Heart disease is an umbrella term for a number of different diseases affecting the heart. As of 2007, it is the leading cause of death in the United States, England, Canada and Wales, killing one person every 34 seconds in the United States alone.
The blood vessels consist of arteries, arterioles, capillaries, venules, and veins. All blood is carried in these vessels. The arteries, which are strong, flexible, and resilient, carry blood away from the heart and bear the highest blood pressures. Because arteries are elastic, they narrow (recoil) passively when the heart is relaxing between beats and thus help maintain blood pressure. The arteries branch into smaller and smaller vessels, eventually becoming very small vessels called arterioles. Arteries and arterioles have muscular walls that can adjust their diameter to increase or decrease blood flow to a particular part of the body.

Are High Levels of Blood Cholesterol Hereditary?  

So another piece of the puzzle slipped into place. It was not just rabbits who died are of high blood cholesterol levels. People do. Other researchers are looking further back in time found that there was rationing during World War II in Norway and the United Kingdom was introduced, and in both countries fell, the rate of heart disease. (Although the rate of increase with bombs falling on my head rapidly, which might have had something to do with a quick change in causes of death.)

It was then decided that some people with a genetic predisposition known as familial hypercholesterolaemia (FH), basically an inherited disease, high blood cholesterol (LDL). Children inherit the condition from both parents could not be older than five of heart disease. Damn it, everything was already closed openand look like a case. Leap forward slightly in time, discovered in the 1970s, Brown and Goldstein, by the people with FH have a problem with their production of LDL receptors had. With fewer LDL receptors, the LDL level is increased and this was the basic "fault" in FH, which indicate how well, should actually called "hyper-low density lipoproteinemia.

It was at this point that the concept fragment from an elevated blood cholesterol levels began in a constellation of different lipoproteins, LDL, and was a "finger bad" cholesterol .. And so it seemed, although I'm jumping a little in time and space that all the pieces of the puzzle fell into place to replace. and the diet-heart hypothesis was really flying. As early as 1956 by the American Heart Association (AHA), a little premature in my opinion, the concept of "prudent diet" was started.

A prudent diet was butter and margarine, beef Chicken without skin, bacon and eggs and cold cereal, hot baths and cold showers, chocolate was a slap on the back of the neck with a cold truck. In the 1960s and 1970s, large studies were set up on dietary modification. The biggest probably the MR FIT study, where hundreds of thousands of people. What were the results of this study? "I think it would make things to tell you that at this point, all later revealed spoil.
