Coronary

Coronary refers to the blood vessels that supply the heart muscle with oxygen and nutrients. These vessels, known as the coronary arteries, are critical for heart function. When these arteries become blocked or narrowed, it can lead to conditions such as Coronary artery disease and Heart attack.

Anatomy of the Coronary Arteries

The coronary arteries are two main vessels that branch off from the aorta near the point where it leaves the heart. The right coronary artery supplies blood to the right side of the heart, the bottom portion of both ventricles, and the back of the septum. The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart.

Coronary Artery Disease

Coronary artery disease (CAD) is a condition in which the coronary arteries become narrowed or blocked due to a buildup of atherosclerotic plaque. This can reduce blood flow to the heart muscle, leading to symptoms such as chest pain (Angina), shortness of breath, and fatigue. In severe cases, it can cause a Heart attack.

Diagnosis and Treatment

Diagnosis of coronary artery disease typically involves tests such as an electrocardiogram (ECG), stress test, and coronary angiogram. Treatment options include lifestyle changes, medications, and procedures such as angioplasty and coronary artery bypass surgery (CABG).
