Test For Clogged Arteries

When arteries that nourish the heart are clogged it can lead to a weakening of this very important muscle. That's why doctors often use an exercise stress test to identify this condition, particularly if an individual is experiencing chest pain. Early detection is key, as it short-circuit development of coronary artery disease and help maintain a strong heart.


Instructions


Test Procedure


1. Visit your doctor for a physical exam, as she can determine whether you have a heart condition and could benefit from an exercise stress test. She will measure your heart rate and blood pressure to evaluate the strength of blood flow through your body, and she may also test your blood cholesterol level.


2. Prepare for the exercise stress test by not eating, drinking or smoking for at least four hours before the test, and don't consume any caffeine during the preceding 12 hours. Let your doctor know if you are taking heart or diabetes medications. When you go to the doctor's office for the test, make sure you're wearing soft-soled walking shoes and comfortable clothes.


3. During the test visit, a doctor or a technician places electrodes on your chest to monitor your electrocardiography. These electrodes connect you to an electrocardiograph machine, known as an ECG or EKG, which monitors your heart activity.


4. Before you begin exercise, a technician performs an EKG and measures your resting heart rate and blood pressure.


5. Next, you'll exercise on a treadmill or stationary bicycle wearing a blood pressure cuff. The test requires that you gradually increase the strenuousness of the workout until you reach a target heart rate, all while a doctor or technician monitors your EKG and heart rate and watches for any symptoms. She will also periodically test your blood pressure. It is important to confide in the doctor about any symptoms or discomfort that you feel so she can diagnose you correctly.


6. During a cool down period a doctor or technician will take EKG, heart rate and blood pressure exams and monitor your heart rate until it returns to normal.


7. Finally, you'll learn how your heart responded to the tests and whether your body functioned in a healthy or stressed manner. Ultimately, she'll let you know about if you are at risk of developing coronary artery disease and whether further evaluation is needed.
