BACKGROUND: Myocardial injury has been described in coronavirus-2019 (COVID-19). Few studies have reported cardiovascular imaging data with transthoracic echocardiography (TTE) and electrocardiography (ECG) findings in COVID-19 patients, and their correlation with mortality. METHODS: We conducted a retrospective cohort study that included COVID-19 patients from March 2020 through February 2021 who had TTE and ECG during hospital admission. Myocardial injury was defined by an elevated high-sensitivity troponin T level > 20 ng/L...

BACKGROUND: There is limited literature guiding the prescribing of direct oral anticoagulants (DOACs) early after cardiac surgery as this population has been excluded from landmark randomized controlled trials. This study aims to determine the rate of in-hospital DOAC use compared with warfarin early after cardiac surgery, evaluate factors associated with DOAC use, determine difference in postoperative length of stay, and characterize bleeding events. METHODS: A retrospective cohort study was conducted in adult patients with indications for anticoagulation and receiving either a DOAC or warfarin after cardiac surgery during their index hospitalization...

Because of the COVID-19 pandemic, several health care services, including cardiac rehabilitation (CR), had to transition to virtual delivery, for which formal evaluations are lacking. In this pilot study, we investigated the implementation of a virtual CR program by surveying 30 patients attending virtual CR. Virtual CR was well received, although patients provided recommendations to improve delivery such as offering individual sessions and changing how education materials were delivered. Virtual delivery of CR likely has a role in health care, either independently or as part of a hybrid model; however, further evaluation is required...

BACKGROUND: Impairment of the conduction system is a common complication of transcatheter aortic valve replacement (TAVR), which is typically performed in elderly patients. A leadless pacemaker (LP) may be a suitable option in this frail population, but the available scientific data concerning the efficacy and safety of leadless pacing after TAVR are sparse. The purpose of this analysis was to evaluate the efficacy and safety of LP implantation in patients with relevant bradycardias after TAVR, compared to other indications...

BACKGROUND: High-grade atrioventricular block (HGAVB) is common after transcatheter aortic valve implantation (TAVI), often necessitating permanent pacemaker (PPM) implantation. Delayed HGAVB has varying definitions but typically refers to onset 48 hours after TAVI or following discharge and may cause syncope and sudden cardiac death. This review estimates the incidence of delayed HGAVB and identifies limitations of current literature. METHODS: A systematic review was performed of the following online databases: Medline, Cochrane, Web of Science, and Scopus...

BACKGROUND: People living with frailty are vulnerable to poor outcomes and incur higher health care costs after coronary artery bypass graft (CABG) surgery. Frailty-defining instruments for population-level research in the CABG setting have not been established. The objectives of the study were to develop a preoperative frailty index for CABG (pFI-C) surgery using Ontario administrative data; assess pFI-C suitability in predicting clinical and economic outcomes; and compare pFI-C predictive capabilities with other indices...

Information is evolving on the safety of same-day discharge (SDD) after left atrial appendage occlusion (LAAO) procedures. This single-centre retrospective study evaluated the feasibility of SDD and reported on the 30-day rehospitalization rate in patients discharged same-day compared with those admitted overnight after LAAO. Key findings of this study included more than 85% of patients with LAAO were safely discharged same-day; the rate of postdischarge rehospitalization was similar in SDD patients and those admitted overnight; and approximately 1 in 10 patients who had LAAO procedures were rehospitalized within 30 days postprocedure...

BACKGROUND: Endocardial catheter ablation for ventricular tachycardia (VT) may fail because of the inability to deliver transmural lesions. Ultra-low-temperature cryoablation (ULTC) uses near-critical nitrogen and can generate temperatures as low as -196 °C. We report a series of 18 patients who underwent ULTC at the McGill University Health Centre (MUHC), representing the largest single-centre experience to date. METHODS: Eighteen patients with monomorphic drug-refractory VT underwent VT ablation with ULTC at our institution as part of the first-in-human CryoCure-VT trial (NCT04893317)...

This cross-sectional study evaluated the impact of patient involvement in care (PIC) on psychosocial outcomes and health-related quality of life (HRQoL) in patients with hypertrophic cardiomyopathy (HCM) (n = 34). Patients with low-to-moderate PIC were older than those with high PIC (66.8 years vs 57.3 years; P  = 0.04). PIC was negatively correlated with depressive symptoms ( r  = -0.39; P  = 0.02) and positively correlated with heart-focused attention ( r  = 0.39; P  = 0.02)...

BACKGROUND: To facilitate the shift from risk-factor management to primordial prevention of cardiovascular disease, the American Heart Association developed guidelines to score and track cardiovascular health (CVH). How the prevalence and trajectories of a high level of CVH across the life course compare among high- and lower-income countries is unknown. METHODS: Nationally representative survey data with CVH variables (physical activity, cigarette smoking, body mass index, blood pressure, blood glucose, and total cholesterol levels) were identified in Ethiopia, Bangladesh, Brazil, England, and the US for adults (aged 18-69 years and not pregnant)...

BACKGROUND: The study assessed the outcomes of patients undergoing percutaneous coronary intervention (PCI) to bypass grafts, focusing on all-cause mortality and target vessel failure (TVF) rates. METHODS: A single-centre registry analysis included 364 patients who underwent PCI on coronary bypass grafts between 2008 and 2019. The study analyzed all-cause mortality and TVF, which encompassed target lesion revascularization, target vessel revascularization, and medically treated occluded target graft post-PCI...

Lipoprotein(a) (Lp[a]) is an low-density lipoprotein (LDL)-like particle in which apolipoprotein (apo) B is covalently bound to a plasminogen-like molecule called apo(a). A High level of Lp(a) has been demonstrated to be an independent, causal, and prevalent risk factor for atherosclerotic cardiovascular disease (ASCVD), as well as aortic valve disease, through mechanisms that promote atherogenesis, inflammation, and thrombosis. With reliable and accessible assays, Lp(a) level has been established to be associated linearly with the risk for ASCVD...
