Stress tests are performed by a doctor or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia. Your doctor uses the stress test to determine if there is adequate blood flow to your heart during increasing levels of activity, evaluate the effectiveness of your heart medications to control angina and ischemia, determine the likelihood of having coronary heart disease and the need for further evaluation, check the effectiveness of procedures done to improve blood flow within the heart vessels in people with coronary heart disease, identify abnormal heart rhythms, and to help you develop a safe exercise program. Preparation for these types of stress tests will vary. Ask your doctor about any specific instructions. Read more: Exercise Stress Test Article
