Impact of abnormal glucose tolerance, hypertension and other risk factors on coronary artery disease.

BACKGROUND: The degree to which abnormal glucose tolerance contributes to the development of coronary artery disease (CAD) has not been clarified in Japanese. The relationship between abnormal glucose tolerance and severity of coronary artery stenosis, as well as the contributions of hypertension, diabetes and other risk factors for CAD to recurrence of the disease, were investigated in the present study. METHODS AND RESULTS: The subjects were 474 consecutive patients (mean age: 63.8+/-11.3 years) with suspected CAD who were admitted to Sapporo Medical University Hospital during April 1, 1997 to March 31, 2004. The coronary index and stenosis score were higher in subjects with diabetes mellitus (DM) and in subjects with impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) than in subjects with normal glucose tolerance (NGT). Ischemic episodes recurred during the observation period (mean 2.5 years) in 61 of 341 patients diagnosed as having CAD. In the follow-up subjects, systolic blood pressure (SBP) was significantly higher in the recurrence group than in the non-recurrence group, and SBP was a significant variable in logistic regression analysis after adjustment for age, gender, hemoglobin A1c, total cholesterol, body mass index, smoking history, family history and stenosis score. The relative risk of recurrence became 1.7-fold higher with a rise in SBP of 10 mmHg (95% confidence interval: 1.252-2.250). Analysis of the relationship between glucose tolerance and recurrence showed that the rate of recurrence was higher in patients with IFG+IGT+DM than in those with NGT. CONCLUSIONS: CAD progresses not only in patients with DM but also in those with IGT. The rate of recurrence of ischemic episodes increases in individuals with IGT or DM, and suggesting that hypertension is a risk factor for recurrence of ischemic episodes. Management of glucose tolerance and blood pressure is therefore important for prevention of CAD in Japanese.     

Metabolic risk factors in the normolipidemic male patients with angiographically defined coronary artery disease

The relationship of plasma lipid and apolipoprotein (apo) concentrations and plasma insulin response to oral glucose load to angiographically determined coronary artery disease (CAD) was investigated in 65 normolipidemic (plasma cholesterol less than 230 mg/dl and plasma triglyceride less than 150 mg/dl) males. According to the results of coronary angiography, the patients were divided into 2 groups: patients with normal coronary artery, NCA group (n = 21); and patients with coronary artery disease, CAD group (n = 44). No significant differences in concentrations of plasma cholesterol and triglyceride were observed between the CAD and NCA groups. In the CAD group cumulative lifetime tobacco consumption was higher and high density lipoprotein (HDL) cholesterol concentration was lower than those in the NCA group. The variables that correlated with the severity of CAD, defined by the number of lesions and percent stenosis, were levels of plasma apo A-I and apo B. Prevalence of subjects with reduced oral glucose tolerance did not differ between 2 groups. However, hyperinsulinemic response to oral glucose load was present in the CAD group. HDL-cholesterol concentration, the sum of plasma insulin levels and the magnitude of the early insulin response during oral glucose challenge were accurate predictors of the presence of but not the severity of CAD. Multivariate analysis of the data confirmed the independent effect of plasma levels of apo A-I and apo B on the severity of CAD. The present data indicated that plasma levels of apo A-I and apo B were powerful discriminators in the normolipidemic CAD patients and that a high insulin response might be an indicator of enhanced susceptibility to the distinct coronary atherosclerosis.     

Diabetes and impaired glucose tolerance prevalences in Turkish patients with impaired fasting glucose

Impaired fasting glucose (IFG) like impaired glucose tolerance (IGT) has increased risk of progressing to diabetes mellitus (DM). The aim of the study was to evaluate prevalance of IGT and type 2 DM with oral glucose tolerance test (OGTT) in Turkish patients who had fasting glucose of 110 and 125 mg/dl. Hundred and forty-eight (67.3%) women and 72 (32.7%) men (30-65 years old with mean age of 51.3 +/- 8.7 year) who had fasting glucose range 110-125 mg/dl were evaluated with OGTT. Seventy-two patients had IGT (32.8%), 74 (33.6%) patients had type 2 diabetes and 74 (33.6%) patients had normal glucose tolerance (NGT). Mean fasting glucose and insulin levels were higher in the IGT group than in the NGT group. Mean level of total cholesterol was higher in DM than that in NGT and IGT groups. Mean triglyceride (TG) (P = 0.476), high-density lipoprotein (HDL) (P = 0.594), low-density lipoprotein (LDL) (P = 0.612), Apoproteine A (P = 0.876), Apoproteine B (P = 0.518), uric acid (P = 0.948) and ferritin (P = 0.314) were found higher in diabetic patients. Lipoproteine a (P = 0.083), fibrinogen (P = 0.175) and hsCRP (P = 0.621) levels were higher in IGT. Mean HOMA S% levels of NGT, IGT and DM were found to be 65.0 +/- 13.0%, 60.9 +/- 16.0% and 50.1 +/- 11.1%, respectively. HOMA B% levels were measured to be 80.4 +/- 29.1% in NGT, 85.3 +/- 14.59% in IGT and 60.1 +/- 10.1% in DM. Significant difference was found between IFG and DM (P = 0.043) groups. The prevalences of diabetes and IGT were found to be 33.63 and 32.7% in IFG, respectively.

