention

BackgroundDiabetes was reported to be associated with an impaired response to clopidogrel.ObjectivesThe aim of this study was to evaluate the safety and efficacy of clopidogrel monotherapy after very short dual antiplatelet therapy (DAPT) in patients with diabetes undergoing percutaneous coronary intervention (PCI).MethodsA subgroup analysis was conducted on the basis of diabetes in the STOPDAPT-2 (Short and Optimal Duration of Dual Antiplatelet Therapy After Everolimus-Eluting Cobalt-Chromium Stent–2) Total Cohort (N = 5,997) (STOPDAPT-2, n = 3,009; STOPDAPT-2 ACS [Short and Optimal Duration of Dual Antiplatelet Therapy After Everolimus-Eluting Cobalt-Chromium Stent–2 for the Patients With ACS], n = 2,988), which randomly compared 1-month DAPT followed by clopidogrel monotherapy with 12-month DAPT with aspirin and clopidogrel after cobalt-chromium everolimus-eluting stent implantation. The primary endpoint was a composite of cardiovascular (cardiovascular death, myocardial infarction, definite stent thrombosis, or stroke) or bleeding (TIMI [Thrombolysis In Myocardial Infarction] major or minor) endpoints at 1 year.ResultsThere were 2,030 patients with diabetes (33.8%) and 3967 patients without diabetes (66.2%). Regardless of diabetes, the risk of 1-month DAPT relative to 12-month DAPT was not significant for the primary endpoint (diabetes, 3.58% vs 4.12% [HR: 0.87; 95% CI: 0.56-1.37; P = 0.55]; nondiabetes, 2.46% vs 2.49% [HR: 0.99; 95% CI: 0.67-1.48; P = 0.97]; P_interaction = 0.67) and for the cardiovascular endpoint (diabetes, 3.28% vs 3.05% [HR: 1.10; 95% CI: 0.67-1.81; P = 0.70]; nondiabetes, 1.95% vs 1.43% [HR: 1.38; 95% CI: 0.85-2.25; P = 0.20]; P_interaction = 0.52), while it was lower for the bleeding endpoint (diabetes, 0.30% vs 1.50% [HR: 0.20; 95% CI: 0.06-0.68; P = 0.01]; nondiabetes, 0.61% vs 1.21% [HR: 0.51; 95% CI: 0.25-1.01; P = 0.054]; P_interaction = 0.19).ConclusionsClopidogrel monotherapy after 1-month DAPT compared with 12-month DAPT reduced major bleeding events without an increase in cardiovascular events regardless of diabetes, although the findings should be considered as hypothesis generating, especially in patients with acute coronary syndrome, because of the inconclusive result in the STOPDAPT-2 ACS trial.

Advanced glycation end products via skin autofluorescence as potential marker of carotid atherosclerosis in patients with type 2 diabetes

Background and aimsAdvanced glycation end products (AGEs) are reported to be correlated with diabetic vascular complications. This study aimed to investigate the association between AGEs and carotid atherosclerosis (CAS) as a surrogate marker of cardiovascular disease (CVD).Methods and resultsA total of 1006 patients with type 2 diabetes were included. CAS was defined as the presence of carotid arterial atherosclerotic plaque in any of bilateral carotid artery segments measured by ultrasonography. AGEs were measured by the noninvasive skin autofluorescence method. AGE_age index was calculated as AGEs × age/100. Patients with CAS showed a significantly higher AGE_age (P < 0.01), and the prevalence of CAS increased with ascending AGE_age levels (P for trend < 0.001). Logistic regression analysis revealed that AGE_age was significantly positively associated with odds of CAS, and the odds ratios of the presence of CAS across quartiles of AGE_age were 1.00, 3.00 [95% confidence interval (CI) 1.90–4.74], 4.04 (95%CI 2.50–6.53) and 4.99 (95%CI 2.97–8.40) for the multivariable-adjusted model (P for trend <0.001), respectively. In the fully adjusted model, each 5.0 increase in AGE_age was associated with a 0.019 mm increment in carotid intima-media thickness. Furthermore, AGE_age presented an acceptable predictive value for CAS, with an optimal cutoff point of 43.2, and the sensitivity, specificity and area under the curve (AUC) were 74.5% (95%CI 70.7–78.1%), 61.9% (95%CI 57.2–66.4%) and 0.735 (0.706–0.762), respectively.ConclusionAGE_age, the noninvasive measurement of AGEs combined with age is a promising approach for triaging patients at high risk of CVDs.     

