How long does it take to get results from a chemical stress test?
A patient should allow approximately two to four hours for the entire test, including the preparation. Dual isotope and technetium stress testing takes less time than thallium. The first part of the test generally takes an hour. The second part takes anywhere from 15 to 30 minutes.
A standard exercise stress test uses an EKG (electrocardiogram) to monitor changes in your heart's electrical activity. Imaging stress tests take pictures of blood flow in various parts of your heart. Abnormal test results may be due to coronary heart disease (CHD) or other factors, such as a lack of physical fitness.
- Answer: Well, no test is perfect. Certainly a stress test is a very good screening test in most cases for most patients for the presence of significant coronary artery disease. You may have a negative stress test one year and six months down the line, or a year down the line, your arterial disease can progress.

- Consult your physician about going off beta blockers for 48 hours and calcium channel blockers 24 hours before your exam. Do not eat or drink for three hours before your appointment.

The "stress" part of a stress test (when your heart is working hard) usually lasts about 15 minutes or less. However, there's prep time before the test and monitoring time afterward. Both extend the total test time to about an hour for a standard stress test, and up to 3 hours or more for some imaging stress tests.
- If a patient cannot exercise, medication is given to stress the heart (called a pharmacological stress test). These tests take 3 to 4 hours. In addition, they may not eat or drink any caffeinated foods or beverages or take caffeine-containing medications for 24 hours before the test.
- A cardiac stress test (also referred to as a cardiac diagnostic test, cardiopulmonary exercise test, or abbreviated CPX test) is a cardiological test that measures the heart's ability to respond to external stress in a controlled clinical environment. The stress response is induced by exercise or by drug stimulation.
- Your doctor may recommend a stress test to: Diagnose coronary artery disease. Coronary artery disease develops when these arteries become damaged or diseased — usually due to a buildup of deposits containing cholesterol and other substances (plaques). Diagnose heart rhythm problems (arrhythmias).
