How much heart and lung do you need to get rid of smoking?
A new study has to wait 15 years for ex-smokers to quit smoking to normalize the risk of heart disease and heart attack.
Some previous studies have shown that the risk of infarction is stable about five years after quitting smoking, but a new study shows that it takes three times more time.
After analyzing the data of 8,500 people for 50 years, researchers from Vanderbilt have found that it has been necessary for more than a decade to eliminate the damage caused by nicotine and various other chemicals in the cigarette.
The heart and blood vessels will heal faster than the harm caused by cigarettes, says author Duncan Duncan. But according to the lung, there's a very different story, so they need to be rescued in a longer time.
One of the main contributors to cardiovascular disease, which is the number one killer in all countries in the world, is cigarette. Perhaps this is why more people decide to quit smoking, and although this is wonderful, it does not mean that their health will be better immediately.
Bilgi People who have been smoking for a long time have a lack of information about what really happened,. Writes Duncan.
To investigate this, they received data from a study that began in 1948 and lasted until 1975, when two generations of people attended and nearly half smoked.
As heavy smokers, they have classified people who drink at least one pack a day for 20 years and about 70 percent of them have had a heart attack during the study.
Five years later, those who stopped breathing had an infarction risk of 38 percent less than those who continued smoking.
16 years after she stopped smoking, she took smokers to return the cardiovascular health to the health of non-smokers.
De For people who have been smoking heavily for a long time, changes in the heart and lungs that cannot completely return to normal, “says Duncan. Ana The important thing to remember is that the risk of heart attack and other cardiovascular diseases is definitely reduced after quitting smoking, and this is the main discovery of this study “.
Indeed, some of the good effects of smoking cessation have been proven to be felt in the body immediately.
Only 20 minutes after the last cigarette is closed, the heartbeat and blood vessel pressure return to normal.
After about 12 hours, the carbon monoxide level drops to such a small level that it is almost impossible to detect it in the body.
One week later, the risk of infarct is much lower as the heart and blood vessels are no longer exposed to chemicals that can cause blood clots.
However, the risk of heart disease persists, but therefore, all good effects of smoking cessation should not be ignored.
