Pulmonary hypertension is one of the most common causes of dyspenea or shortness of breath. K. Akaya Smith, MD, a pulmonologist at the Hospital of the University of Pennsylvania (HUP) discusses why. Pulmonary hypertension (PH) comprises a spectrum of diseases that can lead to the dangerous onset of shortness of breath. PH is a condition of abnormally high blood pressure in the lungs, typically caused by common heart and lung diseases like congestive heart failure (CHF) or emphysema. Penn Medicine offers the most effective treatments available to slow the progression of PH, and even reverse some of the damage to the lungs and heart.
