Pulmonary Vascular Disease in simple form can be defined as any medical condition that affects the blood vessels between the heart and lungs. The process of oxygenation of blood takes place in the following way. Blood deprived of oxygen comes from the tissues of the body through the veins to the right side of the heart which then pumps this blood through the pulmonary arteries to the lungs which oxygenates the blood. The blood then returns to the left side of the heart where it goes to various parts of the body through the arteries. Any sort of blockage or damage to this whole path of the blood causes pulmonary vascular disease.
What are the causes of pulmonary vascular disease?
Causes of pulmonary vascular disease are variable and depend on the blood vessels in the lungs which are affected. Pulmonary Vascular Disease is divided into various categories which are as follows:
- Pulmonary Arterial Hypertension: This is a medical condition in which there is increased blood pressure in the pulmonary arteries. This disease is usually caused by lung diseases, autoimmune diseases, or heart failure.
- Pulmonary Venous Hypertension: This is a medical condition in which there is increased blood pressure in the pulmonary veins. This condition is usually caused by congestive heart failure.
- Pulmonary Embolism: This is a medical condition in which a blood clot which breaks from the deep vein gets pumped into the lungs from the heart.
- Chronic Thromboembolic Disease: In rare instances, pulmonary embolism is not reabsorbed by the body and instead causes other vessels to get diseased.
