ABSTRACT
OBJECTIVES: The influence of the bleeding site on long-term survival after the primary percutaneous coronary intervention (PCI) is poorly understood. This study sought to investigate the relationship between in-hospital access site versus non-access site bleeding and very late mortality in unselected patients treated with primary PCI. METHODS: Data of the 2715 consecutive patients with ST-segment elevation myocardial infarction treated with primary PCI, enrolled in a prospective registry of a high volume tertiary centre, were analysed. Bleeding events were assessed according to the Bleeding Academic Research Consortium (BARC) criteria. The primary outcome was 4-year mortality. RESULTS: The BARC type ≥2 bleeding occurred in 171 patients (6.3%). Access site bleeding occurred in 3.8%, and non-access site bleeding in 2.5% of patients. Four-year mortality was significantly higher for patients with bleeding (BARC type ≥2) than in patients without bleeding (BARC type 0+1), (36.3% vs 16.2%, p<0.001). Patients with non-access site bleeding had higher 4 year mortality (50.7% vs 26.5%, p=0.001). After multivariable adjustment, BARC type ≥2 bleeding was the independent predictor of 4 year mortality (HR 2.01; 95% CI 1.49 to 2.71, p<0.001). Patients with a non-access site bleeding were at 2-fold higher risk of very late mortality than patients with an access site bleeding (HR 2.62; 1.78 to 3.86, p<0.001 vs HR 1.57; 1.03 to 2.38, p=0.034). CONCLUSIONS: Both access and non-access site BARC type ≥2 bleeding is independently associated with a high risk of 4-year mortality after primary PCI. Patients with non-access site bleeding were at higher risk of late mortality than patients with access site bleeding.

OBJECTIVE: To investigate the relationship between inhospital bleeding as defined by Bleeding Academic Research Consortium (BARC) consensus classification and short-term and long-term mortality in unselected patients admitted for primary percutaneous coronary intervention (PCI). METHODS: We analysed data of all consecutive patients with ST segment elevation myocardial infarction (STEMI) admitted for primary PCI, enrolled in a prospective registry of a high volume centre. The BARC-defined bleeding events were reconstructed from the detailed, prospectively collected clinical data. The primary outcome was mortality at 1 year. RESULTS: Of the 1808 patients with STEMI admitted for primary PCI, 115 (6.4%) experienced a BARC type ≥2 bleeding. As the BARC bleeding severity worsened, there was a gradient of increasing rates of 1-year death. The 1-year mortality rate increased from 11.5% with BARC 0+1 type to 43.5% with BARC type 3b bleeding. After multivariable adjustment for demographic and clinical characteristics of patients, the independent predictors of 1-year death were BARC type 3a (HR 1.99; 95% CI 1.16 to 3.40, p=0.012) and BARC type 3b bleeding (HR 3.22; 95% CI 1.67 to 6.20, p<0.0001). CONCLUSIONS: The present study demonstrated that bleeding events defined according to the BARC classification hierarchically correlate with 1-year mortality after admission for primary PCI. The strongest predictor of 1-year mortality is the BARC type 3b bleeding.
