The Importance of Rv – Pa Coupling in the 1-Year Follow-Up of Patients Living at High Altitude and Initiating Treatment With a Diagnosis of Pulmonary Hypertension
Abstract
Giriş ve Amaç: Pulmoner hipertansiyon (PH), ortalama pulmoner arter basıncının (PAB) artışı ile karakterize, mortalite riski yüksek, tüm yaş gruplarını etkileyebilen önemli bir sağlık sorunudur. Çalışmamızda Doğu Anadolu bölgesinde yaşayıp kliniğimizde takip edilen hastaların noninvaziv RA-PV coupling (eşleşmesi) ile değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Van YYÜ Dursun Odabaş Tıp merkezinde Ocak 2020 – Nisan 2024 tarihleri arasında PH tanısı almış ve takibi yapılmış Grup I ve Grup IV 100 hasta retrospektif olarak değerlendirilmiştir. Hastaların yaşları, demografik verileri, cinsiyetleri, boy ve kilo ölçümleri, ek hastalıkları, sigara kullanıp kullanmama durumları, Dünya Sağlık Örgütü Fonksiyonel Kapasite (DSÖ-FK) sınıflaması, transtorasik ekokardiyografi (TTE) bulguları, 6 dakika yürüme testi (6DYT), kan değerleri, aldıkları tedaviler, sağ kalım süreleri, tanı ve takip aşamasındaki risk durumları kaydedilmiştir. Bulgular: Hastaların 86'sı (%86,0) kadın, 14'ü (%14,0) erkekti, yaş ortalaması 49,04±17,09 yıldı. Hastaların 81'i (%81,0) Grup I, 19'u (%19,0) Grup IV'te yer almaktadır. Hastaların ortalama sağ kalım süresi 50,19±153,60 gün olup 12'si (%12,0) ex olmuştu. Ex olan hastaların TAPSE/sPAB değerleri sağ olan hastalara göre istatiksel olarak anlamlı şekilde daha düşük bulundu (p<0,05). ROC eğrisi analizinde ilk vizitteki TAPSE/sPAB oranı 0,20 mm/mmHg kestirim değeriyle, %66,7 duyarlılık ve %71,3 spesifikle mortaliteyi öngörmekteydi. Tartışma ve Sonuç: Çalışmamızda, TAPSE/sPAB oranının yüksek rakımda yaşayan hastalarda prognoz belirleyici bir parametre olup olmadığı değerlendirilmiştir. Çalışmada ilk vizitteki TAPSE/sPAB oranının mortaliteyi öngörmede etkili olduğu bulunmuştur. TAPSE/sPAB oranı, takiplerde risk sınıflaması ile güçlü bir korelasyon göstermiştir ve bu oranı dikkate almak, PH hastalarının yönetiminde önemli bir rol oynamaktadır.
Introduction and Purpose: Pulmonary hypertension (PH) is an important health problem that is characterized by an increase in mean pulmonary artery pressure (PAP), has a high risk of mortality, and can affect all age groups. Our study aimed to evaluate patients living in the Eastern Anatolia region and followed in our clinic using noninvasive RA-PV coupling. Materials and Methods: 100 Group I and Group IV patients who were diagnosed with PH and followed up at Van YYÜ Dursun Odabaş Medical Center between January 2020 and April 2024 were evaluated retrospectively. Patients' ages, demographic data, gender, height and weight measurements, comorbidities, smoking status, World Health Organization Functional Capacity (WHO-FC) classification, transthoracic echocardiography (TTE) findings, 6-minute walk test (6MWT), blood values. The treatments they received, survival times, and risk situations during diagnosis and follow-up were recorded. Findings: 86 (86.0%) of the patients were female, 14 (14.0%) were male, the average age was 49.04±17.09 years. 81 (81.0%) of the patients were Group I, 19 patients (19.0%) are in Group IV. The average survival time of the patients was 50.19±153.60 days and 12 of them (12.0%) died. TAPSE/sPAP values of ex patients were found to be statistically significantly lower than alive patients (p<0.05). In ROC curve analysis, the TAPSE/sPAP ratio at the first visit predicted mortality with a cutoff value of 0.20 mm/mmHg, 66.7% sensitivity and 71.3% specificity. Discussion and Conclusion: In our study, we evaluated whether the TAPSE/sPAP ratio is a prognostic parameter in patients living at high altitudes. In the study, it was found that the TAPSE/sPAP ratio at the first visit was effective in predicting mortality. The TAPSE/sPAP ratio has shown a strong correlation with risk stratification during follow-ups, and taking this ratio into account plays an important role in the management of PH patients.
