应激性高血糖对急性ST段抬高型心肌梗死患者远期预后的影响

目的探讨急性sT段抬高型心肌梗死（STEMI）患者发生应激性高血糖的相关危险因素,并评估应激性高血糖对STEMI患者远期预后的影响。方法白求恩国际和平医院2009年8月至2010年4月92例初次发生STEMI的非糖尿病住院患者,根据入院后测定的空腹血糖或随机血糖分A组（应激性高血糖组）41例和B组（血糖正常组）51例。平均随访1．5年。结果应激性高血糖的发生率是44．6％（41／92）。A和B组间经logistic回归分析提示女性（OR=8．952,P=0．013）、心功Killip分级越高（OR=3．530,P=0．048）、肌酸激酶同工酶（CK．MB）峰值越高（OR=9．408,P〈0．001）均是应激性高血糖发生的相关危险因素。Cox回归对A和B组患者1～2年内发生的死亡风险进行分析,提示应激性高血糖是远期死亡（RR1．532,95％CI1．004--2．337,P=0．048）的独立预测因子。高甘油三酯血症患者远期死亡风险是正常者1．557倍（P=0．041）。结论女性、Killip分级、CK．MB增高是应激性高血糖发生的相关危险因素。应激性高血糖可能是STEMI患者远期预后不良的独立预测因子和危险因素。高甘油三酯血症可能加重患者的死亡风险。

Impact of admission blood glucose levels on prognosis of elderly patients with ST elevation myocardial infarction treated by primary percutaneous coronary intervention

Objective Admission hyperglycemia in acute myocardial infarction (MI) is related with increased in-hospital and long term mortality and major cardiac adverse events. We aimed to investigate how admission hyperglycemia affects the short and long term outcomes in elderly patients (> 65 years) after primary percutaneous coronary intervention for ST elevation myocardial infarction. Methods We retrospectively analyzed 677 consecutive elderly patients (mean age 72.2 ± 5.4). Patients were divided into two groups according to admission blood glucose levels. Group 1: low glucose group (LLG), glucose < 168 mg/dL; and Group 2: high glucose group (HGG), glucose > 168 mg/dL. Results In-hospital, long term mortality and in-hospital major adverse cardiac events were higher in the high admission blood glucose group (P < 0.001). Multivariate regression analysis showed: Killip > 1, post-thrombolysis in MI < 3 and admission blood glucose levels were independent predictors of in-hospital adverse cardiac events (P < 0.001). Conclusions Admission hyperglycemia in elderly patients presented with ST elevation myocardial infarction is an independent predictor of in-hospital major adverse cardiac events and is associated with in-hospital and long term mortality.     

Relation of chronic and acute glycemic control on mortality in acute myocardial infarction with diabetes mellitus

Acute hyperglycemia during myocardial infarction predicts adverse short-term outcomes and mortality in diabetic patients. Conversely, chronic hyperglycemia is associated with an increased incidence of long-term cardiovascular complications, although its effect on acute hyperglycemic response and mortality after acute myocardial infarction is unknown. We investigated the prognostic relation of the glucose concentration at admission and the baseline average glycohemoglobin on acute myocardial infarction mortality. Of 808 consecutive diabetic patients with acute myocardial infarction, the most significant independent predictor of in-hospital mortality was the glucose concentration at admission. Baseline glycohemoglobin strongly correlated with admission hyperglycemia but did not predict mortality independently.     

平均空腹血糖对ST段抬高型心肌梗死患者住院预后的影响

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.     

