Arterial stiffness as a risk factor for cardiovascular events and all‐cause mortality in people with Type 2 diabetes

Diabetes is a common risk factor for cardiovascular disease. Coronary heart disease and left ventricular dysfunction are more common in diabetic patients than in non-diabetic patients, and diabetic patients benefit less from revascularisation procedures. This increased risk can only partly be explained by the adverse effects of diabetes on established risk factors; hence, a substantial part of the excess risk must be attributable to direct effects of hyperglycaemia and diabetes. In type 2 diabetes, hyperinsulinaemia, insulin resistance and hyperglycaemia have a number of potential adverse effects, including effects on endothelial function and coagulation. Risk factor modification has been shown to reduce the occurrence of cardiovascular events in patients with diabetes; indeed, diabetic patients appear to benefit more in absolute terms than non-diabetic patients. There is thus a strong case for intensive treatment of risk factors, including insulin resistance and hyperglycaemia, in patients with type 2 diabetes.

Objective: Mannose-binding lectin (MBL) is linked to risk of cardiovascular disease in diabetes, but the nature of the association is unclear. We investigated the association between MBL and risk of cardiovascular events (CVE) and all-cause mortality in type 2 diabetes. Research Design and Methods: In a cohort study of 7588 patients with type 2 diabetes, we measured serum MBL in 7305 and performed MBL expression genotyping in 3043. We grouped serum MBL and MBL expression genotypes into three categories: low, intermediate, and high. Outcomes were CVE (myocardial infarction, stroke, coronary revascularization, unstable angina, and cardiovascular death) and all-cause mortality. The association with outcomes was examined by spline and Cox regression analyses. Results: Serum MBL and CVE showed a U-shaped association. Compared to the intermediate serum MBL category, the adjusted hazard ratio (HR) for CVE was 1.82 (95% CI, 1.34 to 2.46) for the low-MBL category and 1.48 (95% CI, 1.14 to 1.92) for the high-MBL category. We found a similar U-shaped association for all-cause mortality, but with lower risk estimates. Compared to the intermediate MBL expression genotype, the adjusted HR for CVE was 1.40 (95% CI, 0.87 to 2.25) for the low-expression genotype and 1.44 (95% CI, 1.01 to 2.06) for the high-expression genotype. MBL expression genotype was not associated with all-cause mortality. Conclusions: Both serum MBL and MBL expression genotype showed a U-shaped association with CVE risk in individuals with type 2 diabetes. Our findings suggest that serum MBL is a risk factor for cardiovascular disease in this population.
