超声评价急诊PCI治疗STEMI患者左室舒张功能变化的临床研究
Study on Ultrasonography in Evaluation of Changes in Left Ventricular Diastolic Function after Emergent PCI in STEMI Patients
摘要
Abstract
Objective:To investigate the effect of emergent percutaneous coronary intervention ( PCI)on the left ventricular diastolic function in patients with ST elevation myocardial infarction ( STEMI) , to ana-lyze the ratio of the blood flow velocity in the early diastolic period in the mitral orifice to the velocity of move-ment of tissue doppler imaging ( E/E') , and to evaluate the values of left ventricular diastolic function in STE-MI patients. Methods:The echocardiogram data before, just after surgery, at 2 weeks after, and at 2 months after emergent PCI, and the left ventricular end-diastolic pressure (LVEDP) before and just after the emer-gent PCI in 30 STEMI patients were collected. Results: STEMI patients had significantly increased left ven-tricular ejection fraction ( LVEF) and significantly decreased E on the lateral wall just after, after 2 weeks, and after 2 months, the emergent PCI when compared with that before the surgery ( all P < 0.05); they had significantly decreased E just after PCI when compared with that before PCI ( P <0.05);and they had signifi-cantly increased left atrial volume index ( LAVI) at 2 weeks and 2 months after PCI when compared with that just after and before PCI ( P < 0.05) . The E/E' of the non- infarction zone in the mitral ring in the STEMI patients was insignificantly dependent on LVEDP determined before and just after the emergent PCI ( both P>0.05) . Conclusion:The STEMI patients have decreased left ventricular diastolic function at 2 weeks after e-mergent PCI, and significantly increased LAVI at 2 weeks and 2 months after the surgery. The relationship be-tween E/E' and LVEDP is not clear yet.关键词
