目的分析不同肺动脉栓塞指数(PI)急性肺血栓栓塞症(PTE)患者的临床表现。方法连续选择61例确诊PTE患者,根据他们的影像学表现,分别计算出PI指数,并统计他们急性期主要症状和体征指标。结果61例PTE患者的影像学平均PI指数为(43.64±12.72),高PI组(PI≥43.64;29例)的呼吸困难、胸痛、咳嗽以及呼吸、心率和体温等症状和体征指标均明显高于低PI组(PI<43.64;32例),而前者的平均收缩压和舒张压明显低于后者(P均<0.01～0.05)。结论高PI急性肺血栓栓塞症患者发病期间呼吸、循环系统症状和体征表现更为突出。
Objective To analyze the clinical manifestations of patients with pulmonary embolism (PTE) of different pulmonary embolism index (PI). Methods Sixty-one consecutive patients with PTE were selected. Based on their imaging findings, PIs were calculated and their main symptoms and signs were analyzed. Results The average PI of 61 patients with PTE was (43.64 ± 12.72). The symptoms and signs of chest pain, cough, respiration, heart rate and body temperature in high PI group (PI≥43.64; 29 cases) were significantly higher In the low PI group (PI <43.64; 32 cases), the mean systolic and diastolic blood pressures of the former were significantly lower than those of the latter (P <0.01-0.05). Conclusion The respiratory, circulatory symptoms and signs of patients with high PI acute pulmonary thromboembolism are more prominent.
