The Miami Heart Study at Baptist Health will be an observational, longitudinal and prospective cohort study in a target population of 4000 healthy subjects (40-65 years old) consisting of members from the Greater Miami Area (including eligible BHSF(Baptist Health South Florida) employees). Baseline examination will consist of (1) assessment for cardiovascular risk factors (including lifestyle and psychosocial factors); (2) screening for subclinical atherosclerosis using Coronary CT angiogram, Coronary Artery Calcium (CAC) testing, vascular 2D/3D ultrasound, endothelial function, arterial stiffness and (3) blood sampling for determination of traditional risk factors, advanced "omics" and biobanking. Participants will be followed yearly via telephone, email, or mail for change in health status with a focus on cardiovascular disease events, including acute myocardial infarction and other forms of coronary heart disease (CHD), stroke, and congestive heart failure; mortality; and for cardiovascular disease interventions.
