BACKGROUND AND PURPOSE: Implementation of contextually appropriate, evidence-based, expert-recommended stroke prevention guideline is particularly important in Low-Income Countries (LMICs), which bear disproportional larger burden of stroke while possessing fewer resources. However, key quality characteristics of guidelines issued in LMICs compared with those in High-Income Countries (HICs) have not been systematically studied. We aimed to compare important features of stroke prevention guidelines issued in these groups...

As per the AHA 2015 and ERC 2015 guidelines for resuscitation, chest compression depth should be between 5 and 6 cm with a rate of 100-120 compressions per minute. Theoretical validation of these guidelines is still elusive. We developed a computer model of the cardiopulmonary resuscitation (CPR) system to validate these guidelines. A lumped element computer model of the cardiovascular system was developed to simulate cardiac arrest and CPR. Cardiac output was compared for a range of compression pressures and frequencies...

IMPORTANCE: Cardiovascular risk assessment is a fundamental component of prevention of cardiovascular disease (CVD). However, commonly used prediction models have been formulated in primarily or exclusively white populations. Whether risk assessment in black adults is dissimilar to that in white adults is uncertain. OBJECTIVES: To develop and validate risk prediction models for CVD incidence in black adults, incorporating standard risk factors, biomarkers, and subclinical disease...

In 2015, five trials demonstrated the efficacy of endovascular treatment for acute stroke, culminating in the revised American Heart Association/American Stroke Association (AHA/ASA) recommendations for stroke management. The different clinical scales used in these trials may be unfamiliar to emergency and on-call radiologists. The modified Rankin Scale was used to describe patient disability for prestroke assessment in three of the trials and for the 90-day follow up in all five trials. The Barthel index was used in one trial to score prestroke ability to perform activities of daily living...

The 2015 American Heart Association/American College of Cardiology/American Society of Hypertension Scientific Statement "Treatment of Hypertension in Patients with Coronary Artery Disease" is summarized in the context of a clinical case. The Statement deals with target blood pressures, and the optimal agents for the treatment of hypertension in patients with stable angina, in acute coronary syndromes, and in patients with ischemic heart failure. In all cases, the recommended blood pressure target is <140/90 mm Hg, but <130/80 mm Hg may be appropriate, especially in those with a history of a previous myocardial infarction or stroke, or at high risk for developing either...

BACKGROUND: A 1.5-day interactive forum was convened to discuss critical issues in the acquisition, analysis, and sharing of data in the field of cardiovascular and stroke science. The discussion will serve as the foundation for the American Heart Association's (AHA's) near-term and future strategies in the Big Data area. The concepts evolving from this forum may also inform other fields of medicine and science. METHODS AND RESULTS: A total of 47 participants representing stakeholders from 7 domains (patients, basic scientists, clinical investigators, population researchers, clinicians and healthcare system administrators, industry, and regulatory authorities) participated in the conference...

BACKGROUND: Randomised trials have reported higher stroke/death rates after carotid artery stenting (CAS) versus carotid endarterectomy (CEA). Despite this, the 2011 American Heart Association (AHA) guidelines expanded CAS indications, partly because of the Carotid Revascularization Endarterectomy versus Stenting Trial, but also because of improving outcomes in industry sponsored CAS Registries. The aim of this systematic review was: (i) to compare stroke/death rates after CAS/CEA in contemporary dataset registries, (ii) to examine whether published stroke/death rates after CAS fall within AHA thresholds, and, (iii) to see if there had been a decline (over time) in procedural risk after CAS/CEA...
