Smokers are likely to have thicker heart walls and reduced pumping function, compared with nonsmokers and former smokers.

‘Smoking causes thickening of the heart wall and reduce heart function, leading to a higher risk of heart failure, even in people who don't have heart attacks.’

"These data suggest that smoking can independently lead to thickening of the heart and worsen of heart function, which may lead to a higher risk of heart failure, even in people who don't have heart attacks," said Wilson Nadruz Jr, M.D., Ph.D., lead author of the study and research fellow at Brigham and Women's Hospital in Boston, Massachusetts.![twitter](https://images.medindia.net/icons/news/social/twitter.png)

"In addition, the more people smoke, the greater the damage to the heart's structure and function, which reinforces the recommendations stating that smoking is dangerous and should be stopped."
The study examined data from 4,580 participants in the Atherosclerosis Risk in Communities (ARIC) Study who underwent an echocardiogram. Even after accounting for factors such as age, race, body mass index, blood pressure, diabetes and alcohol consumption, current smokers had thicker heart walls and reduced pumping function, compared with nonsmokers and former smokers.
"The good news is that former smokers had similar heart structure and function compared with never smokers," said Scott Solomon, M.D., senior study author and professor of medicine at Harvard Medical School and Brigham and Women's Hospital. "This suggests that the potential effects of tobacco on the myocardium might be reversible after smoking cessation."
