Pulmonary hypertension is a group of clinicopathophysiological syndromes in which the mean pulmonary artery pressure measured by the right heart catheter in the resting state is ≥ 25 mmHg due to various causes. A variety of rheumatic diseases can cause pulmonary hypertension, such as scleroderma and systemic lupus erythematosus.
