Cardiac stress testing is a vital diagnostic procedure designed to evaluate the heart's response to increased levels of stress and activity. This non-invasive examination is especially useful in assessing the cardiovascular system's performance in individuals suspected of having heart conditions or those deemed at risk for cardiac issues. Whether through treadmill exercise or pharmacological means, patients undergo controlled physical exertion while closely monitored for changes in heart rate, blood pressure, and electrocardiogram (ECG) readings. The primary objective is to induce temporary stress on the heart, simulating the demands of physical activity, in order to identify any abnormalities or limitations in blood flow to the heart muscle. By diagnosing conditions such as coronary artery disease and determining exercise tolerance, cardiac stress testing plays a crucial role in shaping personalized treatment plans and guiding interventions for individuals with concerns related to heart health. The results obtained from this procedure offer valuable insights, aiding healthcare professionals in making informed decisions about patient care and lifestyle recommendations.
