Cardiac stress testing is a diagnostic procedure employed to evaluate the heart's ability to withstand increased levels of activity and stress. This non-invasive test aims to assess the cardiovascular system's performance, particularly in individuals with suspected heart conditions or those at risk for cardiac issues. During the test, the patient typically undergoes physical exertion, either through treadmill exercise or pharmacological means, while being closely monitored for changes in heart rate, blood pressure, and electrocardiogram (ECG) readings. The objective is to induce temporary stress on the heart, mimicking the demands of physical activity, to reveal any abnormalities or limitations in blood flow to the heart muscle. Cardiac stress testing is a valuable tool for diagnosing coronary artery disease, determining exercise tolerance, and guiding treatment plans for individuals with heart-related concerns. The results obtained from this test can provide crucial insights into a patient's cardiac health, helping healthcare professionals make informed decisions about appropriate interventions and lifestyle modifications.
