Coronary Artery Disease

Coronary artery disease (CAD) is the most common cardiovascular condition. CAD is a result of the deposition of plaque (fat deposits) in the coronary arteries, leading to their narrowing and blockage. Coronary artery disease can lead to other diseases including arrhythmia, heart failure, and even death caused by an acute heart attack.

Frequently Asked Questions

Can an ECG detect a blocked artery?

No, an electrocardiogram cannot detect blocked arteries. Blocked arteries are usually diagnosed with a nuclear stress test, cardiac pet scan, coronary CT angiogram, or traditional coronary angiogram.

What are the risk factors for coronary heart disease?

The traditional risk factors for coronary artery disease are high LDL cholesterol, low HDL cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women, and being older than 45. Lifestyle causes and pre-existing conditions such as obesity, and Type 2 Diabetes are also included. 

What diet should a person take with coronary artery disease?

Foods that are high in soluble fibre and low in saturated and trans fats are excellent choices. Oats, nuts, beans, fatty fish, and olive and canola oils are all foods that are good for your heart.
