Evaluation of patients survival with coronary heart disease after coronary bypass surgery depending on the passage of recovery phase

Abstract

In a retrospective study based on the register of patients with coronary heart disease after coronary artery bypass grafting clinical and functional characteristics and long-term survival in 2398 men, age 54,8±6,3 were analized, depending on the passage of the recovery phase from 2000 to 2009. The results showed that people of pre-retirement age were sent to the sanatorium therapy stage (72,5%) with a mild coronary and myocardial insufficiency. Mortality in the long-term period of 1 year to 10 years in the group after sanatorium therapy stage was 7,9%, whereas among patients who have not undergone sanatorium rehabilitation mortality rate was higher – 8,4%. Analysis of survival by Kaplan-Meier method of patients after sanatorium rehabilitation revealed that 3, 5 and 10-year survival rate was significantly higher than in those that did not pass the sanatorium stage of treatment. Two tests – Gehan's Wilcoxon Test (p=0,01835), Cox-Mantel Test (p=0,02820) – confirmed the accuracy of the comparison groups.
