Cardiac CT angiography, a noninvasive test to check for clogged heart arteries, is now considered a first-line test for people with suspected heart disease. It appears to be just as effective as traditional angiography but with fewer risks.
Tests to help diagnose or watch coronary artery disease include: Blood tests. Blood tests can check blood sugar and cholesterol levels. A high-sensitivity C-reactive protein (CRP) test checks for a protein linked to inflammation of the arteries. Electrocardiogram (ECG or EKG). This quick test checks the electrical activity of the heart.
Determine if blockages are present in the coronary arteries. 6. Exercise cardiac stress test: Also called an exercise tolerance test (ETT), this test shows whether your heart's blood supply is sufficient and if your heart rhythm is normal during exercise on a treadmill or stationary bicycle.

Using blood tests to understand your risk of coronary artery disease is a proactive approach to a healthier heart. Work with your healthcare provider to understand your results and determine the best next steps.
