31 mm/mm Hg). Patients with RV-PA uncoupling presented more frequently with heart failure symptoms had larger RV and left ventricular dimensions, and more severe TR compared to those with RV-PA coupling. During a median follow-up of 51 (IQR, 17 to 86) months, 586 patients (51%) died. The cumulative 5-year survival rate was lower in patients with RV-PA uncoupling compared to their counterparts (37% vs 64%, p less then 0.001). After correcting for potential confounders, RV-PA uncoupling was the only echocardiographic parameter independently associated with all-cause mortality (HR 1.462; 95% CI 1.192 to 1.793; p less then 0.001). In conclusion, RV-PA uncoupling in patients with secondary TR is independently associated with poor prognosis and may improve risk stratification.The ECG findings during sudden collapse (syncope or sudden death) in severe aortic stenosis (AS) are not well defined. We conducted a comprehensive review of the literature for ECG data during sudden collapse in patients with AS and provided a case report of our own. There were 37 published cases of syncope or sudden death in patients with severe AS which were documented by ECG. Brady- or ventricular arrhythmias were documented in 34 cases (92%). Bradyarrhythmia (n = 24; 71%) was more common at the time of collapse than ventricular tachyarrhythmia (n = 10; 29%). There was slowing of the sinus rate before bradyarrhythmia in the vast majority of patients with bradyarrhythmia but not in those presenting with ventricular tachyarrhythmia (75% vs 0%; p less then 0.001).  https://www.selleckchem.com/products/nf-kb-activator-1.html  ECG evidence of ischemia (ST-segment depression or elevation) was present in most patients with bradyarrhythmia but not in those with ventricular tachyarrhythmia (75% vs 0%; p = 0.011). In conclusion, our findings suggest that left ventricular baroreceptor activation plays a dominant role in the pathophysiology of sudden collapse in patients with severe AS and suggest that ischemia may play a role as well.Aspirin remains the gold standard antiplatelet regimen following coronary artery bypass grafting (CABG), however, there is growing support for dual antiplatelet therapy (DAPT). This study compares outcomes of aspirin monotherapy versus DAPT following CABG. This was a propensity-matched retrospective study from a large, multi-hospital healthcare system. It included patients who received either aspirin monotherapy or DAPT following isolated CABG between 2011 and 2018. Patients prescribed aspirin monotherapy were started on 81 mg aspirin daily, and patients on DAPT were prescribed 81 mg aspirin daily and 75 mg clopidogrel daily. Patients received alternative drug dosing or antiplatelet agents other than clopidogrel only if this was prescribed for another diagnosis or they had a preexisting contraindication. Primary outcomes included overall survival and major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of death, myocardial infarction, stroke, or repeat revascularization. Kaplan-Meiwas associated with a higher postoperative transfusion rate.Increased carotid intima-media thickness (cIMT) is associated with heart failure (HF) in previous studies, but it is not known whether the association of cIMT differs between HF with reduced (HFrEF) versus preserved ejection fraction (HFpEF). We studied 6699 participants (mean age 62 ± 10 years, 47% male, and 38% white) from the Multi-Ethnic Study of Atherosclerosis (MESA) with baseline cIMT measurements. We classified HF events as HFrEF (EF less then 50%) or HFpEF (EF ≥ 50%) at the time of diagnosis. Cox proportional hazard regression was used to compute hazard ratios (HR), and 95% confidence intervals (CI) for the association between the IMT Z-score (measured maximum IMT of Internal Carotid (IC) and Common Carotid (CC) sites as the mean of the maximum IMT of the near and far walls of right and left sides), and incident HFrEF or HFpEF. Models were adjusted for covariates and interim coronary artery disease (CAD) events. A total of 191 HFrEF and 167 HFpEF events occurred during follow-up. In multivariable analysis, each 1 standard deviation increase in the measured maximum IMT (Z-score) was associated with both HFrEF and HFpEF in the unadjusted and demographically adjusted models [HR, 95% CI 1.57 (1.43 to 1.73)] and [HR, 95% CI 1.61 (1.47 to 1.77)] but not in the fully adjusted models [HR, 95% CI 1.11 (0.96 to 1.28)] and [HR, 95% CI 1.13 (0.98 to 1.30)]. In conclusion, cIMT was significantly associated with incident HF, but the association is partially attenuated with adjustment for demographic factors and becomes non-significant after adjustment for other traditional heart failure risk factors and interim CAD events. There was no difference in the association of IMT measures with HFrEF versus HFpEF.Thoracic aortic calcium(TAC) is an important marker of extracoronary atherosclerosis with established predictive value for all-cause mortality. We sought to explore the predictive value of TAC for stroke mortality, independent of the more established coronary artery calcium (CAC) score. The CAC Consortium is a retrospectively assembled database of 66,636 patients aged ≥18 years with no previous history of cardiovascular disease, baseline CAC scans for risk stratification, and follow-up for 12 ± 4 years. CAC scans capture the adjacent thoracic aorta, enabling assessment of TAC from the same images. TAC was available in 41,066 (62%), and was primarily analyzed as present or not present. To account for competing risks for nonstroke death, we utilized multivariable-adjusted Fine and Gray competing risk regression models adjusted for traditional cardiovascular risk factors and CAC score. The mean age of participants was 53.8 ± 10.3 years, with 34.4% female. There were 110 stroke deaths during follow-up. The unadjusted subdistribution hazard ratio (SHR) for stroke mortality in those who had TAC present compared with those who did not was 8.80 (95% confidence interval [CI] 5.97, 12.98). After adjusting for traditional risk factors and CAC score, the SHR was 2.21 (95% CI1.39,3.49). In sex-stratified analyses, the fully adjusted SHR for females was 3.42 (95% CI 1.74, 6.73) while for males it was 1.55 (95% CI 0.83, 2.90). TAC was associated with stroke mortality independent of CAC and traditional risk factors, more so in women. The presence of TAC appears to be an independent risk marker for stroke mortality.
