Cholesterol and cardiovascular disease Research Paper

Cholesterol and cardiovascular disease - Research Paper Example Keywords: Cholesterol, hypercholesterolemia, heart attack, statins INTRODUCTION Cholesterol is a fat, a sterol. It is one of the main constituents of the cell membranes. Animal cells exclusively manufacture cholesterol, so it is an animal fat. Cholesterol is insoluble in water and is classified on the basis of density into very low density lipoproteins, intermediate density lipoproteins, low density lipoproteins and high density lipoproteins. The elevated levels of cholesterol in the human body play a very drastic role. The most crucial among all the effects is its effect on heart. The related symptoms may also arise depending upon the quantity of it in the blood and organs. REALTION BETWEEN CHOLESTROL AND HEART DISEASE When the level of cholesterol rises in blood, it starts getting accumulated in the inner walls of the vessels. Not all the fats are bad. There are two main types of cholesterol, we will deal here. One is the good cholesterol, HDL and other is bad one, LDL. These are t he two major types of fats in which they move around in the body. LDL clogs the arteries and HDL actually works opposite to it and helps clearing the cholesterol from blood. The total cholesterol level should be less than 200 mg/dL. The LDL level should be below 100 mg/dL. In general, higher the LDL levels, more are the chances of getting cardiac diseases. The LDL is of low density, it tends to accumulate in the blood vessels instead of circulating in the blood. Over the time, this buildup of LDL causes the hardening of the arteries. The arteries narrow down and blood flow gets slow. The blood is therefore, unable to carry the nutrients to the heart and person suffers from the chest pain. As the plaque deposit grows, it can block the main artery, coronary artery, causing heart attack (Webmd.com, 2013).

The risk factors contributing to these deaths are obesity, poor diet, excessive alcohol intake and high lipid intake.
