Clinical implications of cardiovascular outcome trials in type 2 diabetes
Abstract
Cardiovascular disease (CVD) is the main reason for premature death in patients with type 2 diabetes. Hyperglycemia, the hallmark of diabetes, has long been considered the link between diabetes and CVD, and many trials focused on preventing CVD manifestations by means of tight glucose control. However, diabetes is a multifactorial disease in which, e. g., insulin resistance, endothelial dysfunction, and factors such as hypertension and dyslipidemia contribute. Thus, treatment needs to be multifactorial and take cardiovascular aspects into account. Newer classes of drugs, originally launched for glucose lowering, among them dipeptidyl-peptidase (DPP)-4 inhibitors, sodium-glucose cotransporter (SGLT)-2 inhibitors, and glucagon-like peptide (GLP)-1 receptor agonists, have been studied in large cardiovascular outcome trials (CVOT). Several SGLT-2 inhibitors and GLP-1 receptor agonists are associated with a reduction of cardiovascular events (cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke). Although the mechanisms behind the effects are not fully understood, an important reason for the benefits of SGLT-2 inhibitors seems be a reduction in heart failure, while GLP-1 receptor agonists may retard the developm...Continue Reading

Cardiovascular Disease Pathophysiology
Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
