Combination blood pressure lowering in the presence or absence of background statin and aspirin therapy: a combined analysis of PROGRESS and ADVANCE Trials

Abstract

OBJECTIVES: To assess the effects of combination BP lowering on cardiovascular events and mortality in the presence of aspirin and/or statin therapy in a combined analysis of the ADVANCE and PROGRESS trials. METHODS: We conducted an analysis of 14 682 participants allocated combination therapy with perindopril and indapamide or placebo followed up for a mean of 4.2 years. Participants were stratified into four groups defined by background use of medications at baseline: statin, aspirin, both or neither. Linear mixed effect models were used to assess differences in BP and Cox proportional hazard models were used to estimate the risks of major cardiovascular events, all-cause mortality and tre..
