BACKGROUND: Apolipoprotein C-III (apoC-III), a small proinflammatory protein present on 6% to 7% of high-density lipoprotein (HDL) particles, defines a subspecies of HDL adversely associated with coronary heart disease in primarily white cohorts. In a multi-ethnic population free of clinical cardiovascular disease, we evaluated the relationship between apoC-III-defined HDL subspecies and subclinical markers of atherosclerotic pathology. METHODS AND RESULTS: We investigated cross-sectional associations between apolipoprotein A-I concentrations of apoC-III-defined HDL subspecies, measured via ELISA and imaging measures of subclinical atherosclerosis, among 4659 participants in the MESA (The Multi-Ethnic Study of Atherosclerosis) at baseline (2000-2002)...

High density lipoprotein (HDL) cholesterol levels and cholesterol efflux capacity (CEC) are inversely correlated with coronary artery disease (CAD) risk. Myeloperoxidase (MPO) derived oxidants and HDL proteome changes are implicated in HDL dysfunction in subjects with CAD in the United States; however, the effect of MPO on HDL function and HDL proteome in ethnic Chinese population is unknown. We recruited four matched ethnic Chinese groups (20 patients each): subjects with 1) low HDL levels (HDL levels in men <40mg/dL and women <50mg/dL) and non-CAD (identified by coronary angiography or cardiac CT angiography); 2) low HDL and CAD; 3) high HDL (men >50mg/dL; women >60mg/dL) with no CAD; and 4) high HDL with CAD...

OBJECTIVES: This study sought to evaluate the influence of race/ethnicity on the relationship between body mass index (BMI) and mortality in heart failure with preserved ejection fraction (HFpEF) and HF with reduced EF (HFrEF) patients. BACKGROUND: Prior studies demonstrated an "obesity paradox" among overweight and obese patients, where they have a better HF prognosis than normal weight patients. Less is known about the relationship between BMI and mortality among diverse patients with HF, particularly given disparities in obesity and HF prevalence...

BACKGROUND: Epidemiological analyses demonstrate that pneumonia survivors have a higher risk of myocardial infarction than people with similar load of risk factors for atherosclerotic cardiovascular disease (ASCVD) but without pneumonia. This may be due to a higher baseline burden of ASCVD in patients with pneumonia that is not captured by the accounting of known ASCVD risk factors in epidemiological analyses or to unfavorable accelerating effects of pneumonia on atherosclerosis. METHODS: We analyzed data from the Multi-Ethnic Study of Atherosclerosis...

Aims: Whether prevalence and mortality of patients with heart failure with preserved or mid-range (40-49%) ejection fraction (HFpEF and HFmREF) are similar to those of heart failure with reduced ejection fraction (HFrEF), as reported in some epidemiologic studies, remains highly controversial. We determined and compared characteristics and outcomes for patients with HFpEF, HFmREF, and HFrEF in a prospective, international, multi-ethnic population. Methods and results: Prospective multi-centre longitudinal study in New Zealand (NZ) and Singapore...

PURPOSE OF REVIEW: While the burden of cardiovascular disease (CVD) is on the decline globally, it is on the rise among South Asians. South Asians are also believed to present early with coronary artery disease (CAD) compared with other ethnicities. RECENT FINDINGS: South Asians have demonstrated a higher burden of premature CAD (PCAD) compared with other ethnicities. These findings are not limited to non-immigrant South Asians but have also been found in immigrant South Asians settled around the world...

Calcification of the coronary artery is a complex pathophysiologic process that is intimately associated with atherosclerosis. Extensive investigation has demonstrated the value of identifying and quantifying coronary artery calcium (CAC) in atherosclerotic cardiovascular disease (CVD) prognostication. However, over the last several years, an increasing body of evidence has suggested that CAC has underappreciated aspects that modulate, and at times attenuate, future CVD risk. The most commonly used measure of CAC, the Agatston unit, effectively models both higher density and higher area of CAC as risk factors for future CVD events...

Atherosclerotic coronary artery disease (CAD) and myocardial infarction (MI) as its most severe clinical complication remain the leading causes of mortality in the majority of countries. Despite the progress in the treatment of MI, quite often the patients, after the first-time MI, develop subsequently a variety of adverse cardiovascular events. In this retrospective study we evaluated the contribution of allelic variations in 9p21.3 locus and in 21 atherogenesis-related genes to the development of hard cardiac events in a cohort of patients of Russian ethnicity after the first acute MI during long-term follow-up (7-10 years)...

Myocardial infarction (MI) is a complex disease caused by combination of genetic and environmental factors. Although genome-wide association studies (GWAS) identified more than 46 risk loci which are associated with coronary artery disease and MI, most of the genetic variability inMI still remains undefined. Here, we screened the susceptibility loci for MI using exome sequencing and validated candidate variants in replication sets. We identified that three genes (GYG1, DIS3L and DDRGK1) were associated with MI at the discovery and replication stages...
