Introduction: The risk of sudden cardiac death (SCD) in patients with diabetes after coronary artery bypass graft surgery (CABG) has not been studied in a contemporary clinical trials of surgical revascularization. This report analyses an incidence, timing and mechanistic predictors of sudden cardiac death after CABG in a diabetic patient.
Case Report: We report a case of an elderly diabetic patient with normal left ventricular ejection fraction and relatively low-risk profile for elective CABG surgery. In an uneventful postoperative routine, sudden cardiac death was unexpected on mild to moderate exertional activity.
Conclusion: The physiological events during defecation induced straining are simulated valsalva maneuver and may have led to syncope and cardiorespiratory arrest. Considering growing volume of diabetic patients with multivessel coronary artery disease, meticulous critical care monitoring guidelines are needed to be continuously optimized for successful postoperative intensive care.
