Abstract/OtherAbstract:
INTRODUCTION: The aim of our study was to evaluate the safety and effectiveness of the free combination of amlodipine/valsartan in patients with arterial hypertension in a real-life setting. METHODS: This was a multicenter, open-label, observational, noninterventional, postmarketing surveillance study conducted in 298 centers in China, Malaysia, Pakistan, Bangladesh, Egypt, and Russia. We evaluated changes in heart rate, systolic and diastolic office blood pressure (BP), as well as BP control rate (<140/90 mmHg) overall, and in clinically relevant subgroups of hypertensive patients (BP >140/90 mmHg) after 12 weeks of treatment with 5/10 mg amlodipine and 80/160 mg valsartan combination. RESULTS: Two thousand seven hundred and eighty-five patients with arterial hypertension were enrolled, 52 discontinued (eight due to adverse events), and four patients' data were missing. In total, 2729 patients completed the study: mean age 57.9 years, 54.5% men, 54.2% Asian, 44.6% Caucasian; 86.5% had prior hypertension treatment (which was discontinued), baseline BP was 163.1/96.2 mmHg. The significant reduction in BP (-33.2/-16.9 mmHg, P<0.0001) was achieved with amlodipine/valsartan treatment resulting in a final BP of 129.9/79.3 mmHg. A dose-dependent effect was observed with the least BP reduction for 5/80 mg (-29.2/-15.1 mmHg, P<0.0001) and the greatest for the 10/160 mg dose regimen (-43.6/-22.4 mmHg, P<0.0001). Treatment response increased with increasing initial severity of hypertension with the least BP reduction in patients with baseline grade 1 hypertension BP level (SBP 140-159 mmHg): -20.0/-13.4 mmHg, P<0.0001, and the greatest BP drops observed in grade 3 hypertensive patients with baseline systolic BP over 200 mmHg: -73.1/-26.3 mmHg, P<0.0001. Patients with isolated systolic hypertension had BP reductions of -24.2/-4.8 mmHg, P<0.0001. CONCLUSION: An optimal BP reduction was achieved for all hypertension grades as well as isolated systolic hypertension, providing evidence that most hypertensive patients may benefit from amlodipine/valsartan combination treatment.
