CLINICAL ERGOSPIROMETRY IN PATIENTS WITH SURGICAL TREATMENT OF ISCHEMIC CARDIOMYOPATHY

Physical performance is one of the criteria for human health. Evaluation of physical performance has great diagnostic and prognostic significance. The most strict and quantitative parameter useful for standardization of the exercise tests is peak oxygen consumption measured by the ergometry method. Aim: The aim of the study was to evaluate informativeness and safety of the cardiopulmonary exercise test in patients with ischemic cardiomyopathy. The study comprised data of 260 patients with ischemic heart disease and severe left ventricular dysfunction. Patients were operated in accordance with the principle of “Triple V” (ventricle, vessel, valve) during the period from 2012 to 2014. Physical  erformance was evaluated preoperatively and one to two years after surgical treatment. Statistically significant increase in peak oxygen consumption (p<0.05) and, therefore, higher quality of life of patients was found in groups of isolated coronary artery bypass grafting (CABG), CABG and mitral repair, and CABG and surgical ventricular restoration (SVR) of the left ventricle med-term after surgery. In patients with CABG, mitral repair, and SVR, an exercise-induced increase in peak oxygen consumption was insignificant. Cardiorespiratory test is an informative and safe method of study for the evaluation of the results of surgical treatment in patients with ischemic cardiomyopathy. This method involves physical exercise with control of vital signs of the organism. Patients with ischemic cardiomyopathy require surgical treatment based on “triple V” principle. Significant improvement of physical performance was found in groups of isolated CABG, CABG and mitral repair, and CABG and SVR.
