The risk factors of heart failure in elderly patients with hip fracture: what should we care

Background: Heart failure is a common adverse postoperative complication in elderly patients. It is necessary to explore the risk factors of heart after the operation of elderly patients with hip fracture during hospitalization. Methods: Patients with hip fractures admitted to our hospital from January 1, 2019 to December 31 2020 were included, all the patients received internal fixation surgery. The characteristics of patients with and without postoperative heart failure were compared. Multivariate logistic regression analyses were applied to analyze the risk factors of heart failure in elderly patients with hip fracture. Results: A total of 283 patients with hip fractures were included, the incidence of heart failure was 12.37 %. There were significant differences in the age, hypertension, anemia hypoalbuminemia and duration of surgery between heart failure and no heart failure group(all p < 0.05). There were no significant differences in the gender, BMI, diabetes mellitus, hyperlipidemia, history of heart failure, cognitive dysfunction, type of fracture, preoperative oxygen saturation, white blood cell count, platelet count, red blood cell count, creatinine, alanine aminotransferase, aspartate aminotransferase and estimated blood loss during surgery between heart failure and no heart failure group(all p > 0.05). Logistic regression analyses indicated that age >= 70y (OR2.446, 95% CI1.044 similar to 4.149), hypertension(OR2.152, 95% CI1.125 similar to 4.023), anemia(OR3.094, 95% CI1.294 similar to 5.907), hypoalbuminemia(OR2.377, 95% CI1.205 similar to 4.537), duration of surgery >= 120 min(OR1.683, 95% CI1.094 similar to 2.782) were the risk factors of heart failure in elderly patients with hip fracture(all p < 0.05). Conclusions: The incidence of postoperative heart failure in elderly patients with hip fracture is relatively high, which is the result of a combination of high-risk factors. Peri-period risk assessment and prevention of related risks are the keys to a good prognosis for patients.
