Correction of the metabolic link of the natural course of ischemic heart disease (IHD) was found out to be a real reserve of enhancement of therapy efficiency in treating this condition. A total of 137 IHD patients were examined, presenting with functional class II-III exertional angina, their age ranging between 67 to 86 years. Kinds of metabolic complexes to be used in IHD treatment included amino acids, antioxidants, cofactors, energy-providing compounds that enhance efficiency of basic methods of IHD therapy. A positive therapeutic effect of metabolic correction treatments was evidenced by earlier dispelling of electrocardiographic signs of myocardial ischemia, higher tolerance to physical load, improvement in parameters characterizing cardio-hemodynamics.
