Document Summary
Lecture 19: nutrition & disorders of the heart & blood vessels. Cardiovascular disease: coronary heart disease (chd, most common (52% of cardiovascular disease cases, caused by atherosclerosis in coronary arteries, stroke, second most common, decreased blood ow to the brain. Bile acid sequestrants: reduce cholesterol synthesis in the liver, work like soluble ber, bind up cholesterol & bile acids and excretes them, reduces blood cholesterol. Nicotinic acid: reduces triglycerides and raises hdls. Anticoagulants & aspirin: anticoagulants suppress blood clotting, aspirin is a blood thinner. Blood pressure meds: treat hypertension and maintain a good bp. Hypertension: a ects 1/3 of adults in the us, blood pressure: force exerted by blood on the artery walls, desirable bp = less than 120/80, prehypertension = 120-139/80-89, hypertension = greater than 140/90, factors in uencing bp, cardiac output. How much blood the heart can pump. Increases when hr or blood volume increases. Higher cardiac output makes higher bp: peripheral resistance.
