Cardiac Diagnosis

MRMC offers a variety of ways to diagnose and treat issues of the heart. In addition to the common and more traditional diagnostics, such as electrocardiograms (EKG's), stress tests, and blood tests, our cardiopulmonary department offers state-of-the-art echocardiograms and dopplers to evaluate the blood circulation in arteries and veins throughout the body. Sometimes nuclear stress tests are utilized so that a more specific reading can be made.

Any issue with the heart can be a frightening experience. When one has chest pain, an EKG is usually the first test ordered. This is a relatively basic screening exam which can tell the physician if you are currently having a cardiac event, or if you have had one in the past. Next, the physician may order a Treadmill Stress Test which has a higher accuracy, since it is performed with the heart under stress.

The clinical term for "clogged arteries" or blockage is coronary artery disease, which slows the blood flow to the heart, and consequently, chest pain occurs. Once the artery is completely blocked, the heart attack (otherwise known as an "MI" or myocardial infarction) occurs. If a blockage is noted on the diagnostic exam, your physician may order a nuclear stress test. However, if the result is negative or borderline, a heart cath may be ordered to check for Coronary Artery Disease.

Angioplasty (use of a balloon to open clogged arteries), cardiac bypass surgery, and other major procedures are still referred to the tertiary care facilities, often at the Texas Medical Center. You and your physician will discuss the options if this level of care is indicated.

Cardiac Diagnosis Testing

Heart attack patients may be asked to undergo a number of diagnostic tests and procedures. By learning what these tests are and why they’re being done, you’ll feel more confident. These tests are important and help the doctor determine if a heart attack occurred, how much your heart was damaged and also what degree of coronary artery disease (CAD) you may have. Your heart attack may have been the first symptom that you have CAD. The tests screen your heart and help the doctor determine what treatment and lifestyle changes will keep your heart healthy and prevent serious future medical events.

There are “non-invasive” and “invasive” diagnostic tests. Non-invasive tests don’t involve inserting needles, instruments or fluids into the body. Invasive procedures can include a simple needle prick for a blood test or shot, insertion of a tube, device or scope and major surgeries such as open-heart surgery.
