NEW YORK (R) – The heart of a smoker needs 15 years to fully heal after stopping smoking, a new study has shown.
Previous studies suggest that the risk of stroke in previous smokers stabilizes within five years, but a new study shows that it may take up to three times.
The study, to be presented next week at the American Heart Association, is the first of its kind in the analysis of end-of-treatment cases at advanced stages.
After analyzing 8,700 people over 50, Vanderbilt University researchers have found that the heart of smokers requires more than a decade to get rid of life-threatening harm, including nicotine, tobacco and countless other chemicals in cigarettes.

Meanwhile, Meredith Duncan, a doctor at Vanderbilt University Medical Center, said heart and blood vessels are the fastest recovery from the effects of smoking. The lungs are another story.
Duncan and her team in Nashville, Tennessee, wanted to explore how long the body needs to stop smoking to show real health effects.
Explore this team collected the data analyzed by the Framingham Heart Study, which began in 1948 and continued until 1975, involving two generations of people (almost half of whom were smokers).
The "Smoking" team was classified as people who smoked daily the equivalent of 20 years of cigarette packs. Smokers had a 70% risk of heart attack. After 5 years, the risk dropped by 38% after quitting smoking.
It took almost 16 years after treatment to bring the level of risk to cardiovascular disease back to normal.

In fact, blood vessels are the main benefit of quitting smoking. Just 20 minutes after the smoker stops smoking, the heart rate drops and the blood pressure returns to normal.
After 12 hours, the carbon monoxide level in the blood stabilizes, while the risk of heart attack decreases after about a week because the heart and blood vessels "release chemicals in cigarette smoke, making the plates more viscous.
"Even for bad smokers, the benefits of quitting smoking can not be overestimated," Duncan said.
Heart disease is the number one killer in every country in the world, including the United States and the United Kingdom, while rates increase due to obesity, stress, lack of exercise, and eating unhealthy food.
In recent years, some have turned to electronic cigarette smoking, a dubious and ill-considered practice where it has been proven that its damage to the human body is no different from ordinary cigarettes.
