摘要:
目的 评价多普勒组织成像（DTI）法测量脉搏波速的真实性和可行性。方法 行冠脉造影患者50例,测量主动脉两定点距离L,并与体表不同标志做相关性分析。测量脉搏波传递时间(PWT1),脉搏波速（PWV1）=L/PWT1,此40例患者行DTI法测量电-机械时间(EMT)、左室射血前期(PEP)、脉搏波传递时间(PWT2),PWT2=EMT-PEP,PWV2=L/PWT2,两种方法测得PWT1与PWT2,PWV1与PWV2分别行直线相关分析;上述主动脉两定点距离与体表长度间行相关性分析。结果 PWT1为(24±9)ms,PWT2为(24±9)ms,二者之间无显著差异,具有显著相关性(r=0.91,P<0.01)。PWV1为(14±5)m/s,PWV2为(14±5)m/s,二者之间无明显差异,亦具有高度相关性(r=0.92,P<0.01)，上述主动脉两定点距离与胸骨角至胸骨体下缘长度2倍加1 cm的相关系数为0.90,而且这两组数据间无显著性差异。结论 DTI法可做为无创测量PWT方法，选用胸骨角至胸骨体下缘长度2倍加1 cm做为主动脉段长度估计值测得的PWV值是准确可用的。
Abstract:
AIM: To study the correlation of two measured values of pulse wave time: PWT1 obtained by catheter and PWT2 obtained by Doppler tissue image (DTI) and the correlation of two measured values: aortic root to a point in the abdominal aorta 2 cm below the septum and length of body surface and to estimate the validity and feasibility of pulse wave velocity measurement using DTI . METHODS: A total 50 patients who had coronary arteriography were included in this study. Length of artery (L) was measured to study the correlation between L and different surface markers. PWV1 was obtained by PWV1=L/PWT1. Electromechanical time (EMT) and left ventricular pre-ejection period (PEP) were measured by DTI, and PWV2 was obtained by PWT2 = EMT-PEP, PWV2=L/PWT2. PWT1 and PWT2, PWV1 and PWV2, and the value of distance from aortic root to a point in the abdominal aorta 2 cm below the septum and the value of length of surface were then statistically compared. RESULTS: PWT1 was (24±9)ms and PWT2 was (24±9)ms, with no significant difference between PWT1 and PWT2. A positive correlation was found between the two (r=0.91, P<0.01). PWV1 was (14±5)m/s and PWV2 was (14±5)m/s, with no significant difference between PWV1 and PWV2, but a positive correlation was also found between the two (r=0.92, P<0.01). A positive correlation was found between the value of length of artery and the 1 cm+double values of length from angle of sternum to inferior border of sternum (r=0.90, P<0.01). CONCLUSION: DTI is a noninvasive approach to measure PWT and PWV. PWV from the estimated value of the length of artery is precise by using 1 cm+double values of length from angle of sternum to inferior border of body of sternum.
