Abstract
Background and Aims
End-stage renal disease (ESRD) patients frequently have the coronary artery disease. However, the short- and long-term outcome of ESRD patients with acute myocardial infarction (AMI) is little known. The aim of this study was to clarify it.
Method
Using the database of the Osaka Acute Coronary Insufficiency Study (OACIS), 8702 consecutive AMI patients (male: 75.2%, mean age: 66.9±12.2yrs) from 2002 to 2013 were analyzed. We classified these patients into two groups, those with ESRD [ESRD group (n=271)] and without ESRD [No-ESRD group (n=8431)] and examined in-hospital or long-term all-cause mortality. ESRD was defined as eGFR<15ml/min/1.73m2.
Results
ESRD group had higher frequency of diabetes (59.3% vs 37.8%, p<0.01), hypertension (90.1% vs 63.3%, p<0.01), Killip class≧2 (40.1% vs 21%, p<0.01), multi-vessel disease (69.3% vs 50.8%, p<0.01), and lower frequency of peak CK>3000 (21.7% vs 32.4%, p<0.01) than No-ESRD group. Mean follow-up period was 1041±721 days. In hospital mortality of ESRD group was 27% and No-ESRD group 7.2%. In patients who discharged alive (8027 patients), 1-year mortality of ESRD group was 12.2% and No-ESRD group 3.3%, 3-year mortality of ESRD group was 29.3% and No-ESRD group 8.7%. Kaplan-Meier analysis revealed that the all-cause mortality (log-rank p<0.01) was significantly higher in ESRD group than No-ESRD group. In ESRD patients who discharged alive (203patients), Cox univariate analysis after multiple imputation revealed that peak CK>3000 was significantly associated with an increased risk of mortality (Hazard ratio 2.67, 95% confidence interval 1.18to 6.07, p=0.031).
Conclusion
In patients with AMI, ESRD was significantly associated with worse short- and long-term outcome, suggesting that careful treatment might be required in ESRD patients with AMI, especially had peak CK>3000.
