Background: Left ventricular hypertrophy (LVH) is an important feature in patients with diabetes mellitus and increased the risk of cardiac events. The pathophysiology of LVH in diabetes mellitus remains unclear and is not fully explained by hyperglycemia and hypertension. Microvascular diseases, the most common and specific complications of diabetes mellitus, which may be involved in LVH. Therefore, we aimed to explore the association between diabetic microvascular diseases and LVH in patients with type 2 diabetes mellitus (T2DM).

Material and methods: In the cross-sectional study, we enrolled 2912 patients with T2DM, including 360 patients with LVH. Demographic data, medical history, anthropometric indices, laboratory examination, diabetic microvascular diseases and cardiac ultrasound index were collected. Correlation analysis and regression analysis were performed to analyze the relationship between diabetic microvascular diseases and LVH in whole population and in gender subgroup.

Result: Patients with LVH were older and had larger BMI, waist circumference and hip circumference. And a higher proportion of males had LVH compared with females. Patients with LVH had a larger proportion of hypertension, coronary heart disease, diabetic retinopathy (DR), and diabetic kidney disease (DKD). After adjusting potential confounding factors, patients with one or two microvascular diseases especially DR and DKD, had more possibility of LVH (OR = 1.287 and OR = 2.118 respectively). In gender subgroup analysis, microvascular diseases obviously increased the risk of LVH, especially in males. Moreover, the risk of LVH gradually increased with the number of diabetic microvascular diseases.

Conclusions: Diabetic microvascular diseases, especially DR and DKD, were positively and independently associated with LVH in T2DM. In addition, the risk of LVH obviously increased with the number of microvascular diseases in male.
