Aim: to study effectiveness of a fixed combination of perindopril arginine and amlodipine besylate for the treatment of arterial hypertension with concomitant chronic cardiac insufficiency and signs of chronic kidney disease Materials and methods: 53 (44.9%) patients aged 64.5±8.2 yr with signs of chronic kidney disease (CKD) were selected from 118 subjects with grade II-III essential AH and chronic cardiac insufficiency They had an increased blood cystatin C level (mean 1.4±0.3 mg/l) and/or decreased glomerular filtration rate (GFR) calculated by 3 formulas: 77.6±15.9 (MDRD), 79.3±17.1 (CKD-EPI) and 57.7±15.2 ml/min/1. 73 m3 (from cystatin C level). Fixed combinations of perindopril arginine and amlodipine besylate (5/5, 5/10, 10/10 mg) were used to treat the patients. Their effectiveness was evaluated 2 months after the onset of therapy based on results of AP measurement, 24 hr AP monitoring, assessment of clinical conditions and 6 min walk test. Blood creatinine, urea and cystatin C levels and GFR were measured.
Results: Target AP was achieved in 82.6% of the patients. Systolic AP (SAP) decreased significantly from 172±11.2 to 135.7±8.2 mmHg (p<0.01), diastolic AP (DAP)from 110±6.9 to 85.3±7.2 mm Hg (p<0.5). Mean daily SAP and DAP decreased by 14.7 and 14.4% respectively. SAP and DAP load also decreased Clinical conditions estimated in terms of the CCI functional class improved (a decrease from 6.2±1.1 to 4.2±1.3 scores (p<0.01)). Tolerance of physical activity increased from 157.2±12.6 to 320.4±32.2 m (p<0.05). Blood cystatin C level decreased and GFR increased.
Conclusion: The fixed combination of perindopril arginine and amlodipine besylate ensures high therapeutic effect in patients with arterial hypertension and concomitant chronic cardiac insufficiency having signs of chronic kidney disease.
