Multicenter StudyA therapeutic window for platelet reactivity for patients undergoing elective percutaneous coronary intervention: results of the ARMYDA-PROVE (Antiplatelet therapy for Reduction of MYocardial Damage during Angioplasty-Platelet Reactivity for Outcome Validation Effort) study.
This study sought to validate the ability of the VerifyNow P2Y12 assay (Accumetrics, San Diego, California) in predicting both ischemic and bleeding events after elective percutaneous coronary intervention (PCI). ⋯ A therapeutic window for platelet reactivity measured with the VerifyNow P2Y12 assay can be identified using specific thresholds that define a group of patients at lower risk for both ischemic and bleeding events. Adjunctive measures may be beneficial in patients with higher or lower platelet reactivity in order to improve clinical outcomes after PCI.

Comparative StudyDifferent prognostic significance of high on-treatment platelet reactivity as assessed by the VerifyNow P2Y12 assay after coronary stenting in patients with and without acute myocardial infarction.
This study compared the prognostic role of high on-treatment platelet reactivity (HTPR) in predicting thrombotic events in a Korean population undergoing percutaneous coronary intervention (PCI) in the acute myocardial infarction (AMI) and non-AMI setting. ⋯ Increased residual platelet reactivity is related to post-discharge CV events in subjects with AMI, whereas the prognostic significance of HTPR seems to be attenuated in patients with stable coronary disease after PCI.

Incidence of overall bleeding in patients treated with intra-aortic balloon pump during percutaneous coronary intervention: 12-year Milan experience.
This study aims to report a "real-world" experience of in hospital complications and clinical outcome of a large cohort of consecutive patients who underwent percutaneous coronary intervention (PCI) with intra-aortic balloon pump counterpulsation (IABP) support, from a tertiary care center over a 12-year period. ⋯ Bleeding related to the IABP access site was significantly higher in the Urgent group and accounted for more than two-thirds of overall access site-related bleeding. IABP treatment duration and renal impairment were independent predictors of overall bleeding.
