Diagnostic Testing
If you are experiencing symptoms of heart and vascular disease, have a family history of risk factors of cardiovascular disease, or are simply seeking peace of mind, the Arizona Heart Institute invites you to partner with us to create a personalized health care plan for you. Following a thorough history and physical, we may recommend one or more of the following tests to better understand your heart and vascular health:


Electrocardiogram (EKG)
An EKG evaluates heart rate (fast or slow), rhythm (regular or irregular), the size of the heart chambers, and in some cases, may reveal signs of a previous or current heart attack or other indications of heart disease. This test is painless and requires no injections or incisions.

Blood and Urine Tests
Chemical analyses of body fluids to examine blood cell counts, levels of components such as sodium, calcium, potassium, and proteins, blood lipids (such as cholesterol, lipoproteins, and triglycerides), and blood sugar help to assess cardiovascular health.

Echocardiogram
This test uses high-frequency sound waves (ultrasound, or “echo”) to create a moving picture of the heart. An echo shows the size and shape of the heart, how well the heart is pumping, and how well the heart valves are working.

Exercise Stress Test
While walking or jogging on a treadmill, this test shows how the heart responds to exercise. For individuals who are very short winded or do not have sufficient strength to walk on a treadmill, your physician may recommend an alternative stress test using medications which speed up the heart to mimic exercise.

Nuclear Stress Test
A nuclear stress test measures blood flow to your heart muscle both at rest and during stress on the heart. It's performed similar to a routine exercise stress test, but can also reveal areas of low blood flow through the heart and areas of damaged heart muscle.

Doppler Ultrasound
This test uses high-frequency sound waves (ultrasound) to create a moving picture of blood flow through the aorta, carotid arteries and arteries and veins of the legs. The ultrasound is non-invasive and requires no injections or incisions.

Ankle/Brachial Index
Special blood pressure cuffs are used to measure pressure differences of the arm and leg. A drop in pressure between these two segments indicates possible narrowings in the leg’s circulation, also known as peripheral arterial disease (PAD). Further testing with ultrasound and angiography can determine the location and severity of disease.
