Primary Outcome Measures
NameTimeMethod
Serum level of Lp-PLA2up to Day 60 after discharge
Secondary Outcome Measures
NameTimeMethod
Incidence of new-onset major vascular eventsup to 60 days after discharge

Major adverse vascular events include ischemic stroke, hemorrhagic stroke, TIA, myocardial infarction and vascular-related death.

carotid arterial intima-media wall thicknessDay0 and Day 60 after discharge
Canadian Cardiovascular Society (CCS) grading of angina pectorisDay 0 and Day 60 after discharge
Changes in the Serum Lipid, the high-sensitivity C-Reactive Protein(hs-CRP) and the Platelet Aggregation RateDay 0 and Day 60 after discharge
The proportion of patients in each treatment group who had clinically significant change as defined by the angina-frequency score on the Seattle Angina QuestionnaireDay 0 and Day 60 after discharge
Change in the electrocardiogram (EKG)Day 0 and Day 60 after discharge
Incidence of severe hemorrhagesup to 60 days after discharge

The definition of "Severe hemorrhages" is in accordance with the GUSTO bleeding criteria, including fatal intracranial hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH) or which could result in substantial hemodynamic compromise requiring treatment.

Incidence of moderate hemorrhagesup to 60 days after discharge

The definition of "moderate hemorrhages" is in accordance with the GUSTO bleeding criteria, which requires blood transfusion but not results in hemodynamic compromise.
