[Effect of twelve-month combined therapy with perindopril and indapamide on the level of blood pressure and left ventricular hypertrophy in patients with hypertensive disease].
Left ventricular hypertrophy (LVH) in patients with hypertensive disease is associated with unfavorable prognosis. Long term and effective antihypertensive therapy is capable to cause reverse development of LVH. We included in this study 72 patients (27 men, 45 women, age from 34 to 72 years) with untreated 1st and 2nd degree arterial hypertension (systolic blood pressure 140-179 mm Hg and/or diastolic blood pressure 99-109 mm Hg) and echocardiographical signs of LVH (left ventricular myocardial mass index >120 g/m2 in men and >100 g/m2 in women). After that the patients were randomized into 2 groups: the study group (39 patients, mean age 53.0+/-11.6 years) received combination of perindopril and indapamide in initial dose of 2 mg/0.625 mg, and comparison group (33 patients, mean age 54.4+/-8.2 years) received monotherapy with enalapril (10 mg). Once daily dosing of the preparation provided high level of compliance of patients with treatment. During 12-month therapy with combination of perindopril and indapamide target blood pressure (<140/90) was achieved in 74.4% of patients, during monotherapy with enalapril--in 27.3% of patients. Significant decrease of left ventricular myocardial mass index (LVMMI) with combination therapy was observed by 6th month of treatment (from 260 to 234 g), with monotherapy within same period of time--from 267 to 260 g. As a result of 12 months therapy of patients with I-II degree of hypertension with perindopril and indapamide LVMMI decreased by 17.5% while monotherapy with enalapril was associated with 5.6% decrease of LVMMI. Lowering of LVMMI occurred mainly at the account of decrease of left ventricular wall thickness.
