Arteria coronaria

Arteria Coronaria refers to the coronary arteries, which are the blood vessels responsible for supplying oxygen-rich blood to the heart muscle. These arteries play a crucial role in the cardiovascular system and overall heart health.

Anatomy

The coronary arteries originate from the aorta near the point where the aorta and the left ventricle of the heart meet. There are two main coronary arteries: the right coronary artery (RCA) and the left coronary artery (LCA). The LCA further divides into the left anterior descending (LAD) artery and the circumflex artery.

Function

The primary function of the coronary arteries is to supply blood to the heart muscle. They do this by branching out from the aorta and spreading across the surface of the heart, penetrating the heart muscle to deliver oxygen and nutrients.

Diseases

Coronary artery disease (CAD) is the most common type of heart disease and the leading cause of death worldwide. It occurs when the coronary arteries become narrowed or blocked due to the build-up of atherosclerotic plaques. This can lead to angina pectoris, myocardial infarction, or heart failure.

Treatment

Treatment for coronary artery disease can involve lifestyle changes, medication, and potentially procedures such as coronary angioplasty or coronary artery bypass grafting (CABG). The choice of treatment depends on the severity of the disease and the patient's overall health.
