The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
A dilated portal vein (diameter of greater than 13 or 15 mm) is a sign of portal hypertension, with a sensitivity estimated at 12.5% or 40%. [18] On Doppler ultrasonography, a slow velocity of <16 cm/s in addition to dilatation in the main portal vein are diagnostic of portal hypertension. [19]
Cardiovascular disease in women is an integral area of research in the ongoing studies of women's health. Cardiovascular disease (CVD) is an umbrella term for a wide range of diseases affecting the heart and blood vessels, including but not limited to, coronary artery disease, stroke, cardiomyopathy, myocardial infarctions, and aortic aneurysms.
Information card published by the National Heart, Lung, and Blood Institute urging people with symptoms of angina to call the emergency medical services.. Because of the relationship between the duration of myocardial ischemia and the extent of damage to heart muscle, public health services encourage people experiencing possible acute coronary syndrome symptoms or those around them to ...
[1] [2] Pulmonary artery catheterization is a useful measure of the overall function of the heart particularly in those with complications from heart failure, heart attack, arrhythmias or pulmonary embolism. It is also a good measure for those needing intravenous fluid therapy, for instance post heart surgery, shock, and severe burns. [2]
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack.

For February's American Heart Month, WH breaks down the current research and personal stories of spontaneous coronary artery dissection (SCAD) in women. Thousands Of Women Have Had This Type Of ...
Rat models have shown decreased ET-B receptor expression in pulmonary arteries of cirrhotic and portal hypertensive animals, leading to a predominant vasoconstricting response to endothelin-1. [17] In portal hypertension, blood will shunt from portal to systemic circulation, bypassing the liver. This leaves unmetabolized potentially toxic or ...
