急性心肌梗死初发高血糖的临床研究

目的:探讨急性心肌梗死(AMI)初发高血糖的临床研究即既往无糖尿病病史的AMI患者发病早期血糖变化规律,及高血糖与口服葡萄糖耐量试验(OGTT)的关系,以明确反应性高血糖变化规律并及早发现合并糖尿病和糖调节受损的患者以指导治疗。方法:从2009-02到2009-09,连续入选既往无糖尿病病史,且在发病48 h内接受急诊经皮冠状动脉治疗的ST段抬高型AMI患者,在入院即刻和入院后第2～7天连续6天清晨6点采集患者空腹血液,化验血糖浓度,在出院前进行OGTT,共纳入有效病例158例,按照1999年世界卫生组织OGTT分类标准分为糖代谢正常者、糖调节受损者和新诊断糖尿病者;非糖尿病患者包括糖代谢正常者和糖调节受损者,评价血糖水平在心肌梗死急性期的变化规律。以入院第2天空腹血糖≥7.0 mmol/L为高血糖,评价高血糖与OGTT阳性的关系。结果:158例患者中糖代谢正常者占27.8%(44/158)、糖调节受损者占41.1%(65/158)、新诊断糖尿病者占31.0%(49/158)。所有患者平均血糖在入院后第4天降至正常水平,糖代谢正常者平均血糖在入院后第2天降至正常水平,非糖尿病患者平均血糖在第3天降至正常水平。空腹高血糖与OGTT阳性一致性检验Kappa=0.338,P=0.000,在校正其他变量的情况下,第2天空腹血糖≥7.0 mmol/L都是糖尿病(OGTT阳性)的预测因素(风险比=4.75,95%可信区间2.304～9.79,P=0.000)。结论:既往无糖尿病病史的AMI患者绝大多数合并糖代谢异常,需要进一步通过OGTT及时发现合并糖尿病或糖调节受损的患者以指导临床治疗;AMI患者反应性高血糖一般持续2～3天,如果存在持续高血糖提示患有糖尿病或糖调节受损的可能性大。高血糖是患有糖尿病的一个预测因素。     

Persistent hyperglycemia is associated with left ventricular dysfunction in patients with acute myocardial infarction.

BACKGROUND: The relationship of changes in blood glucose concentrations after admission to left ventricular (LV) dysfunction in patients with recanalized anterior acute myocardial infarction (AMI) remains unclear. METHODS AND RESULTS: Blood glucose concentrations were measured on admission and 24 h after symptom onset in 210 patients with recanalized anterior AMI within 6 h of symptom onset. Of them, 142 had hyperglycemia on admission, defined as a blood glucose >or=8.9 mmol/L, and 68 patients did not. Among the patients with admission hyperglycemia, 49 had persistent hyperglycemia, defined as a blood glucose >or=8.9 mmol/L 24 h after onset, and 93 did not. The incidences of myocardial blush grade of 0/1 after recanalization indicating impaired myocardial perfusion (71%), and peak creatine kinase concentration (5,631+/-2,855 mU/ml) were higher and predischarge LV function (43+/-11%) was lower in patients with persistent hyperglycemia than in those without (p<0.01). Multivariate analysis showed that persistent hyperglycemia was independently associated with LV dysfunction, defined as a predischarge LV ejection fraction 相似文献   

Admission blood glucose level as risk indicator of death after myocardial infarction in patients with and without diabetes mellitus

BACKGROUND: High admission blood glucose levels after acute myocardial infarction (AMI) are common and associated with an increased risk of death in subjects with and without known diabetes. Recent data indicate a high prevalence of abnormal glucose metabolism in patients with unknown diabetes at the time of AMI. We investigated the predictive value of admission blood glucose levels after AMI for long-term prognosis in patients with and without previously diagnosed diabetes mellitus, particularly in those with unknown diabetes but with blood glucose levels in the diabetic range. METHODS: In a retrospective study with prospective follow-up, 846 patients (737 without and 109 with known diabetes) were eligible for follow-up during a median of 50 months (range, 0-93 months). RESULTS: During follow-up, 208 nondiabetic patients (28.2%) and 47 diabetic patients (43.1%) died (P =.002). An increase of 18 mg/dL (1 mmol/L) in glucose level was associated with a 4% increase of mortality risk in nondiabetic patients and 5% in diabetic patients (both P<.05). Of the 737 previously nondiabetic subjects, 101 had admission blood glucose levels of 200 mg/dL (11.1 mmol/L) or more, and mortality in these patients was comparable to that in patients who had established diabetes (42.6% vs 43.1%). CONCLUSIONS: Admission blood glucose level after AMI is an independent predictor of long-term mortality in patients with and without known diabetes. Subjects with unknown diabetes and admission glucose levels of 200 mg/dL (11.1 mmol/L) or more after AMI have mortality rates comparable to those of subjects with established diabetes. Admission blood glucose level may serve to identify subjects at high long-term mortality risk, in particular among those with unknown diabetes.     

