What qualifies as coronary artery disease?
(KOR-uh-NAYR-ee AR-tuh-ree dih-ZEEZ) A disease in which there is a narrowing or blockage of the coronary arteries (blood vessels that carry blood and oxygen to the heart). Coronary artery disease is usually caused by atherosclerosis (a buildup of fatty material and plaque inside the coronary arteries).
What is the gold standard for diagnosing coronary artery disease?
Coronary Angiography Coronary angiography, also called cardiac catheterization, is a minimally invasive study that is considered the gold standard for diagnosing coronary artery disease.
What level of HDL is considered as a high risk for CAD?
The National Cholesterol Education Program (NCEP) defines an HDL level <40 mg/dL as a categorical risk factor for CAD.
How do you know if you have plaque in your arteries?
Sometimes the only way to know if your arteries are clogged is to undergo a screening test such as a carotid Doppler ultrasound, which can check for blockages that might put you at risk of a stroke.
What blood tests show coronary artery disease?
Troponin T is a protein found in heart muscle. Measuring troponin T using a high-sensitivity troponin T test helps health care providers diagnose a heart attack and determine the risk of heart disease. An increased level of troponin T has been linked with a higher risk of heart disease in people who have no symptoms.
What is a good LDL HDL ratio?
The higher the ratio, the higher the risk. Most healthcare providers want the ratio to be below 5:1. A ratio below 3.5:1 is considered very good.
What test shows clogged arteries?
A CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack. Prior to the test, a contrast dye is injected into the arm to make the arteries more visible. The test typically takes 30 minutes to complete.
What does an artery blockage feel like?
The symptoms of an artery blockage include chest pain and tightness, and shortness of breath. Imagine driving through a tunnel. On Monday, you encounter a pile of rubble. There is a narrow gap, big enough to drive through.
