To evaluate post-transcatheter aortic valve replacement (TAVR) physical activity and explore the factors influencing participation.
A quantitatively driven sequential explanatory mixed-methods study was performed from October 2021 to February 2022 in Shanghai, China.
The study sample comprised 195 patients who underwent TAVR (58.46% men, mean age = 74.38 years.
A cross-sectional survey was conducted to assess the extent of physical activity maintenance after TAVR via the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Preliminary factors were identified via Poisson regression. Subsequently, Fogg's behaviour model-guided targeted qualitative interviews were conducted to confirm and expand on barriers and facilitators to physical activity engagement.
93.33% of post-TAVR patients lacked regular physical activity. Fourteen barriers and facilitators were identified and grouped into motivation (health expectation, social belonging, feeling after physical activity, kinesiophobia), ability (complex forms of physical activity, misperceptions, scheduling conflicts, traffic and distance, self-regulation), and triggers (surroundings and environment, peer and family support, professional support, mobile health, internalization of exercise habits).
The study findings indicate low adherence to regular physical activity among patients post-TAVR. Intervention strategies that increase patients' motivation and ability to perform physical activity and provide appropriate triggers should be further developed.
评估经导管主动脉瓣置换术（TAVR）后的身体活动情况，并探讨影响参与度的因素。
2021年10月至2022年2月在中国上海进行了一项定量驱动的顺序解释性混合方法研究。
研究样本包括195例行TAVR的患者（男性占58.46%，平均年龄=74.38岁）。
通过国际身体活动问卷简表（IPAQ-SF）进行横断面调查，以评估TAVR后身体活动维持的程度。通过泊松回归确定初步因素。随后，进行了以福格行为模型为指导的针对性定性访谈，以确认并扩展身体活动参与的障碍和促进因素。
93.33%的TAVR术后患者缺乏规律的身体活动。确定了14个障碍和促进因素，并将其分为动机（健康期望、社会归属感、身体活动后的感受、运动恐惧）、能力（身体活动的复杂形式、误解、日程冲突、交通和距离、自我调节）和触发因素（周围环境、同伴和家庭支持、专业支持、移动健康、运动习惯的内化）。
研究结果表明TAVR术后患者对规律身体活动的依从性较低。应进一步制定提高患者进行身体活动的动机和能力并提供适当触发因素的干预策略。