Budesonide Oral Suspension Improves Outcomes in Patients With Eosinophilic Esophagitis: Results From a Phase 3 Trial

Background & AimsEosinophilic esophagitis (EoE) is a chronic, immune-mediated disease for which there is currently no pharmacologic therapy approved by the U.S. Food and Drug Administration.MethodsIn this double-blind, placebo-controlled, phase 3 trial, patients 11–55 years of age with EoE and dysphagia were randomized 2:1 to receive budesonide oral suspension (BOS) 2.0 mg twice daily or placebo for 12 weeks at academic or community care practices. Co-primary endpoints were the proportion of stringent histologic responders (≤6 eosinophils/high-power field) or dysphagia symptom responders (≥30% reduction in Dysphagia Symptom Questionnaire [DSQ] score) over 12 weeks. Changes in DSQ score (key secondary endpoint) and EoE Endoscopic Reference Score (EREFS) (secondary endpoint) from baseline to week 12, and safety parameters were examined.ResultsOverall, 318 patients (BOS, n = 213; placebo, n = 105) were randomized and received ≥1 dose of study treatment. More BOS-treated than placebo-treated patients achieved a stringent histologic response (53.5% vs 1.0%; Δ53% [95% confidence interval (CI), 43.8%–59.5%]; P < .001) or symptom response (52.6% vs 39.1%; Δ13% [95% CI, 1.6%–24.3%]; P = .024) over 12 weeks. BOS-treated patients also had greater improvements in least-squares mean DSQ scores and EREFS over 12 weeks than placebo-treated patients: DSQ, –13.0 (SEM 1.2) vs –9.1 (SEM 1.5) (Δ–3.9 [95% CI, –7.1 to –0.8]; P = .015); EREFS, –4.0 (SEM 0.3) vs –2.2 (SEM 0.4) (Δ–1.8 [95% CI, –2.6 to –1.1]; P < .001). BOS was well tolerated; most adverse events were mild or moderate in severity.ConclusionsIn patients with EoE, BOS 2.0 mg twice daily was superior to placebo in improving histologic, symptomatic, and endoscopic outcomes over 12 weeks. BOS 2.0 mg twice daily was well tolerated. ClinicalTrials.gov number: NCT02605837.     

Improved 3-Year Cardiac Survival After IVUS–Guided Long DES Implantation: A Patient-Level Analysis From 2 Randomized Trials

ObjectivesThe present study aimed to evaluate long-term cardiac survival benefit for intravascular ultrasound (IVUS)- versus angiography-guided long drug-eluting stent (DES) implantation.BackgroundAlthough the long-term benefit of IVUS guidance for DES implantation has been reported from recent randomized trials, this benefit was primarily driven by the reduction in repeat revascularization. Thus, it remains uncertain whether IVUS guidance improved survival during long-term follow-up.MethodsWe pooled the data of 2 randomized trials (IVUS-XPL [Impact of Intravascular Ultrasound Guidance on the Outcomes of Xience Prime Stents in Long Lesions] and ULTIMATE [Intravascular Ultrasound Guided Drug Eluting Stents Implantation in All-Comers Coronary Lesions]) and compared IVUS guidance versus angiography guidance in 2,577 patients with long lesions treated with an implanted stent length ≥28 mm. The primary end point was cardiac death at 3 years.ResultsA 3-year clinical follow-up was completed in 96%. The primary end point of cardiac death occurred in 12 patients (1.0%) in the IVUS-guided group vs 28 patients (2.2%) in the angiography-guided group (HR: 0.43; 95% CI: 0.22-0.84; P = 0.011). In addition, target lesion–related myocardial infarction occurred in 3 patients (0.2%) in the IVUS-guided group and in 9 patients (0.7%) in the angiography-guided group (HR: 0.33; 95% CI: 0.09-1.22; P = 0.081), stent thrombosis developed in 3 patients (0.2%) in the IVUS-guided group and 9 patients (0.7%) in the angiography-guided group (HR: 0.33; 95% CI: 0.09-1.23; P = 0.082), and ischemia-driven target lesion revascularization was observed in 47 patients (3.8%) in the IVUS-guided group and 80 patients (6.5%) in the angiography-guided group (HR: 0.57; 95% CI: 0.40-0.82; P = 0.002).ConclusionsIn this post hoc pooled patient-level analysis, the use of IVUS-guided long DES implantation compared with angiography-guided stent implantation improved long-term patient cardiac survival.     

