Postop A-Fib may increase risk of hospitalization for heart failure

THURSDAY, July 14, 2022 (HealthDay News) — Postoperative atrial fibrillation (AF) is associated with incident hospitalization for heart failure in patients without a history of heart failure undergoing cardiac or non-cardiac surgery, according to a study published online on 28 june in the European journal of the heart.

Parag Goyal, MD, of Weill Cornell Medicine in New York, and colleagues examined the association between postoperative AF and incident hospitalization for heart failure in patients undergoing cardiac (76,536) and non-cardiac (about 2 .9 million).

The researchers found that among patients who underwent cardiac surgery, 18.8% developed incident postoperative AF compared with 0.8% of patients who underwent non-cardiac surgery. Postoperative AF was associated with incident hospitalization for heart failure for both people undergoing cardiac surgery (relative risk, 1.33) and those undergoing non-cardiac surgery (relative risk, 2.02). Postoperative AF remained associated with incident hospitalization for heart failure when excluding heart failure within one year after surgery (hazard ratios, 1.15 and 1.49 for cardiac surgery and non-cardiac surgery, respectively ).

“These results reinforce the adverse prognostic impact of postoperative AF and suggest that postoperative AF may be a marker for identifying patients with subclinical heart failure and those at high risk for heart failure,” the authors write.

Several authors disclosed financial ties to medical and pharmaceutical companies.
