Aim: To explore the association of hyperhomocysteinaemia (HHcy) and diabetes synergies with cardiovascular events in the adult population of northern China. Methods: Data were collected from the Asymptomatic Polyvascular Abnomalities Community study for 2010 to 2019. Serum homocysteine (Hcy) levels were determined by enzyme-linked immunosorbent assay. The participants were categorized into four groups based on their Hcy levels and diabetes status: non-diabetes/non-HHcy, non-diabetes/HHcy, diabetes/non-HHcy and diabetes/HHcy. The composite endpoint consisted of the occurrence of first-ever stroke, myocardial infraction (MI) or all-cause mortality. Cox regression analyses were performed to evaluate the associations of diabetes and HHcy with cardiovascular disease (CVD) events. Results: In total, 5278 participants were eligible (average age 55.1 years, 60% male). Over a follow-up of 9.1 years, 618 events were identified, 202 stroke, 52 MI and 406 all-cause deaths. Compared with the non-diabetes/non-HHcy group, hazard ratios with 95% confidence intervals in the diabetes/HHcy group for stroke, MI, major adverse cardiovascular event (MACE), all-cause death and composite endpoint were 1.85 (1.12-3.04), 1.33 (0.42-4.23), 1.78 (1.13-2.80), 2.24 (1.56-3.23) and 1.97 (1.47-2.65), respectively. Significant interactions between HHcy and diabetes status were found for stroke, MI and MACE (P for interaction = .002, .027 and .044, respectively). In addition, the association of diabetes/HHcy with stroke was modified by age (< 60 and >= 60 years; P for interaction = .016). Conclusions: The findings highlight the synergistic impact of diabetes and HHcy on CVD. Joint assessments of diabetes and Hcy levels should be emphasized for risk stratification and primary prevention of CVD. |
