People faint most often because a sudden drop in blood pressure is sure to get up too quickly. Common causes involve insufficient blood flow to the brain and therefore insufficient oxygen supply to the brain.

poor circulation (also called Claudication) refers to leg pain caused by exercise and that improves with rest. Also called intermittent claudication, it's temporary leg pain. Peripheral vascular disease (PVD) and poor circulatory system The calf muscles are often affected, but the feet, thighs and buttocks can also be painful.

TIt is a narrowing of the carotid artery. This artery is the main artery that carries oxygenated blood to the brain. Aortic stenosis occurs in 5 out of 1,000 people 50 - 60 years old and is more common in 100 out of 1,000 people older than 80.

The aorta is a large, important artery attached to the left side. side of the heart other medium blood vessels from the aorta which carries blood and oxygen to the body. Coarctation is an abnormal narrowing of the aorta.

Triglycerides are a type of fat (lipid) found in the blood most commonly in the body. Cholesterol is another. Store them in fat cells for later use. Triglycerides are the primary source of energy if eaten in normal amounts is essential to good health.

The speed and pattern of your heartbeat is called your heart rhythm and can be felt by feeling the pulse. Your heart rhythm is set by signals from the heart’s electrical system. An abnormal heart rhythm is called an arrhythmia. Atrial fi brillation is one type of abnormal rhythm. The muscle looks as if it is wiggling instead of squeezing (contracting).

Aortic valve stenosis (AVS) is a disorder in which the opening of the aortic valve in the heart is too small or stiff. A valve is like a doorway, and the aortic valve is one of four valves controlling blood fl ow inside the heart. A normal aortic valve has three fl aps (leafl ets). The heart sends oxygen rich blood to the body through this valve. In AVS, the heart works harder to pump blood through the smaller opening. This extra effort can make the heart grow big and weak. AVS occurs about three times more often in men than in women.

The aorta is the large artery that leaves the heart from the leftlower chamber (ventricle). The aortic valve is between the left ventricle and the aorta. Aortic insuffi ciency (or aortic regurgitation) is the leaking of blood from the aorta through the aortic valve into the left ventricle when the ventricle contracts. Aortic insuffi ciency causes the left ventricle to get larger because of the extra blood in it.

An abdominal aortic aneurysm is a bulging of the aorta, the main blood vessel that takes blood from the heart to organs and tissues in the lower half of the body. The aorta is the largest artery in the body, and a stretching or bulging in the aorta is dangerous because this weakened area in the wall of the aorta may split open (rupture) if not treated. These aneurysms commonly occur in people older than 60 and affect men more than women. Ruptured aneurysms are the 10th leading cause of death in men older than 55 in the United States.

It is a type of illness caused by deep vein thrombosis, mainly in the veins in the leg muscles. and other parts can be born. A blood clot slows down the flow of blood and causes swelling, redness, and pain.

Also known as APS, a group of people with more blood clots than normal. and have antiphospholipids in the blood Antioxidants are substances produced by the body's immune defenses that are created to fight germs. in which the auto-immunity condition occurs, destroying the immune system itself born in a pregnant woman, for example miscarriage or premature baby

Blood pressure is the pressure of blood on the walls of arteries caused by the pumping action of the heart. Increased blood pressure puts a strain on the circulatory system. directly affects the occurrence of diseases of the vascular system
