Over time, these plaques harden and narrow the artery, reducing blood flow to the heart, brain, or limbs. Smoking, high cholesterol, high blood pressure, diabetes, obesity, and lack of exercise speed up this buildup. When the blockage becomes severe or a plaque suddenly breaks and forms a clot, it can cause heart attack or stroke. . .
