A survival after coronary artery bypass grafting surgery with ejection fraction below ۳۰ percent

Introduction: Regarding the progress in surgeries, the mortality rate of coronary artery bypass grafting surgery is still low, despite advanced age and comorbidities. One of the independent causes of mortality rate is low ejection fraction (EF). This study aimed to assess mortality after coronary artery bypass grafting (CABG) operation in patients with ejection fraction under ۳۰%. In the present study the experience of ۲۰ patients with an EFbelow ۳۰% and ۲۰ patients with an EF above ۳۰% was investigated in Birjand in which only three of the patients died within ۲ years after the operation. Methods: This crross-sectional descriptive study was conducted on ۴۰ patients in Birjand Vali-e-aser Hospital. Out of the ۴۰ cases, ۲۰ patients had EF below ۳۰% and ۲۰ subjects had EF above ۳۰ %. The files of all the cases undergoing heart surgery with an EF were obtained since ۲۰۱۵ to ۲۰۱۷, and then their demographic features, such as addresses and phone numbers were collected. Afterwards, they were called and their mortality was checked and the data were analyzed with independent-samples t-test. In addition, the ratios were examined in SPSS Software (version ۲۲) and P-value considered higher than ۰.۰۵. Results: From ۲۰۱۵ to ۲۰۱۷, the two groups, including ۲۰ patients with EF<۳۰% and ۲۰ patients with EF>۳۰%, undergone CABG surgery in Birjand University of Medical Science, ۶۵% of which were men and ۳۵ % were women with the age range of ۶۴.۷ for the cases with EF<۳۰ and ۶۲.۵ for the subjects EF>۳۰. One of the patients died with an EF above ۳۰% and two subjects died with EF below ۳۰%. Conclusions: The mortality rate can be reduced with providing appropriate care despite the fact that an EF<۳۰% is an independent cause of mortality and according to the results of the present study which showed three patients died after the CABG operation.
