Coronary Heart Disease

What it is:

Like any muscle, the heart needs a constant supply of oxygen and nutrients that are carried to it by the blood in the coronary arteries. When the coronary arteries become narrowed or clogged and cannot supply enough blood to the heart, the result is coronary heart disease.

If not enough oxygen-carrying blood reaches the heart, the heart may respond with pain called angina. When the blood supply is cut off completely, the result is a heart attack. The part of the heart that does not receive oxygen begins to die, and some of the heart muscle may be permanently damaged.

Who is at risk for Coronary Heart Disease?

Risk factors are conditions that increase your risk of developing heart disease. Some can be changed and some cannot.  Although these factors each increase the risk of coronary heart disease, they do not describe all the causes of coronary heart disease; even with none of these risk factors, you might still develop coronary heart disease.

Risk factors that can be controlled:

 High blood pressure
 High cholesterol
 Physical inactivity
* Although stress may increase your risk for coronary heart disease, it hasn't been scientifically proven.

Risk factors that can't be controlled:  family history of heart disease.
