[Comparison of the long-term results of endovascular treatment and coronary artery bypass grafting for 5-year follow up].

UNLABELLED: The aim of the work was to compare the long-term results of angioplasty and coronary artery bypass grafting for 5-year follow up, to evaluate the effect of dyslipidemia, diabetes and systemic inflammation on the recurrence of angina during 5 years following operation. MATERIAL AND METHODS: Between 1939 and 2005 an analysis was made of the long-term results obtained in 793 patients after coronary artery bypass grafting and in 272 patients after angioplasty followed up for 5 years. The statistical calculations were performed using Analysis ToolPak - VBA entering superstructures of the electron table Microsoft Excel 2000. RESULTS: AS compared to the hospital period, there was a significant rise of the number of patients with the recurrence of angina, which was recorded five years after surgical treatment. The incidence of the recurrence of angina in the long-term period after operation was influenced by an increase in the content of total cholesterol, low density lipoproteins, alpha lipoprotein, C-reactive protein as well as by the presence of diabetes mellitus. CONCLUSION: It has been demonstrated that as compared to the conservative treatment, the quality of life was better after surgery; the number of patients in functional class 3-4 angina and the lethality were minimized. During five years of the follow up, repeated endovascular intervention turned out not inferior to coronary artery bypass grafting. However, it is necessary to foresee the possibility of performing 2,6 repeated procedures of angioplasty.
