Smokers must wait 15 years after stopping for their heart disease and strokery to return to a normal level, a new study has found.
Previous studies indicate that earlier smokers stabilize in a stroke within five years, but new research shows that it may take three times.
The report, to be presented next week at the American Heart Association conference, is the first to investigate the connection in a live cohort.
After analyzing data of 8,700 people over the age of 50, researchers at Vanderbilt found that it takes well over a decade to smoke hearts to rid themselves of the life-threatening damage to nicotine, tobacco and the amount of other chemicals in cigarettes.
Unfortunately this is the good news. The heart and blood vessels are the fastest to recover from smoke damage, says author Meredith Duncan, a doctoral student at Vanderbilt University Medical Center. The lungs are another story altogether.
Heart disease is the leading killer in all countries of the world, including the United States and the United Kingdom, while prices rise (due to obesity, stress, lack of exercise and poor diet). The number of organs available for transplant is not.
Thankfully, one of the biggest risk factors ̵
1; cigarettes – is out of fashion since The Cigarette Papers was published in the early 1990s and revealed the actual damage they deliver.
Thus, the number of former smokers is on the rise, but we do not know much about the health risks (or lack of them) they face.
In recent years, some have turned to vaping – a dubious and investigated study that has shown the same chemical and addictive blows as combustible cigarettes.
Many, however, went cold turkey, for the most part to protect themselves and their loved ones from increased cancer, lung disease, heart disease and stroke.
Duncan and her team in Nashville, Tennessee, wanted to investigate how long it took for the decision to begin to show real health effects.
“There was no information about what actually happens to people in the long run based on estimates from carefully collected data,” Duncan told DailyMail.com.
To investigate, the group stored data from the Framingham Heart Study, which started in 1948 and went to 1975, including two generations of people, of which half were smokers.
Duncan’s team categorized “heavy smokers” as smokers corresponded to one package a day for 20 years. Heavy smokers accounted for 70 percent of the heart attacks in the study.
After five years, those who ended their risk fell 38 percent compared to those who had not stopped.
But it took 16 years after you quit cold turkey (not cut down) for the earlier smokers risk of cardiovascular disease to return to the level of never smoker.
“For people who have been smoking for many years, there may be changes in the heart and lungs that do not completely normalize,” explains Duncan.
“What is important to remember is that the actual risk of myocardial infarction and other forms of cardiovascular disease goes down, and this is an important discovery of our current study.”
It has actually been well documented that blood vessels enjoy the first benefits of quitting smoking.
Just 20 minutes after a person quit smoking, their heart rate and blood pressure drop to a normal level.
Twelve hours later, the carbon monoxide levels in their blood stabilize to an undetectable level.
About a week later, the risk of heart attack decreases, as the heart and blood vessels are no longer exposed to cigarette smoke chemicals that make platelets more tacky and cause unwanted blood clots, explains Duncan. 
“Even for heavy smokers, we can not exaggerate the benefits of quitting smoking,” said Duncan.
The next step for Duncan’s research is to look further at how lung cancer risk changes over time.
“We performed an analogue lung cancer trial as our result instead of [cardiovascular disease],” said Duncan.
“We would like to return to the subject, this time incorporating genetic data into our models to assess the interaction between genes and smoking habits at the risk of lung cancer.”
