Pulmonary Hypertension

Pulmonary hypertension (PH) is a serious medical condition characterized by abnormally high blood pressure in the pulmonary arteries, which supply blood to the lungs. This increased pressure forces the right side of the heart to work harder, potentially leading to right ventricular hypertrophy, right heart failure, and other severe complications if untreated. PH can result from underlying heart or lung diseases, such as cor pulmonale, chronic obstructive pulmonary disease (COPD), congenital heart defects, connective tissue disorders, and pulmonary embolism. It may also be associated with genetic factors, liver disease, or idiopathic causes. Common symptoms include dyspnea, fatigue, chest pain, edema in the legs and feet, dizziness, and palpitations. Diagnosis is confirmed when resting mean pulmonary arterial pressure exceeds 20 mmHg and pulmonary vascular resistance is above 3 Wood units. PH affects individuals across all ages, with higher prevalence in women, non-Hispanic Black populations, and those aged 75 and older. Early detection and management are crucial for improving prognosis and quality of life.
