Polycythemia vera is a chronic myeloproliferative neoplasm characterized by abnormal overproduction of red blood cells, resulting in erythrocytosis (1,2). This excess red blood cell production increases hematocrit, the proportion of red blood cells relative to total blood volume, thereby increasing blood viscosity. In the United States, PV affects an estimated 90,000 individuals (2). Elevated blood viscosity associated with uncontrolled hematocrit increases the risk of seriou
