Background: MACE and bleeding complications are strongly associated with subsequent mortality in AMI pts treated with anticoagulant and antiplatelet therapies. The relative impact of MACE and bleeding on overall mortality in AMI is not well understood.Objectives and Methods: We sought to assess the relative impact of MACEand major bleeding events on mortality in 3,602 pts with STEMI undergoing primary PCI in the HORIZONS-AMI trial.

Continuation or interruption of OAC was decided for each case by the medical team before performing PCI. We collected initial parameters such as biological data, OAC indication and concomitant therapy surrounding PCI. All clinical outcomes were also collected during hospitalization, at 2 and 12 months after PCI.Results: We prospectively analysed 359 patients (83% males; age 71+/- 10). 2$&LQGLFDWLRQVZHUH$WULDOEULOODWLRQYDOYXODUGLVHDVHVpulmonary embolism and deep venous thrombosis (12.3%) miscellaneous (12.3%). In 234 (65.2%) patients (group 1), OAC was discontinued while dual antiplatelet therapy was mandatory. The mean discontinuation time was 22+/- 31days. In 125 (34.8%) both dual antiplatelet therapy and OACwere continued.

Objective: We compared passive thrombus-aspiration catheters versus active mechanical thrombectomy devices in patients who underwent primary or rescue percutaneous coronary angioplasty (PTCA) in a tertiary hospital.Background: Many thrombectomy devices in the setting of patients with ST-segment elevation acute myocardial infarction (STEMI) are proved to be safe and effective in thrombus burden reduction and in ST-segment resolution (STR); yet there are no comparative data between devices.Methods: We analysed 232 consecutive patients underwent to primary or rescue PTCA from 2000 to 2007 in single tertiary hospital.
