Clinical Effectiveness of Cardiocytoprotective Therapy in Patients with Acute Coronar Syndrome (ACS) – Myocardial Infarction (MI), Who Were Performed Balloon Angioplasty and Coronary Artery Stenting

The aim of the study was to increase the efficiency of restorative treatment of patients with Acute Coronary Syndrome (Miocardial Infarction) by incorporating the protocol therapy for the course of parenteral use of L-arginine and L-carnitine (Tivorel). It has been determined that patients with ACS (MI) after percutaneous coronary intervention often develop reperfusion syndrome with manifestations of left ventricular insufficiency and rhythm disturbances. Substantial clinical and functional improvement was noted under the influence of standard medical treatment in patients of control group. At the same time postinfarction remodeling with systolic and diastolic function of the heart, with the development of heart failure syndrome and endothelial dysfunction of blood vessels, and also remained resistant to extrasystole therapy, progressed. Patients in the experimental group under the influence of complex medical treatment with the inclusion of L-arginine and L-carnitine marked a significant decrease in the frequency of violations of rhythm and conduction for the second day of observation, as well as a decrease in the manifestations of post-infarction remodeling of LV, which ultimately manifested a significant improvement in myocardial contractility (EF increased by 13%) and decreased diastolic dysfunction. Improvement of the inotropic function of the heart and a significant reduction in the frequency and severity of reperfusion arrhythmias was achieved precisely due to cardiometabolic effects of L-carnitine. In addition, in patients undergoing additional treatment with L-arginine and L-carnitine after 10 days of treatment, the activity of ET-1 was significantly lowered and the concentration of nitrogen oxide metabolites in the blood plasma increased and reach the level of healthy subjects (p>0.05). So, they recovered the endothelial function of the vessels.
