【摘要】目的

研究入院时收缩压(systolic blood pressure,SBP)水平对急性ST段抬高心肌梗死(STEMI)在院期间预后的影响。

访法 回顾性分析中国医科大学附属盛京医院2008年9月至2011年6月收治入院的335例STEMI患者,根据入院时SBP水平将335例STEMI患者分为4组,分别是:<101 mmHg(1 mmHg=0.133 kPa )(n=59),101~120 mmHg(n=109),121~140 mmHg(n=98),>140 mmHg(n=69)。比较各组的基本临床资料、冠状动脉造影发现(coronary angiography,CAG)、治疗方法、院内并发症和院内病死率。

结果 各组STEMI患者院内病死率分别是18.64%、1.83%、4.08%、1.45%,入院SBP<101 mmHg组病死率、killip≥3级、休克、严重心律失常发生率及经安装起搏器、IABP治疗率均高于其他3组。SBP≥101 mmHg的3组病死率没有明显差别。经多因素Logistic回归分析显示SBP<101 mmHg(OR=6.368,P=0.002)、肌钙蛋白I峰值(OR=3.781,P=0.008)是入院STEMI患者死亡的独立危险因素。

结论 入院SBP<101 mmHg患者在院期间病死率高,入院收缩压低可作为判断STEMI患者预后不良的一个较好指标。

【Abstract】Objective To investigate the impact of systolic blood pressure(SBP) at admissionon in-hospital outcomes in patients with ST elevated acute myocardial infarction(STEMI).Methods Data of 336 STEMI patients admitted from September 2008 to May 2011 were retrospectively analyzed. Total of 336 STEMI patients were classified into 4 groups as per the level of SBP at admission: group A (<101 mmHg, n=59); group B (101-120 mmHg, n=109); group C (121-140 mmHg, n=98) and group D (>140 mmHg, n=69). And clinical features, coronary angiography (CAG) findings, the strategy of treatment, complications and hospital mortality were compared among 4 groups with SPSS version 18.0 software. Results The mortality rates of the four groups were 18.64%,1.83%,4.08%,1.45%, respectively. The patients with SBP<106 mmHg were in greater risk of in-hospital mortality, Killip class≥3 at admission, shock and refractory arrhythmias, and more patients in this group needed pacemaker and intra-aortic balloon pump (IABP) treatment than patients in other 3 groups. While there was no significant difference in mortality rate between other three groups. Multivariate logistic regression analysis demonstrated SBP<101 mmHg (OR=6.368, P=0.002) and peak value of troponin I (OR=3.781, P=0.008) were independent risk factors of in-hospital death in STEMI patients. Conclusions The STEMI patients with SBP<101 mmHg at admission had higher mortality rate and low SBP at admission had great prognostic value in short-term outcomes of STEMI.

急性心肌梗死(AMI)并发心源性休克在临床上具有很高的病死率,已有非常多的研究证实AMI患者入院时的收缩压(SBP)与在院期间病死率有密切的关系。入院时的SBP被认为是对AMI患者进行早期危险分层的有效因素,并且国外专家建议的众多风险评分方法中都包括入院时的SBP[1-2],而在AMI患者中ST段抬高性心肌梗死(STEMI)较非ST段抬高心肌梗死(NSTEMI)的梗死程度更为严重。本文研究入院时SBP对STEMI患者在院期间预后的影响。

1 资料与方法

1.1 一般资料 选择2008年9月至2011年6月在中国医科大学附属盛京医院心内科接受治疗的STEMI患者335例,其中男249例,女86例,所有病例均符合中华医学会心血管病学分会2010年制定的STEMI诊断标准[3]。入院后均反复查心肌酶谱、心肌型肌酸激酶同工酶(CKMB),行肌钙蛋白I以及心电图监测,全部病例都有肌钙蛋白的特异性增高,心肌酶谱及心电图的动态变化。……
