CATHGEN: "CATHeterization GENetics Research Project“

Project description:

Related HEI project “Air quality by genomics interactions in a cardiovascular disease cohort”:

This project is designed to investigate the effects of acute and chronic air pollution exposure on acute and chronic cardiovascular disease. Gene-by-air quality effects on newly identified cardiovascular risk biomarkers and blood-based whole genome gene expression profiles as biological mediators of acute cardiovascular events (myocardial infarction and hospitalization) and cardiovascular disease state (extent of coronary artery atherosclerosis) will be examined.

For this purpose the CATHGEN cohort of 9323 individuals undergoing coronary artery catheterization (collected 2001-2011) is used for analyses. The CATHGEN cohort, collected at Duke, includes individuals with and without coronary atherosclerosis.

The research is driven by three hypotheses: 1) Air quality, including PM2.5 and ozone, are related to prevalence of chronic cardiovascular disease (both coronary and peripheral) and incidence of acute cardiovascular events; 2) Specific genetic variants mediate the interaction of air quality and cardiovascular disease and incident events; 3) The interaction of genetic variants and air quality on cardiovascular disease and incidence events are in turn mediated by air quality-induced modifications of gene expression and circulating metabolic intermediates.

The Institute of Epidemiology II focuses on the investigation of acute and chronic effects of exposure to PM2.5, PM components, ozone and air temperature on cardiovascular events and biomarkers of cardiovascular risk including ECG- and blood parameters, metabolites and lipoproteins.
