Health Tip: Smoking Affects Your Heart

It increases the risk of heart disease

(HealthDay News) -- Smoking can lead to cell and tissue damage throughout your body, and experts say your heart isn't spared.

The U.S. National Heart Lung and Blood Institute says smoking can:

  • Decrease the blood's ability to carry oxygen.
  • Force the heart to work harder by raising blood pressure and heart rate.
  • Raise triglycerides (fat) and bad cholesterol, while lowering good cholesterol.
  • Affect the heart's normal rhythm.
  • Narrow blood vessel walls.
  • Increase inflammation, which can lead to increased plaque buildup in blood vessels.
