How does coronary artery disease develop?

Coronary artery disease (CAD) occurs when atherosclerotic plaque (hardening of the arteries) builds up in the wall of the arteries that supply the heart. This plaque is primarily made of cholesterol. Plaque accumulation can be accelerated by smoking, high blood pressure, elevated cholesterol, and diabetes. Patients are also at higher risk for plaque development if they are older (greater than 45 years for men and 55 years for women), or if they have a positive family history for early heart artery disease.

The atherosclerotic process causes significant narrowing in one or more coronary arteries. When coronary arteries narrow more than 50 to 70%, the blood supply beyond the plaque becomes inadequate to meet the increased oxygen demand during exercise. The heart muscle in the territory of these arteries becomes starved of oxygen (ischemic). Patients often experience chest pain (angina) when the blood oxygen supply cannot keep up with demand. Up to 25% of patients experience no chest pain at all despite documented lack of adequate blood and oxygen supply. These patients have "silent" angina, and have the same risk of heart attack as those with angina.

When a blood clot (thrombus) forms on top of this plaque, the artery becomes completely blocked causing a heart attack.

When arteries are narrowed in excess of 90 to 99%, patients often have accelerated angina or angina at rest (unstable angina). Unstable angina can also occur due to intermittent blockage of an artery by a thrombus that eventually is dissolved by the body's own protective clot-dissolving system.

After years of suffering I found that simply getting my yeast under control with garlic and some other over the counter items worked. A topical is needed to help keep the skin soft also. Keep in mind that the lymphatic system uses the skin pores as an exit point for ridding the body of toxins so you may want to look into a detoxification program to get your system in better shape to help control your eczema.

Having a triple coronary artery bypass graft in 2011, I finally realized that stress in my job and the scary situations I experienced was the number one cause of heart disease, let alone smoking, which I think the number 3 cause. Ignoring blood pressure high was number 4. Now I have swelling in my feet, diuretic works good, but I feel chest pain from time to time.
