Current smokers in the study had higher risk for heart attack, blood clots, pneumonia, and even death post-surgery compared to people who had never smoked and those who had stopped smoking.
“The adverse long-term effects of smoking are well known, but to have such effects in an acute setting like surgery had not been well elucidated,” according to senior author Dr. Faek Jamali of the American University of Beirut Medical Center in Lebanon.
These results add to the spectrum of the damaging effects of smoking, Jamali told Reuters Health by email.
