Abstract

Aim. To assess the clinical course of the disease and the features of the treatment goals achievement in patients with IPAH and inoperable CTEPH depending on gender and age at the time of diagnosis verification.

Materials and methods. The study included 88 patients with IPAH and 38 patients with inoperable CTEPH with a PAWP <12 mm Hg and the duration of PAH-specific therapy treatment more than 12 months. IPAH/CTEPH patients were divided into groups depending on age at the time of diagnosis verification: age <50 years (n=69)/ >50 years (n=57), and gender: 106 women/20 men.

Results. Patients with age >50 years at the time of diagnosis verification have significantly more severe functional class (WHO). In IPAH/CTEPH male patients a significant hemodynamic disorder also as significantly higher level of NT-proBNP at the time of diagnosis verification were observed. In men with IPAH/CTEPH and patients aged >50 years more pronounced deterioration of right ventricular systolic function was observed (ECHO). Patients with IPAH younger than 50 years were significantly more likely to achieve the treatment goals by the median 26.5 months of treatment compared to the patients aged >50 years (21% vs 6.45%). Men with IPAH/CTEPH were significantly more likely to have a high risk of death (90%) at baseline compared to the women (61%).

Conclusion. IPAH/inoperable CTEPH patients with male sex, as well as the age 50 years and older at the time of diagnosis verification, compared with younger ones, are associated with a less favorable course of the disease.
