Endothelial-Derived Microvesicles From Andean Highlanders With Excessive Erythrocytosis Induce a Deleterious Cardiomyocyte Phenotype

Excessive erythrocytosis (EE), defined as Hb ≥21 g/dL in men and ≥19 g/dL in women, is a pathologic consequence of residing at high altitude (>2500 m) and is common in Andean highlanders. EE is associated with increased cardiovascular risk and cardiac dysfunction. Specifically, EE has been linked to congestive heart failure as well as right ventricular hypertrophy in high altitude dwellers.
