Prognostic value of access and non-access sites bleeding after percutaneous coronary intervention.

Little is known about the impact of bleeding site on mortality after percutaneous coronary intervention. The aim of this study was to assess the impact of access and non-access site bleeding within 30 days after percutaneous coronary intervention on mortality.This study represents a pooled patient-level analysis of 14 180 patients recruited in 7 randomized trials. Access and non-access site bleeding were assessed using the Bleeding Academic Research Consortium criteria. The primary outcome was 1-year mortality. Follow-up was complete in 97.5% of the patients. There were 414 deaths within the first year after percutaneous coronary intervention: 44 deaths among patients with access site bleeding, 60 deaths among patients with non-access site bleeding, and 310 deaths among patients without bleeding (Kaplan-Meier estimates of mortality, 4.5%, 10.0%, and 2.5%, respectively; adjusted hazard ratio, 1.72 [95% confidence interval, 1.19-2.47] for access site bleeding versus no bleeding; hazard ratio, 2.78 [2.00-3.86] for non-access site versus no bleeding). The inclusion of non-access site bleeding (the absolute and relative integrated discrimination improvement, 0.005 and 8.9%; P=0.031) but not of access site bleeding (the absolute and relative integrated discrimination improvement, 0.0015 and 2.7%; P=0.084) was associated with an improvement of the discriminatory power of multivariable model for mortality prediction.Both access and non-access site bleeding events occurring within 30 days of a percutaneous coronary intervention are independently associated with an increased risk of 1-year mortality. Non-access site bleeding is a stronger correlate of mortality than access site bleeding, and it improves the discriminatory power of models for mortality prediction.     «
