Immediate Surgical Complications Following Emergency Coronary Bypass Surgery in Acute Myocardial Infarction Patients
Jeya Suriya Lenin [2] | Priyanka Kasturia
Abstract: Despite the advancements in interventional cardiology, the role of coronary artery bypass grafting in acute myocardial infarction remains limited according to current recommendations. However, recent improvements in perioperative management, particularly in myocardial protection, have enhanced the outcomes of emergency surgical revascularization, especially in patients experiencing cardiogenic shock. Thus, there is a growing interest in evaluating the efficacy of emergency CABG in cases where interventional cardiology proves ineffective or in patients previously deemed incurable. This study aims to prospectively analyze the immediate clinical outcomes following early postoperative CABG to identify factors associated with early mortality. The study, based on a cohort of 129 hospitalized patients, predominantly diagnosed with ST - elevated myocardial infarction, examines various parameters including inotropic support duration, the necessity of intra - aortic balloon pump, incidences of kidney injury, respiratory failure, atrioventricular blockade, supraventricular tachyarrhythmia, and encephalopathy in the early postoperative period, alongside early mortality endpoints. Findings indicate a higher risk of acute left ventricular failure, IABP procedures, and inotropic support in patients with STEMI compared to non - STEMI cases. Moreover, STEMI patients are more prone to acute kidney injury and transient atrioventricular block post - CABG. While respiratory complications are predominantly associated with prolonged mechanical ventilation, NSTEMI patients exhibit a higher likelihood of supraventricular arrhythmia and encephalopathy. Notably, early mortality rates are significantly higher in the STEMI group, primarily attributed to acute heart failure, cardiogenic shock, and acute mitral regurgitation. These findings underscore the importance of considering AMI type in evaluating the risks and outcomes of emergency CABG, necessitating further long - term prospective studies to assess both short - term and long - term mortality risks and outcomes.
