Hospital Readmission After Perioperative Acute Myocardial Infarction Associated With Noncardiac Surgery.

ABSTRACT: BACKGROUND:Acute myocardial infarction (AMI) is a major cardiovascular complication of noncardiac surgery. We aimed to evaluate the frequency, causes, and outcomes of 30-day hospital readmission after perioperative AMI. METHODS:Patients who were diagnosed with AMI during hospitalization for major noncardiac surgery were identified using the 2014 US Nationwide Readmission Database. Rates, causes, and costs of 30-day readmissions after noncardiac surgery with and without perioperative AMI were identified. RESULTS:Among 3?807?357 hospitalizations for major noncardiac surgery, 8085 patients with perioperative AMI were identified. A total of 1135 patients (14.0%) with perioperative AMI died in-hospital during the index admission. Survivors of perioperative AMI were more likely to be readmitted within 30 days than surgical patients without perioperative AMI (19.1% versus 6.5%, P<0.001). The most common indications for 30-day rehospitalization were management of infectious complications (30.0%), cardiovascular complications (25.3%), and bleeding (10.4%). In-hospital mortality during hospital readmission in the first 30 days after perioperative AMI was 11.3%. At 6 months, the risk of death was 17.6% and ?1 hospital readmission was 36.2%. CONCLUSIONS:Among patients undergoing noncardiac surgery who develop a perioperative MI, ?1 in 3 suffer from in-hospital death or hospital readmission in the first 30 days after discharge. Strategies to improve outcomes of surgical patients early after perioperative AMI are warranted.
