ABSTRACT

The impact of diabetes mellitus (DM) on clinical outcomes of acute ST-segment elevation myocardial infarction (STEMI) following fibrinolytic therapy remains uncertain. We queried the National Inpatient Sample (NIS) for STEMI patients who received fibrinolytic therapy. Categorical and continuous variables were compared using the unadjusted odds ratio (uOR) and t-test analysis, respectively. A binary logistic regression model was used to control the outcomes for patient demographics, procedural characteristics, and baseline comorbidities. A total of 111,155 (no-DM 84,146, DM 27,009) were included. The unadjusted odds of in-hospital mortality (8.4% vs. 6.8%, uOR 1.25, 95% CI 1.19–1.31, P = <0.0001) and cardiogenic shock (7.7% vs. 6.2%, uOR 1.26, 95% CI 1.20–1.33, P = <0.0001) were significantly higher in patients with DM compared to those with no DM, respectively. The odds for major bleeding and cardiopulmonary arrest were significantly lower for in diabetes. The adjusted pooled estimates mirrored the unadjusted findings. Diabetic patients receiving fibrinolytic therapy for STEMI might have higher odds of all-cause mortality and cardiogenic shock compared to non-diabetic patients.

Article Highlights

  • STEMI is one of the major causes of cardiovascular mortality and morbidity

  • PCI is the ideal choice for revascularization; however, fibrinolytics are needed if PCI cannot be performed.

  • Diabetic patients with STEMI receiving fibrinolytics have higher in-hospital mortality.

  • CS is more frequently seen in diabetics post fibrinolytic use compared to non-diabetic patients.

  • Fibrinolytic use in diabetics is associated with higher hospitalization cost and LOS.

  • Thrombolytic utilization has decreased over the years; however, mortality has trended up for diabetics with thrombolytic use.
