摘  要:目的 探讨阿替普酶100rag/2h溶栓方案治疗急性肺动脉血栓栓塞症的疗效和安全性,并随访观察治疗后肺栓塞复发和慢性血栓栓塞性肺高血压(CTEPH)等并发症的发生情况。方法前瞻性设计观察并记录43例连续入院的中高危急性肺栓塞患者接受100mg/2h阿替普酶溶栓治疗前后的临床资料及并发症,并对患者进行门诊及电话随访。平均随访时间为(15.6-4-11.4)个月。随访研究终点为肺栓塞复发、肺栓塞所致死亡及新发CTEPH。结果与溶栓前比较,溶栓后患者的脉压差增大[(46.7±9.3)mmHg(1mmHg=0.133kPa)比(41.9±11.5)mmHg,P=0.007],心率[(84.2±14.7)次/min比(93.3±17.7)次/min,P〈0.001]和呼吸频率减慢(P〈0.001);超声心动图可见三尖瓣环收缩期位移显著升高[(18.7±3.1)mm比(15.9±3.9)mm,P〈0.001]、右心室横径显著缩小[(34.0±3.6)mm比(36.8±4.4)mm,P〈0.001];血气分析中氧分压[(87.9±17.8)mmHg比(73.4±20.1)mmHg,P〈0.001]、氧饱和度(96.6%±2.4%比92.5%±6.3%,P〈0.001)和肺泡动脉氧分压差[52.1(31.5,76.3)mmHg比29.9(12.3,55.1)mmHg,P=0.014]明显改善;D-二聚体明显升高(P〈0.001),N末端B型利钠肽原明显下降(P〈0.001)。溶栓过程无致死性大出血事件。肺栓塞相关病死率为6.9%(4/43),无一例新发CTEPH。结论阿替普酶100mg/2h溶栓方案可有效改善急性肺血栓栓塞症患者右心功能及预后。Objective To evaluate the efficacy and safety of 100 mg/2 hours recombinant tissuetype plasminogen activator (rt-PA) regimen for treating patients with acute pulmonary thromboembolism (PE) by observing long-term clinical outcome including recurrent pulmonary embolism, chronic thromboembolic pulmonary hypertension (CTEPH) and other complications. Methods Data of 43 consecutive patients with acute high-risk and intermediate-risk PE treated with intravenous rt-PA (100 mg/2 hours) were prospectively analyzed. Median follow-up post-thrombolysis was (15.6 + 11.4) months. The endpoints of the study were PE recurrence, death related to PE and onset CTEPH. Results After rt-PA therapy, pulse pressure increased [ (46.7 ±9. 5 ) mm Hg( 1 mm Hg = 0. 133 kPa) vs. (41.9 ±11.3 ) mm Hg, P = 0. 007 ], heart rate and ±2.4 ) bpm vs. (23.2 ±4. 1 ) bpm, P 〈 0. 001, respectively ] , tricuspid annular plane systolic excursion increased [ ( 18.7 ± 3.1 ) mm vs. ( 15.9 ± 3.9) ram, P 〈 0. 001 ] and right ventricle transverse diameter [ (34.0 ± 3.6) mm vs. (36. 8 ± 4.4) mm, P 〈 0. 001 ]. PO2, SO2 and P(n-a) O2 improved [ (87.9 ±17.8) mm Hg vs. (73.4±20. 1) mmHg, P〈0.001; 96.6% ±2.4% vs. 92.5% ±6.3%, P 〈 0.001; 29.9 (12.3, 55.1) mm Hg vs. 52.1 (31.5, 76.3) mm Hg, P = 0.014, respectively ] , D-dimer and NT-proBNP levels significant reduced ( P 〈 0. 001 ). Mortality rate related to PE was 6. 9% ( 4/43 ) and there was no patient developed CTEPH during follow up. Conclusion The 100 mg/2 hours rt-PA regimen is effective to treat acute PE patients and could improve right heart function and outcome in patients with acute PE.
