Treatment of Pulmonary Hypertension
Classification and Initial Assessment
- The European Respiratory Society recommends that right heart catheterization is essential to confirm the diagnosis of PAH and guide treatment decisions 2, 3
- The European Respiratory Society suggests that vasoreactivity testing is recommended in patients with idiopathic PAH, heritable PAH, and drug-induced PAH to identify those who may respond to calcium channel blockers 2, 3
- Risk assessment using clinical parameters, exercise capacity, biomarkers, and imaging is crucial to guide therapy selection and monitor treatment response, as recommended by the European Heart Journal and European Respiratory Journal 4, 1
Treatment Based on PH Classification
Group 1: Pulmonary Arterial Hypertension (PAH)
- The European Respiratory Journal recommends initial oral combination therapy for treatment-naïve patients with low or intermediate risk 2, 3
- For high-risk patients, the European Respiratory Journal recommends intravenous prostacyclin analogues, such as epoprostenol, as they improve survival 6
- The European Respiratory Journal suggests that sequential combination therapy targeting multiple pathways is recommended for patients with inadequate response to initial therapy 2, 3
Group 4: Chronic Thromboembolic Pulmonary Hypertension (CTEPH)
- The European Respiratory Journal recommends surgical pulmonary endarterectomy in deep hypothermia circulatory arrest for operable patients 1, 2, 3
- Riociguat is recommended for inoperable CTEPH or persistent/recurrent PH after surgery, as suggested by the European Respiratory Journal 1
- The European Respiratory Journal recommends lifelong anticoagulation for all CTEPH patients 1
Supportive Care and General Measures
- The European Respiratory Journal recommends diuretics for fluid overload management with careful monitoring of electrolytes and renal function, although the citation is from Praxis Medical Insights 6
- Oxygen supplementation to maintain saturation >90% is recommended by Praxis Medical Insights 6
- Supervised exercise training is recommended for physically deconditioned patients, as suggested by Praxis Medical Insights 5, 6
- Pregnancy should be avoided in PAH patients due to 30-50% mortality risk, as recommended by the European Respiratory Journal and Praxis Medical Insights 2, 3, 5
Monitoring and Follow-up
- Regular follow-up assessments every 3-6 months in stable patients are recommended by the European Heart Journal and European Respiratory Journal 4, 2, 3
- The European Heart Journal suggests that treatment goal is to achieve and maintain low-risk status (WHO FC I-II, good exercise capacity, preserved RV function) 4, 5
- Consider lung transplantation for patients with inadequate response to maximal medical therapy, as recommended by Praxis Medical Insights 6
