What Is a Cardiac Stress Test?
A cardiac stress test evaluates how your heart responds to physical exertion or pharmacologic stimulation. By monitoring your heart’s electrical activity, blood pressure, and — in some tests — imaging data during increased demand, your cardiologist gains critical insight into coronary artery disease, arrhythmias, and overall cardiovascular fitness that cannot be detected at rest.
Types of Stress Tests We Offer
Exercise Treadmill Test (ETT) — The standard stress test. You walk on a treadmill at increasing speed and incline while we continuously record your ECG, heart rate, and blood pressure. If you develop symptoms, ST-segment changes, or blood pressure abnormalities, the test is stopped and results are immediately analyzed.
Nuclear Stress Test — Combines treadmill exercise (or pharmacologic stress) with radiotracer imaging to produce detailed pictures of blood flow through the heart muscle at rest and under stress. Particularly useful for evaluating known or suspected coronary artery disease, localizing areas of ischemia, and assessing myocardial viability after a heart attack.
Stress Echocardiogram — Uses echocardiography (ultrasound) before and immediately after exercise to compare cardiac wall motion. Identifies regional wall motion abnormalities that indicate blocked coronary arteries.
Pharmacologic Stress Test — For patients unable to exercise adequately, medications such as adenosine, regadenoson, or dobutamine are used to simulate the cardiovascular effects of exercise. Combined with nuclear or echo imaging for full diagnostic value.
Reasons Your Doctor May Order a Stress Test
- Chest pain or pressure during exertion
- Unexplained shortness of breath
- Palpitations or irregular heartbeat
- Evaluation of known coronary artery disease
- Pre-surgical cardiac risk assessment
- Follow-up after heart attack or cardiac procedure
- Evaluation of exercise capacity and heart failure management
What to Expect at Your Stress Test Appointment
Wear comfortable athletic shoes and loose clothing. You will be asked to fast for 3–4 hours before the test and to avoid caffeine for 24 hours. ECG electrodes and a blood pressure cuff will be placed before you begin. Our cardiologists and trained staff monitor you continuously throughout the test and immediately review results. Most patients are in and out within 60–90 minutes for a standard test.

Frequently Asked Questions
How do I prepare for a stress test?
Fast for 3–4 hours before the test. Avoid caffeine (coffee, tea, energy drinks) for 24 hours. Wear comfortable shoes and loose clothing. Bring a list of your current medications — some medications may need to be held before the test per your doctor’s instructions.
Is a stress test dangerous?
Cardiac stress tests are very safe when performed in a properly equipped medical office with a cardiologist present. Serious complications such as heart attack or arrhythmia are extremely rare (less than 1 in 10,000 tests). Our staff are trained in emergency cardiac response.
What does an abnormal stress test mean?
An abnormal result may indicate reduced blood flow to part of the heart (ischemia), an arrhythmia triggered by exercise, or reduced exercise capacity. Your cardiologist will discuss what the findings mean and what further testing or treatment may be recommended.
How long does a nuclear stress test take?
A nuclear stress test typically takes 3–4 hours including two separate imaging sessions (rest and stress) and the exercise or pharmacologic stress portion. You will receive a mild radiotracer injection that is safe and eliminated from your body within 24 hours.
Can I drive home after a stress test?
After a standard exercise stress test, most patients can drive themselves home. If you received sedation or a pharmacologic stress agent, you will need a driver. Our staff will advise you before your appointment.
