Personalized trimetazidine prescription as a cytoprotective agent in patients with coronary artery disease
Published 2021-07-01“…The criteria for predicting the trimetazidine cytoprotective effect were determined using Wald statistics.Results. When trimetazidine was injected into a WBC suspension sample, two types of cell viability changes were observed: in 60% of patients, CVI increased, on average, by 37% (from 23% to 60%, p<0,001) and in 40% of patients, CVI decreased, on average, by 30% (from 54% to 24%, p<0,05).A number of conditions of the patient initial status were identified for the manifestation of trimetazidine cytoprotective activity: grade 1 hypertension; right ventricular end diastolic dimension up to 30 mm according to echocardiography; normal lipid profile with a total cholesterol <5,3 mmol/L, very-low-density lipoproteins <1 mmol/L and an atherogenic coefficient up to 3 CU, myocyte and cardiomyocyte destruction (total CPK >100 U/L and CPK-MB >15 U/L), normal liver function (alanine aminotransferase <25 U/L), renal dysfunction (total protein <75 g/L, urea >8 mmol/L and blood creatinine >100 pmol/L), normal thrombopoiesis (immature platelet fraction <5%) and the state of functional adaptive system resistance (blood lymphocytes <30% and neutrophils >4x109/L).Conclusion. …”
