Coronary heart disease (CHD) is a leading cause of high mortality, disability and reduced quality of life for patients. At the heart of coronary heart disease - ischemia and activation of oxidative stress. With concomitant hypertension, the condition of patients and the prognosis for the course of their disease deteriorates significantly. The prognosis of coronary heart disease, the occurrence of new hospitalizations or deaths from cardiovascular disease can be further assessed by monitoring ST2 and malonic dialdehyde (MDA). Traditional treatment of coronary heart disease does not always guarantee the achievement of the desired clinical results. That is why it is advisable to use in the complex treatment of patients with coronary heart disease and concomitant hypertension cytoprotectors and drugs that have antioxidant properties, such as meldonium and folic acid.

The aim of the research. Detect anti-ischemic activity in meldonium and folic acid and evaluate the effect of these drugs on the level of ST2, MDA in the blood in patients with coronary heart disease and concomitant hypertension.

Materials and methods. The research included 80 patients (women - 4, men - 76, aged 57,7 ± 9,8 years) with diagnoses of coronary heart disease: stable angina, functional class II-III (FC), chronic heart failure (CHF) I-IIa, FC II-III ", with concomitant arterial hypertension II-III stages, 2-3 degrees, risk 4 (very high), CHF I-IIa, FC II-III". Patients were divided into 4 groups of 20 patients, respectively: 1) patients who, in addition to basic therapy, were prescribed folic acid at a dose of 0.8 mg / d for six months; 2) patients who, in addition to basic treatment, were prescribed meldonium at a dose of 750.0 mg / d for six months; 3) patients who, in addition to basic treatment, were prescribed folic acid at a dose of  0.8 mg / d and meldonium at a dose of 750.0 mg / d for six months; 4) patients who were prescribed only basic antianginal, disaggregating, hypolipidemic treatment.The number of anginal attacks and doses of nitroglycerin during the day were determined, the results of the test with a 6-minute walk and the plasma concentration of ST2 and MDA before and after 6 months of treatment with meldonium and folic acid were evaluated.

Results. Found anti-ischemic activity in meldonium and its combination with folic acid. The combination of these drugs as an adjunct to basic therapy significantly reduced the concentration of ST2. Both drugs alone or in combination reduced the concentration of MDA in the blood of patients.

Conclusions. Our research showed the presence of anti-ischemic activity in meldonium, both when added to the basic therapy of patients with coronary heart disease and concomitant hypertension, and when used together with folic acid. In the groups of patients where these drugs and their combinations were used, the frequency of anginal attacks and the number of doses of nitroglycerin used during the day were significantly reduced.

The combined use of folic acid and meldonium when added to the basic therapy after 6 months significantly reduced the concentration of ST2 in the blood. Folic acid and meldonium showed pronounced antioxidant properties. At separate adding of these medications to basic therapy or their combined adding significantly decreased the concentration of MDA - a marker of oxidative stress.

Therefore, we consider it appropriate to use folic acid and meldonium in the complex treatment of patients with coronary heart disease with stable angina and concomitant hypertension.
