急性心肌梗死患者延迟PCI心功能的变化及临床意义

目的:通过测定急性心肌梗死(AMI)延迟冠脉介入治疗(PCI)患者EF值变化来评价延迟PCI对左室重构的影响,为延迟PCI的疗效提供理论依据和客观指标.方法:AMI后行延迟PCI的患者34人为治疗组,未行PCI和溶栓的患者38人为对照组,分别在AMI后2周和恢复期做超声心动图测EF值,并进行统计学处理.结果:两组比较,治疗组在恢复期EF值有显著升高.结论:AMI后由于左室重构导致EF值降低,延迟PCI能阻止和改善左室重构.

FLUCTUATION OF THE PLASMA BNP CONCENTRATION IN PATIENTS WITH AMI AFTER DELAYED PCI AND ITS CLINIC SIGNIFICANCE

Objective: To investigate the relation between delayed PCI with AMI and the improvement of left ventricular remodeling depended on changes Echocardiography EF value before and after delayed PCI. This provided an objective standard and theory basis for the delayed PCI in left ventricular remodeling interference. Methods: 72 patients with AMI were divided into delayed PCI group( treatment group, n=34 ) and medical treatment group(control group, n=38). Echocardiography EF value was measured 2 weeks after AMI and the recovery stage. Datum was statistically analyzed. Results: Compare the two groups, The echocardiography EF value were significantly increased for the treated group on the recovery stage. Conclusions: There is left ventricular remodeling taking place after AMI, lead to lower EF value. delayed PCI can help to prevent left ventricular remodeling and improve heart function. It is a good index to value the curative effect of delayed PCI in improving heart function.
