Which artery is called artery of sudden death?

Which coronary artery gets blocked the most?

The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.

Where is the most important artery?

The most important artery is the aorta. The aorta issues from the left ventricle of the heart and has an internal diameter of 2.5 cm, making it also the largest artery in the body.

What are the three main causes of strokes?

Which side of neck is carotid artery?

Overview. There are four carotid arteries, with a pair located on each side of the neck. This includes the right- and left-internal carotid arteries, and the right- and left-external carotid arteries. The carotid arteries deliver oxygen-rich blood from the heart to both the head and brain.

How can I check my carotid artery at home?

Can you unblock a carotid artery without surgery?

Other new non-surgical options to treat blockages in the carotid arteries include balloon angioplasty and stents. Both of these procedures use a catheter-guided balloon, inflated in the blocked area, to open up the carotid artery. A metal stent may be inserted to help keep the artery expanded.
