肺栓塞是病死率较高的疾病之一,病死率因病情严重程度而异。影响肺栓塞患者预后的因素众多,研究预测肺栓塞患者临床结果的因素有助于优化肺栓塞的治疗。血流动力学不稳定(动脉收缩压低于90mmHg或休克)(1mmHg=0.133kPa)、右心功能不全(右心室扩大、收缩期室间隔反向运动)、心电图异常、血浆心肌肌钙蛋白水平升高和血浆脑利钠肽水平升高是肺栓塞患者预后不良的预测因素。除了血流动力学不稳定采用的收缩压判断值(低于90mmHg)之外,其他预测因素的判断标准各研究均不一致,使其临床应用受到限制。
Pulmonary embolism is one of the more serious cases of mortality, mortality varies with the severity of the disease. Many factors affect the prognosis of patients with pulmonary embolism, the study predicts the clinical outcome of patients with pulmonary embolism factors contribute to the optimization of pulmonary embolism. Hemodynamic instability (arterial systolic blood pressure less than 90 mm Hg or shock) (1 mm Hg = 0.133 kPa), right ventricular dysfunction (right ventricular enlargement, reverse ventricular septal systole), abnormal electrocardiogram, and elevated plasma cardiac troponin levels Elevated levels of plasma and brain natriuretic peptide are predictors of poor prognosis in patients with pulmonary embolism. In addition to judging the value of systolic blood pressure (less than 90 mm Hg) for hemodynamic instability, the criteria for other predictors were inconsistent in all studies, limiting their clinical utility.
