What happens to life expectancy with pulmonary hypertension if left untreated?
Without treatment, the outlook for pulmonary arterial hypertension is quite serious. For idiopathic PAH (when there's no known cause), people who don't receive treatment typically live about two to three years after diagnosis.
If chronic thromboembolic pulmonary hypertension (CTEPH) is not treated and continues to progress, life expectancy is generally one to three years.
This is why getting proper treatment is so important. Modern PAH treatments have significantly improved life expectancy by several years compared to these untreated outcomes. Treatment can help you live longer and feel better, so working with your healthcare team to find the right approach for you is essential.
