The Importance of Validating Bleeding Risk Scores in End-Stage Renal Disease Patients Undergoing Dialysis After Acute Myocardial Infarction

The risk of bleeding is a significant concern for end-stage renal disease (ESRD) patients undergoing dialysis after experiencing an acute myocardial infarction (AMI). ESRD patients are at a higher risk of bleeding due to their compromised kidney function, which can lead to impaired platelet function and increased bleeding tendency. Furthermore, the use of dual antiplatelet therapy (DAPT) in these patients can also increase the risk of bleeding.

Several scoring systems have been developed to predict the risk of bleeding complications in patients undergoing stent implantation and subsequent DAPT. These scores include Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT), Can Rapid Risk Stratification of Unstable Angina Patients Suppress ADverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE), Acute Catheterization and Urgent Intervention Triage strategY and Harmonizing Outcomes with RevasculariZatiON and Stents in Acute Myocardial Infarction (ACUITY-HORIZONS), and Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) score.

However, the use of these scores in ESRD patients undergoing dialysis after AMI has not been well-studied. A recent Taiwanese study reported that the 2-year gastrointestinal bleeding risk in CKD patients undergoing maintenance dialysis was 1.5 times higher than that in patients without CKD and slightly higher than that in CKD patients who do not require dialysis.

Therefore, validating existing bleeding risk scoring systems in ESRD patients undergoing dialysis after AMI is crucial to better understand the risk of bleeding complications in this population. This can help healthcare providers to develop more effective strategies for reducing the risk of bleeding and improving patient outcomes.

In conclusion, the risk of bleeding is a significant concern for ESRD patients undergoing dialysis after experiencing an acute myocardial infarction. Validating existing bleeding risk scoring systems in this population is crucial to better understand the risk of bleeding complications and develop more effective strategies for reducing the risk of bleeding and improving patient outcomes.
