Can coronary heart disease be cured?

Maybe: Coronary heart disease occurs when the arteries that feed the heart muscle are clogged with atherosclerotic plaque. A proper diet, control of blood pressure and diabetes, and statin and other medications to lower cholesterol can be used to slow the progression of coronary artery blockage. There is some evidence that exercise, diet and certain medications may cause blockage to regress.

Unknown: Although our ability to treat heart disease has drastically improved from stent technology, to bypass surgery to medications, CAD is rarely "curable." there is some animal data that drugs that raise HDL cetp modifying medications can help "regress" plaque in the coronaries. Preventive measures (primary and secondary) are most important, however.
