BACKGROUND: Although the association between coronary artery calcium (CAC) and future heart failure (HF) has been shown previously, the value of CAC progression in the prediction of HF has not been investigated. In this study, we investigated the association of CAC progression with subclinical left ventricular (LV) dysfunction and incident HF in the Multi-Ethnic Study of Atherosclerosis. METHODS AND RESULTS: The Multi-Ethnic Study of Atherosclerosis is a population-based study consisting of 6814 men and women aged 45 to 84, free of overt cardiovascular disease at enrollment, who were recruited from 4 ethnicities...

BACKGROUND: Non-obstructive coronary artery disease (CAD) on coronary angiography after myocardial infarction (MI) is associated with a lower risk of adverse outcomes, but the prognosis may not be benign. Our aim was to assess outcomes in MI with and without obstructive CAD, and in an age and sex matched comparison cohort without known cardiovascular disease. METHODS: We performed a single centre analysis of consecutive patients undergoing coronary angiography for MI between 2007 and 2012...

Background: The association between cholesterol ester transfer protein (CETP) Taq IB polymorphism and coronary artery disease (CAD) has been studied in different populations. Acute coronary syndrome (ACS) is a group of clinical symptoms within acute myocardial ischemia, including unstable angina (UA) and myocardial infarction (MI). Because there are no data reported in the literature concerning the cholesteryl ester transfer protein (CETP) Taq IB polymorphism in Egyptians, our study aimed to investigate the frequency of different CETP Taq IB genotypes in Egyptian patients with ACS and in healthy control individuals...

INTRODUCTION: Coronary artery disease is the leading cause of death worldwide. Although there are a number of algorithms in use for determining the risk of coronary artery disease and thus predicting future cardiovascular events, the data available regarding their validity among the Saudi population are insufficient. OBJECTIVE: We studied the validity of three clinical score systems in predicting a high risk population defined as having excessive coronary calcification: the American College of Cardiology/American Heart Association (ACC/AHA) Pooled Cohort Risk Equation, the Framingham Risk Score, and the European Systematic Coronary Risk Evaluation...

Background -Current strategies for cardiovascular disease (CVD) risk assessment among adults without known CVD are limited by suboptimal performance and a narrow focus on only atherosclerotic CVD (ASCVD). We hypothesized that a strategy combining promising biomarkers across multiple different testing modalities would improve global and atherosclerotic CVD risk assessment among individuals without known CVD. Methods -We included participants from the Multi-Ethnic Study of Atherosclerosis (MESA, n=6621) and Dallas Heart Study (DHS, n=2202) who were free from CVD and underwent measurement of left ventricular hypertrophy by electrocardiogram (ECG-LVH), coronary artery calcium (CAC), N-terminal pro B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT) and high-sensitivity C-reactive protein (hs-CRP)...

Air pollution is a worldwide contributor to cardiovascular disease mortality and morbidity. Traffic-related air pollution is a widespread environmental exposure and is associated with multiple cardiovascular outcomes such as coronary atherosclerosis, peripheral arterial disease, and myocardial infarction. Despite the recognition of the importance of both genetic and environmental exposures to the pathogenesis of cardiovascular disease, studies of how these two contributors operate jointly are rare. We performed a genome-wide interaction study (GWIS) to examine gene-traffic exposure interactions associated with coronary atherosclerosis...

Coronary artery disease (CAD) is a leading cause of mortality globally. However, the etiology and pathogenesis of CAD are not fully understood. The aim of the present meta-analysis was to estimate the association between the risk of CAD and Helicobacter pylori (H. pylori) infection. A literature search was performed to identify eligible studies published prior to August 14, 2014. Fixed or random effect meta-analytical methods were used to pool the data and perform the subgroup analyses. The effect measures estimated were the odds ratios (OR) for dichotomous data reported with 95% confidence intervals (95% CI)...

OBJECTIVES: This study sought to determine prognostic value of nonobstructive coronary artery disease (CAD) for atherosclerotic cardiovascular disease (ASCVD) events and to determine whether incorporation of this information into the pooled cohort equation reclassifies recommendations for statin therapy as defined by the 2013 guidelines for cholesterol management of the American College of Cardiology and American Heart Association (ACC/AHA). BACKGROUND: Detection of nonobstructive CAD by coronary computed tomography angiography may improve risk stratification and permit individualized and more appropriate allocation of statin therapy...

BACKGROUND: Few adults have ideal cardiovascular health (CVH). We studied associations of an overall CVH score with subclinical cardiovascular disease and events. We assessed whether associations varied by race/ethnicity. METHODS AND RESULTS: Among 5961 participants in the Multi-Ethnic Study of Atherosclerosis, components of CVH were measured at baseline, 2000-2002: systolic blood pressure, total cholesterol, fasting glucose, smoking, physical activity, diet, and body mass index...

BACKGROUND: Conventional coronary artery disease risk factors might potentially explain at least 90% of the attributable risk of coronary artery disease. To better understand the association between the pre-industrial lifestyle and low prevalence of coronary artery disease risk factors, we examined the Tsimane, a Bolivian population living a subsistence lifestyle of hunting, gathering, fishing, and farming with few cardiovascular risk factors, but high infectious inflammatory burden. METHODS: We did a cross-sectional cohort study including all individuals who self-identified as Tsimane and who were aged 40 years or older...

REVIEW
Negin Nezarat, Michael Kim, Matthew Budoff
A multitude of studies now support the understanding that an increased coronary artery calcium (CAC) score represents advanced atherosclerosis and high risk for cardiovascular disease (CVD) and, as such, should be treated with conventional therapies for those considered high risk. Data is now available to guide treatment with aspirin, statins, and lifestyle management. The new ACC/AHA 2013 guidelines support intensifying statin therapy when the CAC is ≥75th percentile for age, sex, and ethnicity/race or when the calcium score is ≥300 Agatston units...

BACKGROUND: Genetic predisposition to the clinical categories of coronary artery disease (anatomical viz., insignificant, single, double, and triple vessel diseases and phenotypic severity categories viz., angina, acute coronary syndrome, and myocardial infarction) is poorly understood. Particularly, the apolipoprotein genes clustered at 11q23.3 chromosomal region play a vital role in cholesterol homeostasis, and a large number of SNPs identified in this region need to be explored for their association with the clinical categories of CAD...

BACKGROUND: Coronary artery calcium (CAC) predicts coronary heart disease (CHD) events better than carotid wall plaque presence; however, differences in the utility of CAC burden and carotid plaque burden across the spectrum of cardiovascular disease (CVD) events is unknown. METHODS AND RESULTS: CVD, CHD and stroke/transient ischemic attack (TIA) events were evaluated prospectively in a multiethnic cohort without CVD at baseline. Carotid plaque score was determined by the number of ultrasound-detected plaques in the common, bifurcation, and internal carotid artery segments...

INTRODUCTION: In cross-sectional survey studies, obese Latinos are less likely to be screened for elevated serum cholesterol, despite their higher risk for hyperlipidemia and coronary artery disease. This study evaluated insurance and racial/ethnic disparities in lipid screening receipt between obese Latino and non-Hispanic white patients in Oregon community health centers (CHCs) over 5 years, using electronic health record data. METHODS: This retrospective cohort study evaluated obese (BMI ≥30), low-income, adult patients (aged 21-79 years) with at least one visit at an Oregon CHC during 2009-2013 (n=11,095)...
