Prevalence and influencing factors of kinesiophobia in patients with acute myocardial infarction after emergency percutaneous coronary intervention

To investigate the prevalence of kinesiophobia in AMI patients after emergency PCI, analyze its influencing factors, and provide scientific evidence for clinical rehabilitation interventions. A cross-sectional study design was adopted, selecting 320 AMI patients who received PCI treatment in the emergency department of our hospital from January 2022 to December 2024 as study subjects. The Chinese version of the Tampa Scale for Kinesiophobia for Cardiac Patients (TSK-CV), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Numerical Rating Scale (NRS), and Social Support Rating Scale (SSRS) were used to assess patients. Basic information, clinical characteristics, and laboratory examination results of patients were collected. Univariate analysis and multivariable logistic regression analysis were used to explore influencing factors of kinesiophobia. Among the 320 AMI patients, 137 developed kinesiophobia, with a prevalence of 42.8%. Among them, 89 cases (27.8%) had mild kinesiophobia, 38 cases (11.9%) had moderate kinesiophobia, and 10 cases (3.1%) had severe kinesiophobia. Univariate analysis showed that age, sex, education level, marital status, occupation, Killip cardiac function classification, left ventricular ejection fraction, anxiety, depression, pain, and social support were associated with the presence of kinesiophobia (P < 0.05). Multivariable logistic regression analysis showed that age, female sex, cardiac function class III-IV, anxiety, and depression were independent risk factors for kinesiophobia, while social support was a protective factor. The prevalence of kinesiophobia is high in AMI patients after emergency PCI. Age, female sex, cardiac dysfunction, anxiety, and depression are independent risk factors for kinesiophobia, while social support is a protective factor.
