BACKGROUND: Heart failure (HF) clinics (HFCs) are an integral aspect of the strategy for community HF care. METHODS: A systematic search was conducted to retrieve studies. We searched for candidate articles in the PubMed, EMBASE, and Cochrane databases from 1990 to January 2017. RESULTS: We included 16 randomized controlled trials in the meta-analysis with 3999 patients. The HFC group had a lower incidence of the primary composite end point of HF hospitalization and all-cause mortality (odds ratio [OR], 0...

BACKGROUND: There are several forms of calcium deposition, which play different roles in the stability of the coronary artery. It remains unknown whether certain calcification morphological characteristics determine rupture of lipid-rich lesions in the same plaque in acute coronary syndrome (ACS). METHODS: We retrospectively analyzed 550 patients with ACS between May 2008 and October 2014, who had undergone preintervention optical coherence tomography (OCT) imaging examination...

This companion article is intended to address common clinical scenarios in patients with implantable defibrillators that were not addressed in the 2016 Canadian Cardiovascular Society/Canadian Heart Rhythm Society implantable cardioverter defibrillator guidelines including recommendations for device programming to improve detection, to minimize shocks (appropriate and inappropriate), and to minimize ventricular pacing. Important issues at the time of replacement such as device prescription, technical aspects (vascular access, extraction), and management of components on advisories are also discussed...

In this article we compare and contrast the current recommendations, and highlight the important differences, in the American College of Cardiology/American Heart Association/Heart Rhythm Society, European Society of Cardiology, and Canadian Cardiovascular Society atrial fibrillation (AF) guidelines. Although many of the recommendations of the various societies are similar, there are important differences in the methodologies underlying their development and the specific content. Specifically, key differences can be observed in: (1) the definition of nonvalvular AF, which subsequently affects anticoagulation choices and candidacy for non-vitamin K antagonist oral anticoagulants; (2) the symptom score used to guide management decisions and longitudinal patient profiling; (3) the stroke risk stratification algorithm used to determine indications for oral anticoagulant therapy; (4) the role of acetylsalicylic acid in stroke prevention in AF; (5) the antithrombotic regimens used in the context of coronary artery disease, acute coronary syndromes, and percutaneous coronary intervention; (6) the rate control target and medications recommended to achieve the target; and (7) the role of "first-line" catheter ablation, open surgical ablation, and left atrial appendage exclusion...

Mihaela Calcaianu, Didier Bresson, Jacques Lévy
In this article we describe, to our knowledge, the first case of a potentially lethal dysfunction of a subcutaneous implantable cardioverter-defibrillator (S-ICD). A 70-year-old patient underwent primary S-ICD implantation. Nine months after, communication could not be established with the device. Chest radiography revealed that the lead had moved and wrapped around the generator. After equipment extraction, we observed the lead wound around the sagittal axis of the generator. A burn mark with melted metal was found inside the generator...

Subcutaneous implantable cardioverter defibrillators (S-ICDs) provide effective defibrillation, while also reducing the risk of long-term lead problems. However, S-ICDs do not offer bradycardia or antitachycardia pacing and therefore use has been limited. Combined implantation of an S-ICD with a leadless pacemaker (LP) has been proposed to overcome this limitation. Although a handful of combined S-ICD/LP implantations have been reported for Nanostim (St Jude Medical, St Paul, MN) as well as Micra LP (Medtronic, Minneapolis, MN) systems, none have documented delivery of appropriate shock therapies for spontaneous ventricular tachycardia...

A persistent left superior vena cava (SVC) results from failed obliteration of the left common cardinal vein during embryogenesis, with a spectrum of anatomic variants. We report a rare case of bilateral SVCs connected by a bridging vein and with a direct left SVC connection to the left atrial appendage in an asymptomatic patient without hypoxemia or associated congenital heart disease on transthoracic echocardiography, computed tomography, and magnetic resonance imaging. A multimodality imaging approach is valuable to search for associated anomalies and to confirm this anatomic variant, which has important implications on vascular procedures and avoidance of systemic embolism...

BACKGROUND: Health administrative data are frequently used for hypertension surveillance. The aim of this systematic review was to determine the sensitivity and specificity of the commonly used hypertension case definition of 2 physician outpatient claims within a 2-year period or 1 hospital discharge abstract record. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched MEDLINE (from 1946) and EMBASE (from 1947) for relevant studies through September 2016 (keywords: "hypertension," "administrative databases," "validation studies")...

BACKGROUND: Plasma angiopoietin-like 2 (Angptl2), a proinflammatory protein, has been associated with obesity and diabetes. Whether weight loss induced by bariatric surgery and associated improvement of the cardiometabolic risk profile influence circulating Angptl2 levels is unknown. We tested whether biliopancreatic diversion with duodenal switch (BPD-DS) surgery alters plasma Angptl2 concentrations. METHODS: Severely obese patients (n = 73; body mass index: 49...

BACKGROUND: Direct-acting oral anticoagulants (DOACs) are widely prescribed for stroke prevention in patients with atrial fibrillation (AF). An important advantage of DOACs is that routine monitoring of an anticoagulation response is not necessary. Nevertheless, because of their mechanism of action, a DOAC anticoagulation effect can be inferred based on the observed plasma concentration. However, there is a paucity of data relating to observed interpatient variation in DOAC plasma concentrations in the postmarket clinical setting...

BACKGROUND: Long-term aspirin prevents vascular events but is only modestly effective. Rivaroxaban alone or in combination with aspirin might be more effective than aspirin alone for vascular prevention in patients with stable coronary artery disease (CAD) or peripheral artery disease (PAD). Rivaroxaban as well as aspirin increase upper gastrointestinal (GI) bleeding and this might be prevented by proton pump inhibitor therapy. METHODS: Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) is a double-blind superiority trial comparing rivaroxaban 2...

BACKGROUND: Frailty is a risk factor for mortality, morbidity, and prolonged length of stay after cardiac surgery, all of which are major drivers of hospitalization costs. The incremental hospitalization costs incurred in frail patients have yet to be elucidated. METHODS: Patients aged ≥ 60 years were evaluated for frailty before coronary artery bypass grafting or heart valve surgery at 2 academic centres between 2013 and 2015 as part of the McGill Frailty Registry...

BACKGROUND: Childhood adversity increases the risk for cardiovascular disease (CVD) in adulthood. Previously proposed mechanisms suggest that the association is mediated by stress reactivity-known to be higher in women-and is aggravated by adult stress, but this has not yet been confirmed. Therefore, we investigated sex differences to better understand possible pathways from childhood adversity to CVD. METHODS: The National Population Health Survey, a 15-year cohort study of Canadians aged 18-49 years at baseline was used...

BACKGROUND: Bleeding complications accompanying coronary revascularization are associated with increased mortality; however, few data are available on subsequent bleeding risk. We used administrative data to assess the incidence of late bleeding events in patients with acute coronary syndrome (ACS) according to treatment allocation. METHODS: The cohort and bleeding events were identified through the Canadian Institute for Health Information discharge abstract database...
