Abstract

OBJECTIVE: In polycythaemia vera (PV) and essential thrombocythaemia (ET), the life expectancy of the patients is greatly affected by thrombotic events. An investigation was performed of the potential association of PV/ET, and thrombotic complications with cardiovascular (CV) risk factors, a leukocyte count at the haematological diagnosis > 11.1 G/L, and the JAK2V617F mutation.

PATIENTS AND METHODS: In the period 1998-2011, 128 women with a median age of 62 years were enrolled.

RESULTS: The risk of thrombotic events before the diagnosis was 32.8% (42/128), while in the follow-up period it was 10.2% (13/128). The difference in the probability of thrombosis-free survival between those with at most one CV risk factor and those with two or more CV risk factors was significant (p = 0.005). The presence of two or more CV risk factors (univariate: p = 0.011; multivariate: relative risk: 4.728, 95% CI 1.312-17.040; p = 0.018) significantly increased the risk of thrombosis. Univariate analyses revealed that high blood pressure (p = 0.001), hyperlipidaemia (p = 0.005) and cigarette smoking (p = 0.051) were associated with a significantly higher risk of thrombosis. Analyses of the influence of the leukocyte count (univariate: p = 0.424; multivariate: relative risk: 1.407, 95% CI 0.359-5.507; p = 0.624) and the JAK2V617F mutation (univariate: p = 0.367; multivariate: relative risk: 1.428, 95% CI 0.316-6.460; p = 0.643) on subsequent thrombotic complications resulted in a non-signicant tendency.

CONCLUSIONS: Female patients who display CV risk factors (high blood pressure, hyperlipidaemia and/or cigarette smoking) and PV or ET may well be at a higher risk of thrombotic events and require special consideration as concerns as the prevention and management of thrombotic events.
