(HealthDay News) -- Most people realize that smoking causes cancer, but it can also wreak havoc on your heart, experts say.
The National Heart, Lung and Blood Institute says smoking:
- Damages blood cells, heart function and blood vessels
- Increases the risk of hardening of the arteries, which restricts blood flow.
- Increases the risks of heart disease, which occurs when plaque builds up in the arteries.
