Pulmonary Arterial Hypertension in Indonesia: Current Status and Local Application of International Guidelines

Key Highlights: Pulmonary arterial hypertension (PAH) is a rare progressive subtype of pulmonary hypertension with poor overall prognosis and outcomes.Prompt and accurate diagnosis of PAH remains an unmet challenge in low- and middle-income countries due to poor knowledge about the etiology and pathophysiology of this syndrome. Also, the symptoms and signs of early-stage PAH are usually nonspecific or undetectable in newborn and infants, thus presenting a challenge for physicians to establish early diagnoses of PAH.The challenging factors in low- and middle-income countries, especially Indonesia archipelago are limitations of healthcare infrastructure, limited expertise, lack of awareness, lack of timely PAH screening strategies, poor antenatal care and unpredictable availability of PAH medications.There are no specific national guidelines focusing on diagnostic workup and treatment of PAH in Indonesia. Under-utilization of treatment guidelines and lack of adequate diagnostic treatment facilities have resulted in sub-optimal management of PAH patients in Indonesia.Adherence to international guidelines is an important aspect of PAH management in Indonesia. Updated disease and functional classifications of PAH as per international guidelines along with new research findings on prognostic factors can help in making better management decisions for PAH patients at different stages of the disease.
