Heart health is a significant aspect of overall well-being, especially for older individuals or those who have experienced symptoms related to cardiac health. One of the tools used to assess the functioning of the heart is a stress test. By learning more about what stress tests are and how they work, you can better understand their role in maintaining heart health and exploring potential treatment options.
What Is a Stress Test?
A cardiac stress test (CST) is an assessment performed to evaluate how well the heart functions during physical activity. Since your heart works harder during exercise, it requires more oxygen, causing it to pump blood faster. A stress test monitors how your heart handles this increased workload.
This test often focuses on identifying irregular blood flow to the heart and other abnormalities. It provides valuable insights into symptoms such as chest pain, shortness of breath, or fatigue, which may indicate underlying heart conditions. By mimicking the physical demands caused by exercise, the test can reveal issues that might not be apparent when the heart is at rest.
Possible Conditions
By identifying these symptoms and their underlying conditions, healthcare providers can determine a more tailored path forward for your heart healthcare and management. Some common heart conditions a CST can help detect include:
- Arrhythmia: A condition where the heart beats irregularly, which may become noticeable during exertion.
- Coronary Heart Disease: A condition caused by reduced blood flow to the heart, often due to plaque buildup in the arteries.
- Heart Valve Issues: Problems with the valves that control the flow of blood in the heart.
- Heart Failure (in early stages): The reduced ability of the heart to pump blood effectively.
How a CST Is Performed?
Understanding the process of a CST can help demystify your symptoms and alleviate any concerns. Here is what to expect during this assessment:
Before the Test
Before the CST begins, your doctor may ask about your medical history, current medications, and any specific symptoms you’ve been experiencing. Electrodes will be attached to your chest, arms, and legs, which connect to an electrocardiogram (ECG) machine. This equipment tracks your heart’s electrical activity at rest and during exertion. Your blood pressure will also be monitored throughout the test.
During the Test
The most common stress testing method involves walking on a treadmill or pedaling a stationary bike. The activity starts at a slow or moderate pace and gradually increases in speed or incline, requiring your heart to pump faster. For individuals unable to exercise, medication may be administered to mimic the effects of physical exertion on the heart. Throughout the test, the ECG machine tracks changes in your heart’s rhythm while healthcare providers observe your blood pressure and monitor for any symptoms you may experience.
After the Test
When you’ve completed the active portion of the test, or if you experience any concerning symptoms, the activity is stopped. Your heart and blood pressure will continue to be monitored while you rest, confirming they return to typical levels. The collected data is then reviewed by your physician, who will analyze the results to determine the next steps.