Cambio en la enolasa neuroespecífica de los supervivientes de parada cardiorrespiratoria extrahospitalaria: herramienta útil para predecir el pronóstico neurológico

Introduction and objectivesNeuron-specific enolase (NSE) is a prognostic marker in out-of-hospital cardiopulmonary arrest (OHCA) survivors treated with mild therapeutic hypothermia (MTH). The objectives were to analyze the correlation between dynamic changes in NSE and outcomes and to determine the measurement timing that best predicts neurological status.MethodsMulticenter cohort study including patients admitted after shockable rhythm OHCA and treated with MTH. Serum NSE was sampled at 2 different times and Δ-NSE (%) was calculated as 100 x (NSE2-NSE1)/NSE1. In-hospital mortality and neurological outcome, as assessed by the Cerebral Performance Category (CPC) scale, were evaluated during admission and after a 6-month follow-up.ResultsWe included 166 patients admitted to 4 hospitals. In-hospital mortality was 31.9%. Almost 60% of patients had a good neurological recovery (CPC 1-2). On univariate and multivariate logistic regression analyses, an increase in NSE levels was associated with higher in-hospital mortality and worse CPC on discharge and after 6-months (P < .001). Positive Δ-NSE showed an OR = 9.28 (95% CI 4.40-19.57) for mortality, OR = 11.23 (95% CI 5.24-24.11) for CPC 3-5 at discharge and OR = 11.14 (95% CI 5.05-24.55) for CPC 3-5 after 6-months’ follow-up (P < .001). The first NSE measurement, conducted at 18 to 24 hours, and the second measurement at 69 to 77 hours after OHCA showed a high area under the curve in predicting CPC at discharge (0.9389 and 0.9909, respectively; 0.8096 for the whole cohort).ConclusionsDynamic changes in NSE serum levels are good markers of hard clinical outcomes after an OHCA due to shockable rhythm in an MTH-treated cohort. NSE measurements at specific intervals after OHCA may predict events even more precisely.     

Predictive model of persistent choledocholithiasis in patients with acute biliary pancreatitis

BackgroundCholedocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP.MethodsThis retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013–2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC.ResultsPatients underwent MRCP (n = 145, 71.1), MRCP and ERCP (n = 44, 21.56%), EUS and ERCP (n = 1, 0.49%), or ERCP (n = 14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p < 0.001; OR = 27; 95% CI: 5.8–185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72 h (p = 0.008; OR = 3.4; 95% CI: 1.5–8.9); and biliary sludge in the gallbladder (p = 0.008; OR = 0.03; 95% CI: 0.001–0.3).ConclusionsThe predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results.ConclusionsThe predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.     

