Smoking is the leading preventable cause of illness and death in the U.S.

The #1 thing you can do to keep your heart and vascular system healthy and to prevent complications is to refrain from tobacco use. Yes, quitting smoking is that important.

Smoking is the leading preventable cause of illness and death in the United States and is known to affect all systems of your body. Smoking is also the primary cause of cardiovascular diseases, such as heart disease, stroke and peripheral artery disease (PAD).

All forms of tobacco, including cigarettes, contain nicotine, which is a highly addictive drug that constricts blood vessels and thus increases blood pressure and heart rate. This can lead to atherosclerosis, a thickening and hardening of the arteries caused by cholesterol and lipid deposits, which puts your heart and circulatory system at great risk. At least 63 cancer-causing chemicals have been found in tobacco as well, further harming your body.

What to avoid

Tobacco products include:

  • Cigars
  • Cigarettes
  • Chew
  • Dip
  • Snuff

Avoiding secondhand smoke and vaping is important, as well.

Quitting smoking can be difficult, but we know you can do it, and we are here to help

The first step to a healthier, non-smoking you is to talk to your cardiologist about quitting smoking and making other heart-healthy lifestyle changes today. Quitting can be difficult. You may attempt to quit many times before you can successfully stop smoking permanently. Many smokers may use many methods to quit smoking; quitting may require a combination of the different methods. However, we know you can do it, and we are here to help you give up smoking for good.

Some of the ways that people quit smoking include:

  • Cold turkey
  • Using nicotine-replacement therapy, such as gum or a patch
  • Taking medications, such as Chantix
  • Joining a support group or stress management program
  • Calling a quitline or joining an online support group
  • Combination therapy—taking both anti-depressant medication and nicotine replacement therapy

Quit-smoking products can lessen your urge to smoke. Most replace nicotine for a while, and all help ease you off your addiction, increasing your chances for quitting smoking for good.

These products are not for everyone. Never smoke and use a nicotine substitute at the same time, because you could overdose on nicotine.
