Evaluation of 100 cases of mortality after cardiac surgery -- a single-center experience in Bangladesh

Objectives : Vigilance is safety in cardiac surgery. Performance in cardiac surgery is frequently measured by short-term mortality. Several risk factors like advanced age, female gender, elevated body mass index, decreased left ventricular function, emergent and redo operations have appeared recurrently as poor prognostic variables. Evaluation of postoperative mortality is crucial to find loopholes to provide proper care and reduce preventable mortality after cardiac surgery in developing countries with limited infrastructures and resources. Methods: This is a retrospective study conducted in the Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University from 1 January 2014 to 30 May 2018. Statistical analysis of the data of 100 cases of mortality after cardiac surgery was done by collecting the demographics and clinical characteristics of the patients along with their perioperative data. Results: During the study period, about 1627 cases of cardiac surgery were done with an overall mortality rate of 6.15%. But the overall mortality rate is improving as in 2020 the mortality was under 5%. Conclusion: Mortality after cardiac surgery is multifactorial. A large-scale prospective study with comparative groups is required to find out preventable measures of mortality after cardiac surgery which will improve the quality of service provided to the patients in developing countries.