Addition of fenofibrate to statins is associated with risk reduction of diabetic retinopathy progression in patients with type 2 diabetes and metabolic syndrome: A propensity-matched cohort study

AimThis study aimed to determine the association between fenofibrate added to statin therapy and diabetic retinopathy progression.MethodsIn this propensity-matched study using the Korean National Health Insurance Service cohort (2002–2019), patients with type 2 diabetes and metabolic syndrome (≥ 30 years) receiving statin therapy were matched 1:2 by propensity score into the statin plus fenofibrate group (n = 22,395) and statin-only group (n = 43,191). The primary outcome was a composite of diabetic retinopathy progression including vitreous hemorrhage, vitrectomy, laser photocoagulation, intravitreous injection therapy and retinal detachment.ResultsThe median (quartiles) follow-up duration was 44.0 (27.6–70.6) months. For the primary outcome, the incidence rate per 1,000 person-years was 9.66 in the statin-only group and 8.68 in the statin-plus-fenofibrate group. The risk of the primary outcome was significantly lower (hazard ratio [HR]=0.88; 95% confidence interval [0.81;0.96] P = 0.005) in the statin-plus-fenofibrate group than in the statin-only group. Only patients with pre-existing retinopathy showed benefits from fenofibrate treatment (HR=0.83 [0.73;0.95] P = 0.006). In addition, the statin plus fenofibrate group exhibited significantly lower risks of vitreous hemorrhage (HR= 0.86 [0.75;0.995] P = 0.042), laser photocoagulation (HR=0.86 [0.77;0.96] P = 0.009) and intravitreous injection therapy (HR=0.73 [0.59;0.90] P = 0.003) than those in the statin-only group. There was no significant interaction between the different characteristics at baseline and the treatment effect.ConclusionThe addition of fenofibrate to statins was associated with significantly lower risk of diabetic retinopathy progression than statin therapy alone in patients with type 2 diabetes and metabolic syndrome.     

10-Year All-Cause Mortality Following Percutaneous or Surgical Revascularization in Patients With Heavy Calcification

ObjectivesThe aim of this study was to assess 10-year all-cause mortality in patients with heavily calcified lesions (HCLs) undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).BackgroundLimited data are available on very long term outcomes in patients with HCLs according to the mode of revascularization.MethodsThis substudy of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study assessed 10-year all-cause mortality according to the presence of HCLs within lesions with >50% diameter stenosis and identified during the calculation of the anatomical SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score among 1,800 patients with the 3-vessel disease and/or left main disease randomized to PCI or CABG in the SYNTAX trial. Patients with HCLs were further stratified according to disease type (3-vessel disease or left main disease) and assigned treatment (PCI or CABG).ResultsThe 532 patients with ≥1 HCL had a higher crude mortality rate at 10 years than those without (36.4% vs 22.3%; HR: 1.79; 95% CI: 1.49-2.16; P < 0.001). After adjustment, an HCL remained an independent predictor of 10-year mortality (HR: 1.36; 95% CI: 1.09-1.69; P = 0.006). There was a significant interaction in mortality between treatment effect (PCI and CABG) and the presence or absence of HCLs (P_interaction = 0.005). In patients without HCLs, mortality was significantly higher after PCI than after CABG (26.0% vs 18.8%; HR: 1.44; 95% CI: 0.97-1.41; P = 0.003), whereas in those with HCLs, there was no significant difference (34.0% vs 39.0%; HR: 0.85; 95% CI: 0.64-1.13; P = 0.264).ConclusionsAt 10 years, the presence of an HCL was an independent predictor of mortality, with a similar prognosis following PCI or CABG. Whether HCLs require special consideration when deciding the mode of revascularization beyond their current contribution to the anatomical SYNTAX score deserves further evaluation.

No association between alcohol consumption and risk of atrial fibrillation: A two-sample Mendelian randomization study

