Hemodynamic Changes in Hyperthyroidism-Related Pulmonary Hypertension: A Prospective Echocardiographic Study

Abstract

In patients with hyperthyroidism and normal LV systolic function, up to 47% had PHT due to either PAH with increased CO (70%) or PVH with elevated LV filling pressure (30%). Most importantly, hyperthyroidism-related PHT was largely asymptomatic and reversible after restoration to a euthyroid state.
