In the pulmonary arteries, atherosclerosis occurs when, and only when, pulmonary arterial blood pressure approaches sytemic arterial pressure. ...Read moreSee 2 more doctor answers
Why is it that aspirin can prevent blood clots in arteries but not in veins? If it inhibits platelet function, why does it not do that everywhere?
It does: It does inhibit platelet function. It does inhibit clot formation in veins. Its just that venous clots aren't quite as serious an issue. We worry about clots in the arteries to your heart that can lead to heart attack or an artery to your extremity leading to cold leg or arm. People do get clots in their veins, they are called DVTs but they usually aren't fatal. ...Read more
Potential Problem: Ovarian varicosities are usually due to increased venous pressure from either stenosis or occlusion of the iliac, hypogastric or pelvic veins.

Sinusoids: are specialized blood vessels in the liver.

Lung problems can also cause this congestion. Cirrhosis may ultimately result. It is serious and needs careful analysis. ...Read moreSee 2 more doctor answers
Ensure blood supply: The question is a little vague but i will try to explain. The small arteries to the heart (the coronary arteries) are what supply blood to the hearyt to keep it pumping. The big artery from the heart supplies the systemic circulation. If the small arteries get blocked, then you have a heart attack and may die. Any surgical proceedure may put enough stress on the heart to have a heart attack. ...Read more

Sick heart muscle: The ef is the ejection fraction, a measurement of heart function that estimates the percent of the blood volume that is ejected with each heart beat. Normal is usually > 50%. Dilated cardiomyopathy is a condition in which the heart muscle is sick and functions poorly. Because the heart muscle is weakened, it can't pump normally and therefore ejects less blood with each heart beat. Thus a low ef. ...Read more
Blocked arteries is a condition in which a person has decreased or no blood flow in one or more of his arteries, due to obstructions inside the artery such as thick plaques, floating clumps of broken plaques, blood clots, etc... Severe compression due to a problem on the outside of an artery can also ...Read more
