  • Correlation between Glycosylated Hemoglobin A1c and Severity of Coronary Artery Lesions in Young Men with Acute Myocardial Infarction

    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.

  • Correlation between Hematocrit and Slow Coronary Flow in Male Patients

    Objective To explore the correlation between hematocrit and slow coronary flow (SCF) in male patients. Methods We studied 205 patients with angiographically no more than one stenosis lt;40% in each major coronary artery who had admitted to the department of cardiology of the Beijing Anzhen Hospital Affiliated to Capital Medical University from August 2011 to August 2012. According to the level of hematocrit, 101 patients were classified into the trial group whose hematocrit was more 42.9%, while 104 patients into the control group whose hematocrit was no more than 42.9%. Clinical variables were analyzed and compared between the two groups. Results The age was younger in the trial group than the control group, whereas the levels of white blood cell count, mean platelet volume, triglyceride, low-density lipoprotein cholesterol, left anterior descending artery (LAD) and right coronary artery (RCA) TIMI frame count and the proportion of SCF in the LAD were higher in the trial group than in the control group (Plt;0.05). The results of correlation analysis showed that, LAD TIMI frame count (r=0.238, P=0.001), proportion of SCF in the LAD (r=0.206, P=0.003) and RCA TIMI frame count (r=0.209, P=0.003) were positively correlated with hematocrit. The results of multivariate analysis (using logistic regression with adjusted confounding factors such as age) showed that, LAD TIMI frame count (OR=1.031, 95%CI 1.006 to 1.056, P=0.014), proportion of SCF in the LAD (OR=1.919, 95%CI 1.038 to 3.547, P=0.038) were independently correlated with hematocrit. Conclusion The proportion of SCF in the LAD is independently correlated to hematocrit, which suggested that increased hematocrit may contribute to the pathophysiological change of SCF in male patients.

  • Levels of Plasma Fibrinogen, Serum Bilirubin, Uric Acid and Mild Stenosis of Coronary Artery: A Relationship Analysis

    Objective To study the relationship between the levels of plasma fibrinogen, serum bilirubin, uric acid and mild stenosis of coronary artery. Methods Patients with suspected myocardial ischemia who underwent coronary angiography in our hospital were divided into the coronary artery mild stenosis group and the normal control group according to the result of coronary arteriongraphy between April 2007 to May 2009. Logistic regression was used to identify the risk factor of mild stenosis of coronary artery. Results Two-hundred and seventy-nine patients involving 191 patients with mild stenosis of coronary artery and 88 patients with normal coronary artery were included. The factors of gender, age, history of hypertension or diabetes mellitus, smoking history, systolic blood pressure, levels of plasma fibrinogen and serum creatinin were significantly different between the two groups. Multivariate logistic regression models found that the factors of age (OR=1.084, 95%CI 1.040 to 1.129, Plt;0.001), hypertension (OR=3.025, 95%CI 1.462 to 6.261, P=0.003), diabetes mellitus (OR=2.519, 95%CI 1.066 to 5.951, P=0.035), smoking history (OR=5.412, 95%CI 2.186 to 13.401, Plt;0.001), plasma fibrinogen (OR=1.748, 95%CI 1.059 to 2.885, P=0.029), serum bilirubin (OR=0.599, 95%CI 0.418 to 0.858, P=0.005), and high-density lipoprotein (HDL) cholesterol (OR=0.219, 95%CI 0.049 to 0.985, P=0.048) were independently associated with mild stenosis of coronary artery. By contrast, the level of serum uric acid was not associated with mild stenosis of coronary artery. Conclusion Except for traditional risk factors, levels of fibrinogen and bilirubin are independent risk factors of mild stenosis of coronary artery.

  • A Study of Risk Factors of Hyperuricemia in Patients with Mild Coronary Artery Stenosis

    Objective To study the risk factors of hyperuricemia in patients with mild coronary artery stenosis. Methods The clinical data of 267 patients, who underwent coronary angiography, were collected and classified into the hyperuricemia group (58.5±8.0 years) and the normal control group (57.3±9.9 years). The coronary artery diameter stenosis of all the patients was lower than 50%. Results Elevated levels of body mass index (BMI), serum creatinine, triglyceride, low level of high-density lipoprotein, and history of hypertension or diabetes mellitus were significantly correlated with increased prevalence of hyperuricemia in patients with mild coronary artery stenosis. Multivariate logistic regression models found that the risk factors were diabetes mellitus (OR=1.999, 95%CI 1.087 to 3.678) , BMI (OR=1.110, 95%CI 1.009 to 1.221), hypertriglyceridemia (OR=1.237, 95%CI 1.023 to 1.496), and serum creatinine (OR=1.026, 95%CI 1.008 to 1.045). Conclusion Diabetes mellitus, BMI, hypertriglyceridemia and serum creatinine are independent risk factors of hyperuricemia in patients with mild coronary artery stenosis.
