Objective:To explore the developmental trajectory and influencing factors of kinesiophobia in patients undergoing percutaneous coronary intervention (PCI) .Methods:By convenient sampling, totally 217 patients undergoing PCI who enrolled from two tertiary hospitals in Guangdong Province from March 2022 to July 2023. The demographic data of the patients was collected , and kinesiophobia was measured using the Tampa scale for kinesiophobia heart(TSK-SV-Heart) at one day pre-discharge, 2 weeks, 1 month, and 4 months post-discharge. Data analysis was conducted using SPSS 25.0 and Mplus 8.7 softwares. Growth mixture modelling, chi-square test, and polynomial Logistic regression were used for data processing and analysis.Results:Three different kinesiophobia trajectory classes were identified in patients within 4 months after PCI: sustained high level of kinesiophobia group (C1 group, 22.6%(49/217)), moderate level of kinesiophobia with a rapid decrease group (C2 group, 47.4%(103/217)), and rapid decrease of kinesiophobia followed an increase group (C3 group, 30.0%(65/217)). Polynomial Logistic regression results showed that, females ( B=1.136, OR=3.113, 95% CI=1.155-8.389) , patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=1.135, OR=3.112, 95% CI=1.380-7.017) were more likely to develop into the C1 compared with the C2 group. Compared with the C3 group, patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=3.322, OR=27.712, 95% CI=5.251-146.244), and patients with coronary heart disease(CHD) more than two years ( B=3.855, OR=47.250, 95% CI=2.146-1 040.535)were more likely to develop into the C1 group. Compared with the C3 group, patients with NYHA Ⅱ/Killip class Ⅱ or above ( B=-2.187, OR=0.112, 95% CI=0.022-0.565), patients with three or more comorbidities ( B=-2.711, OR=0.066, 95% CI=0.008-0.528), and patients with CHD more than two years ( B=-2.376, OR=0.093, 95% CI=0.011-0.783) were more likely to develop into the C2 group. Conclusion:Kinesiophobia level in patients undergoing PCI presents a curvilinear decrease within 4 months after PCI.Different kinesiophobia trajectory classes can be observed. Sex, NYHA/Killip class, course of CHD, and comorbidity affect the development trajectory of different subgroups.
