It may take fifteen years to gain back your heart health if you quit smoking now, finds a new study.
If you quit smoking now, it may take fifteen years for you to gain back those heart disease free days. To return to a nonsmoker level of heart disease risk, you need to stop smoking now, finds a new study. The findings of this study are to be //presented in Chicago at the American Heart Association's Scientific Sessions 2018. Cigarette smoking in the United States is on the decline, which means there are more former smokers. Studies to date suggest that the increased risk for cardiovascular disease in smokers diminishes a few years after quitting, but those studies have not been able to look as closely at smoking history, including changes in smoking habits such as variations in cigarettes smoked per day, or quitting followed by relapse to smoking.
‘It is going to take 15 years for a person's risk of heart disease to go down if he quits smoking now.’
In this study, researchers analyzed information, including lifetime smoking history, of nearly 8,700 participants of the Framingham Heart Study who were free of cardiovascular disease at the start of the study. The midpoint of follow-up among participants was 27 years, during which cardiovascular disease risk was compared among current, former and never smokers.Researchers found:
More than 70 percent of cardiovascular disease events in current or former smokers occurred among those who smoked at least 20 pack-years, which is the equivalent exposure of one pack a day for 20 years.
Former smokers who had quit within the last five years reduced their cardiovascular disease risk by 38 percent compared to those who continued to smoke.
It took 16 years since quitting for former smokers' risk of cardiovascular disease to return to the level of never smokers.
