【摘要】：目的观察经皮冠状动脉介入术(PCI)治疗不稳定型心绞痛(UA)患者的左心室收缩功能及同步性变化。方法左前降支梗阻的UA患者35例(观察组),采用PCI治疗;另选同期健康体检者25例作为对照(对照组)。两组均进行实时三维超声心动图检查,比较两组左心室整体功能参数、节段功能参数及同步性参数。结果与对照组比较,观察组术前整体收缩末期容积(g ESV)、R-R间期校正的左心室16节段达到最小容积时间的标准差(Tmsv16-SD%)增加,整体射血分数(g EF)、峰值射血率(PER)/左心室整体舒张末期容积(g EDV)减小;与术前比较,观察组术后g ESV、Tmsv16-SD%减小,g EF、PER/g EDV增加。与对照组比较,观察组术前前壁心尖段节段舒张末期容积(r EDV)增加;与对照组比较,观察组术后前壁心尖段r EDV减小。与对照组比较,观察组术前左前降支供血节段(除前间隔基底段外)的节段收缩末期容积(r ESV)增加;与术前比较,观察组术后左前降支供血节段(除前间隔基底段外)r ESV减小。与对照组比较,观察组术前左前降支供血节段(除前间隔基底段外)节段射血分数(r EF)减小;与术前比较,观察组术后左前降支供血节段(除前间隔基底段外)r EF增加。P均0.05。结论 UA患者PCI术前左心室收缩功能及同步性均降低,术后左心室整体收缩功能及节段收缩功能增强,左心室收缩同步性得到改善。
[Abstract]:Objective to observe the changes of left ventricular systolic function and synchronism in patients with unstable angina pectoris (UAA) treated by percutaneous coronary intervention (PCI). The patients were treated with PCI. In addition, 25 healthy persons were selected as control group (control group). The two groups were examined by real-time three-dimensional echocardiography, and the global left ventricular function parameters were compared between the two groups. Results compared with the control group, the whole end-systolic volume (ESVG) of the observation group was compared with that of the control group. R-R interval corrected left ventricular 16-segment standard deviation to minimum volumetric time (TMS v16-SD) was increased and global ejection fraction (EFG) was increased. The peak ejection rate (peg EDV) and the global end-diastolic volume (EDV) of left ventricle decreased. Compared with pre-operation, g ESVV Tsv16-SD% decreased the increase of g EFP P P r / g EDV in the observation group and compared with that in the control group. In the observation group, the end diastolic volume of the apical segment of the anterior wall was increased before operation. Compared with the control group, the r EDV of the apical segment of the anterior wall in the observation group was decreased after operation, and compared with that in the control group. In the observation group, the end systolic volume of the left anterior descending branch (except the basal segment of the anterior septum) was increased before operation. Compared with pre-operation, the left anterior descending branch (r ESV) was decreased in the observation group (except the basal segment of the anterior septum) and compared with that in the control group. In the observation group, the ejection fraction of the left anterior descending branch (except the basal segment of the anterior septum) was decreased before operation. Compared with pre-operation, the left anterior descending branch in the observation group (except the basal segment of anterior septum) increased in EF (P 0.05). Conclusion the left ventricular systolic function and synchrony of UA patients before PCI were decreased. Global left ventricular systolic function and segmental systolic function were enhanced, and left ventricular systolic synchronism was improved.
