: Aim To examine the choices Canadian family medicine residents make for oral anticoagulation (OAC) for patients with nonvalvular atrial fibrillation (AF). BACKGROUND: AF increases the risk of strokes. An important consideration in AF management is risk stratification for stroke and prescription of appropriate OAC. Family physicians provide the vast majority of OAC prescriptions. METHODS: We administered a survey to residents in multiple Canadian family medicine training programmes. Questions ex...

Purpose of the study To explore the oral anticoagulation (OAC) prescribing choices of Canadian internal medicine residents, at different training levels, in comparison with the Canadian Cardiovascular Society (CCS) guidelines for non-valvular atrial fibrillation (NVAF). Study design Cross-sectional, web-based survey, involving clinical scenarios designed to favour the use of non-vitamin K antagonists (NOACs) as per the 2014 CCS NVAF guidelines. Additional questions were also designed to determin...

Background The Length of stay, Acuity, Comorbidities, Emergency department visits in prior 6 months (LACE) index threshold of 10 predicts readmission or death in general medical patients in administrative databases. We assessed whether the unadjusted LACE index, computed at the bedside, can predict 30-day outcomes in patients hospitalized for heart failure. Methods We used logistic regression with LACE as the continuous predictor and 30-day readmissions and 30-day readmission or death as outcome...

Atrial fibrillation (AF) is a common cardiac arrhythmia and is associated with an increased risk of ischemic stroke. The aim of this study was to identify practice patterns of Canadian resident physicians pertaining to stroke prevention in nonvalvular AF according to the Canadian Cardiovascular Society guidelines. A Web-based survey consisting of 16 multiple-choice questions was distributed to 11 academic centres. Questions involved identification of risks of stroke, bleeding, and selection of a...

Background Low-flow low-gradient aortic stenosis (AS) is a predictor of worse outcome compared with normal-flow AS. Although depressed left ventricular ejection fraction (LVEF) is associated with low flow, there is less evidence to support the role of other indices of cardiac structure and function. Methods Clinical and echocardiographic data from patients with native AS and valve areas ≤ 1.0 cm 2 were retrospectively analyzed to identify characteristics that are associated with low-flow low-gra...

Background Heart failure (HF) is the commonest cause of hospitalization in older adults. Compared to routine hospitalization (RH), hospital at home (HaH)—substitutive hospital-level care in the patient’s home—improves outcomes and reduces costs in patients with general medical conditions. The efficacy of HaH in HF is unknown.

A 76-year-old male with a pacemaker presented with acute pulmonary oedema requiring invasive mechanical ventilation. Transthoracic echocardiography (TTE) revealed a partially flail anterior mitral leaflet, severe mitral regurgitation (MR), and pulmonary hypertension, not present on previous TTEs. Transoesophageal echocardiography (TEE) demonstrated an elongated anterior mitral valve leaflet (AMVL) with a flail A2 …

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia. It is associated with an increased risk of ischemic strokes. Stroke prevention is the mainstay of management. Novel oral anticoagulants (NOACs) are part of the current therapeutic arsenal and resident physicians should be familiar with their use. The aim of this study was to identify practice patterns of Canadian resident physicians with respect to stroke prevention in patients with nonvalvular AF. METHODS: This was a cr...

Background: Methanol is a common commercial compound that can lead to significant morbidity and mortality with high levels of exposure. The purpose of this study was to describe electrocardiographic (ECG) changes associated with methanol intoxication. Methods: A retrospective chart review was conducted with data from Kingston General Hospital collected between 2006 and 2011. Patient data, including demographics, medications, and laboratory data were recorded. Twelve-lead ECGs were obtained and c...
