Pulmonary Vascular Diseases secondary to Conditions Affecting the Lung Parenchyma

Pulmonary vascular diseases refer to conditions that affect the blood vessels in the lungs. When the lung tissue (parenchyma) becomes damaged or inflamed due to diseases like pneumonia, chronic obstructive pulmonary disease (COPD), or interstitial lung disease, it can lead to problems with blood flow in the lungs. This can cause increased pressure in the pulmonary arteries, leading to pulmonary hypertension. In simple terms, if the lung tissue is not healthy, it can strain the blood vessels, making it harder for the heart to pump blood through the lungs effectively.