Background and aimsAlthough many observational studies have suggested that alcohol intake was associated with incident atrial fibrillation (AF), controversy remains. This study aimed to examine the causal association of alcohol intake with the risk of AF.Methods and resultsTwo-sample Mendelian randomization (MR) analysis was performed to estimate the causal effects of alcohol consumption, alcohol dependence, or alcohol use disorder identification test (AUDIT) scores on AF. Summary data on single nucleotide polymorphisms (SNPs) associated with AF were obtained from a genome-wide association study (GWAS) with up to 1,030,836 participants. The fixed- and random-effect inverse-variance weighted (IVW) methods were used to calculate the overall causal effects. MR analysis revealed nonsignificant association of genetically predicted alcohol consumption with risk of AF using fixed- and random-effect IVW approaches (odds ratio (OR) [95% confidence interval (CI)] = 1.004 [0.796–1.266], P = 0.975; OR [95% CI] = 1.004 [0.766–1.315], P = 0.979). Genetically predicted alcohol dependence was also not causally associated with AF in the fixed- and random-effect IVW analyses (OR [95% CI] = 1.012 [0.978–1.048], P = 0.490; OR [95% CI] = 1.012 [0.991–1.034], P = 0.260). There was no significantly causal association between AUDIT and AF in the fixed- and random-effect IVW analyses (OR [95% CI] = 0.889 [0.433–1.822], P = 0.748; OR [95% CI] = 0.889 [0.309–2.555], P = 0.827). Sensitivity analyses indicated no evidence of pleiotropy and heterogeneity in statistical models.ConclusionsThis MR study did not find evidence of a causal association between alcohol intake and AF.     

Randomized Clinical Trial on Prevention of Radial Occlusion After Transradial Access Using Nitroglycerin: PATENS Trial

ObjectivesThe aim of this study was to evaluate whether administration of nitroglycerin at the beginning or end of a transradial approach (TRA) procedure would preserve radial patency.BackgroundThe TRA is becoming the preferred vascular access route in coronary interventions. Radial artery occlusion (RAO) is the most frequent complication. Routine vasodilator treatment aims to reduce spasm and possibly prevent RAO.MethodsThe authors designed a prospective, multicenter, randomized, double-blind, 2-by-2 factorial, placebo-controlled trial encompassing patients undergoing the TRA. Patients were randomized to either 500 μg nitroglycerin or placebo; each arm was also subrandomized to early (upon sheath insertion) or late (right before sheath removal) nitroglycerin administration to evaluate the superiority of nitroglycerin in the prevention of RAO with 24 hours on Doppler ultrasound.ResultsA total of 2,040 patients were enrolled. RAO occurred in 49 patients (2.4%). Fifteen of these patients (30.6%) showed re-establishment of flow at 30 days. Nitroglycerin, compared with placebo, did not reduce the risk for RAO at either of the 2 time points (early, 2.5% vs 2.3% [P = 0.66]; late, 2.3% vs 2.5% [P = 0.66]). By multivariable analysis, the presence of spasm (OR: 3.53; 95% CI: 1.87-6.65; P < 0.001) and access achieved with more than 1 puncture attempt (OR: 2.58; 95% CI: 1.43-4.66; P = 0.002) were independent predictors of RAO.ConclusionsThe routine use of nitroglycerin was not associated with a reduction in the rate of RAO, regardless of the time of administration (at the beginning or end of the TRA procedure).     

Predicted and Observed Mortality at 10 Years in Patients With Bifurcation Lesions in the SYNTAX Trial

BackgroundPercutaneous coronary intervention (PCI) of bifurcation lesions is associated with higher rates of adverse events, and currently it is unclear whether PCI or coronary artery bypass grafting (CABG) is the safer treatment for these patients at very long-term follow-up.ObjectivesThe aim of this study was to investigate the impact of bifurcation lesions on individual predicted and observed all-cause 10-year mortality in the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial.MethodsIn the SYNTAXES (SYNTAX Extended Survival) study, 10-year observed and individual predicted mortality derived from the SYNTAX score 2020 (SS-2020) was compared between patients with ≥1 bifurcation (n = 1,300) and those with no bifurcations (n = 487).ResultsAmong patients treated with PCI, patients with >1 bifurcation lesion compared with those without bifurcation lesions had a significantly higher risk for all-cause death (19.8% vs 30.1%; HR: 1.55; 95% CI: 1.12-2.14; P = 0.007), whereas following CABG, mortality was similar in patients with and those without bifurcation lesions (23.3% vs 23.0%; HR: 0.81; 95% CI: 0.59-1.12; P = 0.207; P_interaction = 0.006). In PCI patients, a 2-stent vs a 1-stent technique was associated with higher mortality (33.3% vs 25.9%; HR: 1.51; 95% CI: 1.06-2.14; P = 0.021). According to the SS-2020, among those with ≥1 bifurcation, there was equipoise for all-cause mortality between PCI and CABG in 2 quartiles of the population, whereas CABG was superior to PCI in the 2 remaining quartiles.ConclusionsBifurcation lesions require special attention from the heart team, considering the higher 10-year all-cause mortality associated with PCI. Careful evaluation of bifurcation lesion complexity and calculation of individualized 10-year prognosis using the SS-2020 may therefore be helpful in decision making.

