肺栓塞(pulmonary embolism,PE)是仅次于急性冠状动脉疾病、中风之后的常见心血管疾病[1]。由肺血管阻力增加所致的右心室负荷过重是较大的PE常见的表现[2]。已有研究证实,急性肺动脉压升高可导致心肌缺血甚至右心室梗死,进而引起右心室衰竭甚至死亡[3]。溶栓等治疗能改善PE预
Pulmonary embolism (PE) is a common cardiovascular disease after acute coronary artery disease and stroke [1]. Right ventricular overload due to increased pulmonary vascular resistance is a common manifestation of larger PE [2]. Studies have shown that acute pulmonary hypertension can lead to myocardial ischemia or even right ventricular infarction, which in turn leads to right ventricular failure and even death [3]. Thrombolytic therapy can improve PE pre-treatment
