Study in United States of America It turned out that the risk of cardiovascular disease ex-smokers takes more than 15 years old returning to the level of people who never smoked.
Studies that were presented at the American Heart Association's scientific sessions in Chicago suggest that the highest risk cardiovascular diseases it will decrease for smokers a few years after the withdrawal, although they have not been able to analyze the history of smoking, such as changes in smoking habits, daily intake of cigarettes or relapses.
In this scenario, experts analyzed the trajectory for 27 years 8,700 people without cardiovascular diseases, among which there were smokers, former smokers and others who had never smoked. Thus, they found that more than 70% of cardiovascular events in current or previous smokers were among those who smoked at least one package per day for 20 years.
In addition, scientists have shown that former smokers who had smoked over the last five years, reduced the risk of cardiovascular disease by 38 percent compared with those who continued to smoke.
"These findings focus on the benefits of cessation of smoking over a five-year period, as it reduces the risk of a heart attack, stroke or other cardiovascular disease by 38% compared with people who continue to smoke. However, we also found that the risk of cardiovascular disease in former smokers is still big to 16 years old compared to people who have never smoked, "said researchers.
