OBJECTIVE Observational studies assessing the association of combination therapy of metformin and sulfonylurea on all-cause and/or cardiovascular mortality in type 2 diabetes have shown conflicting results. We therefore evaluated the effects of combination therapy of sulfonylureas and metformin on the risk of all-cause mortality and cardiovascular disease(More)
OBJECTIVE To systematically investigate the effect of lack of adherence to the recommended change in insulin pump infusion line use beyond 48 h and determine whether the type of insulin made a difference. RESEARCH DESIGN AND METHODS This was a double-blind, randomized, crossover trial with 20 patients with diabetes mellitus I using insulins aspart and(More)
Serum- and glucocorticoid-inducible kinase 1 (SGK1) has a central role in epithelial sodium channel (ENaC)-dependent Na(+) transport in the distal nephron. We hypothesized that SGK1 gene variants may contribute to the effect of dietary salt intake on blood pressure (BP) in humans with hypertension, and consequentially influence renin-angiotensin-aldosterone(More)
Myocardial extracellular matrix expansion and reduced coronary flow reserve (CFR) occur in patients with type 2 diabetes mellitus without heart failure or coronary artery disease. Because aldosterone is implicated in the pathophysiology of cardiac fibrosis and vascular injury, the aim of this study was to test the hypothesis that aldosterone is associated(More)
Reduced coronary flow reserve (CFR), an indicator of coronary microvascular dysfunction, is seen in type 2 diabetes mellitus (T2DM) and predicts cardiac mortality. Since aldosterone plays a key role in vascular injury, the aim of this study was to determine whether mineralocorticoid receptor (MR) blockade improves CFR in individuals with T2DM. Sixty-four(More)
Background Increased levels of the infl ammatory biomarker high-sensitivity C-reactive protein predict cardiovascular events. Since statins lower levels of high-sensitivity C-reactive protein as well as cholesterol, we hypothesized that people with elevated high-sensitivity C-reactive protein levels but without hyperlipidemia might benefi t from statin(More)
Studies have shown associations between exposure to hypoglycemia and increased mortality, raising the possibility that hypoglycemia has adverse cardiovascular effects. In this study, we determined the acute effects of hypoglycemia on cardiovascular autonomic control. Seventeen healthy volunteers were exposed to experimental hypoglycemia (2.8 mmol/L) for 120(More)
BACKGROUND Plasminogen activator inhibitor-1 (PAI-1) is implicated in the pathophysiology of cardiovascular disease (CVD) and increased in individuals with type 2 diabetes mellitus (T2DM). Adipose tissue produces PAI-1, and pericardial fat is a CVD risk factor. We sought to determine the relationship between PAI-1 and pericardial fat in males and females(More)
