Barriers and facilitators to physical activity after transcatheter aortic valve replacement: A mixed-methods study

Area of Science:

• Cardiology
• Rehabilitation Medicine
• Behavioral Science

Background:

• Transcatheter aortic valve replacement (TAVR) improves survival but physical activity post-procedure is often suboptimal.
• Understanding factors influencing post-TAVR physical activity is crucial for patient recovery and long-term health.

Purpose of the Study:

• To evaluate physical activity levels in patients after TAVR.
• To identify barriers and facilitators impacting physical activity participation post-TAVR.

Main Methods:

• A mixed-methods study combining quantitative surveys (IPAQ-SF) and qualitative interviews guided by Fogg's behavior model.
• 195 patients who underwent TAVR in Shanghai were assessed.
• Poisson regression identified preliminary factors, followed by targeted interviews to explore behavioral determinants.

Main Results:

• A significant majority (93.33%) of post-TAVR patients reported a lack of regular physical activity.
• Fourteen barriers and facilitators were identified, categorized under motivation, ability, and triggers.
• Key factors included health expectations, kinesiophobia, self-regulation challenges, and the influence of social and environmental support.

Conclusions:

• Adherence to regular physical activity remains low among patients following TAVR.
• Future interventions should focus on enhancing patient motivation, improving physical activity capability, and leveraging appropriate environmental and social triggers.
