Independent predictors of the severity of angiographic coronary atherosclerosis: the lack of association between impaired glucose tolerance and stenosis severity

Independent predictors of the severity of coronary atherosclerosis are ill defined. We sought to determine the predictors and examine the association of impaired glucose tolerance with stenosis severity. Four hundred thirty-seven patients were studied who underwent coronary angiography for suspected coronary artery disease. Serum concentrations of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDLc), lipoprotein(a) [Lp(a)] and apolipoproteins (Apo A-I and Apo B) were measured and low-density lipoprotein cholesterol (LDLc) concentration was calculated. Except the patients treated for diabetes mellitus (DM), patients were classified into three groups such as normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and DM by glucose tolerance test. Coronary atherosclerosis index (CAI) representing the severity of coronary atherosclerosis was determined by summation of the stenosis score of all lesions on coronary angiograms. Results indicated that age, total amount of cigarettes smoked, Apo B/Apo A-I, and LDLc/HDLc correlated with CAI, whereas HDLc and Apo A-I concentrations inversely correlated with CAI. TC, TG, Lp(a), LDLc, Apo B concentrations and body mass index did not correlate with CAI. One- and two-hour plasma glucose concentrations and the area of plasma glucose concentration under the curve at the glucose tolerance test did not correlate with CAI, revealing that post-challenge glycemia is not associated with stenosis severity. CAI in IGT patients was significantly lower than that in DM patients but did not differ from that in NGT patients, indicating that IGT does not affect the stenosis severity. Multivariate analysis showed that age, male gender, Apo B/Apo A-I, DM, systemic hypertension, and total amount of cigarettes smoked were independent predictors of CAI.     

高血压病人无症状性颅内动脉狭窄的分布特征和危险因素

Association between isolated hypercholesterolemia, isolated hypertriglyceridemia and coronary artery disease in south Indian type 2 diabetic patients

Very high prevalence rates of coronary artery disease have been reported among Indians. The aim of this study was to determine the relative importance of isolated hypercholesterolemia, isolated hypertriglyceridemia, isolated high low-density lipoprotein and isolated low high-density lipoprotein in coronary artery disease among South Indian type 2 diabetic subjects. The study group comprised of 17,885 type 2 diabetic patients attending our institute. A history of documented myocardial infarction was considered as the diagnostic criteria for coronary artery disease. Isolated hypercholesterolemia was defined as serum cholesterol over 200 mg/dL with normal serum triglyceride levels (< or = 200 mg/dL); isolated hypertriglyceridemia was defined as serum triglyceride level over 200 mg/dL with normal serum cholesterol levels (< or = 200 mg/dL). Isolated low high-density lipoprotein was defined as one below 35 mg/dL with normal serum triglyceride levels. Isolated high low-density lipoprotein cholesterol was defined as one over 150 mg/dL with normal serum triglyceride levels. Normolipidemia was defined as serum cholesterol and serum triglyceride both upto 200 mg/dL, high-density lipoprotein 35 mg/dL or above and low-density lipoprotein upto 150 mg/dL. The prevalence of coronary artery disease was significantly high among patients with isolated hypercholesterolemia (4.1%; p < 0.001), isolated high low-density lipoprotein (4.5%; p < 0.001) and isolated low high-density lipoprotein (3.9%; p = 0.005) compared to normolipidemic individuals (2.8%), but not in those with isolated hypertriglyceridemia (3.4%). The odds ratios for coronary artery disease increased with each quartiles of isolated cholesterol, isolated low-density lipoprotein cholesterol and total cholesterol to high-density lipoprotein ratio and reached statistical significance in the last quartile (p < 0.05). There was no significant increase in the odds ratios for coronary artery disease in relation to quartiles of isolated triglycerides. For isolated low high-density lipoprotein, when the last quartile was taken as the reference, the odds ratio for coronary artery disease in the first quartile reached statistical significance (p = 0.03). Multivariate regression analysis revealed age (odds ratio 1.06; p < 0.001), male sex (odds ratio 1.7; p < 0.001), hypercholesterolemia (odds ratio 1.26; p = 0.07) and high low-density lipoprotein levels (odds ratio 1.22; p = 0.043) to be strongly associated with coronary artery disease. Among South Indian type 2 diabetic subjects, serum isolated hypercholesterolemia and high low-density lipoprotein cholesterol but not isolated hypertriglyceridemia appear to be associated with coronary artery disease.     

