Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism. Right ventricular ischemia due to increased right ventricular afterload is believed to be underlying mechanism of elevated troponin values in acute pulmonary embolism, but a paradoxical coronary artery embolism through opened intra-atrial communication is another possible explanation as shown in our case report.
肺栓塞是一种常见的心血管急症，但由于其临床症状不具特异性，仍常被误诊。肌钙蛋白浓度升高与肺栓塞患者更高的发病率和死亡率相关。右心室后负荷增加导致的右心室缺血被认为是急性肺栓塞中肌钙蛋白值升高的潜在机制，但正如我们的病例报告所示，通过开放的心房内交通发生的矛盾性冠状动脉栓塞是另一种可能的解释。
