Abstract

AIMS:

The aim of this study was to assess the impact of bleeding after percutaneous coronary intervention (PCI) on the outcome of patients with type 2 diabetes.

METHODS AND RESULTS:

This study included 4,329 diabetic patients who underwent PCI. Bleeding was assessed using the Bleeding Academic Research Consortium criteria. The primary outcome was one-year mortality. Bleeding events occurred in 474 patients (10.9%). Access-site and non-access-site bleeds occurred in 274 patients (58%) and 200 patients (42%), respectively. Within the first year after PCI there were 198 deaths: 45 deaths (9.6%) among patients with bleeding and 153 deaths (4.0%) among patients without bleeding (adjusted hazard ratio=2.04 [95% confidence interval 1.38-3.00], p<0.001). There were 25 deaths (12.7%) among patients with non-access-site bleeding and 20 deaths (7.4%) among patients with access-site bleeding (odds ratio [OR]=3.45 [2.20-5.41], p<0.001 for non-access-site bleeding vs. no bleeding and OR=1.90 [1.17-3.01], p=0.008 for access-site bleeding vs. no bleeding). Bleeding improved the discriminatory power of the multivariable model for mortality prediction (p=0.002).

CONCLUSIONS:

In patients with diabetes undergoing PCI, occurrence of bleeding within the first 30 days after PCI was associated with a significant increase in the risk of one-year mortality.