Myocardial Injury on CMR in Patients With COVID-19 and Suspected Cardiac Involvement

BackgroundMyocardial injury in patients with COVID-19 and suspected cardiac involvement is not well understood.ObjectivesThe purpose of this study was to characterize myocardial injury in a multicenter cohort of patients with COVID-19 and suspected cardiac involvement referred for cardiac magnetic resonance (CMR).MethodsThis retrospective study consisted of 1,047 patients from 18 international sites with polymerase chain reaction–confirmed COVID-19 infection who underwent CMR. Myocardial injury was characterized as acute myocarditis, nonacute/nonischemic, acute ischemic, and nonacute/ischemic patterns on CMR.ResultsIn this cohort, 20.9% of patients had nonischemic injury patterns (acute myocarditis: 7.9%; nonacute/nonischemic: 13.0%), and 6.7% of patients had ischemic injury patterns (acute ischemic: 1.9%; nonacute/ischemic: 4.8%). In a univariate analysis, variables associated with acute myocarditis patterns included chest discomfort (OR: 2.00; 95% CI: 1.17-3.40, P = 0.01), abnormal electrocardiogram (ECG) (OR: 1.90; 95% CI: 1.12-3.23; P = 0.02), natriuretic peptide elevation (OR: 2.99; 95% CI: 1.60-5.58; P = 0.0006), and troponin elevation (OR: 4.21; 95% CI: 2.41-7.36; P < 0.0001). Variables associated with acute ischemic patterns included chest discomfort (OR: 3.14; 95% CI: 1.04-9.49; P = 0.04), abnormal ECG (OR: 4.06; 95% CI: 1.10-14.92; P = 0.04), known coronary disease (OR: 33.30; 95% CI: 4.04-274.53; P = 0.001), hospitalization (OR: 4.98; 95% CI: 1.55-16.05; P = 0.007), natriuretic peptide elevation (OR: 4.19; 95% CI: 1.30-13.51; P = 0.02), and troponin elevation (OR: 25.27; 95% CI: 5.55-115.03; P < 0.0001). In a multivariate analysis, troponin elevation was strongly associated with acute myocarditis patterns (OR: 4.98; 95% CI: 1.76-14.05; P = 0.003).ConclusionsIn this multicenter study of patients with COVID-19 with clinical suspicion for cardiac involvement referred for CMR, nonischemic and ischemic patterns were frequent when cardiac symptoms, ECG abnormalities, and cardiac biomarker elevations were present.     

High triglyceride-glucose index is associated with adverse cardiovascular outcomes in patients with acute myocardial infarction

Background and aimsTriglyceride glucose (TyG) index is considered a new surrogate marker of insulin resistance that associated with the development of vascular disease. The aim of this study was to evaluate the prognostic value of TyG index in patients with acute myocardial infarction (AMI).Methods and resultsA total of 3181 patients with AMI were included in the analysis. Patients were stratified into 2 groups according to their TyG index levels: the TyG index <8.88 group and the TyG index ≥8.88 group. The incidence of major adverse cardiovascular events (MACEs) during a median of 33.3-month follow-up were recorded. Multivariable Cox regression models revealed that the TyG index was positively associated with all-cause death [HR (95% CI): 1.51 (1.10,2.06), p = 0.010], cardiac death [HR (95% CI): 1.68 (1.19,2.38), p = 0.004], revascularization [HR (95% CI): 1.50 (1.16,1.94), p = 0.002], cardiac rehospitalization [HR (95% CI): 1.25 (1.05,1.49), p = 0.012], and composite MACEs [HR (95% CI): 1.19 (1.01,1.41), p = 0.046] in patients with AMI. The independent predictive effect of TyG index on composite MACEs was mainly reflected in the subgroups of male gender and smoker. The area under the curve (AUC) of the TyG index predicting the occurrence of MACEs in AMI patients was 0.602 [95% CI 0.580,0.623; p < 0.001].ConclusionHigh TyG index levels appeared to be associated with an increased risk of MACEs in patients with AMI. The TyG index might be a valid predictor of cardiovascular outcomes of patients with AMI.Trial registrationRetrospectively registered.     

