Insights
Diabetes mellitus significantly increases the risk of cardiovascular and cerebrovascular events. This review explores how diabetes-induced metabolic changes promote atherothrombotic disease, leading to heart attacks and strokes.
Area of Science:
- Cardiovascular Science
- Metabolic Disease Research
- Vascular Biology
Background:
- Diabetes mellitus is a metabolic disorder characterized by hyperglycemia.
- It is linked to chronic vascular complications, particularly macrovascular disease.
- Macrovascular disease in diabetes contributes significantly to mortality from myocardial infarction and stroke.
Purpose of the Study:
- To review the complex mechanisms underlying atherothrombotic disease in diabetes.
- To elucidate how the diabetic metabolic environment alters vascular and coagulation processes.
- To understand the pathogenesis of vascular disease in diabetic patients.
Main Methods:
- Review of existing literature on diabetes and vascular disease.
- Analysis of the interplay between metabolic dysregulation and atherothrombosis.
- Examination of factors including lipid metabolism, vascular responses, and coagulation/fibrinolysis.
Main Results:
- Diabetes mellitus alters lipid metabolism, vascular responses, and coagulation/fibrinolysis.
- The diabetic metabolic milieu promotes atheroma formation and platelet aggregation.
- These changes collectively increase the risk of atherothrombotic events.
Conclusions:
- The pathogenesis of macrovascular disease in diabetes is multifactorial.
- Diabetic metabolic derangements are central to the increased risk of heart attack and stroke.
- Understanding these mechanisms is crucial for managing vascular complications in diabetes.
Abstract:
Diabetes mellitus is characterized by fasting hyperglycaemia and the development of chronic vascular complications. While microvascular disease has been strongly related to glycaemic control, the major cause of mortality in diabetes is due to macrovascular disease affecting the cardiac and cerebrovascular circulations, which appear to have a more complex pathogenesis. Diabetes is associated with a 3-5-fold increase in death from myocardial infarction and similar figures pertain to stroke. The processes involved in atherothrombotic disease are complex and include variation in lipid metabolism, vascular responses, cell/cell interactions, and in the fluid and cellular phases of coagulation and fibrinolysis. The complex interactions between all of these processes are crucially altered by the metabolic milieu that characterizes diabetes mellitus, tipping the delicate balance towards atheroma formation, platelet aggregation and thrombus formation. This article will review these mechanisms and the effects of diabetes in the pathogenesis of vascular disease.
