Association Of Bleeding Avoidance Strategies with age-related bleeding and In-hospital mortality in patients undergoing percutaneous coronary Interventions.

BACKGROUND: The association of bleeding avoidance strategy (BAS) (consisting of a combination of radial access, bivalirudin [rather than heparin +/- glycoprotein GPIIb/IIIa antagonists], and/or vascular closure devices after femoral access) with bleeding and in-hospital outcomes has not been evaluated among elderly patients undergoing percutaneous coronary interventions (PCI). METHODS: We studied BAS use, bleeding and in-hospital mortality among 121,635 patients categorized by age (<50, 50-59, 60-69, 70-79, and ≥80years) undergoing PCI from the BMC2 registry (1/2010-12/2013). RESULTS: The use of BAS decreased marginally with age and despite improved utilization over time, remained lower among the elderly. BAS was used in a much lower risk cohort among all age groups. Nonetheless, compared with no BAS, the use of this strategy was associated with lower bleeding (adjusted OR 0.984, 95% CI 0.980-0.985) and in-hospital mortality (adjusted OR 0.996, 95% CI 0.994-0.997) among all age-groups. Similar relative reduction in the risk of bleeding was observed among all age groups with BAS use with lowest risk (thus greatest absolute risk reduction given their highest risk for bleeding) for the oldest cohort. CONCLUSIONS: BAS use decreased with age among patients undergoing PCI despite its association with lower in-hospital mortality. Although overall utilization improved over time, it still remained lower in the elderly cohort, a group likely to benefit most from it. These data identified an opportunity to design strategies to improve BAS use particularly among high-risk elderly patients undergoing PCI so as to decrease bleeding and reduce related adverse events and costs.
