Cardiac Stress Test Q & A

 What is a stress test?

A stress test measures how your heart performs under different levels of stress. Making your heart work harder makes it easier for your doctor to diagnose problems. At Chinatown Cardiology, heart stimulation is either provided by exercising on a treadmill or injection of intravenous vasodilators.The latter is used when medical problems prevent a person from being able to complete the necessary exercise; this is called a pharmacologic stress test. During the stress test, your heart rate and blood pressure are monitored throughout.

What preparation is required for a stress test?

You will need to fast for 3 hours before the test, and not drink or eat anything containing caffeine for 12 hours before the test. Your cardiologist may also advise you not to take specific medications that could impact results.

What is a nuclear stress test?

Commonly known as myocardial perfusion imaging, a nuclear stress test utilizes the distribution of an intravenous dose of the radiotracer (Tc-99m Sestamibi or Thallous Chloride 201) to capture images of the blood flow using a special camera.  Photos are taken before and after exercise to assess the patient’s arteries.  The radioisotopes found within the heart muscles help identify areas of reduced blood flow to the heart muscles. During these exams, you will be closely monitored by healthcare personnel at our facility to ensure you are well.

Who needs a stress test?

A stress test may be ordered if:

  • You have been experiencing chest pains or shortness of breath.
  • You feel lightheaded or faint.
  • Experience a rapid heartbeat during exercise.
  • You’ve been diagnosed with coronary heart disease or recently suffered a heart attack.
  • You recently had an angioplasty with or without stent placement. The stress test will measure the effectiveness of these procedures.
