The coronary arteries can constrict as a response to various stimuli, mostly chemical. This is known as a coronary reflex. There is also a rare condition known as spontaneous coronary artery dissection, in which the wall of one of the coronary arteries tears, causing severe pain. [10]
Cast of coronary arteries (right = yellow, left = red) There are some anastomoses between branches of the two coronary arteries. However the coronary arteries are functionally end arteries and so these meetings are referred to as potential anastomoses, which lack function, as opposed to true anastomoses like that in the palm of the hand. This ...
Coronary artery disease, or coronary heart disease, is the most common type of heart disease. It occurs when fatty deposits called plaques build up in your arteries, making them thicker-walled ...
The right coronary artery supplies the right atrium, right ventricle, and lower posterior sections of the left ventricle. The right coronary artery also supplies blood to the atrioventricular node (in about 90% of people) and the sinoatrial node (in about 60% of people). The right coronary artery runs in a groove at the back of the heart and ...
Coronary artery bypass grafting (CABG): A bypass surgery improves blood flow to your heart by taking another blood vessel from somewhere else in your body and using it to create a new passage for ...
Coronary artery disease, also known as "ischemic heart disease", [24] is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and is one of the causes of sudden cardiac death. [25] It is within the group of cardiovascular diseases of which it is the most common type. [26]
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart.
While coronary disease occurs when the arteries that supply the heart become blocked, valvular disease indicates that the heart’s valves aren’t working well. Unlike a sudden cardiac event ...
