Readmissions, outcomes after perioperative AMI

By: Judy Mathias

Editor’s Note

In patients having noncardiac surgery who develop a perioperative acute myocardial infarction (AMI), about one in three died in-hospital or were readmitted within 30 days of discharge, finds this study presented March 10 at the 2018 American College of Cardiology Annual Scientific Session.

Among more than 3 million hospitalizations analyzed in the US Nationwide Readmission Database, researchers identified 8,085 patients with perioperative AMI. Of these, 1,135 (14.0%) died in-hospital. Survivors of AMI were more likely to be readmitted in 30 days than surgical patients without AMI (19.1% vs 6.5%).

Most common reasons for readmission were infectious complications (30.0%), cardiovascular complications (25.3%), and bleeding (10.4%). In-hospital mortality during readmission in the first 30 days was 11.3%. At 6 months, mortality risk was 17.6% and readmission was 36.2%.

The data suggest that mortality among perioperative AMI patients poses a significant burden to the healthcare system and there need to be strategies to improve outcomes in these patients, the authors say.
