Total testosterone levels, metabolic parameters, cardiac remodeling and exercise capacity in coronary artery disease patients with different stages of glucose tolerance.

Objective And Methods: The correlation between total testosterone levels, exercise capacity, and metabolic and echocardiographic parameters was studied in 1097 male subjects with coronary artery disease (CAD) and different stages of glucose tolerance.

Results: Testosterone level was the lowest among diabetics as compared to prediabetics or controls (P < 0.001).

High serum fasting peptide YY (3-36) is associated with obesity-associated insulin resistance and type 2 diabetes.

We studied whether serum fasting levels of active form of peptide YY (PYY), PYY(3-36), are associated with obesity and related phenotypes. The study population consisted of 428 patients with coronary artery disease and diagnosed type 2 diabetes and 440 patients with coronary artery disease but without evidence of diabetes from the ARTEMIS study. The patients were recruited from the consecutive series of patients undergoing coronary angiography in the Oulu University Hospital.

High plasma immunoglobulin (Ig) A and low IgG antibody titers to oxidized low-density lipoprotein are associated with markers of glucose metabolism.

Context: Plasma oxidized low-density lipoprotein (OxLDL) is known to be associated with obesity, metabolic syndrome, and diabetes.

Objective: The objective of the study was to investigate the association between plasma IgA, IgM, and IgG titers to OxLDL, phosphocholine (PC), and streptococcal cell wall polysaccharide (CWPS) and markers of glucose metabolism, type 2 diabetes, and liver adiposity.

Setting And Participants: A population-based cohort of middle-aged Finns (n = 1039) participated in the study.
