Pulmonary Arterial Hypertension in Connective Tissue Diseases Beyond Systemic Sclerosis

Heart Fail Clin. 2023 Jan;19(1):45-54. doi: 10.1016/j.hfc.2022.08.016.

Abstract

Pulmonary arterial hypertension (PAH) associated with connective tissue disease (CTD) (CTD-PAH) is a devastating condition that may progress rapidly to cause right ventricular dysfunction, resulting in significant morbidity and mortality. The pathobiology, epidemiology, natural history, early diagnosis, and treatment response of PAH associated with scleroderma (SSc-PAH) have been the subjects of intense research efforts over the previous decade. The success of these efforts has resulted in increased awareness and earlier detection of SSc-PAH. Practitioners are less aware of the risk of PAH associated with other CTDs; the aim of this article is to discuss the broader scope of CTD-PAH.

Keywords: Associated pulmonary arterial hypertension; Connective tissue disease; Epidemiology; Mixed connective tissue disease; Pulmonary hypertension; Scleroderma; Screening; Systemic lupus erythematosus.
