No lab tests: Coronary artery disease is mainly diagnosed by assessing one's. Cardiovascular risk as well as sorting out various symptoms. Lab tests to help here would be a full lipid panel as well as a CRP which is a marker of inflammation. These do not detect plaque but do help i risk analysis. D-dimmer is used for venous disease ie blood clots in legs or lungs.

Arteriograpy, Stress: An exercise stress test with ECG monitoring is a great initrial test to check for symptoms like chest pain and signs like st segment changes. The definitive test is coronary arteriography, which can visualize the inside of the arteries and detect atherosclerosis. A d-dimer test shows the presence of fibrin degradation products, indicative of a deep vein thrombosis or pulmonary embolism.

None: There are no blood tests that specifically show cad. There are many tests, however, that act as markers for CAD - e.g. Cholesterol, crp. The d dimer is not used for CAD at all. It is a marker for inflammation, including possible thromboembolism.

Dr Villaplana and another doctor agreed

Cholesterol: Lab tests do not detect impending heart disease.The risk factors for atherosclerosis and vascular disease could serve as markers of risk for cardiac disease. Elevated cholesterol and ldl, low hdl, increases triglycrides are usual risk factors. Other risk factors that are not lab tests are hypertension, smoking, excessive alcohol intake, lack of physical activity. D-dimer will not help.

None: The sad reality is that there's no blood test for atherosclerosis. The d-dimer test most assuredly will not. An ultra sensitive c-reactive protein will address the probability of developing buildup but will not tell you if you have it. Electron beam ct which provides calcium score gets you closer but is not a blood test. Please read my comment:.

Dr Ferdowsi agreed

Many tests.: An early test would be a stress test with an electrocardiogram or ecg. This is done until there are symptoms and/or st segment changes on ecg, and/or target heart rate is achieved. Thallium 201 imaging makes it more sensitive and specific. The definiitive test is coronary arteriography to see the arteries. A d-dimer test checks for fibrin degradation products for deep vein/lung (pe)thrombosis.
