摘要
目的探讨血浆C-反应蛋白(CRP)水平对评估急性肺栓塞患者预后的价值。方法56例急性肺栓塞患者,通过螺旋CT、肺动脉造影(CTPA)、磁共振显像(MRI)、肺动脉造影确诊,入院后均行CRP、心电图(ECG)、超声心动图(UCG)、动脉血气分析等检查。结果CRP≥10mg/L共24例,其中大面积肺栓塞12例(50.O%),次大面积11例(45.8%),小面积栓塞1例(4.2%),死亡6例(25.0%);UCG示右心室功能不全24例(100.0%),肺动脉高压24例(100.0%),心电图示右心室负荷过重20例(83.3%),PaO2〈60mmHg22例(91.7%);晕厥8例(33.3%),心源性休克9例(37.5%)。CRP〈10mg/L者32例,其中大面积肺栓塞3例(9.4%),次大面积6例(18.8%),小面积23例(71.8%),死亡1例(6.3%);UCG示右心室功能不全13例(40.6%),肺动脉高压16例(50.0%),心电图示右心室负荷过重15例(46.9%),PaO2〈60mmHg 11例(34.4%);晕厥2例(6.3%),心源性体克4例(12.5%)。2组比较,大面积栓塞发生率、病死率、次大面积栓塞发生率差异均有统计学意义(P〈0.01或P〈0.05),辅助检查右心室功能不全、肺动脉高压、右心室负荷过重、PaO2〈60m/nHg发生率差异均有统计学意义(P均〈0.01),症状和体征中晕厥、心源性休克发生率差异均有统计学意义(P均〈0.05)。结论CRP可作为急性肺栓塞患者的预后指标,可以帮助明确危险分层。指导治疗。
Objective To assess the value of C-reactive protein(CRP) for the prognosis of acute pulmonary embolism (PE). Methods 56 acute pulmonary embolism patients, confirmed by spiral computed tomography( sCT), magnetic resonance imaging(MRI) ,or pulmonary angiography(CTPA). CRP as well as electrocardiogram (ECG), echocardiography(UCG) , blood gas analysis, were taken after admission. Results Among these patients, 24 cases with higher CRP( ≥ 10 mg/L) , were diagnosed as massive ( 50.0% ) , sub-massive PE ( 45.8% ), mini-massive (4.2%) or died(25.0% ). 24 cases (100.0%) showed right heart dysfunction and 24 cases showed pulmonary hypertension on UCG, right ventricular 20 ( 83. 8% ) on ECG, 22 cases ( 91.7% ) showed hypoxemia. 8 cases (33.3%) had syncope,and 9 cases (37.5%) had cardiogenic shock. CRP was lower than 10 mg/L in 32 patients, among whom,3 eases (9.4%) were with massive PE ,6 cases (18.8%) were with sub-massive PE ,23 (71.8%) were with small PE,1 cases(6.3% ) died. 13 (40.6%) had right heart dysfunction and 16(50.6% ) had pulmona- ry hypertension on UCG,right ventricular on ECG in 15 eases (46.9%) ,hypoxemia in 11 cases (34.4%) ,syncope in 2 cases (6.3%), cardiogenie shock in 4 cases ( 12.5 % ). The occurrence of massive PE, mortality ( P 〈 0.01 ) and sub-massive PE (P 〈 0.05 )were statistically different between the groups with higher CRP and the groups with lower CRP. The ratio of right heart dysfunction, pulmonary hypertension, right ventricular overloading, hypoxemia had statistical significance (P 〈 0. O1 ). There was statistical significance in the occurrence of syncope, eardiogenic shock ( P 〈 0.05 ). Conclusions CRP can be used as a parameter for PE, and can be used to stratify risk levels for severity and assess the effectiveness of treatment.
