Key result
Higher Pittsburgh Sleep Quality Index scores (OR 1.563), lower self-efficacy, and fewer 30-second chair stands were significantly associated with a lower quality of life in patients following TAVR.
Why the study?
Variation in post-TAVR quality of life across patient groups warrants examination to identify distinct profiles and understand contributing factors.

Post-TAVR patients exhibit significant heterogeneity in quality of life, which is strongly influenced by modifiable factors such as sleep quality, self-efficacy, and lower limb muscle strength.
BACKGROUND: The prevalence of aortic valve stenosis is on the rise, primarily due to an aging population. Transcatheter Aortic Valve Replacement (TAVR) has emerged as an effective treatment option, especially for patients at high surgical risk. However, the variation in post-TAVR quality of life across patient groups warrants further examination to understand the contributing factors. OBJECTIVE: This study aims to evaluate the quality of life in patients post-TAVR, characterize distinct patient group profiles, and identify key factors that influence their quality of life. METHODS: From July 2023 to September 2024, 215 TAVR patients were recruited via convenience sampling. Data on sociodemographics and quality of life were gathered using the TAVR-specific quality of life scale. Latent variable growth modeling helped identify quality of life categories and predict influencing factors. RESULTS: Three categories of TAVR patients were identified based on quality of life: the "High quality of life-high health status" group, the "Medium quality of life-intermediate health" group, and the "Low quality of life-low health status" group. Logistic regression analysis revealed that sleep quality, self-efficacy, and performance on the 30-s chair sit-to-stand test were significant predictors of quality of life. CONCLUSION: There is considerable variability in the quality of life among TAVR patients. Tailored health management strategies based on specific patient profiles can potentially improve outcomes in these populations.

Tang et al. (2025) conducted a cross-sectional in Post-Transcatheter Aortic Valve Replacement (TAVR) (n=215). Pittsburgh Sleep Quality Index (PSQI) score vs. Lower PSQI score (better sleep quality) was evaluated on Classification into Low quality of life group versus High quality of life group (OR 1.563, 95% CI 1.236-1.979, p=<0.001). Higher Pittsburgh Sleep Quality Index scores (OR 1.563), lower self-efficacy, and fewer 30-second chair stands were significantly associated with a lower quality of life in patients following TAVR.
