Cardiovascular Disease & Smoking

How smoking cause heart Attack

Smoking increases the risk of  Cardiovascular disease.However, the magnitude of this increase in risk varies substantively according to a range of factors. Smoking-related CVD risks are highest in current and recent smokers, compared to never smokers and those who have quit in the more distant past . Risk also increases with increasing duration of use and with greater intensity of smoking, as measured by the number of cigarettes smoked per day

Current smoking increases the risk of virtually all CVD subtypes, at least doubling the risk of many, including AMI, cerebrovascular disease and heart failure. Paroxysmal tachycardia is a newly identified smoking-related risk. Where comparisons are possible, smoking-associated relative risks for fatal and non-fatal outcomes are similar. Quitting reduces the risk substantially. In an established smoking epidemic, with declining and low current smoking prevalence, smoking accounts for a substantial proportion of premature CVD events.

What makes cigarettes so toxic and dangerous?

There are more than 5,000 chemical components found in cigarette smoke and hundreds of them are harmful to human health, according to the Centers for Disease Control and Prevention.

Here are a few examples:

  • 1,3-Butadiene is a chemical used to manufacture rubber. It is considered to be a carcinogenic chemical that can cause certain blood cancers.
  • Arsenic is used to preserve wood. Some arsenic compounds have been linked to cancer of the lung, skin, liver, and bladder.
  • Benzene is used to manufacture other chemicals. It can cause cancer, particularly leukemia, in humans.
  • Cadmium is a metal used to make batteries. Cadmium and cadmium compounds can cause lung cancer and have been associated with kidney and prostate cancer.
  • Chromium VI is used to make alloy metals, paint and dyes. Chromium VI compounds cause lung cancer and have been associated with cancer of the nose and nasal sinuses.
  • Formaldehyde is used to make other chemicals and resins. It is also used as a preservative. Formaldehyde causes leukemia and cancer in respiratory tissues.
  • Polonium-210 is a radioactive element that has been shown to cause cancer in animals.
  • Tar is not one single chemical, instead it describes several chemicals that are in tobacco smoke. It leaves a sticky, brown residue on your lungs, teeth and fingernails.

How can I quit smoking?

If you have CAD or another form of cardiovascular disease, quitting smoking is the most important thing you can do to lower your chances of a heart attack or stroke.
