The Performance of Risk Scores for Bleeding and Ischemia as Outcome Predictors in Acute Myocardial Infarction Patients with End-Stage Renal Disease.

Abstract

Background:

In patients with end-stage renal disease (ESRD), acute myocardial infarction (AMI) increases the risks of cardiovascular events, death, and bleeding. Several scores have been developed for predicting ischemic and bleeding outcomes in AMI patients, but none have been validated specifically for ESRD patients.

Objectives:

To compare and validate different risk scores as predictors of ischemic and bleeding outcomes in AMI patients with ESRD.

Methods:

This retrospective study enrolled 340 patients who had received percutaneous coronary intervention for AMI while undergoing maintenance hemodialysis for ESRD. Ischemic risk scores (TIMI-STEMI, TIMI-NSTEMI, GRACE, DAPT) and bleeding risk scores (PRECISE-DAPT, CRUSADE, ACUITY, ACTION, SWEDEHEART) were calculated. The ischemic outcome mainly focused on major adverse cardiovascular events (MACEs) within 14 days after hospitalization, and the bleeding outcome was 14-day major bleeding according to the CRUSADE criteria.

Results:

The GRACE score was superior in discriminating ischemic outcomes, especially in 14-day MACEs [area under curve (AUC) 0.791, p < 0.001]. None of the scores could ideally discriminate 14-day CRUSADE major bleeding, while the PRECISE- DAPT score had the best discriminative power (AUC 0.636, p < 0.001). Either GRACE score > 222 or PRECISE-DAPT score > 48 was associated with higher net adverse cardiovascular events (a composite of 14-day MACEs and 14-day CRUSADE major bleeding).

Conclusions:

In AMI patients with ESRD, the GRACE score can effectively discriminate the risk of short-term ischemic events. None of the scores could ideally discriminate the bleeding risk, but a high PRECISE-DAPT score still represented a higher rate of bleeding events.