Influence of abnormal fasting plasma glucose on left ventricular function in older patients with acute myocardial infarction

We assessed whether the admission fasting plasma glucose (FPG) levels were associated with all-cause mortality and left ventricular (LV) function in older patients with acute myocardial infarction (AMI). A total of 1854 consecutive patients were categorized into 4 groups: hypoglycemia, euglycemia, mild hyperglycemia, and severe hyperglycemia. The primary outcomes were in-hospital/3-year mortality and LV function. There was a near-linear relationship between FPG and Killip class. However, no significant correlation was found between FPG levels and LV ejection fraction. Both FPG levels and Killip classes were all independent significant predictors of mortality. Compared with the euglycemia group, both the hypo- and hyperglycemia groups were associated with higher in-hospital and 3-year mortality. In older patients with AMI, the FPG values had differential influences on LV function and mortality. There was a U-shaped relationship between FPG and in-hospital/3-year mortality, and a near-linear relationship between increased admission glucose levels and higher Killip classification.     

Identificación y cuantificación del efecto fin de semana y festivos en la atención del síndrome coronario agudo en el Sistema Nacional de Salud

Introduction and objectivesTo analyze whether admission on weekends or public holidays (WHA) influences the management (performance of angioplasty, percutaneous coronary intervention [PCI]) and outcomes (in-hospital mortality) of patients hospitalized for acute coronary syndrome in the Spanish National Health System compared with admission on weekdays.MethodsRetrospective observational study of patients admitted for ST-segment elevation myocardial infarction (STEMI) or for non–ST-segment elevation acute coronary syndrome (NSTEACS) in hospitals of the Spanish National Health system from 2003 to 2018.ResultsA total of 438 987 episodes of STEMI and 486 565 of NSTEACS were selected, of which 28.8% and 26.1% were WHA, respectively. Risk-adjusted models showed that WHA was a risk factor for in-hospital mortality in STEMI (OR, 1.05; 95%CI,1.03-1.08; P < .001) and in NSTEACS (OR, 1.08; 95%CI, 1.05-1.12; P < .001). The rate of PCI performance in STEMI was more than 2 percentage points higher in patients admitted on weekdays from 2003 to 2011 and was similar or even lower from 2012 to 2018, with no significant changes in NSTEACS. WHA was a statistically significant risk factor for both STEMI and NSTEACS.ConclusionsWHA can increase the risk of in-hospital death by 5% (STEMI) and 8% (NSTEACS). The persistence of the risk of higher in-hospital mortality, after adjustment for the performance of PCI and other explanatory variables, probably indicates deficiencies in management during the weekend compared with weekdays.     

Comparison of outcome of recurrent versus first ST-segment elevation myocardial infarction (from national Israel surveys 1998 to 2006)

Patients with recurrent acute myocardial infarction (AMI), who represent ≤35% of hospitalized patients with AMI, are at an increased risk of complications and death. Our study purpose was to compare the treatment and outcome of patients hospitalized with recurrent acute ST-segment elevation myocardial infarction (STEMI) from 1998 to 2006 with those of patients with a first STEMI. We performed 5 biennial nationwide 2-month surveys during 1998 to 2006, collecting data prospectively from all patients hospitalized for AMI or acute coronary syndrome in all 25 coronary care units in Israel. The present cohort included 4,543 patients with STEMI, 3,679 (76%) with first and 864 (24%) with recurrent STEMI. The patients with recurrent STEMI were older (66 ± 13 vs 62 ± 13 years), had greater rates of diabetes, hypertension, and previous angina, had a worse Killip class on admission, and experienced more in-hospital complications. The all-cause hospital crude mortality rate was 8.1% in patients with recurrent STEMI versus 5.5% in those with a first STEMI (adjusted odds ratio 1.71 95% confidence interval 1.19 to 2.44), and the 1-year mortality rate was 18.9% versus 10.9%, respectively (hazard ratio 1.85, 95% confidence interval 1.41 to 2.43). From 1998 to 2006, an insignificant trend toward a 1-year mortality reduction among patients with recurrent STEMI was seen and those with a first STEMI had a significant mortality decrease. In conclusion, patients admitted for recurrent STEMI have worse in-hospital and 1-year outcomes that did not improve during the study period. An improved therapeutic approach is needed for these high-risk patients.