入院血糖水平对糖尿病和非糖尿病ST段抬高急性心肌梗死患者预后的影响

目的 探讨人院时血糖水平与糖尿病和非糖尿病患者ST段抬高急性心肌梗死(STEMI)患者近期病死率的相关性.方法 观察性分析国际性随机对照临床试验中7446例出现症状12 h内STEMI的中国患者,以入院血糖不同水平将已知糖尿病和非糖尿病的患者分组:入院血糖水平<6.1 mmol/L组(2018例),6.1～7.7 mmol/L组(2170例),7.8～11.0 mmol/L组(1929例),11.1～13.0 mmol/L组(465例)和>13.0 mmol/L组(864例),后3组定义为入院高血糖组.分析各组患者30 d的病死率.结果 在人院高血糖患者中有相当比例无既往的糖尿病史;各血糖水平组内,非糖尿病的患者使用胰岛素的比例均明显低于糖尿病患者.随血糖水平升高,非糖尿病患者病死率呈逐渐增加趋势(血糖<6.1 mmol/L组6.8%,6.1～7.7 mmol/L组8.3%,>13.0 mmol/L组18.6%,P<0.001),而糖尿病患者的病死率呈先降低后升高的变化(血糖<6.1 mmol/L组16.7%,6.1～7.7 mmol/L组8.2%,>13.0 mmol/L组22.0%,P<0.001);除显著高血糖(血糖>13.0mmol/L)外,非糖尿病的高血糖患者病死率高于相同血糖水平的糖尿病患者(均P<0.05).多变量logistic回归分析显示,在非糖尿病患者中,随血糖升高死亡危险逐步增加(血糖7.8～11.0 mmol/L组:OR=1.85,95%CI:1.45～2.34,P<0.001;血糖>13.0 mmoL/L组:OR=2.69,95%CI:1.97～3.66,P<0.001);而糖尿病患者中,除显著高血糖组外(血糖>13.0 mmol/L组:OR=3.08,95%CI:1.16～8.17,P=0.024),其他组近期死亡危险均无明显增加(均P>0.05).结论 与糖尿病患者相比,无既往糖尿病史的STEMI患者入院血糖水平升高也很常见,但接受治疗的比例较低,并且是与近期预后不良更密切相关的危险因素.

Is admission hyperglycaemia in non-diabetic patients with acute myocardial infarction a surrogate for previously undiagnosed abnormal glucose tolerance?

AIMS: To investigate whether admission hyperglycaemia in non-diabetic patients with acute myocardial infarction (AMI) is a surrogate for previously undiagnosed abnormal glucose tolerance. METHODS AND RESULTS: Two hundred non-diabetic patients with AMI were divided into three groups: 81 patients with admission glucose < 7.8 mmol/L (group 1), 83 patients with admission glucose > or = 7.8 mmol/L and < 11.1 mmol/L (group 2), and 36 patients with admission glucose > or = 11.1 mmol/L (group 3). Abnormal glucose tolerance, diabetes, or impaired glucose tolerance (IGT) was diagnosed by oral glucose tolerance test (OGTT). OGTT identified diabetes in 53 patients (27%) and IGT in 78 patients (39%). When the fasting glucose criteria were applied, however, only 14 patients (7%) were diagnosed as having diabetes. The prevalence of abnormal glucose tolerance was similar among the three groups: 67% in group 1, 63% in group 2, and 69% in group 3 (P = 0.74). The relation of fasting glucose (r2 = 0.50, P < 0.001) and HbA1c (r2 = 0.34, P < 0.001) to 2-h post-load glucose was significant, but the relation of admission glucose to 2-h post-load glucose was not significant (r2 = 0.02, P = 0.08). Multivariable analysis showed that fasting glucose and HbA1c were independent predictors of abnormal glucose tolerance, but admission glucose was not. CONCLUSION: Admission hyperglycaemia in non-diabetic patients with AMI does not represent previously undiagnosed abnormal glucose tolerance. Fasting glucose and HbA1c, rather than admission glucose, may be useful to predict abnormal glucose tolerance. However, these parameters lacked sensitivity. OGTT should be considered in all non-diabetic patients with AMI.

