Tomorrow – A new study found that a smoker's heart needed 15 years to fully recover after quitting.
Previous studies suggest that the risk of stroke in previous smokers stabilizes within five years, but the new study shows that it can be multiplied by three.
The study, which will be presented next week at the conference of the American Heart Association, is the first of its kind in the analysis of smoking cessation cases during advanced stages.
After analyzing 8,700 people over the age of 50, researchers at Vanderbilt University discovered that it took more than a decade for smokers' hearts to rid themselves of life-threatening damage. including nicotine, tobacco and countless other chemicals found in cigarettes.
At the same time, Meredith Duncan, a doctoral student at the Vanderbilt University Medical Center, said that the heart and blood vessels were the fastest to heal the effects of smoking, as well as the lungs.
Duncan and his team in Nashville, Tenn., Wanted to explore how long it takes for the body to quit smoking to show the real health effects.
To investigate, the team gathered data analyzed by the Framingham Heart Study, which began in 1948 and continued until 1975 and that involved two generations of people (almost half of them were smokers).
The "smoker" team was ranked among people who smoked the equivalent of a pack of cigarettes a day for 20 years. Smokers were 70% at risk for a heart attack, but 38% later, after 5 years, they quit.
But it took nearly 16 years after stopping smoking to bring the risk of cardiovascular disease back to normal.
In fact, blood vessels are the main benefit of stopping smoking: only 20 minutes after the smoker has quit smoking, heart rate drops and blood pressure returns to normal.
After 12 hours, the levels of carbon monoxide in the blood stabilize and the risk of heart attack decreases after about a week because the heart and blood vessels "remove the chemicals in the cigarette smoke which make the plates more viscous,.
"Even for bad smokers, the benefits of quitting can not be overestimated," Duncan said.
Heart disease is the leading cause of death in every country in the world, including the United States and Britain, while rates are rising due to obesity, stress, lack of blood pressure, high blood pressure, high blood pressure, and high blood pressure. exercise and unhealthy meals.
In recent years, some have turned to e-cigarettes, a questionable and inconsiderate practice in which it has been proven that its harmful effects on the human body are no different from the damage caused by smoking.
