Summary
Obesity and diabetes are rising globally. This review explores how insulin resistance, a key factor in metabolic syndrome, links to endothelial dysfunction and atherosclerosis, impacting cardiovascular health.
Area of Science:
- Endocrinology and Metabolism
- Cardiovascular Science
- Public Health
Background:
- Rising global prevalence of obesity and diabetes mellitus, particularly in China and India.
- Insulin resistance is a central feature of metabolic syndrome and a precursor to diabetes mellitus.
- Endothelial dysfunction is an early indicator in atherosclerosis development.
Purpose of the Study:
- To review the intricate relationship between insulin resistance, endothelial function, and cardiovascular events.
- To highlight the significance of insulin resistance in the context of metabolic syndrome and atherosclerosis.
Main Methods:
- Literature review focusing on the interplay between metabolic and cardiovascular factors.
- Analysis of existing studies linking insulin resistance to endothelial dysfunction.
- Examination of the progression from insulin resistance to cardiovascular events.
Main Results:
- Insulin resistance is strongly associated with endothelial dysfunction.
- Endothelial dysfunction is a critical early step in the pathogenesis of atherosclerosis.
- These factors collectively contribute to increased cardiovascular event risk.
Conclusions:
- Understanding the link between insulin resistance and endothelial function is crucial for managing cardiovascular risk.
- Interventions targeting insulin resistance may mitigate atherosclerosis progression and reduce cardiovascular events.
- Further research is needed to address the epidemic of obesity and diabetes.

01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:26Diabetes Mellitus: Introduction
Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...
01:26Oral 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 glucose levels...
01:30Coronary Artery Disease I: Introduction
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
