摘要
目的探讨回顾性心电门控肺动脉CT血管造影技术(CTPA)在评估肺动脉高压(PH)患者肺动脉弹性功能和心功能的应用价值。方法收集2016年3月至2020年1月河北北方学院附属第一医院经临床表现和超声心动图诊断为PH且同时行回顾性心电门控CTPA的患者为PH组(30例),同时收集行回顾性心电门控CTPA且无肺动脉相关疾病、超声心动图肺动脉压力正常者为对照组(30例),比较两组动脉扩张度(AD)及心功能参数。结果PH组AD值低于对照组,差异有统计学意义(P<0.05)。PH组右室收缩末期容积、右室舒张末期容积、右室舒张末期容积/左室舒张末期容积、右室收缩末期容积/左室收缩末期容积高于对照组,右室射血分数低于对照组,差异有统计学意义(P<0.05)。结论回顾性心电门控CTPA能够无创评估PH患者肺动脉弹性功能及右心功能情况,为PH患者的诊治提供有力的影像学依据。
Objective To investigate the application value of retrospective ECG-gated CT pulmonary angiography(CTPA)in pulmonary artery elasticity and cardiac function in pulmonary hypertension(PH)patients.Methods From March2016 to January 2020,patients with PH diagnosed by clinical manifestations and echocardiography in the First Affiliated Hospital of Hebei North University and who received retrospective ECG-gated CTPA were included in PH group(30 cases).At the same time,the patients without pulmonary artery disease by retrospective ECG-gated CTPA and normal pulmonary artery pressure by echocardiography were collected as control group(30 cases).Arterial dilation(AD)and cardiac function parameters were compared between two groups.Results AD value of PH group was lower than that of control group,and the difference was statistical significant(P<0.05).The right ventricular end systolic volume,right ventricular end diastolic volume,right ventricular end diastolic volume/left ventricular end diastolic volume,and right ventricular end systolic volume/left ventricular end systolic volume of PH group were higher than those of control group,right ventricular ejection fraction was lower than that of control group,and the differences were statistical significant(P<0.05).Conclusion Retrospective ECG-gated CTPA can noninvasively assess pulmonary artery elasticity and right cardiac function in PH patients,so as to provide a forceful imaging basis for the diagnosis and treatment of PH patients.
