Application value of echocardiography in the evaluation of cardiac morphology and function in patients with acute cerebral infarction

目的研究超声心动图在急性脑梗死患者心脏形态结构及功能评估中的应用价值。方法选择2018年3月—2020年3月安徽省蚌埠市第一人民医院(以下简称“我院”)收治的80例急性脑梗死患者为急性脑梗死组,同期选择在我院门诊体检的健康人群64例为对照组。比较两组左心形态结构、右心形态结构和心功能。结果急性脑梗死组患者左室收缩末期容积、左室舒张末容积、左室后壁舒张期厚度、左室舒张末期内径及左房内径大于对照组,差异均有统计学意义(均P<0.05)。急性脑梗死组患者右室舒张期室间隔厚度、右室舒张末期内径及主肺动脉内径大于对照组,差异均有统计学意义(均P<0.05)。急性脑梗死组患者每搏量、左室射血分数、二尖瓣舒张早期最大血流速度及二尖瓣舒张早期最大血流速度/二尖瓣舒张晚期最大血流速度低于对照组,二尖瓣舒张晚期最大血流速度高于对照组,差异均有统计学意义(均P<0.05)。结论左心室肥厚及左房增大为急性脑梗死患者较常见的超声心动图心脏结构变化,通过超声心动图观察心脏形态结构及功能可为急性脑梗死诊治提供参考依据。

Objective To study the application value of echocardiography in the evaluation of cardiac morphology and function in patients with acute cerebral infarction.Methods A total of 80 patients with acute cerebral infarction admitted to Bengbu First People’s Hospital of Anhui Province(“our hospital”for short)from March 2018 to March 2020 were selected as the acute cerebral infarction group,while 64 healthy people who had physical examination in Department of Outpatient of our hospital were selected as the control group.The left heart morphology,right heart morphology and cardiac function were compared between the two groups.Results The left ventricular end-systolic volume,left ventricular end-diastolic volume,left ventricular posterior wall diastolic thickness,left ventricular end-diastolic inner diameter and left atrial inner diameter in patients with the acute cerebral infarction group were larger than those in the control group,and the differences were statistically significant(all P<0.05).The right ventricular diastolic interventricular septum thickness,right ventricular end diastolic inner diameter and main pulmonary artery inner diameter in patients with the acute cerebral infarction group were larger than those in the control group(all P<0.05).Stroke volume,left ventricular ejection fraction,early diastolic mitral valve maximum blood flow velocity and early diastolic mitral valve maximum blood flow velocity/late diastolic mitral valve maximum blood flow velocity in patients with the acute cerebral infarction group were lower than those of the control group,and late diastolic mitral valve maximum blood flow velocity was higher than that in the control group,and the differences were statistically significant(all P<0.05).Conclusion Left ventricular hypertrophy and left atrial enlargement are common echocardiographic changes in cardiac morphology in patients with acute cerebral infarction.Observing cardiac morphology and function of the heart by echocardiography can provide a reference for the diagnosis and treatment of acute cerebral infarction.
