To examine the associations of common variation in inflammation/thrombosis genes with intermediate quantitative phenotypes and subclinical coronary atherosclerosis in the Coronary Artery Risk Factor Development in Young Adults (CARDIA) Study, a large, bi-racial cohort study.
Atherosclerosis is a major determinant of coronary heart disease and is determined by the interplay of genetic and environmental risk factors. Although atherosclerosis tends to aggregate in families, it does not exhibit classical Mendelian segregation. Thus, the genes that determine an individual's risk of atherosclerosis likely involve multiple sites within genes and interactions between genes, all of which define a genetic risk that is modified by the host environment.
The genetic epidemiology study examines the associations of common variation in inflammation/thrombosis genes with intermediate quantitative phenotypes and subclinical coronary atherosclerosis in the Coronary Artery Risk Factor Development in Young Adults (CARDIA) Study, a large, bi-racial cohort study. The set of 25 candidate genes involve pathways (cytokines, chemokines, and their receptors; cellular adhesion molecules; and, coagulation proteins) and include several receptor-ligand pairs. Using cladistic analysis and the resources of the Program in Genomic Applications (PGA), the investigators will identify a limited set of single nucleotide polymorphisms (range 3-10 SNPs per gene) that characterize common haplotypes in these candidate genes within persons of African descent and European descent. DNA from the CARDIA Year 10 examination (n = 3,950 subjects) will be genotyped for the selected variants that characterize the common haplotypes. Data on the presence of common variants and haplotypes will be incorporated into the CARDIA Study database. Levels of two important intermediate phenotypes, fibrinogen and C-reactive protein (CRP) were previously determined. Non-invasive assessment of coronary atherosclerosis, defined as the presence of coronary artery calcification (CAC), was obtained on CARDIA participants at the Year 15 exam. Analyses will be stratified by race/ethnicity and focus on the associations of the common haplotypes with fibrinogen, CRP, and CAC measured in early adult life. Secondarily, the investigators will explore possible gene-gene and gene-environment interactions. The proposed multi-disciplinary collaboration should enhance the sensitivity and specificity of efforts to assess the associations of common variation in sets of inflammation/thrombosis candidate genes and cardiovascular risk in young adults.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)

Blood pressure levels that are between normotension and hypertension. Individuals with prehypertension are at a higher risk for developing cardiovascular diseases. Generally, prehypertension is defined as SYSTOLIC PRESSURE of 131-139 mm Hg and/or DIASTOLIC PRESSURE of 81-89 when the optimal is 120/80 mm Hg. For diabetics and other metabolism diseases the prehypertension is around 110-129/70-79 mm Hg.
