Insights
Diabetes significantly elevates atherosclerosis risk, with postprandial hyperglycemia being a key driver beyond traditional factors. Understanding these diabetes-specific mechanisms is crucial for developing targeted therapies to prevent cardiovascular disease (CVD).
Area of Science:
- Endocrinology and Metabolism
- Cardiovascular Research
- Molecular Medicine
Background:
- Diabetes mellitus markedly increases the risk of atherosclerotic vascular disorders, including coronary, cerebrovascular, and peripheral artery disease.
- Cardiovascular disease (CVD) is a leading cause of disability and mortality in diabetic patients.
- While conventional risk factors contribute, they do not fully explain the exaggerated CVD risk in diabetes.
Purpose of the Study:
- To review the molecular mechanisms underlying accelerated atherosclerosis in diabetic patients.
- To emphasize the role of postprandial hyperglycemia as a specific diabetes-related risk factor.
- To discuss potential therapeutic strategies targeting CVD in diabetes.
Main Methods:
- Literature review focusing on molecular mechanisms of atherosclerosis in diabetes.
- Analysis of the contribution of postprandial hyperglycemia to cardiovascular complications.
- Exploration of therapeutic targets for CVD in diabetic populations.
Main Results:
- Accelerated atherosclerosis in diabetes involves specific mechanisms beyond traditional risk factors.
- Postprandial hyperglycemia plays a significant role in enhancing this accelerated process.
- Existing risk factors are insufficient to account for the full extent of macrovascular complications.
Conclusions:
- Specific diabetes-related factors, particularly postprandial hyperglycemia, are critical contributors to the excess CVD risk.
- Further research into these mechanisms is needed to develop effective, targeted therapies.
- Novel therapeutic strategies focusing on diabetes-specific pathways are essential for managing CVD in diabetic patients.
Abstract:
Diabetes is associated with a marked increase in the risk of atherosclerotic vascular disorders, including coronary, cerebrovascular and peripheral artery disease. Cardiovascular disease (CVD) could account for disabilities and high mortality rates in patients with diabetes. Conventional risk factors, including hyperlipidaemia, hypertension, smoking, obesity, lack of exercise and a positive family history, contribute similarly to macrovascular complications in type 2 diabetic patients and non-diabetic subjects. The levels of these factors in diabetic patients are certainly increased, but not enough to explain the exaggerated risk for macrovascular complications in diabetic population. Therefore, specific diabetes-related risk factors should be involved in the excess risk in diabetic patients. In this paper, we review the molecular mechanisms for accelerated atherosclerosis in diabetes, especially focusing on postprandial hyperglycaemia. We also discuss here the potential therapeutic strategy that specifically targets CVD in patients with diabetes.
