New Pharmacological Approach to Improvement of Quality of Life of Patients after Coronary Artery Bypass Grafting through Stimulation of Neoangiogenesis

INTRODUCTION: Despite the increased volume of rendered high-tech assistance and objective improvement of the condition of the majority of operated patients, the parameters of physical activity and working capacity in this category of patients remain low. AIM: To study the effect of 5-oxymethyluracil with angiogenic properties on the quality of life of patients in the early and long-term period after coronary artery bypass grafting (CABG). MATERIALS AND METHODS: The randomized prospective study included two groups of patients: the main group (n = 87) which in the perioperative period of CABG (5 days before and 14 days after surgery), in addition to standard therapy, received the drug 5-oxymethyluracil), and the control group (n = 81) which received standard therapy. The groups were comparable in gender, age, basic clinical and functional characteristics and peculiarities of surgical intervention. The quality of life of patients was determined by the Seattle Angina Questionnaire (SAQ) before CABG surgery (upon admission to the vascular surgery department) and after surgery (after 2 months and 1618 years). There were no statistically significant differences in the preoperative parameters of quality of life in the control and main groups. RESULTS: In the long-term period of surgical revascularization of the myocardium (1618 years after the operation) the severity of angina according to SAQ was: in the control group 33.30 (20.00-60.00), in the main group 60.00 (33.30-70.00; р = 0.0407). Other scales of SAQ, including physical activity, stability of anginal course, satisfaction with treatment and perception of the disease, did not demonstrate any differences between the studied groups in 2 months or 1618 years after CABG. CONCLUSION: Perioperative use of 5-oxymethyluracil influenced the improvement of only one parameter of quality of life according to the SAQ questionnaire the severity of angina, with statistically significant differences between the groups in the long-term period of CABG (1618 years after surgery). According to SAQ questionnaire, there was no effect on the remaining parameters of the quality of life with the underlying perioperative use of the studied drug in all follow-up periods.
