BACKGROUND: Clopidogrel is one of the most commonly prescribed medications because of its ability to improve clinical outcomes for a broad range of cardiovascular conditions. After patent protection expired for Plavix in 2012, many healthcare systems adopted generic clopidogrel as a strategy to reduce healthcare costs. METHODS AND RESULTS: We conducted a population-based observational study to determine whether generic clopidogrel was noninferior to Plavix. Patients who were hospitalized with an acute coronary syndrome (ACS) from 2009 to 2014 in Ontario, Canada, >65 years, survived ≥7 days after discharge, were eligible for inclusion...

Population wellbeing, an aggregate measure of positive mental, physical, and emotional health, has previously been used as a marker of community thriving. We examined whether several community measures of wellbeing, and their change since 2012, could be used to understand electoral changes that led to the outcome of the 2016 United States presidential election. We found that areas of the US which had the largest shifts away from the incumbent party had both lower wellbeing and greater drops in wellbeing when compared with areas that did not shift...

Background: Although the peer review process is believed to ensure scientific rigor, enhance research quality, and improve manuscript clarity, many investigators are concerned that the process is too slow, too expensive, too unreliable, and too static. In this feasibility study, we sought to survey corresponding authors of recently published clinical research studies on the speed and efficiency of the publication process. Methods: Web-based survey of corresponding authors of a 20% random sample of clinical research studies in MEDLINE-indexed journals with Ovid MEDLINE entry dates between December 1 and 15, 2016...

BACKGROUND: Many young investigators are interested in cardiovascular (CV) outcomes research; however, the current training experience of early investigators across the United States is uncertain. METHODS: From April to November 2014, we surveyed mentees and mentors of early-stage CV outcomes investigators across the United States. We contacted successful grantees of government agencies, members of professional organizations, and trainees in CV outcomes training programs...

BACKGROUND: Outcomes research training programs should prepare trainees to successfully compete for research funding. We examined how early-career investigators' prior and desired training aligns with recently funded cardiovascular (CV) outcomes research. METHODS: We (1) reviewed literature to identify 13 core competency areas in CV outcomes research; (2) surveyed early-career investigators to understand their prior and desired training in each competency area; (3) examined recently funded grants commonly pursued by early-career outcomes researchers to ascertain available funding in competency areas; and (4) analyzed alignment between investigator training and funded research in each competency area...

BACKGROUND: The reasons for China's high stroke prevalence are not well understood. The cardiovascular risk factor profiles of China and the United States have not been directly compared in nationally representative population samples. METHODS AND RESULTS: Using data from the CHARLS (China Health and Retirement Longitudinal Study) and the NHANES (US National Health and Nutrition Examination Survey), we compared cardiovascular risk factors from 2011 to 2012 among people aged 45 to 75 years between the 2 countries (China, 12 654 people; United States, 2607 people): blood pressure, cholesterol, body mass index, waist circumference, fasting plasma glucose, hemoglobin A1c, and high-sensitivity C-reactive protein...

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a preventable cause of in-hospital death, and one of the most prevalent vascular diseases. There is a lack of knowledge with regards to contemporary presentation, management and outcomes of patients with VTE. Many clinically important subgroups (including the elderly, those with recent bleeding and pregnant patients) have been under-represented in clinical trials. Furthermore, design of clinical trials is challenging in some scenarios, such as in those with hemodynamically unstable PE...

INTRODUCTION: Mobile health interventions have the potential to promote risk factor management and lifestyle modification, and are a particularly attractive approach for scaling across healthcare systems with limited resources. We are conducting two randomised trials to evaluate the efficacy of text message-based health messages in improving secondary coronary heart disease (CHD) prevention among patients with or without diabetes. METHODS AND ANALYSIS: The Cardiovascular Health And Text Messaging (CHAT) Study and the CHAT-Diabetes Mellitus (CHAT-DM) Study are multicentre, single-blind, randomised controlled trials of text messaging versus standard treatment with 6 months of follow-up conducted in 37 hospitals throughout 17 provinces in China...
