Gender-Specific Predictive Markers of Poor Prognosis for Patients with Acute Myocardial Infarction During a 6-Month Follow-up

Mounting evidence indicates the impact of gender difference on the assessment, treatment, and outcome of patients with acute myocardial infarction (AMI). However, gender-specific prognostic markers of AMI are still lacking. The present study aimed to investigate gender-specific markers of poor prognosis (all-cause mortality or readmission) in a cohort of AMI patients followed up for 6 months. Compared with males (n = 157), females (n = 40) were older and more frequent with previous medical history of hypertension and diabetes mellitus. During the 6-month follow-up, BUN >= 7.73 mM, myoglobin >= 705.8 ng/mL, and Killip classification 2-4 were identified as the independent predictors of poor prognosis for male AMI patients, while D-dimer >= 0.43 mg/L as an independent predictor of poor prognosis in female AMI patients. In conclusion, our data suggest that prognostic markers for AMI patients may differ according to genders. Gender-specific prognostic markers may be useful to guide the risk stratification, clinical therapy, and medications for AMI patients.
