Pharmacologic Stress Testing

WHAT YOU SHOULD KNOW:

• Pharmacologic stress testing is also called a chemical stress test. This test uses medicine that makes the heart work just as it does when you exercise. It is usually done on those who have heart-related symptoms but cannot do an exercise stress test. The test may show your caregiver how healthy your heart is, or it may find a heart disease. The medicine used will cause the heart to work harder and pump more oxygen-rich blood to the body. Any change in the heart activity, including the rate and rhythm, is seen and recorded.
  
  
• Medicine that works on the blood vessels or muscles of the heart is given during and after the test. This is done through an intravenous (IV) tubing inserted in a vein, usually in the arm. Your heart activity will be recorded using an electrocardiogram (ECG), and watched on a screen. After all of the medicine has been given, ECG tracings are taken again for several minutes. Having a pharmacologic stress test done may diagnose your condition, and prevent other medical problems.

INSTRUCTIONS:

Medicines:

• Keep a written list of the medicines you take, the amounts, and when and why you take them. Bring the list of your medicines or the pill bottles when you see your caregivers. Learn why you take each medicine. Ask your caregiver for information about your medicine. Do not use any medicines, over-the-counter drugs, vitamins, herbs, or food supplements without first talking to caregivers.
  
  
• Always take your medicine as directed by caregivers. Call your caregiver if you think your medicines are not helping or if you feel you are having side effects. Do not quit taking your medicines until you discuss it with your caregiver. If you are taking medicine that makes you drowsy, do not drive or use heavy equipment.

Ask your caregiver when to return for a follow-up visit. Keep all appointments. Write down any questions you may have. This way you will remember to ask these questions during your next visit.

Healthy lifestyle:

• Eat a healthy diet: Eat a variety of healthy foods such as fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meat, and fish. Eating healthy food may help you have more energy. Ask your caregiver if you need to be on a special diet.
  
  
• Drinking liquids: Men 19 years old and older should drink about 3.0 Liters of liquid each day (close to 13 eight-ounce cups). Women 19 years old and older should drink about 2.2 Liters of liquid each day (close to 9 eight-ounce cups). Good choices for most people to drink include water, juice, and milk. If you are used to drinking liquids that contain caffeine, such as coffee, these can also be counted in your daily liquid amount. Some food items such as soup and fruit also add liquid to your diet. Ask your caregiver how much liquid you should have each day.
  
  
• Start exercising: Talk to your caregiver before you start exercising. Together you can plan the best exercise program for you. It is best to start slowly and do more as you get stronger. Exercise can help make your heart stronger and keep you healthy.
  
  
• Quit smoking: It is never too late to quit smoking. Smoking harms the heart, lungs, and the blood. You are more likely to have a heart attack, lung disease, and cancer if you smoke. You will help yourself and those around you by not smoking. Ask your caregiver for more information about how to stop smoking if you are having trouble quitting.

CONTACT A CAREGIVER IF:

• You feel dizzy and lightheaded.
  
  
• You have nausea (upset stomach) or vomiting (throwing up).
  
  
• You have questions or concerns about your test or medicine.

SEEK CARE IMMEDIATELY IF:

• You have trouble breathing all of a sudden.
  
  
• You have chest pain even after taking medicine.
