|Abstract:||Aims/hypothesis: In nondiabetic individuals, low values of fasting plasma glucose (FPG) have been associated with an increased risk of cardiovascular events. Identification of the potential mechanisms behind this association could help to elucidate the relationship between glycaemia and cardiovascular disease. We aimed to determine the association between FPG and ventricular arrhythmias. Methods: FPG and other cardiometabolic risk factors were measured in a population-based cohort of 2,482 men without a known history of type 2 diabetes mellitus at baseline. Associations between FPG levels and incident cases of ventricular arrhythmias (ventricular tachycardia or fibrillation events ascertained using the National Hospital Discharge Register) were estimated using Cox regression analysis adjusted for potential confounders. Results: During a median follow-up of 23.3 (interquartile range 18.5–25.3) years, 74 (2.9%) incident events were recorded. In a multivariable analysis adjusted for age, systolic BP, smoking status, LDL- and HDL-cholesterol, and C-reactive protein, the HR for ventricular arrhythmia per 1 mmol/l higher baseline FPG was 0.58 (95% CI 0.34, 0.98); this estimate did not materially change after further adjustment for BMI, alcohol consumption, triacylglycerols and history of ischaemic heart disease (0.50 [95% CI 0.28, 0.89]). Conclusions/interpretation: In this nondiabetic male population, FPG was inversely associated with incident risk of ventricular arrhythmias. While our results could help clarify the relationship between low glucose levels and cardiovascular risk, further studies are required to confirm these findings in other populations.|
