Randomized Controlled TrialEffectiveness of blood pressure-lowering treatment by the levels of baseline Framingham risk score: A post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT).
This was a post hoc analysis of Systolic Blood Pressure Intervention Trial (SPRINT), aimed to investigate whether intensive blood pressure treatment has differential therapeutic outcomes on patients with different baseline Framingham risk score (FRS). The 9298 SPRINT participants were categorized into low-risk (baseline FRS < 10%), intermediate-risk (FRS = 10%-20%), or high-risk (FRS > 20%) arms. The primary outcome was a composite of myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure, or death from cardiovascular causes. ⋯ And, for all-cause mortality, the hazard ratio with intensive SBP treatment was 1.58 (95% CI: 0.55-1.06), 0.9 (95% CI: 0.26-9.50), and 0.53 (95% CI: 0.34-0.82) in three arms (all P values for interaction > 0.05). Effects of intensive versus standard SBP control on serious adverse events were similar among patients with different FRS. Our results suggested that regardless of the FRS level, the intensive blood pressure control was beneficial.
