Cardiac Imaging and Stress Tests
Cardiac imaging & stress tests in St. Louis
Screening examinations are tests performed to find disease before symptoms begin. The goal of screening is to detect disease at its earliest and most treatable stage. Screening tests may include laboratory tests to check blood and other fluids, genetic tests that look for inherited genetic markers linked to disease, and imaging tests that produce pictures of the inside of the body. These tests are typically available to the general population; however, an individual's needs for a specific screening test are based on factors such as age, gender and family history. In heart screening, individuals with no signs or symptoms of coronary artery disease — the most common form of heart disease — may be evaluated to measure: the amount of cholesterol carried in the blood known as low-density lipoproteins (LDL); blood glucose levels, the amount of sugar present in the blood; protein level in the blood; and blood pressure levels, the force of blood against the artery walls both when the heart beats and when it is at rest (systolic and diastolic, respectively). Depending on the results of initial screening tests and the presence of risk factors for coronary artery disease, your doctor may recommend additional testing, including: Electrocardiography (ECG or EKG), exercise cardiac stress test, echocardiography, cardiac CT for calcium scoring, coronary CT angiography (CTA), myocardial perfusion imaging (MPI) and coronary catheter angiography.
