目的:研究心肌梗死患者择期行经皮冠状动脉介入(PCI)治疗对左心室重构和收缩功能的影响。方法:选取2009年12月到2014年12月我院收治的心肌梗死择期行PCI治疗的患者60例(研究组),另选同期单纯心绞痛行PCI治疗的患者60例(对照组)。比较治疗前、后两组左心室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、每搏量(SV)、左室射血分数(LVEF)、左室收缩末期压(LVESP)和左心室舒张末压(LVEDP)。结果:治疗后研究组LVEDV、LVESV、SV、LVEF、LVESP和LVEDP均显著优于治疗前,比较差异均具有统计学意义(P<0.05),对照组治疗前、后LVEDV、LVESV、SV、LVEF、LVESP和LVEDP比较差异均无统计学意义(P>0.05)。结论:心肌梗死患者行PCI治疗具有较好的效果,能显著改善患者的左心室重构和收缩功能。
Objective: To study the effects of percutaneous coronary intervention (PCI) on left ventricular remodeling and systolic function in patients with myocardial infarction. Methods: Sixty patients (study group) undergoing PCI during myocardial infarction scheduled for PCI in our hospital from December 2009 to December 2014 were enrolled in this study. Sixty patients (control group) undergoing PCI with simple angina pectoris during the same period were selected. The left ventricular end diastolic volume (LVEDV), end systolic volume (LVESV), stroke volume (SV), left ventricular ejection fraction (LVEF), left ventricular end-systolic pressure End-diastolic pressure (LVEDP). Results: The LVEDV, LVESV, SV, LVEF, LVESP and LVEDP in the study group were significantly better than those before treatment (P <0.05). The LVEDV, LVESV, SV, LVEF There was no significant difference between LVESP and LVEDP (P> 0.05). Conclusion: PCI in patients with myocardial infarction has a good effect, which can significantly improve the left ventricular remodeling and systolic function in patients.
