Medical Tests for Heart Disease

Your doctor will check your blood pressure and do a fasting blood test to check your cholesterol, a type of fatty substance that can contribute to plaques in your arteries. He or she might also do a blood test to check the levels of proteins that are markers of inflammation in the body and suggest you have an electrocardiogram (ECG or EKG). This test looks at electrical activity in your heart. A chest x-ray will show whether your heart is enlarged or your lungs have fluid in them; both can be signs of heart failure. The doctor might do a blood test for brain natriuretic peptide (BNP), a hormone that increases in heart failure. If the cardiologist needs to determine your heart or valve function, he or she may order an echocardiogram, a painless test which uses sound waves to produce images of your heart in motion
