The association of the CYP2J2 G-50T polymorphism with coronary artery disease has been explored, but the results remain controversial. Thus, a meta-analysis was conducted to provide a comprehensive estimate of this association. We selected ten articles encompassing 12 independent case-control studies with 7063 cases and 10,453 controls for this meta-analysis. Overall, we found significant associations between the CYP2J2 G-50T polymorphism and coronary artery disease risk in three genetic models (allele model: odds ratio (OR) = 1...

BACKGROUND: Residual atherosclerotic cardiovascular disease (ASCVD) risk in statin-treated US adults without known ASCVD is not well described. OBJECTIVE: To quantitate residual ASCVD risk and its predictors in statin-treated adults. METHODS: We studied 1014 statin-treated adults (53.3% female, mean 66.0 years) free of clinical ASCVD in the Multi-Ethnic Study of Atherosclerosis. We examined ASCVD event rates by National Lipid Association risk groups over 11-year follow-up and the relation of standard risk factors, biomarkers, and subclinical atherosclerosis measures with residual ASCVD event risk...

The placenta has generated many beliefs over centuries and in all ethnicities. Considered in our society as a surgical waste, it is elsewhere contemplated for its mysterious protective powers, viewed as the seat of the soul, disposed of, burnt or even buried. However, once time is taken for its examination, the placenta tells a story. Of interest is the similarity observed between placental vascular disease in hypertensive pregnancy and atherosclerosis in coronary artery disease for example. Hypertension in pregnancy is frequent and associated with increased adverse obstetrical outcomes, and long-term risk of cardiovascular and kidney disease...

OBJECTIVES: This study sought to determine whether coronary artery calcium (CAC) could be used to optimize statin allocation among individuals for whom trial-based evidence supports efficacy of statin therapy. BACKGROUND: Recently, allocation of statins was proposed for primary prevention of atherosclerotic cardiovascular disease (ASCVD) based on proven efficacy from randomized controlled trials (RCTs) of statin therapy, a so-called trial-based approach. METHODS: The study used data from MESA (Multi-Ethnic Study of Atherosclerosis) with 5,600 men and women, 45 to 84 years of age, and free of clinical ASCVD, lipid-lowering therapy, or missing information for risk factors at baseline examination...

Nitric oxide is an important antiatherosclerotic agent. The main determinant of nitric oxide levels is enzyme nitric oxide synthase encoded by the NOS3 gene, the common variants in this gene may be responsible for variations in plasma enzyme levels. The association of NOS3 variants with coronary artery disease (CAD) varies in different ethnicities. The current study aimed to determine the association of NOS3 Glu298Asp (rs1799983) with CAD and blood lipid levels in Pakistani subjects. Six hundred thirty-six samples (412 cases, 224 controls) were genotyped by TaqMan allelic discrimination assay and serum total cholesterol, and High Density Lipoprotein cholesterol (HDL-C)/Low Density Lipoprotein cholesterol (LDL-C) and triglycerides were measured...

INTRODUCTION: Third degree or complete heart block (CHB) is a medical emergency and usually requires permanent pacemaker placement. CHB can be caused by cardiac ischemia or non-ischemic conditions such as infiltrative diseases or fibrosis. The purpose of this study is to identify the baseline clinical characteristics associated with ischemic versus non-ischemic causes of complete heart block and compare their outcomes. MATERIALS AND METHODS: An institutional review broad approval was granted by the Cleveland Clinic Health System...

Kawasaki disease is a systemic vasculitis with an acute and self-limited course. The incidence of the disease differs widely among ethnic groups and is higher in the Asian populations. In Italy, no recent data are available. We studied the epidemiology of Kawasaki disease in the years 2008-2013 in children 0-14 years old in Italy using hospital ICD-9 discharge codes with a thorough data cleaning for duplicates in order to select the first hospital admission for the disease. The disease peaked in the first 2 years of life, with 85...

Circulating lipid concentrations are among the strongest modifiable risk factors for coronary artery disease (CAD). Most genetic studies have focused on Caucasian populations with little information available for populations of African ancestry. Using a cohort of ~2800 African-Americans (AAs) from a biobank at Vanderbilt University (BioVU), we sought to trans-ethnically replicate genetic variants reported by the Global Lipids Genetics Consortium to be associated with lipid traits in Caucasians, followed by fine-mapping those loci using all available variants on the MetaboChip...

We assessed the relationships among adult height, coronary artery calcium (CAC) scores, incident atherosclerotic cardiovascular disease (ASCVD) events, and atrial fibrillation (Afib) in a multi-ethnic cohort. We used race/ethnicity -specific height (dichotomized by median and quartiles) as the predictor variable within the four race/ethnic groups in the Multi-Ethnic Study of Atherosclerosis (N = 6,814). After a mean of 10.2 years of follow-up (2000-2012), 556 ASCVD events (8.2%) and 539 afib events (7.9%) occurred...
