摘要
目的应用超声心动图量化评价经皮冠状动脉介入(PCI)术前后非ST段抬高急性冠脉综合征(NSTEACS)患者左心室结构与心功能变化。方法选择经冠状动脉造影(CAG)证实存在冠状动脉狭窄或闭塞并接受PCI术的NSTEACS患者20例,比较术后与术前超声心动图反映左心室结构与收缩功能指标的变化:室间隔(IVS)与左室后壁(LVPW)厚度,左心室舒张末期内径(LVDd)和收缩末期内径(LVDs),左室射血分值(LVEF)和左室短轴缩短率(FS),左室舒张末期容量(LVVd)和收缩末期容量(LVVs)等。结果LVEF、FS术后与术前相比具有统计学意义(P<.01),其余各指标术后与术前相比差异均无统计学意义。结论20例患者PCI术后左室收缩功能显著提高;左心室结构无明显改变。
Objective To quantitatively evaluate the changes of left ventricular structure and function in non-ST-segment elevated acute coronary syndromes （NSTEACS） before and after percutaneous coronary intervention （PCI） by echocardiography（ECHO）. Methods 20 hospitalized patients were recruited who were clinically diagnosed as NSTEACS with significant coronary artery stenosis or infarction after undergoing coronary artery angiography （CAG） and were successfully performed PCI. The differences of some parameters on echocardiography were compared such as left ventricular structure and systolic function between before and after PCI. Results There were significant increasing in LVEF and FS after PCI than before PCI; No significant differences were found in other parameters between after PCI and before PCI. Conclusions There is significant improvement on left ventricular systolic function after PCI; No significant differences are found in parameters of left ventricular structure on echocardiography between after PCI and before PCI.
