A recent study indicates that it might take over 20 years for the likelihood of developing heart disease to return to normal levels following an individual’s decision to quit smoking.
For many years, specialists have been aware that inhaling cigarette smoke can lead to considerable harm to the heart.
At least 15,000 heart disease deaths in the UK are attributed to smoking every year, according to the British Heart Foundation.
Now, researchers in South Korea It has been determined that it takes an individual who has quit smoking approximately 25 years for their circulatory system to become similar to that of someone who has never smoked.
Furthermore, the research showed that heavy former smokers who have smoked for over eight years face a comparable risk of an imminent heart attack or stroke compared to individuals who continue smoking.
In the study As reported in the Journal JAMA, scientists analyzed health information from over 100,000 former smokers and more than 4 million individuals who had never smoked.
A decade following their cessation of smoking, the former smokers were checked on.
Other details were noted including age, how old they were when they started smoking, how many cigarettes they smoked a day and their age when they quit.
The research revealed that the connection between smoking and the increased risk of cardiovascular diseases followed a dose-dependent relationship, indicating that individuals who engaged in light smoking experienced a significant decrease in their risk fairly quickly upon quitting.
However, for long-term former smokers who had been smoking for at least eight years, the study determined that it might take up to 25 years before their risk of heart attack and stroke decreases to levels comparable to those of individuals who have never smoked.
According to the study’s authors, "Individuals with heavy smoking histories should be regarded as having a cardiovascular disease risk similar to those who currently smoke."
Each year, approximately 78,000 individuals in the UK lose their lives due to smoking-related causes, while numerous others suffer from various health issues linked to this habit.
Fifty percent of all tobacco-associated diseases in the UK involve cardiovascular issues, including heart conditions and strokes.
Many research papers have demonstrated that smoking is associated with heart failure—a condition where the heart muscle doesn’t circulate blood through the body effectively, often due to weakness or stiffness.
Consequently, the heart fails to deliver the necessary oxygen and essential nutrients to the body's organs and tissues for them to function properly.
The approximately 7,000 chemicals found in tobacco—including substances like tar—can harm the blood vessels supplying the heart. This vascular damage is believed to contribute significantly to the injury inflicted upon the organ by smoking.
In the meantime, nicotine—a potent additive present in tobacco—is strongly associated with perilous rises in both heart rate and blood pressure.
Cigarette smoke releases toxic gases like carbon monoxide into your system, thereby decreasing the amount of available oxygen even more.
Approximately one out of every eight British and American adults presently smokes cigarettes, whereas almost half of the adult population smoked back in the 1970s.
