More than half of US adults—approximately 137 million—are candidates for semaglutide based on diabetes, weight management, or cardiovascular prevention indications.

DIGAMI 2 trial post hoc analysis: Lessons in overinterpretation
December 17th 2008In their post hoc analysis of the DIGAMI 2 (Diabetes Mellitus Insulin-Glucose Infusion in Acute Myocardial Infarction 2) study, Mellbin and colleagues suggest that insulin therapy after myocardial infarction (MI) may be associated with increased clinical events (not mortality), whereas metformin therapy may be associated with reduced events and sulfonylurea therapy with neutral effects.
Impact of diabetes development on atrial fibrillation in hypertensive patients
Patients with new-onset diabetes mellitus in the VALUE (Valsartan Antihypertensive Long-term Use Evaluation) trial had an increased incidence of atrial fibrillation compared with patients without diabetes. Clustering of risk factors or the presence of dysglycemia may make the heart more susceptible to arrhythmias.
Insulin as a strategy to optimize glycemic control in patients with type 2 diabetes
November 14th 2008Treatment of type 2 diabetes should achieve and maintain euglycemia, thereby preventing complications from this progressive disease. Current antidiabetic therapies should be a part of a multimodal management program that includes diet, exercise, and blood pressure and lipid control. Oral antidiabetic drugs are still first-line therapy for type 2 diabetes, but intensification of therapy, including starting insulin, should occur every 2 to 3 months as needed to achieve euglycemia. The first insulin added is typically a basal insulin, which is effective in lowering fasting plasma glucose (FPG). A persistently elevated glycated hemoglobin (HgbA1C) level despite near or complete normalization of FPG, however, indicates postprandial hyperglycemia. In these cases, the addition of bolus insulin is required to reduce postprandial glucose (PPG). Several approaches to initiate and titrate insulin can be used based on FPG, PPG, HgbA1C, and patient factors.
Glycemic control and CVD outcomes: Randomized clinical trials in 2008
November 14th 2008The relationship of glucose levels to cardiovascular disease (CVD) risk, especially coronary heart disease (CHD), in observational data sets has been the subject of several studies. These studies have shown that the relationship between fasting (and postprandial glucose) and CHD risk is continuous and graded, and that this relationship extends below the currently defined threshold for diagnosing diabetes mellitus. The assumption has been that glycemic control in patients with diabetes mellitus should favorably affect CVD outcomes in randomized clinical trials; however, the results of several large trials have not consistently confirmed this hypothesis. In fact, ACCORD (Action to Control Cardiovascular Risk in Diabetes) data suggest a small increased risk in mortality for patients at high risk for CHD events.
Incidence of death and MI associated with stopping clopidogrel after ACS
October 21st 2008Rates of death and myocardial infarction were assessed for a national sample of acute coronary syndrome patients after stopping clopidogrel. In the first 90 days after stopping treatment, patients experienced a nearly twofold increased risk of adverse events compared with subsequent follow-up intervals for patients treated medically without stents and for patients treated with coronary stents. This suggests a possible clopidogrel rebound effect, but additional studies are needed to support this hypothesis and to identify strategies to reduce early events after clopidogrel cessation.
Intensive glycemic control has no effect on cardiovascular disease in type 2 diabetes
October 16th 2008The benefits of intensive glycemic control appear to be confined to microvascular disease, with 3 randomized controlled clinical trials failing to demonstrate a macrovascular benefit with intensive glycemic control in patients with type 2 diabetes.
Sex-related differences in treatment and outcome in patients with ACS
September 26th 2008The AMIS (Acute Myocardial Infarction in Switzerland) Plus prospective cohort study compared treatment and in-hospital outcomes between men and women with acute coronary syndrome (N = 26,452) admitted to Swiss hospitals between 1997 and 2007. The study reached several important conclusions: women had different baseline characteristics than men at admission, were treated with different drug regimens, and were significantly less likely to undergo percutaneous coronary intervention. After adjusting for these differences, researchers found no significant difference in the rates of in-hospital mortality between men and women, except for women aged 51 to 60 years, who were more likely to die in-hospital.
Revascularization in patients 75 years or older with diabetes mellitus and angina pectoris
September 24th 2008We analyzed the results of the Trial of Invasive Versus Medical Therapy in the Elderly with Chronic Coronary Artery Disease (TIME) in which invasive treatment was compared with optimized medical treatment in patients with chronic angina aged 75 years and older. Patients with diabetes had higher mortality than nondiabetic patients, but revascularization improved overall survival similarly in diabetic and nondiabetic patients.
