Impact of Pre-, Intra-and Post-Operative Parameters on In-Hospital Mortality in Patients Undergoing Emergency Coronary Artery Bypass Grafting: A Scarce Single-Center Experience in Resource-Scare Setting

Background: At a time when cost containment in health care is under increased scrutiny, coronary artery bypass grafting remains the most widely performed cardiac surgical procedure in the world. This study compares 30-day mortality, morbidity, and resource use for off-pump coronary artery bypass (OPCAB) versus conventional coronary artery bypass (CCAB) revascularization.Methods: From January 2000 through December 2008, 1003 patients underwent OPCAB grafting by a single surgeon (S.C.S.). Data were prospectively collected, entered into a Society of Thoracic Surgeons adult cardiac surgery database, and analyzed retrospectively. We used propensity-matching techniques to match this cohort to a group of 1003 patients who underwent CCAB.Results: The hospital mortality rate was lower for the OPCAB patients than for the CCAB patients: 2.0% (20/1003) versus 2.8% (28/1003). Predictors of hospital mortality for the entire cohort included age (P = .001), cardiogenic shock (P = .001), congestive heart failure (P = .019), history of myocardial infarction (P = .001), and reoperation (P = .007). The overall incidence of morbidity was lower for the OPCAB patients (reoperation for bleeding, P = .011; prolonged ventilation, P = .035; stroke, P = .045; cardiac arrest, P = .004). OPCAB patients experienced significantly reduced procedure times (P = .001), postoperative ventilation times (P = .035), post-operative lengths of stay (P = .035), and blood product use (intraoperative, P = .001; postoperative, P = .001).Conclusion: These outcomes clearly demonstrate that OPCAB is a safe and effective procedure for myocardial revascularization. This retrospective, nonrandomized observational study has shown that the patients who underwent OPCAB had reduced morbidity and mortality, as well as decreased resource use, compared with those who underwent CCAB.

Introduction: There is paucity of data on the outcomes of coronary artery bypass grafting (CABG) among patients presenting with ST-segment elevation myocardial infarction (STEMI). Methods: We queried the National Inpatient Sample database (2002-2016) for patients with STEMI who underwent CABG. We reported the trends in utilization of CABG for STEMI, and the associated in-hospital outcomes. Using multivariable analysis, we compared in-hospital outcomes in patients undergoing CABG on hospitalization day 1 vs. day 2 vs. day ≥3 , in the early (2002 to 2009) and contemporary cohorts (2012 to 2016). Results: Our analysis yielded 2,910,960 patients with STEMI, of whom 7.6% underwent CABG (9.6% in 2002 versus 3.9% in 2016, P trend <0.001). There was an increase in in-hospital mortality (5.8% in 2002 versus 7.6% in 2016, P trend <0.001) which corresponded to an increase in comorbidities burden among patients undergoing CABG. There was a rising trend in performing CABG on hospitalization day ≥ 3 corresponding to an increase in the utilization of MCS and pre-CABG PCI during the study years. CABG was more likely to be performed on admission day 1 in patients with anterior STEMI, cardiogenic shock or mechanical complications. In the early cohort, CABG on day 1 and day 2 was associated with higher in-hospital mortality, while in the contemporary cohort only CABG on day 1 was associated with higher in-hospital mortality compared with CABG on day ≥ 3. CABG on day 1 was associated with higher rate of cardiac arrest, hemorrhagic stroke, blood transfusion and cardiac tamponade in the earlier cohort, while in the more contemporary cohort it was associated with higher blood transfusion. Conclusions: There was a downtrend in performing CABG for STEMI, and an uptrend in in-hospital mortality after CABG. Patients undergoing emergent CABG on day 1 were more likely to have mechanical complications and cardiogenic shock and were associated with higher in-hospital mortality.

Objectives: Minimally invasive extracorporeal circulation circuits provide several advantages compared to conventional extracorporeal circulation circuits. We compared the results of a minimally invasive extracorporeal circulation system with those of conventional extracorporeal circulation system, in patients undergoing isolated coronary artery bypass grafting. Methods: We identified 753 consecutive patients who underwent coronary artery bypass grafting at our centre between October 2014 and September 2016. These patients were divided into two groups: a minimally invasive extracorporeal circulation group (M, n = 229) and a conventional extracorporeal circulation group (C, n = 524). Baseline parameters, details of cardiac surgery as well as postoperative complications and outcomes were compared by means of a propensity-matched analysis of 180 matched pairs. Results: The median EuroSCORE II was 1.3%. Transfusion requirement of packed red blood cells (p = 0.002) was lower in Group M compared to conventional extracorporeal circulation systems. There were no differences in hospital mortality or in rates of adverse events between the matched groups. Total in-hospital mortality of the cohort was 1.7%. Conclusion: The use of minimally invasive extracorporeal circulation is associated with a significantly lower use of blood products after isolated coronary revascularisation. There were no differences concerning duration of surgery, complication rates and mortality between the groups. Therefore, the application of minimally invasive extracorporeal circulation systems should be considered as preferred technique in isolated coronary artery bypass grafting procedures.
