How can smoking affect your heart?

ANSWER

The nicotine in cigarette smoke can damage your heart. It raises your blood pressure and heart rate, narrows your arteries and hardens their walls, and makes your blood more likely to clot. It stresses your heart and sets you up for a heart attack or stroke.

If you smoke, quit. Get help if you can’t do it on your own. Don’t smoke? Remember that secondhand smoke can still put you in harm’s way.
