Analysis of Heart Muscle Function in Patients With Heart Disease and Normal Volunteers

Completed

Conditions studied: Cardiomyopathy, Hypertrophic, Coronary Disease, Healthy, Myocardial Ischemia, Syndrome X

In brief

Myocardial ischemia is a heart condition in which not enough blood supply and oxygen reaches the heart muscle. Damage to the major blood vessels of the heart (coronary artery disease), minor blood vessels of the heart (microvascular heart disease), or damage to the heart muscle (hypertrophic cardiomyopathy) can cause myocardial ischemia. Any of theses three conditions can cause patients to experience chest pain and other symptoms as well as cause the heart to function improperly. In order to detect myocardial ischemia researchers can use tests to measure the movement of the walls of the heart. Walls receiving inadequate supplies of blood often move less and occasionally move in the opposite direction. Some of the tests may require patients to receive injections of radioactive tracers. The radioactive material acts to enhance 3 dimensional pictures of the heart and helps to identify areas of ischemia. The purpose of this study is to determine whether 3-dimensional imaging (tomography) with radioactive tracers can provide more important information about heart wall function than routine diagnostic tests.
