Echocardiography is a crucial diagnostic tool for assessing the structure and function of the heart and major blood vessels. However, due to the relatively small size of the coronary arteries, echocardiography cannot provide a comprehensive and clear view of these vessels. While it may not visualize all coronary arteries, echocardiography can assist in diagnosing myocardial infarction (heart attack). Following a heart attack, some heart muscle tissue becomes ischemic and necrotic, losing its contractile function. During an echocardiogram, this is observed as uncoordinated or absent wall motion in specific areas of the heart. By correlating these findings with the patient's clinical symptoms, electrocardiogram (ECG) results, and blood test outcomes, a definitive diagnosis of myocardial infarction can be made. In cases of acute myocardial infarction, if timely intervention is performed to reopen the blocked vessel and restore blood supply to the heart muscle, only a small portion of the muscle may be damaged, preserving most of its function. In such cases, echocardiography may not reveal any abnormalities in contractile function. Some patients with diabetes or elderly individuals may experience painless myocardial infarction, where they don't feel any symptoms and thus don't seek medical attention. These cases are often discovered during echocardiography performed for symptoms like chest tightness or shortness of breath, which are signs of reduced cardiac function.
