Abstract

Highlights: The 30-day, 60-day, 3-month, 6-month, and 1-year postoperative cumulative mortality rates were respectively 1.6%, 3.6%, 5.1%, 8.4%, and 12.9% in the non-HF group, and 5.7%, 9.5%, 12.4%, 17.1%, and 25.2% in the HF group ( p ≤ 0.001). The factors that affected 1-year mortality were sex (OR, 2.10; 95% CI, 1.62–2.72; p < 0.001) and age (OR, 1.04; 95% CI, 1.02–1.06; p < 0.001) and presence of HF (OR, 1.62; 95% CI, 1.45–1.86; p = 0.005). In subgroup analysis, the factors that affected 30-day mortality were only moderate-to-severe HF (OR, 4.01; 95% CI, 1.10–8.78; p = 0.009). In elderly patients with hip fracture, the comparison between the HF and non-HF patients revealed that HF was an independent factor of mortality at a minimum of 1-year follow-up. Severity of LV systolic dysfunction classified by LVEF in patients with hip fracture was also a risk factor of 30-day mortality. Abstract: Introduction: We designed a comparative study using elderly hip fracture patients with and without heart failure (HF). The purpose of this study was to assess 1) prevalence of HF, compare 2) early and late mortality after elderly hip fracture between HF and non-HF patients and to assess 3) risk factors of mortality after hip fractures in elderly patients with HF. In addition, we also investigated 4) whether there is a difference in mortality according to the severity of left ventricular (LV) systolic dysfunction classified by LV ejection fraction (EF) in HF patients through subgroup analysis. Methods: This study included 1992 patients (1992 hips) who were diagnosed as having unilateral femoral neck or intertrochanteric fractures and who underwent surgery at two hospitals between January 2004 and June 2018. The patients were categorized into a non-HF group (1782 patients) and a HF group (210 patients; mild [119 patients] and moderate-to- severe HF subgroups [91 patients]). The cumulative crude mortality rate was calculated, and 30-day, 60-day, 3-month, 6-month, and 1-year mortality rates were compared between the non-HF and HF. Logistic regression analysis was conducted to identify independent factors associated with mortality. Results: Of 1992 patients, 210 (10.5%) patients were diagnosed with HF. The 30-day, 60-day, 3-month, 6-month, and 1-year postoperative cumulative mortality rates were respectively 1.6%, 3.6%, 5.1%, 8.4%, and 12.9% in the non-HF group, and 5.7%, 9.5%, 12.4%, 17.1%, and 25.2% in the HF group ( p ≤ 0.001). The factors that affected 1-year mortality were sex (OR, 2.10; 95% CI, 1.62–2.72; p < 0.001) and age (OR, 1.04; 95% CI, 1.02–1.06; p < 0.001) and presence of HF (OR, 1.62; 95% CI, 1.45–1.86; p = 0.005). In subgroup analysis, the factors that affected 30-day mortality were only moderate-to-severe HF (OR, 4.01; 95% CI, 1.10–8.78; p = 0.009). Conclusions: In elderly patients with hip fracture, the comparison between the HF and non-HF patients revealed that HF was an independent factor of mortality at a minimum of 1-year follow-up, and severity of LV systolic dysfunction classified by LVEF in patients with hip fracture was also a risk factor of 30-day mortality.
