15 years to recover the heart of the smoker after the start


Tomorrow – A new study showed that the heart of a smoker needs 15 years to recover completely after quitting.

Previous research suggests that the risk of stroke in previous smokers stabilizes over five years, but a new study shows that it can take up to 3 times more time.

The study, which will be presented next week at the American Heart Association conference, is the first of its kind in the analysis of throwing cases at an advanced stage.

After analyzing 8,700 people in 50 years, researchers at Vanderbilt University found that smokers' hearts need more than a decade to get rid of life-threatening damage, including nicotine, tobacco and countless other chemicals in cigarettes.

At the same time, Meredith Duncan, a PhD student at the Vanderbilt University Medical Center, said that the heart and blood vessels regenerate the most quickly after the effects of smoking.

Duncan and her team in Nashville, Tennessee wanted to study how long the body had to quit smoking to show real health effects.

To explore, the team collected data analyzed by the Framingham Heart Study, which began in 1948 and lasted until 1975, involving two generations of people (almost half of them smokers).

The team "Smokers" was classified as people who smoked the equivalent of a pack of cigarettes a day for 20 years. Smokers had a 70% risk of a heart attack, after 5 years the risk fell by 38% after quitting.

But almost 16 years after quitting treatment, the return of the risk level of cardiovascular disease to normal.

In fact, blood vessels are the main benefit of quitting, and 20 minutes after the smoker quits smoking, heart rate drops and blood pressure return to normal.

After 12 hours, the level of carbon monoxide in the blood will stabilize, and the risk of a heart attack decreases after about a week because the heart and blood vessels "get rid of chemicals from cigarette smoke that make the tiles more sticky,.

"Even for the bad smokers, the benefits of quitting can not be overestimated," said Duncan.

Heart disease is the largest killer in every country in the world, including the United States and the United Kingdom, and rates are rising due to obesity, stress, lack of exercise and eating unhealthy meals.

In recent years, some have turned to electronic smoking, a dubious and ill-conceived practice in which it has been proven that the damage done to the human body is not different from the usual cigarette damage.
