Even mild heart failure increases mortality after day surgery

Heart failure with or without symptoms is associated with increased risks of mortality and complications in patients undergoing elective day surgery, a study suggests.
US researchers analysed data from more than 355,000 patients, mostly men, who underwent outpatient elective non-cardiac surgery from 2009 to 2016.
Outcomes were compared for the 5.5% of the group who had heart failure against the remainder who did not.
The heart failure group had nearly double the 90-day mortality after adjusting for confounders, such as age.
