Background Dyslipidemia management situation in Chinese patients with high risk and very high risk has been demonstrated very low, despite the wide use of statins. The effects and safety of the combined treatment of ezetimibe (EZ) and statins in Chinese patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (T2DM) remain unknown. Methods Chinese Patients with ACS and T2DM were divided into the statins group (n = 40) and the combination group of EZ and statins (n = 44). In order to evaluate the clinical effects on lipids- lowering, systemic inflammation response and clinical safety, the follow-up of all patients was carried out at day 7th and 30th after treatment. Results The level of low-density lipoprotein cholesterol (LDL-C) in combination group and statins group was 1.87 ± 0.42 and 2.18 ± 0.58 mmol/L at day 7th, 1.51 ± 0.29 and 1.94 ± 0.49 mmol/L at day 30th, respectively. The control rates of LDL-C level in the combination group and the statins group were 77% and 45% at day 30th, respectively. There was no significant improvement on high-density lipoprotein cholesterol (HDL-C) level during follow-up. The triglyceride (TG) levels were significantly reduced in both groups, while no obvious difference was observed between two groups. No significant difference on serum high- sensitivity C-reactive protein (hs-CRP) level between two groups was observed. Moreover, we did not observe any significant correlation between serum lipids levels and serum hs-CRP level during follow-up. The liver dysfunction and muscle related side effects (MRSE), creatine kinase (CK) and myopathy were not observed in both groups. Conclusion Our study demonstrated that it is feasible to initiate combination therapy during acute phase for Chinese patients with ACS and T2DM, which can bring more significant effect on LDL-C-lowering and improve the control rate of LDL-C level with good safety.
