A TIA also may signal an increased risk for a heart attack. Atherosclerosis, which is hardening of the arteries, affects blood vessels throughout the body, including arteries that supply blood to the heart and brain. If you have atherosclerosis in arteries to your brain, you may also have it in arteries to your heart (coronary artery disease). If you have coronary artery disease, you are at risk for a heart attack.
