Pulmonary hypertension (PH) is a complex condition that can stem from a variety of underlying causes. These include, but are not limited to:
* Lung Diseases: Conditions such as chronic bronchitis, asthma, and Chronic Obstructive Pulmonary Disease (COPD) can lead to the development of PH.
* Sleep Apnea: Intermittent cessation of breathing during sleep can cause impaired oxygenation. If left unaddressed, this can contribute to the development of PH and may also be associated with other cardiovascular complications.
* Heart Diseases: Certain cardiac conditions, including mitral stenosis and various myocardial diseases, are known causes of PH.
* Systemic and Other Conditions: Diseases like rheumatoid arthritis and pulmonary embolism can also induce PH.
* Congenital Heart Defects: Eisenmenger syndrome, a form of congenital heart disease, is a significant cause of PH. It commonly involves a large ventricular septal defect (a hole between the two lower heart chambers, or ventricles). This defect leads to an abnormal shunting of blood, where oxygen-rich blood mixes with oxygen-poor blood and is recirculated to the lungs instead of the rest of the body. This continuous overload significantly increases pressure within the pulmonary arteries, culminating in pulmonary hypertension.