Regulation of high‐density lipoprotein by inflammatory cytokines: establishing links between immune dysfunction and cardiovascular disease

Coronary artery disease is a primary co‐morbidity in metabolic diseases such as metabolic syndrome, diabetes and obesity. One contributing risk factor for coronary artery disease is low high‐density lipoprotein‐cholesterol (HDLc). Several factors influence steady‐state HDLc levels, including diet, genetics and environment. Perhaps more important to coronary artery disease is factors that attribute to the dynamics of reverse cholesterol transport, storage, and excretion of excess cholesterol. HDLc biogenesis, clearance and innate ability to serve as a cholesterol acceptor and transporter all contribute to HDLc's function as a negative regulator of cardiovascular disease. With the recent failure of torcetrapid, focus is being placed on HDLc biology and its role in various metabolic diseases. Low HDLc levels are often associated with an increased state of background inflammation. Recently, several syndromes with clear pro‐inflammatory components have been shown to be inversely correlated with low HDLc levels in the absence of obesity, diabetes and metabolic syndrome. Early studies with HDLc during the acute‐phase response suggest that HDLc is substantially physically modified during acute infection and sepsis, and recent studies show that HDLc is physically modified by chronic pro‐inflammatory disease. In this review, several of these connections are described and cytokine signalling related to HDLc is examined. Copyright © 2010 John Wiley & Sons, Ltd.     

糖代谢异常和糖尿病患者血浆纤维蛋白原的观察

目的探讨血浆纤维蛋白原在糖代谢异常和糖尿病患者中的变化。方法对155例糖尿病、糖代谢异常患者和正常对照者进行血浆纤维蛋白原、空腹血糖、总胆固醇、三酰甘油、高密度脂蛋白胆固醇、尿素氮和血肌酐检测。结果糖尿病、糖代谢异常和正常对照组之间纤维蛋白原和三酰甘油在各组之间比较差异有统计学意义(P<0.01或P<0.05);纤维蛋白原的多因素linear regression分析发现空腹血糖、三酰甘油是纤维蛋白原的相关因子(P<0.05)。结论糖尿病和糖代谢异常患者血浆纤维蛋白原升高,而且纤维蛋白原与空腹血糖水平相关。因此,血浆纤维蛋白原升高可能参与糖尿病患者心脑血管疾病的形成。     

Effect of hypertriglyceridemia in dyslipidemia‐induced impaired glucose tolerance and sex differences in dietary features associated with hypertriglyceridemia among the Japanese population: The Gifu Diabetes Study

Aims/IntroductionThe mechanisms underlying hypertriglyceridemia‐induced impaired glucose tolerance in Japanese individuals remain unclear. We aimed to evaluate the effect of hypertriglyceridemia on glucose metabolism in comparison with that of increased low‐density lipoprotein or decreased high‐density lipoprotein levels and to elucidate the sex differences in hypertriglyceridemia‐related dietary intake among Japanese individuals.Materials and MethodsWe randomly selected 898 (384 men and 514 women) participants aged 40–78 years in the Gifu Diabetes Study; those taking medication for dyslipidemia or diabetes mellitus were excluded. Serum levels of glucose metabolism parameters and the food frequency were measured cross‐sectionally. The glycated hemoglobin was measured again after 5 years.ResultsGlucose metabolism parameters and the percentage of individuals with impaired glucose tolerance were significantly higher in the high triglyceride group in men and women. Similar trends were observed in the low high‐density lipoprotein group, but only in men. Meanwhile, only the homeostasis model assessment of insulin resistance was higher in the high low‐density lipoprotein group. In non‐obese men, the percentage of energy intake from alcohol per total daily energy intake was significantly greater in the high triglyceride group. In obese women, the total energy intake was significantly greater in the high triglyceride group. At the 5‐year follow up, the risk of elevated glycated hemoglobin levels with hypertriglyceridemia was increased in men.ConclusionsHypertriglyceridemia is a stronger risk factor for impaired glucose tolerance than increased low‐density lipoprotein or decreased high‐density lipoprotein. For dietary habits, increased daily alcohol energy intake in non‐obese men and increased total energy intake in obese women were associated with hypertriglyceridemia.
