Coronary artery disease affects millions of people worldwide, yet many don't realize they have it until a serious event occurs. The condition develops when plaque builds up inside the coronary arteries that supply blood to the heart muscle.
As these arteries narrow, blood flow decreases, and the heart doesn't receive enough oxygen. The danger lies in recognizing coronary artery disease symptoms early, before blocked arteries lead to a heart attack or other life-threatening complications.
