It may also result in the overproduction of white blood cells and platelets. The increase in blood cells makes the blood thicker, leading to strokes or tissue and organ damage. PV patients have an excellent chance of living out a normal life span if properly monitored and treated. Polycythemia Vera Life Expectancy . The rate of grade 1 reticulin fibrosis in PV at diagnosis ranges from 14% 41 to 30%, 42 and this does not imply per se a diagnosis of myelofibrosis.
