目的 采用速度向量成像(VVI)技术评价缺血性心肌室壁运动异常程度.方法 选取因心前区疼痛接受冠状动脉造影患者,按检查结果分为心肌缺血组31例、心肌梗死组25例及对照组30例,所有患者均在规定时间内进行超声心动图检查.采用VVI技术分析心底部及心尖部各节段(前壁、前间隔、后壁、侧壁、下壁及后间隔)的收缩期旋转角度及速度、舒张期旋转速度.结果 心肌梗死组左室的旋转运动存在多节段上不同一性,幅度及形式上也与对照组存在不同,心肌梗死组与对照组心尖部、心底部各节段旋转角度比较差异有统计学意义(P＜ 0.01或＜0.05).心肌缺血组与对照组心尖部、心底部各节段旋转角度比较差异无统计学意义(P＞0.05).在心底部水平:心肌梗死组前壁、前间隔及后间隔收缩期旋转速度显著低于对照组(P＜0.05),前壁、后壁、侧壁、前间隔及后间隔舒张期旋转速度显著低于对照组(P＜ 0.05或＜0.01),两组收缩期旋转角度比较差异无统计学意义(P＞0.05).心肌缺血组前间隔及后间隔舒张期旋转速度显著低于对照组(P＜0.05),余各节段收缩期旋转速度、舒张期旋转速度、收缩期旋转角度与对照组比较差异均无统计学意义(P＞0.05).在心尖部水平:心肌梗死组前壁、后壁、侧壁及前间隔收缩期旋转速度显著低于对照组(P＜0.01或＜0.05),前壁、后壁、下壁、侧壁及前间隔舒张期旋转速度显著低于对照组(P＜0.01或＜0.05).心肌缺血组前壁及下壁舒张期旋转速度低于对照组,差异有统计学意义(P＜0.05),余各节段收缩期旋转角度及速度、舒张期旋转速度与对照组比较差异均无统计学意义(P＞0.05).结论 应用VVI技术定量分析心肌扭转运动可能有助于早期检出和鉴别心肌缺血及心肌梗死.
目的 採用速度嚮量成像(VVI)技術評價缺血性心肌室壁運動異常程度.方法 選取因心前區疼痛接受冠狀動脈造影患者,按檢查結果分為心肌缺血組31例、心肌梗死組25例及對照組30例,所有患者均在規定時間內進行超聲心動圖檢查.採用VVI技術分析心底部及心尖部各節段(前壁、前間隔、後壁、側壁、下壁及後間隔)的收縮期鏇轉角度及速度、舒張期鏇轉速度.結果 心肌梗死組左室的鏇轉運動存在多節段上不同一性,幅度及形式上也與對照組存在不同,心肌梗死組與對照組心尖部、心底部各節段鏇轉角度比較差異有統計學意義(P＜ 0.01或＜0.05).心肌缺血組與對照組心尖部、心底部各節段鏇轉角度比較差異無統計學意義(P＞0.05).在心底部水平:心肌梗死組前壁、前間隔及後間隔收縮期鏇轉速度顯著低于對照組(P＜0.05),前壁、後壁、側壁、前間隔及後間隔舒張期鏇轉速度顯著低于對照組(P＜ 0.05或＜0.01),兩組收縮期鏇轉角度比較差異無統計學意義(P＞0.05).心肌缺血組前間隔及後間隔舒張期鏇轉速度顯著低于對照組(P＜0.05),餘各節段收縮期鏇轉速度、舒張期鏇轉速度、收縮期鏇轉角度與對照組比較差異均無統計學意義(P＞0.05).在心尖部水平:心肌梗死組前壁、後壁、側壁及前間隔收縮期鏇轉速度顯著低于對照組(P＜0.01或＜0.05),前壁、後壁、下壁、側壁及前間隔舒張期鏇轉速度顯著低于對照組(P＜0.01或＜0.05).心肌缺血組前壁及下壁舒張期鏇轉速度低于對照組,差異有統計學意義(P＜0.05),餘各節段收縮期鏇轉角度及速度、舒張期鏇轉速度與對照組比較差異均無統計學意義(P＞0.05).結論 應用VVI技術定量分析心肌扭轉運動可能有助于早期檢齣和鑒彆心肌缺血及心肌梗死.

Objective To assess segmental ventricular wall motion abnormalities in patients with coronary artery heart disease by velocity vector imaging (VVI).Methods Eight-six patients of chest pain having underwent coronary angiography were selected,and were divided into myocardial ischemia group (31 cases),myocardial infarction group(25 cases) and normal group (30 cases) according to test results.All the patients were checked with ultrasonic cardiogram in specified time.Systolic rotation angle and speed,diastolic rotation speed in the bottom and apex heart of each segment (anterior,anterior septum,posterior,lateral,inferior wall,interval) was analyzed by VVI.Results Rotary motion of the left ventricle was not consistent in different segment in myocardial infarction group,and the extent and form was different compared with that in normal group.Compared with that in normal group,bottom and apex heart angle of rotation of each segment in myocardial infarction group showed significant difference (P ＜ 0.01 or ＜ 0.05).The rotation angle of each segment in apex and bottom heart between myocardial ischemia group and normal group had no statistical significance (P ＞0.05).In bottom heart:the systolic rotation speed on anterior wall,anterior septum,posterior wall and lateral wall in myocardial infarction group was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05),and the diastolic rotation speed on anterior wall,anterior septum,posterior wall,lateral wall,inferior wall was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05).The systolic rotation angle between two groups was not statistically significant (P ＞ 0.05).The diastoic rotation speed on anterior interval septum in myocardial ischemia group was statistically lower than that in normal group (P ＜ 0.05),the systolic rotation angle and speed,diastolic rotation speed in other segment was not statistically significant compared with that in normal group (P ＞ 0.05).In apex heart,the systolic rotation speed in anterior wall,anterior septum,posterior wall in myocardial infarction group was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05),and the diastolic rotation speed in anterior wall,posterior wall,lateral wall,inferior wall was statistically lower than that in normal group (P ＜ 0.01 or ＜ 0.05).The diastolic rotation speed on anterior and inferior wall in myocardial ischemia group was statistically lower than that in normal group (P ＜ 0.05),and the systolic rotation angle and speed,diastolic rotation speed in other segment was not statistically significant (P ＞ 0.05) compared with that in normal group.Conclusion VVI technique in ultrasonic cardiogram can check out difference between myocardial ischemia and myocardial infarction incipiently.
