The Influence of Preoperative Hematocrit Levels on Early Outcomes in Patients undergoing Cardiac Surgery

Background: Anemia is a common risk factor for cardiovascular disease. The impact of preoperative anaemia is unclear in cardiac surgery. Preoperative anaemia affects early findings in patients undergoing cardiac surgery. Aim and Objective: The main objective of current research was to investigate the impact of preoperative anaemia on early outcomes in heart surgery patients. Material and Methods: A prospective randomized clinical research was undertaken after obtaining written informed consent from patients for cardiac surgery at the PIC, Lahore between Apr 2020 and Feb 2021. A total of 120 individuals between the ages of 20 and 60 were chosen for the research. Preoperative anaemia was described as Hb levels of <13 g/dl for males and <12 g/dl in female patients undergoing cardiac surgery. Results: Total 120 patients were enrolled and stratified into two groups (60 patients each) with average age 5 +/- 5.75 years. Early outcomes after surgery such as postoperative stroke (6.67 % versus 1.6 %), AF (37 % versus32 %), and duration of hospital stay > 7 days (50 % vs 41.67 %) were found to be different between anaemic and normal Hb groups. Conclusion: Preoperative anaemia can be increased risk of morbidity and mortality in patients after surgery. Low preoperative Hb found as advanced risk factor for death, renal impairment, stroke, AF and long hospital stay in our research.
