目的探讨急性心肌梗死(AMI)患者直接经皮冠状动脉介入术(PCI)治疗后心率与预后的关系。方法 2008年1月至2009年7月住院的ST段抬高AMI患者417例,根据术后第1份心电图心率水平,分为≤80次/min组及>80次/min组,比较两组患者心肌酶水平及住院期间并发症情况。结果 PCI术后心率≤80次/min组患者心肌酶峰值、发生心源性休克、室颤室速、心力衰竭,以及应用主动脉内球囊反搏(IABP)比例显著低于心率>80次/min组患者,且护理过程中自觉全身不适、心悸、呼吸困难等症状显著减轻,而左室射血分数、自觉胸痛症状缓解明显。结论 PCI术后心率>80次/min患者预后差,应在护理过程中重视患者心率的变化,配合临床治疗,改善预后。
Objective To investigate the relationship between heart rate and prognosis after direct percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods 417 ST-segment elevation AMI patients admitted to hospital from January 2008 to July 2009 were divided into two groups according to the first electrocardiogram heart rate (HRT) ≤80 beats / min and> 80 beats / min. Patients with myocardial enzyme levels and complications during hospitalization. Results The peak of myocardial enzymes, cardiogenic shock, ventricular tachycardia, heart failure and intra-aortic balloon pumping (IABP) in patients with heart rate ≤ 80 beats / min after PCI were significantly lower than those with heart rate> 80 / min patients, and the process of nursing consciously unwell, palpitations, dyspnea and other symptoms significantly reduced, and left ventricular ejection fraction, conscious chest pain relief significantly. Conclusions Patients with a heart rate> 80 beats per minute after PCI have a poor prognosis. Patients should be given great attention to the change of heart rate during the course of nursing. With the clinical treatment, the prognosis should be improved.
