Pulse pressure is a strong predictor of cardiovascular risk: Data of the risk factors in impaired glucose tolerance for atherosclerosis and diabetes and the Sofia Metabolic Syndrome studies.

Unlabelled: The aim of the present study was to examine the relationship between pulse pressure (PP), cardiovascular risk factors and intima-media thickness (IMT) in a population at risk for type 2 diabetes and atherosclerosis in Saxony, and to assess the association between PP and history of myocardial infarction in the general population of Bulgaria.

Material And Methods: The Risk factors in IGT for Atherosclerosis and Diabetes (RIAD) study included 1139 subjects, aged 40-70 years, with a family history of type 2 diabetes, obesity and/or hyper/dyslipoproteinemia. The SMS study included 1018 subjects (> 14 years of age) from the general population of Bulgaria.

In type 2 diabetes, rosiglitazone therapy for insulin resistance ameliorates endothelial dysfunction independent of glucose control.

Objective: Insulin resistance is an independent risk factor for arteriosclerosis and cardiovascular mortality. However, the mechanism by which insulin resistance contributes to arteriosclerosis is unknown. Conceivably, endothelial dysfunction could be involved.

Increased cholesteryl ester transfer protein activity in impaired glucose tolerance: relationship to high density lipoprotein metabolism.

Aim: To investigate the mechanisms and dynamics of cholesteryl ester (neutral lipid) transfer protein activity in subjects with impaired glucose tolerance.

Methods: Eighty six Caucasian subjects were recruited by advertisement from the local population between January 1998 and December 1999. The activity of cholesteryl ester transfer protein in 44 non-obese subjects with impaired glucose tolerance (plasma triglycerides 1.

Insulin secretion and insulin sensitivity pattern is different in isolated impaired glucose tolerance and impaired fasting glucose: the risk factor in Impaired Glucose Tolerance for Atherosclerosis and Diabetes study.

Objective: Isolated impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) are two risk categories for type 2 diabetes. This study compared both categories with respect to the degree of insulin secretion abnormalities and insulin resistance.

Research Design And Methods: This is a crossover comparison of a population at high risk for type 2 diabetes.

Influence of treatment with acarbose or glibenclamide on insulin sensitivity in type 2 diabetic patients.

Aim: The aim of our double-blind, placebo-controlled study was to compare the effect of acarbose and glibenclamide on the insulin sensitivity in type 2 diabetes.

Methods: We investigated 77 patients (mean age 58.7 years, mean BMI 27.

In vivo evidence for increased oxidation of circulating LDL in impaired glucose tolerance.

Oxidized LDL (oxLDL) is a key mediator in atherogenesis and a marker of coronary artery disease (CAD). Type 2 diabetes is associated with excessive cardiovascular morbidity and mortality. Because atherogenesis starts before diabetes is diagnosed, we investigated whether circulating oxLDL levels are increased in impaired glucose tolerance (IGT).

Post-challenge hyperglycaemia relates more strongly than fasting hyperglycaemia with carotid intima-media thickness: the RIAD Study. Risk Factors in Impaired Glucose Tolerance for Atherosclerosis and Diabetes.

Aims: Only scarce information exists on the distribution and atherosclerosis risk in different types of hyperglycaemia at diabetes detection. This study aimed to analyse the occurrence of isolated fasting (IFH), isolated post-challenge (IPH) and combined hyperglycaemia (FH/PH) among subjects detected to have diabetes and the association of these types of hyperglycaemia with cardiovascular risk factors and carotid intima-media thickness (IMT).

Methods: A total of 785 middle-aged subjects of the Risk Factors in Impaired Glucose Tolerance (IGT) for Atherosclerosis and Diabetes (RIAD) study underwent a 75-g oral glucose tolerance test and examination of various atherosclerosis risk factors.

Postchallenge plasma glucose and glycemic spikes are more strongly associated with atherosclerosis than fasting glucose or HbA1c level.

Objective: To observe the relationship of fasting plasma glucose (FPG), postchallenge plasma glucose (PG) (30, 60, 90, and 120 min during an oral glucose tolerance test [OGTT], as well as maximal PG during an OGTT, postchallenge glucose spikes [PGS], and glucose under the OGTT curve), and HbA1c to intima-media thickness (IMT) as a marker of atherosclerosis.

Research Design And Methods: OGTT, ultrasound measurement of carotid IMT, and various atherosclerosis risk factors, such as family history of diabetes, obesity, and/or hyperlipoproteinemia, but without known diabetes, were analyzed in 582 individuals aged 40-70 years and at risk for type 2 diabetes.

Results: In univariate analysis, all examined glycemic parameters were significantly correlated to IMT.

Postprandial plasma glucose is an independent risk factor for increased carotid intima-media thickness in non-diabetic individuals.

Postprandial (pp) hyperglycemia--frequently associated with an increase in cardiovascular risk factors--may be damaging for the endothelium. So far, little information exists how glucose, insulin and lipids may affect atherosclerosis in the pp state. Therefore, we evaluated the relationship of pp hyperglycemia, insulin secretion and coronary risk factors to intima-media thickness (IMT) in a non-diabetic risk population.

Relationship between fasting plasma glucose, atherosclerosis risk factors and carotid intima media thickness in non-diabetic individuals.

We analysed the relationship between fasting plasma glucose, carotid intima media thickness and some atherosclerosis risk factors in 307 non-diabetic individuals. Male (n = 120) and female subjects (n = 187) with a familial history of Type II diabetes mellitus and/or obesity and hyperlipoproteinaemia were examined in the age group 40-70 years. Plasma triglycerides, total and high-density-lipoprotein cholesterol, plasminogen activator inhibitor were measured by conventional methods.
