I'm really worried about heart health. Could you tell me what tests are usually done to find heart disease? And what are the early signs of a heart attack I should watch out for? Also, what can I do to prevent a heart attack from happening in the first place?

To detect heart disease in the body, tests such as Electrocardiogram (ECG), Echocardiogram, Stress test, Cardiac catheterization, and CT scan may be done. Symptoms of a heart attack may include chest pain or discomfort, upper body pain, shortness of breath, nausea, lightheadedness, and cold sweats. To prevent a heart attack, it is important to maintain a healthy lifestyle by exercising regularly, eating a balanced diet low in saturated fats, managing stress, avoiding smoking, and controlling conditions like high blood pressure and diabetes.
