Clinicians use branch pulmonary artery (BPA) blood flow distribution to help determine the need for intervention. Although phase-contrast magnetic resonance (PCMR) flow measurements are accurate, this has never been shown…
Genes associated with hypertrophic cardiomyopathy (HC) are not uniformly expressed in the atrial myocardium. Whether this may impact susceptibility to atrial fibrillation (AF) is unresolved. To analyze the prevalence and…
Serum osmolality may fluctuate with neurohormonal activation and in response to certain therapeutics in patients with heart failure (HF). The clinical relevance of osmolality in patients with HF has not…
The impact of physical inactivity on heart failure (HF) mortality is unclear. We analyzed data from the HF Adherence and Retention Trial (HART) which enrolled 902 patients with New York…
Reintroduction of amiodarone in patients with a history of amiodarone-induced thyrotoxicosis (AIT) is rarely used. To date, the risk of AIT recurrence after amiodarone reintroduction is unpredicted. The aim of…
Left atrial appendage closure with the WATCHMAN device is an alternative to anticoagulation for stroke prevention in selected patients with atrial fibrillation (AF). LA device-related thrombus (DRT) is poorly defined…
This national chart audit of 7,019 patients with nonvalvular atrial fibrillation (AF) from 735 primary care physician practices sought to examine the management of Canadian patients with AF through an…
Although prices for medical services are known to vary markedly between hospitals, it remains unknown whether variation in hospital prices is explained by differences in hospital quality or reimbursement from…
Obesity has been identified as a risk factor for postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG). However, no studies have addressed the influence of race on this…
Diabetes mellitus confers the highest mortality risk in primary and secondary cardiovascular prevention, but long-term prognosis differences between different forms of cardiovascular disease have not been assessed. We hypothesized that…