Long-Term Outcomes of Patients With Elevated Mitral Valve Pressure Gradient After Mitral Valve Edge-to-Edge Repair

ObjectivesThe aim of this study was to investigate the adverse impact of elevated postprocedural mitral valve pressure gradient (MPG) on outcome in a real-world population of patients with severe mitral regurgitation (MR) who underwent transcatheter mitral valve edge-to-edge repair (TEER).BackgroundTEER has become a routine treatment alternative for patients with severe MR at high surgical risk. The consequences of elevated MPG after TEER have been subject to controversial debates.MethodsAll consecutive patients undergoing TEER for either severe degenerative MR (DMR) or functional MR (FMR) at a high-volume center between September 2008 and January 2020 were prospectively included and followed periodically. Postprocedural MPG by discharge transthoracic echocardiography was considered elevated at ≥5 mm Hg. The primary combined endpoint was death or heart failure rehospitalization after 5 years.ResultsA total of 713 patients undergoing TEER (DMR, n = 265; FMR, n = 445) were included. Elevated postprocedural MPG was present in 37.0% of those with DMR (n = 98) and 22.0% of those with FMR (n = 98). In contrast to patients with FMR, 6-minute walk distance did not improve in patients with DMR with elevated MPG. Kaplan-Meier analyses did not demonstrate significant differences for the primary endpoint in patients with DMR (low vs elevated MPG, 67.3% vs 74.4%; P = 0.06) and those with FMR (78.6% vs 74.8%; P = 0.54). After adjustment, elevated MPG was an independent predictor of the primary endpoint in patients with DMR (HR: 1.59; 95% CI: 1.03-2.45; P = 0.034) but not in those with FMR (HR: 0.87; 95% CI: 0.63-1.22; P = 0.43).ConclusionsElevated postprocedural MPG is an independent predictor of adverse clinical and functional outcomes in patients with DMR but not in those with FMR     

Índice cronotrópico y eventos adversos a largo plazo en insuficiencia cardiaca con fracción de eyección conservada

Introduction and objectivesLittle is known about the usefulness of heart rate (HR) response to exercise for risk stratification in heart failure with preserved ejection fraction (HFpEF). Therefore, this study aimed to assess the association between HR response to exercise and the risk of total episodes of worsening heart failure (WHF) in symptomatic stable patients with HFpEF.MethodsThis single-center study included 133 patients with HFpEF (NYHA II-III) who performed maximal cardiopulmonary exercise testing. HR response to exercise was evaluated using the chronotropic index (CI_x) formula. A negative binomial regression method was used.ResultsThe mean age of the sample was 73.2 ± 10.5 years; 56.4% were female, and 51.1% were in atrial fibrillation. The median for CI_x was 0.4 [0.3-0.55]. At a median follow-up of 2.4 [1.6-5.3] years, a total of 146 WHF events in 58 patients and 41 (30.8%) deaths were registered. In the whole sample, CI_x was not associated with adverse outcomes (death, P = .319, and WHF events, P = .573). However, we found a differential effect across electrocardiographic rhythms for WHF events (P for interaction = .002). CI_x was inversely and linearly associated with the risk of WHF events in patients with sinus rhythm and was positively and linearly associated with those with atrial fibrillation.ConclusionsIn patients with HFpEF, CI_x was differentially associated with the risk of total WHF events across rhythm status. Lower CI_x emerged as a risk factor for predicting higher risk in patients with sinus rhythm. In contrast, higher CI_x identified a higher risk in those with atrial fibrillation.
