Coronary Artery Disease and Genetic Research: Indiana Health Study
Blood samples and health information (e.g., age at diagnosis, test results) are collected for the purposes of genetic research. The blood samples are assigned a number and stored in a repository for safe keeping until they are needed for a research project. Participants are persons who are healthy (not having high blood pressure, diabetes, or high cholesterol levels) or persons who have Coronary Artery Disease (CAD) and live in Indiana. Participants complete a questionnaire at the time the blood sample is drawn and are contacted once a year to update their health history. Researchers apply to the Fairbanks Institute for use of the blood samples and health information minus participant names and contact information. Their research is required to be related to find genes or substances made by genes that may be involved in Coronary Artery Disease with the purpose of improving the investigators understanding of the illness potentially leading to the development of new diagnostic tools for identifying the illness, new treatments,or preventative measures. This study will be repeated for other disorders like Diabetes and Cancer.
The purpose of this study is to create an extensively annotated bio-repository platform for hypothesis-driven research that will lead to advancements in the diagnosis, treatment and prevention of diseases common to the population of Indiana. The first phase of this research platform will be created by collecting blood samples from two groups of individuals in the Central Indiana community, one with documented evidence of coronary artery disease (CAD), and a second group of age, gender and ethnicity matched individuals without clinical evidence of CAD. Each individual's blood sample will be linked to their clinical, demographic and epidemiological information, gathered both retrospectively and prospectively. This will be repeated with individuals who have Cancer, Diabetes and potentially other illnesses.
This initial study will include 750 individuals with CAD (the CAD Group) and 750 individuals who are age, gender, and ethnicity matched to the CAD Group, but without presentation of clinical evidence of CAD (the Control Group). To reflect the growing representation of Hispanics in Central Indiana, Hispanics will be overly recruited in both groups so that the study population accurately reflects the general population of Central Indiana.
As this is a prospective, longitudinal study, follow-up of study subjects is intended to continue indefinitely, unless, of course, at any time, consent for further follow-up is withdrawn by the subject. Follow-up will include continuing access to the subject's medical record, as well as facilitating continued contact by telephone, to pursue data concerning changes in the subject's health. All subjects will be contacted by telephone, mail or email every twelve months to ask if they wish to continue participation in the study.
The collected dataset (made up of the collected blood samples linked to clinical and epidemiological information collected retrospectively and prospectively), will be used in medical research to find genes, or gene products such as RNA or proteins that will help in understanding the causes of disease and will guide the development of new treatments.

Medical and Biotech [MESH] Definitions
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.
Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.
