Abstract Background The aim of this study was to explore the underlying impact of obstructive sleep apnea (OSA) on postoperative parameters of multi-organ function, including cardiac and cerebral vascular, respiratory as well as renal postoperative complications, among coronary heart disease (CHD) patients following elective coronary artery bypass grafting (CABG). Methods Electronic literature databases, including PubMed, ISI Web of Science, Directory of Open Access Journals, and the Cochrane Library electronic databases, were searched manually and automatically for relevant English articles. All of the selected articles focused on a comparison of the incidence of primary and secondary outcomes in CHD patients undergoing elective CABG with and without OSA. Results A total of 13 articles met our inclusion criteria. The current study demonstrated OSA significantly increased the incidence of major adverse cardiac and cerebrovascular events (MACCEs) in CHD patients undergoing elective CABG compared with the controls (odds risk (OR), 1.97; 95% confidence interval (CI), 1.50 to 2.59, p <0.0001). In addition, OSA was associated with an increased risk of new revascularization in CHD patients undergoing elective CABG (OR, 9.47; 95% CI, 2.69 to 33.33, p <0.0001). Moreover, reintubation and tracheostomy in the OSA group was increased (OR, 3.43; 95% CI, 1.35 to 8.71; p =0.009) and 372% (OR, 4.72; 95% CI, 1.23 to 18.13; p=0.024), respectively, compared with the control group. Besides, we also confirmed OSA significantly increased the acute kidney injury (AKI) incidence by 124% (OR, 2.24; 95% CI, 1.07 to 4.72; P < 0.0001). Finally, our results demonstrated that OSA increased medical resource utilization including length of postoperative hospital stay and ICU stay. Conclusions OSA may contribute to postoperative multi-organ dysfunction among CHD patients undergoing elective CABG by increasing the incidence of MACCEs, especially new revascularization, as well as respiratory, and renal complications. Peri- and postoperative management of CHD patients with OSA may be optimized to minimize the rate of postoperative parameters of multi-organ dysfunction, further reducing the consumption of limited medical resources.

The outcome of coronary artery bypass surgery depends on complete revascularization. In our paper, we attempt to demonstrate that Off-pump coronary artery bypass (OPCAB) is applicable to coronary heart disease patients with low LVEF. Low LVEF does not affect cardiac revascularization. Low LVEF is an independent risk factor for the outcome of CABG patients, but it does not mean that the OPCAB procedure leads to poor outcomes. In our hospital, we used on-pump CABG or conventional bypass surgery for coronary heart disease patients with low LVEF before 2010.With the accumulation of cases, OPCAB is now used in more than 95% of coronary artery bypass grafts in our center. Our data suggest that OPCAB is safe and reliable for patients with low LVEF.

Abstract. Introduction. Coronary heart disease, the complexity of the surgery conducted, inflammatory reaction to extracorporeal circulation and the need for perioperative anticoagulation influence perioperative state of hemodynamics during the surgical revascularization of a myocardium in patients with coronary heart disease. The aim. To improve the results of treatment of cardiac surgery patients with heart failure who underwent surgery, namely, coronary artery bypass grafting using extracorporeal circulation by improving methods of diagnosing heart failure. Materials and methods. 100 cardiac surgery patients with coronary heart disease were operated on at State Institution of Science “Research and Practical Center of Preventive and Clinical Medicine” State Administrative Department. In all the cases, coronary artery bypass grafting was performed using artificial circulation. In patients of group 1 (40 patients) in the postoperative period, the correction of hemodynamic disorders was performed according to the standard protocol. In group 2 (60 patients) - a differentiated approach to the correction of hemodynamic disorders was used. Results. It was found that in group 2 for stabilization of hemodynamics, oxygen status, microcirculation, smaller doses of sympathomimetics and shorter duration of their use, P <0.05 than in 1 were applied. Conclusions. The results of the studies indicate the possibility of using the method of phasography, in particular, the analysis of symmetry of the T wave, as a marker of ischemic changes in the myocardium in cardiac patients who underwent coronary artery bypass grafting using artificial circulation. The obtained data show that the developed algorithm of perioperative management of cardiac surgery patients with heart failure makes it possible to significantly accelerate the rehabilitation of cardiac surgery patients, increase patient comfort and reduce the length of their hospitalization. The possibility of using phasography for monitoring of myocardial condition in patients undergoing coronary artery bypass surgery has been investigated.

This study was designed to evaluate the clinical significance of simultaneous heart valve surgery and coronary artery bypass grafting for patients with valvular heart disease complicated by coronary heart disease and its influence on their prognosis. A total of 121 patients with valvular heart disease complicated by coronary heart disease who were surgically treated in our hospital from January 2013 to March 2017 were selected. The observation group (OG) (64 patients) underwent simultaneous valvular heart surgery and coronary artery bypass grafting. The control group (CG) (57 patients) underwent non-synchronous heart valve surgery and coronary artery bypass grafting. The operation, hospitalization, occurrence of adverse events and changes of cardiac function indexes of patients from the two groups were compared, and the factors affecting their prognosis were confirmed in multivariate analysis. The ventilator application time, postoperative ICU monitoring time, postoperative general ward time and total incidence of adverse events in the OG were lower than those in the CG (P<0.05). After treatment, the cardiothoracic ratio, left ventricular end-diastolic volume and BNP content in the two groups were markedly higher than before treatment, and the increase in the OG was more obvious (P<0.05); the left ventricular ejection fraction in both groups was markedly lower than that before treatment (P<0.05), and the decrease in the OG was more obvious (P<0.05). Multivariate analysis showed that hypertension, treatment methods, course of disease and age were independent risk factors affecting the prognosis of patients with valvular heart disease complicated by coronary heart disease. Simultaneous heart valve surgery and coronary artery bypass grafting can reduce the occurrence of adverse events and improve cardiac function indexes, which is worthy of clinical application. Hypertension, treatment methods, course of disease and age are independent risk factors affecting the prognosis of those patients.
