With the rising number of hip surgeries, simple and cost-effective tools for surgery risk assessment are warranted. The analysis of heart rate variability (HRV) may not only provide critical insights into the general frailty of patients with hip surgery, but also allow for better differentiation of health profiles in different hip surgery groups. Using HRV analysis, the present study compared cardiovascular as well as anthropometric parameters between patients with hip surgery, the hip fracture surgery group (HFS) and the total hip arthroplasty group (THA), and a control group.
71 participants (56.3% women), aged 60-85 years, took part, divided into three groups-patients after hip surgery (21 HFS and 30 THA patients) and a control group (20 participants). Electrocardiogram was recorded at baseline and after the application of a physical stressor (grip strength). A 3 (group) × 2 (time) repeated measures ANOVA, and a chi square test were carried out to test for group differences.
Higher weight (p = .002), body mass index (p = .001), and systolic blood pressure (p = .034) were found in THA patients compared to HFS patients. Lower calf circumference (p = .009) and diastolic blood pressure (p = .048) were observed for the HFS group compared to the control group. For cardiovascular parameters, significant differences emerged between the HFS group and the control group in HR (p = .005), SDNN (p = .034) and SD2 (p = .012). No significant differences in cardiovascular parameters were observed between the two hip surgery groups: neither at baseline nor during stressor recovery.
While HRV seems to differentiate well between HFS patients and controls, more research with larger samples is needed to scrutinize similaritites and differences in cardiovascular profiles between HFS and THA patients.
随着髋关节手术数量的增加，需要简单且具有成本效益的手术风险评估工具。心率变异性（HRV）分析不仅可以为髋关节手术患者的整体脆弱性提供重要见解，还可以更好地区分不同髋关节手术组的健康状况。本研究使用 HRV 分析比较了髋关节手术后患者、髋关节骨折手术组（HFS）和全髋关节置换术组（THA）以及对照组的心血管和人体测量参数。
71 名参与者（56.3%为女性），年龄 60-85 岁，分为三组 - 髋关节手术后患者（21 名 HFS 和 30 名 THA 患者）和对照组（20 名参与者）。在基线和应用体力应激（握力）后记录心电图。采用 3（组）×2（时间）重复测量方差分析和卡方检验进行组间差异检验。
与 HFS 患者相比，THA 患者的体重（p = .002）、体重指数（p = .001）和收缩压（p = .034）更高。与对照组相比，HFS 组的小腿围（p = .009）和舒张压（p = .048）更低。对于心血管参数，HFS 组与对照组在 HR（p = .005）、SDNN（p = .034）和 SD2（p = .012）方面存在显著差异。在两个髋关节手术组之间，无论是在基线还是在应激恢复期间，都没有观察到心血管参数的显著差异。
虽然 HRV 似乎可以很好地区分 HFS 患者和对照组，但需要更多的大样本研究来仔细检查 HFS 和 THA 患者之间心血管特征的相似性和差异。
