Risk Factors of Postoperative Acute Heart Failure in Elderly Patients After Hip Fracture Surgery.

Background Postoperative acute heart failure (AHF) in elderly patients after hip fracture surgery is a common complication. Therefore, this study aimed to identify the risk factor of AHF after hip fracture surgery among the older population. Methods This retrospective cohort study was performed on 88 admitted patients whose hip fractures were fixed via internal fixation surgery in a tertiary care hospital in Rawalpindi, Pakistan, from January 2022 to March 2023. Recruitment of patients was made through established inclusion and exclusion criteria. Ethical approval and informed consent were also gained before the data collection. A self-designed form was used to collect data. Data analysis was carried out in the IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States). Both descriptive and inferential statistics were applied to compare the attributes of the patients with AHF and patients without AHF. Multivariate logistic regression was used to evaluate the association between the postoperative AHF and its potential risk factors. Results Out of 88 enrolled patients, 12 (13.64%) had developed postoperative AHF. Age ≥ 65 years (OR = 2.606, 95% CI = 1.035~4.160, p = 0.010), anemia (OR = 3.178, 95% CI = 1.847~5.990, p = 0.029), hypertension (OR = 2.019, 95% CI = 1.110~4.034, p = 0.012), diabetes mellitus (OR = 2.003, 95% CI = 1.115~4.012, p = 0.015), hypoalbuminemia (OR = 2.486, 95% CI = 1.218~4.619, p = 0.030), and operation time ≥ 120 minutes (OR = 1.702, 95% CI = 1.099~2.880, p = 0.018), were the risk factors of postoperative AHF in elderly patients after hip fracture surgery. Conclusions In the study population, the incidence of postoperative heart failure was significant and age ≥ 65 years, anemia, hypertension, diabetes mellitus, hypoalbuminemia, and operation time ≥ 120 were significantly involved in the development of it. Preoperative identification and management of AHF risk factors could lead to the prevention of postoperative complications.
