Abstract

Insights

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) reduce all-cause and cardiovascular mortality in type II diabetes patients. These agents do not increase the risk of atrial or ventricular arrhythmias and sudden cardiac death.

Area of Science:

  • Cardiology
  • Endocrinology
  • Pharmacology

Background:

  • Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely used for type II diabetes management.
  • The cardiovascular effects of GLP-1 RAs remain incompletely understood.
  • Assessing GLP-1 RA impact on mortality and arrhythmias is crucial for patient care.

Purpose of the Study:

  • To evaluate the effect of GLP-1 RAs on mortality, including all-cause and cardiovascular causes.
  • To determine the association between GLP-1 RA use and the risk of atrial and ventricular arrhythmias.
  • To investigate the impact of GLP-1 RAs on sudden cardiac death incidence.

Main Methods:

  • A comprehensive literature search was conducted across multiple databases (MEDLINE, EMBASE, Scopus, Web of Science, Google Scholar, CINAHL) up to May 2022.
  • Included randomized controlled trials (RCTs) comparing GLP-1 RAs (albiglutide, dulaglutide, exenatide, liraglutide, lixisenatide, semaglutide) with control groups.
  • Data from 44 RCTs involving 78,702 patients were analyzed for mortality and arrhythmia outcomes.

Main Results:

  • GLP-1 RA use was associated with a significantly lower risk of all-cause mortality (OR 0.891, P < 0.01).
  • A reduced risk of cardiovascular mortality was observed in patients treated with GLP-1 RAs (OR 0.88, P < 0.01).
  • No significant increase in the risk of atrial arrhythmias (OR 0.963, P = 0.46) or ventricular arrhythmias and sudden cardiac death (OR 0.895, P = 0.36) was found.

Conclusions:

  • GLP-1 receptor agonists demonstrate a favorable impact on mortality in type II diabetes.
  • These findings suggest GLP-1 RAs can be safely used without increasing the risk of major cardiac arrhythmias.
  • GLP-1 RAs represent a valuable therapeutic option for managing type II diabetes with potential cardiovascular benefits.

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Oral Hypoglycemic Agents: Glinides

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Oral Hypoglycemic Agents: Sulfonylureas01:17

Oral Hypoglycemic Agents: Sulfonylureas

Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...
