A new research published in the American Heart Association journal Circulation says three major types of smoking cessation therapies don't increase the risk of heart attack, stroke or heart-related death.
In recent years, there has been concern that some smoking cessation products may have serious cardiovascular risks.But in the largest analysis of side effects (63 clinical trials and 30,508 people), serious heart events didn't increase with nicotine replacement gums and patches or the nicotine addiction treatment varenicline (Chantix), and the antidepressant bupropion (Wellbutrin) protected against serious heart events.
"Undoubtedly, the benefits of quitting smoking outweigh any potential risks from smoking cessation therapies," said Edward J. Mills, Ph.D., M.Sc., study co-author and associate professor of medicine at Stanford University and Canada Research Chair at the University of Ottawa. Smoking cessation is associated with improved cardiovascular health, increased life expectancy, improved quality of life and reduced healthcare costs for smoking-associated conditions. Nicotine replacement therapy via patch or gum increased the risk of minor heart symptoms such as a rapid or irregular heartbeat, researchers said.
