Cholesterol is really a blood fat required by the human body in reasonable amounts. But, high cholesterol( levels can result in atherosclerosis and coronary artery disease (CAD). Angina is chest pain caused by the limitation of blood flow to the heart (cardiac ischemia). Nitrates can be utilized to relieve angina. 

A lot of people may have cholesterol blood tests often, including triglycerides, HDL ( LDL and total cholesterol. Means of increasing good cholesterol or lowering cholesterol levels ( cholesterol NNP be included by NNP reducing drugs, such as statins, fibrates, niacin (nicotinic acid) and bile acid resins. Nevertheless, these drugs do not slow calcification. A heart attack does occur if the coronary arteries become blocked. Cholesterol has several kinds. Both big parts are named LDL (low-density lipoprotein) and HDL (high-density lipoprotein). And simplistically, we discuss the LDL being the bad cholesterol and the HDL being the good cholesterol. 

That means that the bad cholesterol tends to amass in the arteries, tends to form plaques, tends to function as precursor to what eventually could end up being fully a coronary attack. 

The great cholesterol actually operates partly in reversing the cholesterol transport, requires cholesterol out of the plaque in the artery and might reunite it to the blood circulation, to the liver, to be excreted. So these are the 2 major categories, but within every one there are different particles, different cholesterols, different lipoproteins that carry the cholesterol, and they're differentially tough people.

Some of the LDL cholesterol, i.e., the bad cholesterol, is worse than the others. And it is often the small particle size that's very heavy. You can think about the cholesterol particles as marbles, perhaps, the little heavy ones, and the larger, brighter ones might be ping-pong balls. And so the small marble ones tend to be more dangerous. 

On one other side, HDL the nice cholesterol, possesses some elements which can be much better than others. Therefore cholesterol is quite an intricate issue, and we are developing more and more solutions that aim not only at the total cholesterol, in transforming the great and the poor.
