Thank you for your interest in our Blood Pressure Research Study. The American Heart Association is sponsoring us to investigate why patients develop high blood pressure, atherosclerosis (hardening of the arteries), and heart disease. There are two parts of our research program. The first part is a screening visit. At this visit you will be given a brief physical exam and will be asked questions concerning your medical history. During the same visit you will have your blood drawn for routine screening and genetic testing. You will also be asked to collect a urine sample for routine screening.
