Common medical tests to diagnose heart disease include blood tests to detect markers, an electrocardiogram (ECG) to record heart activity, and an exercise stress test to evaluate heart function during exertion. Other tests include an echocardiogram to assess heart structure, a nuclear cardiac stress test to visualize blood flow, a coronary angiogram to detect blockages, an MRI for detailed heart images, and a coronary CT angiogram (CCTA) to examine the coronary arteries.
