30-day readmissions after STEMI with cardiogenic shock 13%



Of patients with ST-elevation MI (STEMI) complicated by cardiogenic shock, 13% are readmitted within 30 days and remain in hospital for an average of 6 days, according to an analysis from the National Readmission Database presented at CRT 2019 sponsored by MedStar Heart & Vascular Institute.

“About one in four of the readmissions was for heart failure,” reported Karan Sud, MD, a cardiology resident at the Mount Sinai St. Luke’s West Hospital, New York.

Despite gains in acute survival among STEMI patients in cardiogenic shock, little attention has been paid to the risk of readmissions, according to Dr. Sud. According to data collected from the National Readmissions Database for 2010-2014, these rates are high enough to deserve attention, he said.

“Our goal is now to develop a scoring system based on our predictive model to identify patients at the index admission who are at risk for readmission,” Dr. Sud reported. On the basis of these predictors, it might be possible to implement strategies to optimize management and improve access to care.

In the years studied, there were 94,991 patients with STEMI and cardiogenic shock captured in the National Readmissions Database, of whom 43,205 survived and were followed for readmission. Of the 5,503 readmissions within 30 days, 12% were considered unplanned.

Half of the readmissions were for noncardiovascular causes, including sepsis, respiratory failure, and major bleeding. Of those related to cardiovascular disease, about half, or nearly 25% of the total, were for heart failure.

The predictors of readmission included female sex, age older than 75 years, average length of stay longer than 10 days, and more than three comorbidities, such as diabetes or chronic kidney disease, according to Dr. Sud.

“Those sent home from the index admission were more likely than those discharged to an extended care facility to be readmitted,” he added. He also noted that lower socioeconomic status was a risk factor for readmission, a phenomenon that he attributed to access issues regarding follow-up care.

“We are now conducting a prospective study to look at readmissions at 6 months,” reported Dr. Sud, who believes that efforts to understand the risk of readmission following STEMI complicated by cardiogenic shock might uncover opportunities for better management.
