It took more than 15 years for those who quit to smoke for their risk of heart disease to return to that of those who had never smoked. This is evidenced by the results of preliminary studies presented recently in Chicago at the Scientific Sessions of the American Heart Association.

Previous studies have shown that smokers' risk of cardiovascular disease decreases several years after they quit smoking. However, it was not previously possible to trace the smoking history of participants, to note changes in smoking frequency or evidence of smoking relapse.

In the new study, the researchers analyzed the lifelong smoking history of about 8,700 participants in the Framingham Heart Study who did not have cardiovascular disease at the start of the study. On average, study participants were followed for 27 years. At the same time, the researchers compared the risk of cardiovascular disease in non-smokers and former smokers.

As a result, the researchers found that:

More than 70% of cases of cardiovascular disease in smokers or ex-smokers have developed in those who smoked a pack a day for 20 years.

  • For ex-smokers who quit within the past five years, the risk of developing cardiovascular disease decreased by 38% compared to those who continued to smoke.
  • Overall, it took 16 years since quitting smoking for the risk of cardiovascular disease in former smokers to return to the same level as in those who never smoked.

“These results underscore that some benefit from quitting smoking can be seen already in the first five years, with 38% lower risk of heart attack and stroke compared to people who continue to smoke. We also found that the risk of cardiovascular disease remained increased for 16 years after a person quit smoking, compared to people who never smoked. The conclusion of the study is that if you smoke, now is the right time to quit,”says Meredith Duncan, study author at the Vanderbilt University Medical Center in Nashville, Tennessee.
