Abstract
Introduction: The predictive value of the risk stratification scales in elderly patients with IPAH might differ from that in younger. It is unknown whether young and older IPAH patients have the same survival dependence on PAH-specific therapy numbers. The aim of the study was to evaluate the prognostic relevance of risk stratification scales and PAH medication numbers in elderly in comparison with young IPAH patients. Material and methods: 119 patients from a prospective single-center PAH registry were divided on to group I <60 years old (n=89) and group II ≥60 years old (n=30). ESC/ERS, REVEAL, and REVEAL 2.0 risk stratification scores were assessed at baseline, as well as H2FpEF- score and survival at follow-up. Results: During a mean follow-up period of 2.9 years (1.63; 6.0) 42 (35.3%) patients died; at 1, 2, 3, 5, 7, and 10 years survival was 95%, 88.6%, 78.5%, 61.7%, 48.5% and 33.7%, respectively. No survival difference was observed between the two groups despite the use of monotherapy in elderly patients. The best predictive value exhibited the REVEAL in group II (IPAH patients ≥60 years) - AUC 0.73 (0.56-0.91), p = 0.03; and in patients with LHD comorbidities in the entire cohort - AUC 0.73 (0.59-0.87), p<0.009. Factors independently associated with death in the entire cohort were CKD (p=0.01, HR 0.2), the right-to-left ventricle dimension ratio (p=0.0047, HR 5.97), and NT-proBNP >1400 pg/ml (p=0.008, HR 3.18). Conclusion: Risk stratification in elderly IPAH patients requires a fundamentally different approach than that of younger patients, taking into account the initial limitations in physical performance and comorbidities that interfere with current assessment scores. The REVEAL score reliably stratifies patients at any age and LHD comorbidities. The initial monotherapy seems to be reasonable in patients over 60 years. Selection tools for initial combination PAH therapy in older IPAH patients with comorbidities need to be validated in prospective observational studies.
