Clinical efficacy of a fixed-dose combination of amlodipine/indapamide/perindopril in patients with hypertension and multiple risk factors

Abstract

Aim. To evaluate the antihypertensive and organ protective efficacy of the triple fixed-dose combination of amlodipine/indapamide/perindopril in patients with hypertension (HTN) who did not achieve target blood pressure (BP) on previous antihypertensive therapy (AHT).Material and methods. The study included 47 patients with HTN and multiple risk factors who did not achieve target blood pressure during previous AHT. They were prescribed triple fixed-dose combination of amlodipine/indapamide/perindopril with preliminary prescription of amlodipine, indapamide and perindopril in the free-dose combination. At baseline and after 3 months of AHT, 24-hour ambulatory blood pressure monitoring (ABPM), echocardiography and arterial stiffness were analyzed.Results. Initially, in patients included in the study, the main ABPM parameters were increased, while non dipper and reduced dipper (66% of patients) patterns prevailed. The results of echocardiography indicated left ventricular (LV) hypertrophy (LVH) by left ventricular mass index (LVMI), left ventricular posterior wall thickness (LVPWT), interventricular septum (IVS) and its diastolic dysfunction by E/A, while an increase in CAVI and biological vascular age reflected an increase in arterial stiffness. After 3 months of AHT, significant (p£0,05) ABPM changes and a predominance of the dipper-type 24-hour BP pattern were recorded in more than half of the patients (53%). A decrease in LVMI, LVPWT and IVS by 7%, 12% and 8%, respectively (p£0,05), while an E/A increase by 12% reflected LVH regression and LV diastolic function improvement. A decrease in arterial stiffness was evidenced by a decrease (p£0,05) in CAVI by an average of 10% and biological vascular age by 4 years.Conclusion. Triple fixed-dose therapy of amlodipine/indapamide/perindopril after 3-month treatment made it possible to achieve target blood pressure in 78% of patients, improved ABPM parameters and ensured pronounced cardioand vasoprotective effects, reflected in LVH regression, improvement of LV diastolic function and reduction of arterial stiffness.
