Could peripheral vascular disease cause heart attack?

NO. Coronary artery disease can cause a heart attack, not peripheral vascular disease. "Peripheral" refers to the extremities (arms & legs), so PVD is blood vessel disease that affects the arms or legs (not the heart). Peripheral artery disease does increase the chances that the same individual may have coronary artery disease of the heart, so it is reasonable to screen PAD partients for heart dis.
Yes. Majority of heart attacks are from hardening of the vessels caused by plaque build-up which is related to htn, cholesterol, dm and family history.