Lipoprotein-related coronary risk factors in patients with angiographically defined coronary artery disease: relation to number of stenosed arteries

To determine whether an index estimating antagonism between low density lipoprotein (LDL) and high density lipoprotein (HDL) would improve separation between groups with and without coronary artherosclerosis, patients undergoing coronary catheterization (35 women and 99 men) were analysed for total cholesterol (TC), HDL cholesterol (HDLc), apolipoprotein A (apo A) and apolipoprotein B (apo B). The subjects were categorized as groups 0, 1, 2 or 3 according to the number of stenosed arteries (greater than 75% areal stenosis). Thirty of the patients showed no significant coronary atherosclerosis (group 0). Serum apo B and TC concentrations were directly related to the number of stenosed vessels, whereas the concentrations of apo A and HDLc were negatively correlated with the number of stenosed arteries. An 'atherogenic Index' (ATH index) calculated as the product of serum concentrations of apo B, and TC minus HDLc divided by the product of apo A and HDLc, proved more satisfactory than individual lipoprotein components for discrimination between subjects with and without stenosis. Accordingly, identification of coronary groups may be improved by using the ATH index.     

The influence of changes in lipid values induced by cholestyramine and diet on progression of coronary artery disease: results of NHLBI Type II Coronary Intervention Study

The National Heart, Lung and Blood Institute Type II Coronary Intervention Study, a double-blind, placebo-controlled trial, evaluated the efficacy of reduction in cholesterol levels induced by cholestyramine on progression of coronary artery disease (CAD). The rate of CAD progression in patients treated with cholestyramine plus diet was compared with that of patients treated with placebo plus diet. CAD progression was defined angiographically. Significant decrease in total cholesterol (TC) and low-density lipoprotein cholesterol (LDLc) and increases in high-density lipoprotein cholesterol (HDLc), as well as in HDLc/TC and HDLc/LDLc ratios, were observed with cholestyramine. HDLc change was due to increase in HDL2A and HDL2B. When the relationship between CAD progression and lipid changes was examined independent of specific treatment group, a significant inverse relationship was found between progression at 5 years and the combination of an increase in HDLc and a decrease in LDLc; changes in HDLc/TC and HDLc/LDLc were the best predictors of CAD change. While the testing of these relationships independent of treatment group was not part of the initial study design, the trends were observed in both the placebo-treated and cholestyramine-treated groups. Moreover, with multivariate analysis, the effect of cholestyramine treatment on CAD progression was eliminated by adding changes in HDLc/TC to the regression model. These findings support the hypothesis that increases in HDLc and decreases in TC (or LDLc) can prevent or delay CAD progression.     

糖代谢异常、NO、CRP及颈动脉内膜中层厚度之间关系的研究

目的研究从糖耐量正常、糖耐量低减至糖尿病发展过程中血一氧化氮(NO)、超敏C-反应蛋白(CRP)的变化,探讨其与糖尿病早期动脉硬化颈动脉内膜中层厚度(intimal-medialthickness,IMT)的关系。方法90例患者,其中糖耐量正常、糖耐量低减、2型糖尿病各30例,每例均晚间禁食后抽血行包括NO、CRP在内的生化检查及超声检测颈动脉内膜中层厚度。结果从糖耐量正常、糖耐量低减至糖尿病,随着糖代谢异常的加重,颈动脉内膜中层逐渐增厚、血NO逐渐降低、CRP逐渐升高(P<0.05或P<0.01)。结论糖代谢异常早期即有血管内皮损伤、炎症反应等变化,并参与了糖尿病动脉硬化的整个进程,因此早期控制血糖、稳定血管内皮损伤、抑制炎症反应,对于延缓、减少糖尿病晚期动脉硬化等并发症具有重要的作用。     

Lipoprotein predictors of the severity of coronary artery disease in men and women

