What causes pulmonary hypertension

First, genetic factors: familial pulmonary hypertension accounts for at least 6% of all pulmonary hypertension. Family studies show that the genetic type is autosomal dominant.

Second, immune factors: immune regulation may be involved in the pathological process of pulmonary hypertension. The level of antinuclear antibody increased significantly in 29% of patients with pulmonary hypertension, but there was no specific antibody for connective tissue disease.

Third, pulmonary vascular endothelial dysfunction: pulmonary vasoconstriction and relaxation are jointly regulated by the contraction and relaxation factors secreted by pulmonary vascular endothelium. Due to the imbalance of factor expression, pulmonary vessels are in a state of contraction, resulting in pulmonary hypertension.
