1. Pulmonary hypertension is not as rare as previously thought and can be diagnosed using echocardiography. Survival rates decrease significantly as estimated right ventricular systolic pressure increases.
2. While pulmonary hypertension remains largely untreatable, treatment options include pulmonary vasodilator medications, balloon dilation, surgical shunts, and newer interventions like pulmonary artery denervation.
3. Combination drug therapy using multiple pulmonary vasodilators is now the standard of care approach and has been shown in studies to reduce clinical worsening events and improve survival compared to monotherapy. Initial triple oral therapy may provide additional benefits over initial double therapy.
