Review of Functional Status and Hemodynamic Parameters in Patients Diagnosed with Chronic Thromboembolic Pulmonary Hypertension (CTEPH) With and Without Antiphospholipid Syndrome (APLS).

Pulmonary hypertension is a hemodynamic state defined by a mean pulmonary arterial pressure >20 mmHg and a pulmonary vascular resistance ≥3 WU, subdivided into 5 groups. Chronic Thromboembolic Pulmonary Hypertension (CTEPH) corresponds to group 4. The antiphospholipid syndrome is one of the most associated thrombophilia, with a prevalence of CTEPH of 2%-50%.
