Disorders and Diseases...
Arteriosclerosis- This common disease happens when fatty deposits in the arteries causes the walls to become stiff and that causes the walls to thicken. The causes are too much fat, cholesterol and calcium. This can cause stroke, or even heart attack.
Hypertension (high blood pressure) — This condition causes the heart to work harder and can cause problems like a heart attack, a stroke, or kidney failure.
Aortic Aneurysm- Will occur when the aorta is damaged and starts to bulge or eventually tear, which can cause serious internal bleeding. This weakness can be present at birth or the result of atherosclerosis, obesity, high blood pressure or a combination of these conditions.
Atherosclerosis- the hardening and thickening of the arteries, which causes plaque to develop in the arteries.
Deep vein thrombosis (DVT)- occurs when blood clots form in one of the deep blood veins in your body. Can be life threatening if travels to the lungs.
Arteriovenous malformations (AMVs)- are unusual tangles and knots of the blood vessels within an area of the circulatory system. Commonly develop right after or before birth. Can cause particularly severe problems or death.
