Влияние фиксированной комбинации амлодипина и периндоприла (препарат Престанс) на механизмы тепловой адаптации у больных артериальной гипертонией

Abstract

Relevance. The impact of the drugs on adaptation to the heat wave of abnormal temperature has been one of the most important practical medicine questions, concerning heat waves, recent years. One of the points at issue is safety administration of calcium channel antagonists and ACE inhibitors during abnormal heat.Aim of the study is to assess the efficacy and safety of the fixed combination of perindopril arginine (drug Prestance, Servier Industries, Ltd.)/amlodipine in patients with arterial hypertension (AH) during the summer heat and the summer heat influence on the mechanisms of heat adaptation to abnormally high temperature.Material and methods: The study enrolled 165 patients with stages 1-2 AH: 69 patients with average risk and 91 patients with high/very high risk of cardiovascular complications. There were 69 men and 96 women in the study, living in Moscow city, in the Moscow and in the Ivanovo Regions. All patients were measuring office BP, undergoing biochemical analysis of blood, running questionnaire survey: visual analogue scale (VAS), questionnaire for the patients who were exposed to heat, the level of products reacting with the 2-thiobarbituric acid (malonyldialdehyde, MDA) and activity of superoxide dismutase (SOD) using standard test-kits and the pulse ware velocity (PWV) was measured in 30 patients. The first visit was in the first half of June 2013, the second visit - during the heat (July 2013) and the third one in September 2013.Results: In the course of the study SBP (systolic BP) and DBP (diastolic BP) were reduced (р<0,00001), target level of SBP and DBP reached 73,9% (41,9% - the second visit).We observed the increase of VAS scores, hyperkalemia (р=0,0056), hyponatremia (р=0,00042), hypocreatinemia (р=0,018), hypocholesterolemia (р<0,00001), hypotrigliceridemia (р=0,027), hypoglucosemia (р=0,0035). We were observing the reduction of PWV and of the characteristics of oxidative stress (MDA, р<0,0001 and MDA/ SOD, р<0.001) during the peak of the heat, during the 3ed visit. Conclusion: Prestance therapy during the summer heat showed efficacy and safety and was well tolerated by AH patients without any signs of hypotension and electrolyte imbalance which were attributed to body heat. The improvement of adaptive human body response was associated with effective arterial elastance and reduction of oxidative stress.
