Which coronary artery is called artery of sudden death?

The left anterior descending artery (also LAD, anterior interventricular branch of left coronary artery, or anterior descending branch) is a branch of the left coronary artery. Blockage of this artery is often called the widow-maker infarction due to a high death risk.

Can coronary artery disease cause sudden death?

Coronary artery disease is the most common cause of sudden cardiac death, accounting for up to 80\% of all cases. Cardiomyopathies and genetic channelopathies account for the remaining causes. The most common causes of non-ischemic sudden cardiac death are cardiomyopathy related to obesity, alcoholism, and fibrosis.

Which artery causes most heart attacks?

The leading cause of heart attack is coronary artery disease — narrowing or blockage of the coronary arteries. This narrowing process is the result of buildup of fatty substances, called plaques, on artery walls.

Which artery is the Widowmaker artery?

A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.

What is distal LAD?

The distal segment is from the halfway point to the apex. The length of the LAD usually measures approximately 10 cm to 13 cm long. Branches of the LAD are called diagonal branches and septal perforator branches.

What is coronary artery atheroma?

Coronary heart disease (CHD) is usually caused by a build-up of fatty deposits (atheroma) on the walls of the arteries around the heart (coronary arteries). The build-up of atheroma makes the arteries narrower, restricting the flow of blood to the heart muscle. This process is called atherosclerosis.

Is the right coronary artery The Widowmaker?

When the main artery down the front of the heart (LAD) is totally blocked or has a critical blockage, right at the beginning of the vessel, it is known as the Widow Maker.
