Advances in nutritional status of patients with connective tissue-associated pulmonary hypertension

Connective Tissue Disease (CTD) is an autoimmune disease involving connective tissues, including sjogren syndrome (pSS), rheumatoid arthritis (RA), systemic sclerosis (SSc), mixed tissue (MCTD), lupus erythematosus (SLE), etc. [1,2]. Pulmonary Arterial Hypertension (PAH) refers to a pathological condition in which the pulmonary artery pressure rises above certain threshold, causing right heart failure and death [3]. PAH mean Artery Pressure (mPAP) of greater than 25 mmHg wedge (PAWP) less 15mmhg under catheterization (RHC) at rest [4,5]. The only criterion for examining hypertension cardiac catheterization. disease-associated (CTD-PAH) rare complication PAH, characterized by high mortality, venous involvement poor prognosis [6-8].
