Objective To investigate the correlation between glycosylated hemoglobin A1c (HbA1c) and severity of coronary artery lesions in young men with acute myocardial infarction (AMI). Methods Total 278 young men with AMI less than 45 years old were retrospectively studied, and all of them were admitted to hospital from January 2009 to December 2011, and had undergone coronary angiography. According to the results of coronary angiography, the patients were divided into three groups based on the number of artery lesions: the single group (156 cases), the double group (64 cases) and the triple group (58 cases). The relationship between the severity of coronary artery lesions and the following factors were observed: HbA1c, systolic blood pressure (SBP), diastolic blood pressure (DBP), hemoglobin (Hb), serum uric acid (UA), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), body mass index (BMI), smoking history, drinking history and family history of early coronary artery disease. Results a) HbA1c levels were gradually raised in all the three groups, but the single group (6.39±1.67%) was significantly lower than the double group (6.91±1.63%) and the triple group (7.41±2.12%), with significant differences (Plt;0.05); the HbA1c level of the single group was significantly lower than the triple group in both the ST-segment elevation AMI (6.42±1.68% vs. 7.17±1.86%, Plt;0.05) and the non-ST-segment AMI (5.57±0.37% vs. 8.56±2.83%, Plt;0.05); the HbA1c level of the single group was significantly lower than the triple group in patients with diabetes millitus (8.31±1.83% vs. 8.59±2.02%, Plt;0.05) and in patients without diabetes millitus (5.56±0.33% vs. 5.74±0.37%, Plt;0.05); b) There were significant differences in SBP, TC, HDL-C, LDL-C and drinking history between the single group and the other two groups (all Plt;0.05), and there were significant differences in DBP and TG between the single group and the double group (all Plt;0.05); and c) The results of logistic regression analysis showed that, LDL-C (OR=1.790), HbA1c (OR=1.287) and SBP (OR=1.042) were the independent risk factors (all Plt;0.05) for multiple lesions in coronary arteries of young men with AMI. Conclusion Glycosylated hemoglobin A1c is an independent risk factor for multiple lesions in coronary arteries of young men with AMI.
Based on literatures on Meta-analysis and randomized controlled trial, drug use and some geriatrics syndromes such as cognitive impairment and depression, in elderly diabetic patients were reviewed. Insulin plus oral hypoglycemic drugs was more rational therapy for insulin resistance and islet dysfunction in type 2 diabetes mellitus. We should pay more attention to cognitive impairment and depression in elderly type 2 diabetic patients.
【摘要】 目的 探讨果糖胺（fructosamine，FMN）与血糖、糖化血红蛋白（HbA1c）的关系。 方法 2009年5月-2009年8月，以75例糖尿病患者作为糖尿病组，36例健康志愿者作为正常对照组，进行口服糖耐量试验，检测其空腹血糖及餐后2 h血糖水平，并同时检测FMN与HbA1c水平。 结果 糖尿病组空腹血糖、餐后2 h血糖、FMN、HbA1c均高于正常对照组（Plt;0.05）。FMN与HbA1c、空腹血糖、餐后2 h血糖均呈正相关关系（Plt;0.05）。FMN与空腹血糖的相关系数高于HbA1c与空腹血糖的相关系数，FMN与餐后血糖的相关系数也高于HbA1c与餐后血糖的相关系数。 结论 果糖胺与HbA1c相比有一定的优势，可作为监测糖尿病患者血糖控制的良好指标。【Abstract】Objective To investigate the association among fructosamine (FMN) and blood glucose, glycated hemoglobin (HbA1c). Methods From May 2009 to April 2009, 75 diabetes and 36 health subjects were recruited for this study. Blood samples was collected and assayed for FMN, HbA1C, and fasting glucose.The 2-hour oral glucose tolerance test (OGTT-2h) was given. Results Fasting glucose, OGTT-2h glucose, FMN and HbA1c were all higher in diabetes group than in healthy control group (Plt;0.05) .There was positive correlation between FMN and fasting glucose, OGTT-2h glucose, and HbA1c (Plt;0.05). The correlation coefficients between FMN and glucose were higher than those between HbA1c and glucose. Conclusion Compared with HbA1c, FMN has advantage in monitoring blood glucose in diabetes and be regarded as a suitable index for blood glucose control.
ObjectiveTo study the correlation of postoperative cognitive dysfunction (POCD) with type-2 diabetes and glycosylated hemoglobin (HbA1c) levels in elderly patients. MethodsA total of 140 elderly patients who were going to undergo non-cardiothoracic surgery in our hospital between January 2011 and February 2013 were included in this study.ASA classification was between I and Ⅲ.There were 78 males and 62 females,aged between 65 and 86 years old.Group A had 70 patients with diabetes,while group B had another 70 corresponding patients without diabetes.One day before surgery and a week after surgery,Mini-mental State Examination (MMSE) and Montreal Cognitive Functioning Scale (MoCA) were used to test patients'cognitive function,and the incidence of POCD was compared between the two groups.Group A patients,according to HbA1c levels,were divided into group AH (HbA1c>7.5%) and group AL (HbA1c<7.5%).And we compared the relationship between group AL and group B,and the relationship between group AH and group B. ResultsThe incidence of POCD in group A was significantly higher than that in group B (P<0.05).Group AH had a significantly higher incidence of POCD than group AL (P<0.05).No significant difference was found in fasting plasma glucose among the groups. ConclusionElderly diabetic patients with poor glycemic control is a risk factor for POCD occurrence,but fasting glucose as a predictor of POCD is not as good as HbA1C.
ObjectiveTo systematically review the diagnosis value of glycosylated hemoglobin (HbA1c) in diagnosis of gestational diabetes mellitus (GDM).MethodsThe diagnostic studies concerning glycosylated hemoglobin in gestational diabetes were electronically searched in EMbase, PubMed, The Cochrane Library, CNKI, WanFang Data and VIP from inception to October, 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies by QUADAS-2 standard. Meta-analysis was performed by RevMan 5.3 and Meta-Disc 1.4 software.ResultsA total of 33 studies involving 16 622 persons were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive predictive value, negative predictive value, the pooled DOR of HbA1c were 0.75 (95%CI 0.74 to 0.77), 0.91 (95%CI 0.90 to 0.91), 8.21 (95%CI 5.41 to 12.46), 0.18 (95%CI 0.11 to 0.28), 45.10 (95%CI 29.70 to 68.48), respectively. The AUC of SROC was 0.933 5. Subgroup analysis by different HbA1c measurements indicated that little variations between different measurements in sensitivity and specificity.ConclusionHbA1c in GDM diagnosis has high sensitivity and specificity. Due to the limited quality and quantity of included studies, the above results should be validated by more studies.
