- Abstract: Objective To analyze the correlations of D-dimer and the Global Registry of Acute Coronary Events(GRACE)score with long-term heart failure(HF)in patients with acute myocardial infarction(AMI).Methods A total of 398 patients with AMI were selected as research objects and divided into normal D-dimer group(n=309)and elevated D-dimer group(n=89)based on the D-dimer level.Cox proportional hazard model was used to analyze the risk factors for long-term HF in both groups.Time-dependent receiver operating characteristic(ROC)curve was used to analyze the values of D-dimer,GRACE score and their combination in predicting long-term HF.According to the GRACE score and D-dimer level,398 patients were divided into low-value group(181 patients with normal D-dimerand low GRACE score),high-value group(70 patients with elevated D-dimer and high GRACE score),and middle-value group(147 patients did not meet the conditions of the low-value and high-value groups).Kaplan-Meier method was used to analyze the occurrence of long-term HF in the three groups.Point-biserial analysis was used to analyze the correlation between elevated D-dimer and the occurrence of long-term HF.Results The number of patients with long-term HF in the elevated D-dimer group was 2.3 times of the normal group.D-dimer and GRACE score were independent risk factors for long-term HF in patients with AMI(P＜0.05).Both D-dimer and GRACE score had certain predictive values for the occurrence of HF at 5 years after AMI,but the predictive efficiency of GRACE score was better.The incidence of long-term HF in the high-value group was significantly higher than that in the low-value group and the middle-value group(P＜0.01).D-dimer was signif-icantly positively correlated with the occurrence of long-term HF after AMI(P＜0.001).Conclu-sion Both D-dimer and GRACE score are independent risk factors for long-term HF in patients with AMI,and the two indexes have certain predictive value for the occurrence of long-term HF.Patients with both elevated indicators are high-risk groups for long-term HF.
