Prevention & Diagnosis of Heart Disease
Other Diagnostic Tests
Other diagnostic tests used to detect and diagnose heart and vascular disease include:
This test may be ordered for those who have been experiencing lightheadedness, dizziness, or blacking out. The patient is placed on a table that tilts up to a standing position, allowing physicians to evaluate the body's cardiovascular response to this change in position. Blood pressure and heart rate are monitored during the test.
This test is used to evaluate blood flow to the heart while resting and after exercise. A small amount of radioactive tracer is injected into the vein. A gamma camera takes pictures of the heart to indicate which areas are not getting enough blood or oxygen.
During a PET scan, small amounts of radioactive molecules are used to measure cellular or biological functions, such as blood flow or glucose metabolism. Learn more about PET scans.
Vascular ultrasound is a noninvasive test used to examine blood flow and circulation in arms, legs and neck. It can also evaluate blood flow in the arteries, which signals presence, severity and location of narrowed area of the arteries.
