High blood pressure (BP) is a major risk factor associated with stroke in China. This is a subanalysis of patients from the China Status II study, aimed to evaluate the effectiveness and safety of valsartan/amlodipine (Val/Aml) single-pill combination (SPC) in hypertensive patients with different stroke subtypes (hemorrhagic, ischemic, or mixed).
China Status II was a multicenter, postmarketing, prospective observational study in hypertensive patients uncontrolled on monotherapy. The study was an 8-week open-label treatment period with 2 4-week follow-ups. Change in BP from baseline to weeks 4 and 8, BP control rate, and response rate at weeks 4 and 8, and safety of 8-week treatment with Val/Aml (80/5 mg) were assessed.
A total of 565 hypertensive patients with different types of stroke were analyzed in this China Status II substudy. Significant mean sitting systolic/diastolic BP (MSSBP/MSDBP) reductions from baseline to week 8 were observed across all stroke subtypes (P < .0001). At week 8, percentages of patients achieving MSSBP response (≥20 mm Hg reduction from baseline) were 76.3%, 74.4%, and 85.7%, MSDBP response (≥10 mm Hg reduction from baseline) were 67.8%, 65.9%, and 64.3%, and BP control (<140/90 mm Hg) were 74.6%, 80.5%, and 92.9%, in the hemorrhagic, ischemic, and mixed stroke subgroups, respectively. Adverse events (AEs) and serious AEs were reported in 5 patients (1%) and 1 patient (0.2%), respectively, in the ischemic stroke subgroup, while no AEs were reported in hemorrhagic and mixed stroke subgroups.
Val/Aml SPC was effective in hypertensive patients with different stroke subtypes and was well tolerated.
