Which test is commonly used to assess stable angina?

A stress test is commonly used to assess stable angina because it evaluates how the heart performs under physical stress or exercise. During a stress test, the patient typically walks on a treadmill or pedals a stationary bike while their heart rate, blood pressure, and ECG are monitored. This helps determine how well the heart is functioning and whether there is a reduction in blood flow to the heart, which is indicative of stable angina.

The stress test specifically aims to provoke symptoms of angina or reveal any ischemic changes on the ECG, which would suggest that the coronary arteries may be narrowed or blocked. Additionally, it can help to guide treatment decisions and evaluate the effectiveness of interventions for patients with known coronary artery disease.

Other tests, such as an echocardiogram or cardiac catheterization, might be utilized in different contexts or as follow-up assessments but are not typically first-line assessments for stable angina. The electrocardiogram (ECG) can provide useful information but does not specifically assess the functional capability of the heart under stress in the same direct way that a stress test does.
