American researchers have found that smoking cessation can promote arterial health and reduce the risk of heart disease. "Smoking people" can see the effect after quitting smoking for one year.
The findings are published in the latest issue of the Journal of the American College of Cardiology.
One year of smoking cessation The University of Wisconsin-Madison School of Medicine and Public Health and the Research Center for Tobacco Research and Smoking Cessation jointly launched a smoking cessation study that requires more than 1,500 smokers to quit. Ways to quit smoking include the use of nicotine patches, nicotine mouth ingots, bupropion, simultaneous use of nicotine patches and buccal tablets, or a combination of bupropion and buccal tablets.
The Associated Press quoted cardiologist James Stein as saying on the 15th that a year later, 36% of the subjects successfully quit smoking.
Before the study began and one year later, the researchers measured the brachial vasodilation function (FMD) of the subjects. The researchers tightened the forearm of the study with a tourniquet and untied a few minutes while measuring with ultrasound. Brachial vasodilation is one of the main parameters for measuring the health of the brachial artery. It is closely related to the diastolic function of the heart and can predict the risk of cardiovascular disease.
Arterial improvement The comparison showed that after a year of smoking cessation, the brachial artery vasodilation function improved by 1%.
"The quitters have improved their vascular function despite their weight gain," said Stein. "This means that smoking cessation is good for vascular health and can reduce the risk of heart attack and cardiovascular disease."
Stein believes that 1% is a small number, but "this is a significant improvement, clinically significant", meaning that the risk of cardiovascular disease is reduced by 14%.
â€œA small step in improvement in a year,â€ Stan said. â€œThe question is, will the situation of these quitters get better and better?â€ The researchers plan to follow up for another two years and continue to observe the results.
Many people know that quitting smoking reduces the risk of lung cancer. And this is the first large clinical trial to prove that smoking cessation promotes arterial health.
Protecting the Heart In the study, successful smokers increased their body weight by an average of 4 kg, which is a common side effect of smoking cessation. â€œMany people are reluctant to quit because they are worried about weight gain,â€ Stan said.
In addition, the consequences of smoking cessation are good for your health, not only improve blood vessel function, but also increase high-density lipoprotein, the good cholesterol content in the blood. Good cholesterol helps prevent hardening of the blood vessels and is good for heart health.
Smoking is one of the main causes of heart disease. In the United States, about one-third of all deaths related to smoking die from heart disease.
Michael Fiori, director of the Center for Tobacco Research and Smoking Cessation at the University of Wisconsin, believes the results are exciting.
â€œThe results show new hopes for smokers who consider quitting smoking throughout the United States, and you can quickly improve cardiovascular health,â€ he said. Meditech Medical Network
