Key result
Functional limitations in valvular heart disease correlate with HF stage, affecting self-care in ~83%.
Why the study?
Traditional assessment methods for valvular heart defects inadequately reflect daily activity and social participation, making the application of International Classification of Functioning, Disability and Health (ICF) domains promising for identifying functional and rehabilitation profiles.
Cross-Sectional (n=13,652)
No
ICF-based functional profiling in patients with valvular heart disease identifies distinct rehabilitation profiles linked to heart failure severity and clinical comorbidities, enabling more structured medical-social assessment and rehabilitation planning.
May support ICF-based rehab planning in valvular disease; leaves open prospective validation of profiles before practice change.
BACKGROUND: In valvular heart defects, expert assessment must consider not only clinical severity but also how cardiovascular dysfunction affects self-care, mobility, and work. Traditional methods inadequately reflect daily activity and social participation, so applying International Classification of Functioning, Disability and Health (ICF) domains as a framework for functional profiling is promising. AIM: To study the structure of functional limitations in disabled persons with valvular heart defects and identify expert-rehabilitation profiles based on ICF domains. METHODS: A single-center retrospective cross-sectional study of medical and social expertise data from 2017–2024 was performed. First, the structure of limitations by categories and severity grades was analyzed. Second, in 557 examinees, associations between clinical-functional parameters and limitation grades were assessed, followed by ICF domain comparison and cluster analysis. RESULTS: Among 13,652 disabled persons, grade 1 limitations predominated: self-car (82.6%), mobility (75.9%), work (74.4%). Grade 2 limitations were most frequent for work (20.9%). Limitation severity correlated with chronic heart failure stage (χ²=462.2–890.8; p 0.001) and NYHA class (χ²=333.7–545.5; p 0.001). Grade 2 was associated with chronic heart failure IIB, atrial fibrillation, ischemic heart disease, the absence of surgical correction, a lower left ventricular ejection fraction, and a higher peak inspiratory pressure. Cluster analysis revealed three profiles differing in impairment severity and functional limitations. CONCLUSION: Functional limitations in valvular heart defects are multifactorial. ICF-based profiling enables a shift from isolated category descriptions to integrated profiles, facilitating structured assessment and rehabilitation planning.

Smotrina et al. (2026) conducted a cross-sectional in Valvular heart disease (n=13,652). ICF-based functional profiling and clinical-functional parameters (chronic heart failure stage, NYHA class) was evaluated on Structure and severity grades of functional limitations across ICF domains (self-care, mobility, work) (p=<0.001). ICF-based profiling in valvular heart disease showed predominating grade 1 limitations in self-care (82.6%), mobility (75.9%), and work (74.4%), correlating with heart failure stage (p<0.001).
