The Patterns of non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) bleeding risk score has been proposed to predict the risk of bleeding events after percutaneous coronary intervention (PCI). However, the prognostic value of the PARIS bleeding risk score for long term all-cause mortality, cardiac mortality and hospitalization due to heart failure has not yet been evaluated. Therefore, the aim of the present study was to evaluate the prognostic value of the PARIS bleeding risk score for all-cause and cardiac mortalities and hospitalization due to heart failure after PCI. Consecutive 1061 patients who had undergone PCI were divided into 3 groups based on the PARIS bleeding risk score; low (n = 112), intermediate (n = 419) and high-risk groups (n = 530). We prospectively followed up the 3 groups for all-cause and cardiac mortalities and hospitalization due to heart failure. Kaplan-Meier analysis revealed that all of the outcomes were highest in the high-risk group among the 3 groups (P < 0.001, P < 0.001 and P < 0.001 respectively). Multivariable Cox proportional hazard analysis, adjusted for confounding factors, revealed that all-cause mortality of the intermediate or high-risk groups was higher than those of the low-risk group (adjusted hazard ratio 6.06 and 12.50, P = 0.013 and P < 0.001, respectively). The PARIS bleeding risk score is a significant indicator of prognosis for all-cause mortality in patients after PCI.
