Diabetes Mellitus and Cardiovascular Disease Interactions

Diabetes mellitus and cardiovascular disease share a complex and bidirectional relationship in which chronic hyperglycaemia, insulin resistance and dyslipidaemia drive endothelial dysfunction and accelerate atherogenesis. Persistent high blood glucose leads to the formation of advanced glycation endproducts and reactive oxygen species, promoting inflammation within the vascular wall. Concurrent metabolic derangements amplify prothrombotic states, raising the risk of coronary artery disease, stroke and peripheral arterial disease. The duration of diabetes and the cumulative burden of multimorbidity further heighten mortality risk, while cardiovascular complications may in turn worsen glycaemic control. Multifactorial interventions targeting glycaemic indices, lipid profiles and blood pressure have demonstrated reductions in macrovascular events, yet residual risk remains substantial. Emerging approaches seek to refine risk stratification through immunological markers, metabolomic signatures and integrated models of cardiometabolic multimorbidity. Understanding the mechanistic interplay between metabolic dysfunction and vascular injury is essential to develop precision therapies and to mitigate the global burden of cardiovascular morbidity and mortality among people with diabetes.

Research from Nature Portfolio

Recent studies have quantified how the interplay of dyslipidaemia and low-grade inflammation in type 2 diabetes amplifies cardiovascular risk. Analyses in a large community cohort demonstrated that elevated triglycerides combined with pro-inflammatory cytokines such as tumour necrosis factor-α and interleukin-6 greatly increased the odds of myocardial infarction, while low levels of high-density lipoprotein cholesterol further magnified risk. In people with poorly controlled diabetes, high inflammatory markers independently predicted stroke. These findings underscore the value of combined lipid and inflammatory biomarkers for early detection of cardiovascular complications in diabetes.

The graph below shows the total number of articles in diabetes mellitus and cardiovascular disease interactions across all publications each year (not limited to Nature Index journals).

Technical terms

Advanced glycation endproducts: Molecules formed by non-enzymatic reactions between sugars and proteins or lipids, contributing to vascular damage.

Cytokines: Small signalling proteins released by cells that mediate inflammation and immune responses.

Insulin resistance: A state in which cells respond poorly to insulin, leading to impaired glucose uptake and elevated blood sugar.

Atherosclerosis: Accumulation of lipid‐laden plaques in the arterial wall, leading to vessel narrowing and ischaemic events.

Cardiometabolic multimorbidity: The coexistence of two or more metabolic or cardiovascular conditions, such as diabetes, heart disease and stroke.

Metabolomic biomarkers: Small‐molecule metabolites measured in biofluids that reflect physiological and pathological processes.

CD8+ T cells: A subset of T lymphocytes involved in targeted immune responses and cytotoxic activity.

Natural killer (NK) cells: Innate immune cells that recognise and destroy virus‐infected or malignant cells without prior sensitisation.