目的探讨急性心肌梗死（AMI）患者血糖水平与经皮冠状动脉介入（PCI）干预后住院期间心脏不良事件的相关性。方法入选312例初发AMI患者于入院即刻测定静脉血糖,并于发病24h内行急诊PCI。根据入院即刻血糖水平分为高血糖组（血糖〉11mmol／L,44例）和血糖正常组（血糖≤11mmol／L,268例）;按是否合并糖尿病分为糖尿病组（81例）和非糖尿病组（231例）。随访患者住院期间病死率及术后180d心脏不良事件发生率。结果无论是否合并糖尿病,高血糖组住院期间病死率及PCI术后180d心脏不良事件发生率均明显高于血糖正常组（18．2％比3．0％,P〈0．001;25％比12．7％,P=0．047）,多因素分析显示入院即刻血糖为死亡及心脏不良事件的独立预测因素（OR5．15,95％CI 1．74～15．28,P=0．003及OR 2．84,95％CI 1．18～6．83,P=0．019）,而是否合并糖尿病对上述终点无明显影响。结论无论是否合并糖尿病,入院即刻高血糖是AMI患者PCI术后住院期间病死率和180d心脏不良事件的相对独立危险因素。     

Effects of glucose abnormalities on in-hospital outcome after coronary intervention for acute myocardial infarction.

BACKGROUND: The effects of glucose abnormalities on outcomes after percutaneous coronary intervention (PCI) remain unclear. We examined the association between glucose abnormalities and in-hospital outcome in patients undergoing PCI for acute myocardial infarction (AMI). METHODS AND RESULTS: A total of 849 patients with AMI who were admitted within 12 h after symptom onset and underwent emergency PCI were classified according to the presence or absence of admission hyperglycemia, defined as a blood glucose level on admission of >11 mmol/L and whether they had a history of diabetes mellitus: group 1 (n = 504), non-diabetic patients without admission hyperglycemia; group 2 (n = 111), diabetic patients without admission hyperglycemia; group 3 (n = 87), non-diabetic patients with admission hyperglycemia; and group 4 (n = 147), diabetic patients with admission hyperglycemia. Among groups 1, 2, 3 and 4, in-hospital mortality was 2.6, 2.7, 11.5 and 8.8%, respectively (p < 0.01). Multivariate analysis showed that compared with group 1 patients, the odds ratio (95%confidence interval) for in-hospital mortality among those in groups 2, 3, and 4 were 0.80 (0.24-2.60, p = 0.708), 2.29 (1.10-5.49, p = 0.039), and 2.14 (1.14-4.69, p = 0.048), respectively. CONCLUSIONS: In-patients undergoing PCI for AMI, admission hyperglycemia, irrespective of the presence or absence of diabetes, is associated with increased in-hospital mortality, whereas diabetes without admission hyperglycemia is not.     

入院血钠水平与急性心肌梗死介入治疗患者预后的关系研究

目的:探讨入院血Na~+水平与急性心肌梗死(AMI)介入治疗预后的关系。方法:回顾性分析150例AMI患者的临床资料,按患者入院即刻、入院24、48 h血Na~+水平最低值将其分为正常组45例(血Na~+135 mmol/L)、轻度低钠组75例(轻度组,血Na~+120~135 mmol/L)、重度低钠组30例(重度组,血Na~+120 mmol/L),所有患者均完成介入治疗,比较各组肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)、肌钙蛋白(cTnI)水平、左室射血分数(LVEF)、心肌梗死面积等指标的差异,统计住院30d患者病死率。结果:3组空腹血糖、血脂水平比较差异无统计学意义(均P0.05)。轻度组CK-MB、cTnI水平高于正常组(均P0.05),重度组CK、CK-MB、cTnI水平均高于轻度组与正常组(P0.05)。正常组LVEF高于轻度组、重度组,且轻度组高于重度组(均P0.05)。重度组心肌梗死面积大于轻度组与正常组,且轻度组大于正常组(均P0.05)。重度组病死率高于轻度组与正常组,存活患者血Na~+水平高于死亡患者(P0.05)。结论:AMI患者低钠血症程度与CK、CK-MB、cTnI水平、心肌梗死面积、住院30 d病死率呈负相关,与LVEF水平呈正相关。     

入院即刻血糖对急性心肌梗死患者预后的影响

目的：评价急性心肌梗死（acute myocardial infarction,AMI）患者入院即刻血糖（admission plasma glucose,APG）水平与其预后的关系。方法：连续收集2009年至2011年间,于安贞医院心内科住院的AMI患者703例,测量所有患者入院时即刻血糖水平,将患者分为APG≥11.1 mmol/L组（n=443）和APG〈11.1mmol/L组（n=260）。观察住院期间和随访1个月时主要不良心脏事件（major adverse cardiac event,MACE）,包括（死亡、心力衰竭、再次心肌梗死及脑卒中）。结果：APG≥11.1 mmol/L组MACE的发生明显高于APG〈11.1mmol/L组（16.2%vs.5.9%）;随访期间APG≥11.1 mmol/L组MACE的发生明显高于APG〈11.1mmol/L组（4.6%vs.1.9%）;多因素Logistic回归分析显示,APG≥11.1 mmol/L组是总MACE的危险因素（OR=1.266,P=0.005,95%CI：1.066～2.002）。结论：APG与AMI患者近期预后密切相关,是AMI患者早期死亡的独立预测因子。
