HEART FAILURE, PERIOPERATIVE COMPLICATION, ANEMIA
Heart failure (HF) is a common perioperative complication in older people with hip fracture, and it is also the second leading cause of in-hospital death, with an incidence ranging from 5.5 to 21.3% [At present, many scholars pay more attention to AHF, which has lead to a significantly improved understanding of its etiology. Cardiac history, age, anemia, and ASA score have been shown to be risk factors for AHF [Given the high incidence of AHF in older patients with hip fractures, it has become increasingly necessary to establish a prediction model for AHF. Therefore, we designed this study to explore the risk factors for perioperative AHF in old patients with hip fracture and to build a nomogram model.
