Clinical efficiency of prehabilitation program in patients undergoing coronary artery bypass grafting

Aim.To evaluate clinical efficacy of high-intensity exercise training included in the prehabilitation program for elective coronary artery bypass grafting (CABG).Methods. 38 male patients were included in the study before on-pump CABG. After fulfilling the inclusion/exclusion criteria, patients were randomized into two groups: Group 1 patients (n = 20) underwent supervised treadmill exercise, and Group 2 patients (n = 18) were referred to surgery without any exercise training. Patients underwent a 7-day exercise training with daily measurements of hemodynamic parameters and electrocardiogram (ECG) monitoring. The load intensity was measured with cardiopulmonary exercise testing and accounted for 80% of the maximal oxygen uptake. Postoperative complications were recorded in the in-hospital period and analyzed. Quality of life indicators were measured by the SF-36 standard version 7–10 days prior to surgery and on days 7-10 of the postoperative period. Adherence to drug and non-drug therapy was assessed during the 6-month follow-up.Results.There was a significantly lower incidence of postoperative complications during the in-hospital period in patients undergoing prehabilitation program with supervised high-intensity exercise training, compared with patients without any exercise training (p = 0.002). Group 1 patients had reliably better mental health (MH) scores compared with Group 2 patients (48.9±7.60 vs. 39.1±6.80 scores, respectively; p = 0.03) on days 7–10 after CABG. Six months after the CABG, patients who underwent prehabilitation exercise training were less likely to resume smoking than patients without any exercise training (p = 0.04). The tendency towards improved adherence to drug therapy and compensation in arterial hypertension has been determined among Group 1 patients.Conclusion. Exercise training included in the prehabilitation program proved to be safe and effective in terms of improved clinical outcomes after CABG, quality of life and adherence to treatment in this group of patients.

Objective: To investigate the association of platelet to lymphocyte ratio to mortality and morbidity after coronary artery bypass grafting operation. Methods: We evaluated records of 916 patients who underwent coronary artery bypass grafting operation between January 2009 and May 2014 retrospectively. Patients were grouped as Group 1 (n = 604) if the platelet to lymphocyte ratio was above 142 and Group 2 (n = 312) if platelet to lymphocyte ratio was below 142. Results: The number of patients who developed a neurologic event during the hospital stay and in the first postoperative month was 7 (1.2%) in Group 1 and 12 (3.8%) in Group 2 for which the difference was statistically significant (P = .007). Early term mortality occurred in 3 patients (0.5%) in Group 1 and in 10 patients (3.2%) in Group 2 for which the difference was statistically highly significant (P = .001). In univariate and multivariate regression analysis, the preoperative platelet to lymphocyte ratio was determined as an independent risk factor for occurrence of atrial fibrillation in the early postoperative period, reoperation for sternum dehiscence, occurrence of a neurologic event, prolonged stay in the hospital and mortality. Conclusion: In this study, elevated levels of platelet to lymphocyte ratio were associated with mortality and morbidity after coronary artery bypass grafting operation.
