Kinesiophobia and its associated factors among patients after transcatheter aortic valve replacement: a cross-sectional study based on latent profile analysis.

BACKGROUND

Kinesiophobia, a significant barrier to daily activities, may contribute to adverse outcomes in patients following transcatheter aortic valve replacement (TAVR). This study aimed to assess the prevalence and identify factors associated with kinesiophobia in post-TAVR patients.

METHODS

From January to December 2023, a cross-sectional survey was conducted using a convenience sampling method, involving patients from the cardiology department of a hospital in China. The study utilized several instruments: a general information questionnaire, the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), the Lubben Social Network Scale-6 (LSNS-6), the Exercise Social Support Scale (ESSS), the Physical Activity Rank Scale (PARS-3) and the Self-Efficacy for Exercise Scale (SEE). Latent profile analysis (LPA) was performed to classify patients into latent subgroups based on their levels of kinesiophobia. Additionally, multivariate logistic regression analysis was employed to identify the influencing factors of kinesiophobia among patients with varying characteristics.

RESULTS

This study included a total of 290 participants. Based on the assessment of kinesiophobia, three profile models were identified by LPA: a high-level kinesiophobia group (21 participants, 7.2%), a moderate-level kinesiophobia group (189 participants, 65.2%), and a low-level kinesiophobia group (80 participants, 27.6%). Factors influencing the levels of kinesiophobia across the three latent profiles included education level, aortic stenosis flow type, number of comorbidities, postoperative NYHA cardiac function classification, preoperative physical activity level, social networks, and exercise self-efficacy.

CONCLUSION

Kinesiophobia levels in patients after transcatheter aortic valve replacement exhibit significant heterogeneity, primarily influenced by factors such as education level, aortic stenosis flow type, number of comorbidities, postoperative NYHA cardiac function classification, preoperative physical activity level, social networks, and exercise self-efficacy. In the future, healthcare professionals should identify postoperative patients at risk for kinesiophobia and consider the multifaceted factors affecting this condition. It is essential to encourage and stimulate patients' thoughts about exercise and to provide targeted intervention strategies to reduce their levels of postoperative kinesiophobia.
