Prediabetes versus type 2 diabetes mellitus based on pre-percutaneous coronary intervention thrombolysis in myocardial infarction flow grade in patients with ST-segment elevation myocardial infarction after successful newer-generation drug-eluting stent implantation.


ABSTRACT:

Background

We compared the 2-year clinical outcomes between prediabetes and type 2 diabetes mellitus (T2DM) according to the pre-percutaneous coronary intervention (PCI) thrombolysis in myocardial infarction (TIMI) flow grade in patients with ST-segment elevation myocardial infarction.

Methods

Overall, 6448 STEMI patients were divided into two groups: pre-PCI TIMI 0/1 group (n = 4854) and pre-PCI TIMI 2/3 group (n = 1594). They were further divided into patients with normoglycemia, prediabetes, and T2DM. The major endpoint was major adverse cardiac events (MACEs), defined as all-cause death, recurrent myocardial infarction, or any repeat revascularization.

Results

In the pre-PCI TIMI 0/1 group, all-cause death rate was higher in both prediabetes (adjusted hazard ratio [aHR]: 1.633, p = 0.045) and T2DM (aHR: 2.064, p = 0.002) groups than in the normoglycemia group. In the pre-PCI TIMI 2/3 group, any repeat revascularization rate was also higher in both prediabetes (aHR: 2.511, p = 0.039) and T2DM (aHR: 3.156, p = 0.009) than normoglycemia. In each group (pre-PCI TIMI 0/1 or 2/3), the MACEs and all other clinical outcomes rates were similar between the prediabetes and T2DM groups.

Conclusions

Prediabetes showed comparable worse clinical outcomes to those of T2DM regardless of the pre-PCI TIMI flow grade.
