plexiform lesion in pulmonary hypertension

Plaque-like lesions in pulmonary arterial hypertension (PAH) are an uncommon but severe pathological feature that can significantly affect patient outcomes. These lesions typically present as irregular intimal hyperplasia within the pulmonary arteries, potentially leading to increased pulmonary arterial pressure and exacerbating the cardiac workload.

Upon thorough analysis, the development of plaque-like lesions is associated with a multitude of factors, including genetic predispositions, autoimmune disorders, and exposure to medications or toxins. The presence of these lesions often indicates a more advanced stage of PAH, as they can cause pulmonary vascular resistance to rise, resulting in right ventricular hypertrophy and dysfunction. Furthermore, due to the complexity and heterogeneity of plaque-like lesions, their management is challenging and may necessitate more aggressive interventions, such as targeted pharmacotherapy or lung transplantation.

For patients with PAH who also have plaque-like lesions, it is crucial to avoid vigorous physical activity and excessive fatigue to lessen the strain on the heart. Regular monitoring of blood pressure and cardiac function is essential, along with timely adjustments to the treatment plan. Above all, patients should adhere to a standardized treatment regimen under medical supervision, avoiding the use or discontinuation of medication without guidance. Should symptoms such as shortness of breath or chest pain worsen, immediate medical attention is imperative.
