BACKGROUND
Thrombosis is the most important cardiovascular complication of classical myeloproliferative disorders (MPDs). Endothelial dysfunction (ED) is known to play a major role in the mechanism of thrombophilia in MPDs.
METHODS
Endothelial dysfunction and its associations with other parameters were investigated. A total of 18 patients with polycythemia vera (PV), 24 with essential thrombocytosis (ET), 7 with primary myelofibrosis (PMF), and 30 healthy patients as a control group were included in the study. To assess the ED, flow-mediated dilatation (FMD) measurements were used.
RESULTS
The FMD (%) result showing ED was determined as 9.9 (0.0-21.6) in the patients with PV, 7.3 (0.0-30.5) in patients with ET, 7.5 (0.0-18.0) in patients with PMF, and 13.9 (6.2-26.7) in the control group. The FMD (%) was markedly impaired in all patients with MPD compared to the control patients (7.8 [0.0-30.5] vs 13.9 [6.15-26.8], P = .02). According to the disease subtypes, FMD (%) was significantly lower in the ET group than in the control group ( P = .01).
CONCLUSION
Endothelial function was assessed in patients with MPD having FMD and was determined to demonstrate ED. Lower FMD was associated with older age, leukocytosis, thrombocytosis, and thrombosis history.
背景
血栓形成是经典骨髓增殖性疾病（MPD）最重要的心血管并发症。已知内皮功能障碍（ED）在MPD的血栓形成机制中起主要作用。
方法
研究内皮功能障碍及其与其他参数的关联。本研究纳入了18例真性红细胞增多症（PV）患者、24例原发性血小板增多症（ET）患者、7例原发性骨髓纤维化（PMF）患者以及30例健康患者作为对照组。采用血流介导的血管舒张（FMD）测量来评估内皮功能障碍。
结果
PV患者中显示内皮功能障碍的FMD（%）结果为9.9（0.0 - 21.6），ET患者为7.3（0.0 - 30.5），PMF患者为7.5（0.0 - 18.0），对照组为13.9（6.2 - 26.7）。与对照患者相比，所有MPD患者的FMD（%）均明显受损（7.8 [0.0 - 30.5] 对 13.9 [6.15 - 26.8]，P = 0.02）。根据疾病亚型，ET组的FMD（%）显著低于对照组（P = 0.01）。
结论
对采用FMD评估的MPD患者的内皮功能进行了评估，结果显示存在内皮功能障碍。较低的FMD与年龄较大、白细胞增多、血小板增多和有血栓形成病史相关。
