Introduction: Pulmonary hypertension (PH) is a serious complication in connective tissue disease (CTD), although multiple causes can be the source of it. Therefore, it is essential to establish an accurate diagnosis to determine the cause of HP. Early detection algorithms are aimed to diagnose PH in patients with CTD in less advanced disease. Objectives: 1) To detect the presence of pulmonary hypertension (PH) in a population diagnosed with CTD by an early detection algorithm. 2) To diagnose Pulmonary arterial hypertension (PAH) associated to CTD. Materials and Methods: It's a descriptive, prospective study. Adult patients diagnosed with symptomatic CTD or symptomatic and asymptomatic systemic sclerosis, mixed connective tissue disease (MCTD) in the setting of rheumatologic control were included. Those patients with high clinical and echocardiographic suspicion of PH were catheterized (CCD). Results: 90 patients, 82 women (91%) were included, with a median age of 52 years. Fifty-flour (60%) corresponding to Systemic sclerosis, 18 (20%) to rheumatoid arthritis, 8 (9%) to MCTD, 8 (9%) to systemic lupus erythematosus, 1 (1%) to Sjögren and 1(1%) to polymyositis. Dyspnea was referred in 50 patients (67%); 12 patients (13%) had high presumption of HP and underwent a CCD, confirming the diagnosis of HP in 9 (10%). Sever belonged to PH Group I and 2 to group II. PH group I patients were distributed according to functional class (FC), as follows: 1 FC III, 5 FC II and 1 FC I. Conclusions: The used algorithm allows early PAH diagnosis in CTD.
