This post hoc analysis of CAMELOT and PREVENT analyzed the impact of blood pressure variability (BPV, assessed as within-subject standard deviation of SBP from 12 weeks onward) on the incidence of major adverse cardiovascular events (MACE, defined according to original studies). Patients (n = 1677 CAMELOT; n = 776 PREVENT) were stratified by BPV quartile. Regardless of study, BPV was significantly lower for amlodipine versus other treatments. In CAMELOT, a significant association between BPV quartile and MACE was observed with amlodipine treatment. Significant associations between BPV quartile and MACE were observed for both studies, when analyzed overall (adjusting for treatment). In CAMELOT, with amlodipine treatment, an increased risk for MACE was observed with high (BPV ≥ Q3) versus low BPV (< Q1; adjusting for characteristics and risk factors). In both studies, increased risk for MACE was observed for BPV ≥ Q3 versus BPV < Q1 (analyzed overall, adjusting for treatment and covariates). For both studies, BPV, but not mean SBP, was associated with cardiovascular events. BPV was associated with cardiovascular outcomes in patients with CAD and well-controlled BP.
