Relevance of liver function tests in pulmonary hypertension

Background: Pulmonary hypertension (PH) is a serious limitation of cardiovascular hemodynamics by increased pulmonary vascular resistance. Its prognosis is determined by right ventricular function as defined by right atrial pressure (RAP) and cardiac index (CI). Liver function tests (LFT) are well-established routine parameters. In PH reduced perfusion, congestion due to right heart failure and side effects of therapy with oral anticoagulants or endothelin receptor blockers may cause their elevation. In this study we investigated the prognostic relevance of these parameters for survival in patients with PH and t…
