Prognosis of Pulmonary Hypertension: The median duration of survival after the diagnosis of primary pulmonary hypertension is 2.8 years, but this figure is highly variable. As a result of new treatments, patients without hemodynamic evidence of right ventricular dysfunction may survive for more than 10 years. The prognosis for patients with secondary pulmonary hypertension depends on the underlying disease, as well as right ventricular function. For instance, patients with COPD and moderate airflow obstruction have a three-year mortality rate of 50 percent after the onset of right ventricular failure. Survival is similarly influenced in patients with interstitial lung disease and pulmonary hypertension.