In this study we examined the relationships between levels of several components of plasma lipoproteins and severity of coronary artery disease in 65 men and 42 women who underwent coronary arteriography for suspected coronary disease. Severity of coronary atherosclerosis was scored as the extent of disease seen at arteriography. Univariate analyses of the relationships between the plasma lipoprotein parameters and score for severity of atherosclerosis revealed a marked difference between men and women. In men, the score for severity of atherosclerosis was strongly related to the low-density lipoprotein (LDL) cholesterol and apolipoprotein B concentrations, whereas in women it was related to the triglyceride concentrations in plasma intermediate-density lipoprotein (IDL) and LDL and to the cholesterol and apolipoprotein B concentrations in IDL. The significance of these correlations was not negated by possible confounding factors such as alcohol intake, diabetes, and treatment with thiazides and beta-adrenergic blockers. Stepwise regression analyses of data adjusted for weight and age indicated that 22% of the variation in the score for severity of atherosclerosis could be accounted for by levels of LDL cholesterol in men. No other lipoprotein parameter could account for any further variation. In contrast, cholesterol did not account for any variation in the score for severity of atherosclerosis in women, whereas plasma triglyceride accounted for 16% of the observed variation in this group. No relationships were found between score for severity of atherosclerosis and high-density lipoprotein cholesterol or plasma apolipoprotein A-I concentrations in either group.(ABSTRACT TRUNCATED AT 250 WORDS)

Multiple regression analysis of sixteen risk factors including serum apolipoproteins in angiographically documented coronary artery disease

Multiple regression analysis of 16 risk factors, including serum apolipoproteins in angiographically measured coronary stenosis, was carried out in 239 consecutive patients (159 males and 80 females, ranging in age from 30-80 years and mean 56.4 years) who underwent coronary angiography for suspected coronary artery disease during the past five years (1981-1985). The risk factors (independent variables) were age, total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), HDL-C/TC, apolipoprotein (Apo) A-I, A-II, B, C-II, C-III, E, YRSMOK (average number of packs per day X years of smoking), weight index (WI), glucose tolerance (GT), and blood pressure (BP). Severity of coronary atherosclerosis was scored as the extent of disease seen at arteriography (coronary score: CS). The order of importance of risk factors to CS in the five groups of subjects studied were as follows. (1) All patients: YRSMOK greater than Apo A-I greater than TC greater than GT, (2) Male group: Apo A-I greater than TC greater than Age greater than GT, (3) Female group: TC, (4) Young group (age below 54 years): BP greater than YRSMOK, and (5) Old group (age over 55 years): YRSMOK greater than TG greater than TC greater than GT. The results clearly indicated the importance of Apo A-I but not other apolipoproteins including Apo B in males, and that of blood pressure in the young group of the patients studied.     

Prevalence of glucose intolerance in primary hyperparathyroidism and the benefit of parathyroidectomy

BACKGROUND: Increased prevalence of diabetes mellitus (DM) in primary hyperparathyroidism (PHPT) is established, but not glucose intolerance (GI), nor benefit from parathyroidectomy on GI. We determined these during management of a continuous series of patients with PHPT routinely followed after surgery. PATIENTS AND METHODS: WHO criteria classified 75 g oral glucose tolerance tests (OGTT) in 51/54 consecutively proven PHPT patients, into normal glucose tolerance (NGT), DM, impaired glucose tolerance (IGT) or impaired fasting glucose (IFG); GI was derived by adding those with DM and IGT/IFG. OGTT were repeated after parathyroidectomy (mean follow up 2.4 +/- SD 1.6 years). Paired student t tests were used to compare fasting and 2-h plasma glucose (PG). RESULTS: At presentation 32/54 patients (59%) had NGT, 10 IGT/IFG (19%) and 12 type 2 DM (22%), nine newly diagnosed. Before parathyroidectomy 17/35 patients had NGT (49%), 18 GI (51%), 12 DM (34%) and 6 IGT/IFG (17%). Five out of six patients with IGT/IFG had NGT, one with NGT developed IGT. At completion 23 patients (66%) had NGT, 12 GI (34%), 4 IGT/IFG (11%) and 8 DM (23%). After parathyroidectomy fasting and 2-h. PG fell in 30/34 normocalcaemic patients not on hypoglycaemic agents, 5.6 +/- 1.0 to 5.4 +/- 0.8 mmol/l, 7.2 +/- 3.0 to 6.3 +/- 3.1 mmol/l (p < 0.05, p < 0.01). CONCLUSIONS: 1.At presentation with PHPT, OGTT commonly identifies Type 2 DM and GI.2.After successful parathyroidectomy fasting and 2-h. PG fall significantly (p < 0.05, p < 0.01). DM and IGT/IFG often ameliorates to IGT or NGT, persistently.
