二尖瓣狭窄患者的血栓和栓塞症发病率超过风湿性心脏病的其他瓣膜疾患,这种情况已有所报导。关于血栓和/或栓塞症发病率较高的原因,据报导认为是由于二尖瓣狭窄患者较之其他瓣膜疾患的患者更易于发生心房纤颤,而心房纤颤所造成的血流扰乱就很容易引起血栓和/或栓塞症。但是对于血栓和/或栓塞症的发病率与凝血纤溶研究,包括二尖瓣狭窄患者的 It has been reported that the incidence of thromboembolism and embolism in patients with mitral stenosis exceeds that of other valvular diseases of rheumatic heart disease. The reason for the higher incidence of thrombosis and / or embolism has been reported to be due to the fact that patients with mitral stenosis are more susceptible to atrial fibrillation than patients with other valvular disorders, and that the disturbance of blood flow caused by atrial fibrillation is very high Easily lead to thrombosis and / or embolism. However, the incidence of thrombosis and / or embolism and coagulation fibrinolysis, including patients with mitral stenosis
