Background Major adverse cardiovascular events (MACEs) in patients with or without cardiovascular disease (CVD) are greatly affected by various factors associated with metabolism and inflammation. Objective To determine which clinical parameters at treatment are associated with the development of 2-year and 5-year MACEs in high-risk patients with CVD who have undergone drug-eluting stent (DES) implantation. Method The present study involved a total of 432 patients who underwent percutaneous coronary intervention with DES. Variables representing the average and absolute amount of change in clinical parameters over the 12-month follow-up were assessed for association with 2-year and 5-year development of MACE. The study population was divided into quartiles for the variable showing the highest correlation to MACE development. Estimated incidence of 2-year and 5-year MACEs for each of the quartiles was determined by survival curve analysis, and subgroup analysis was performed for patients with diabetes and statin users. Results Absolute change in fasting plasma glucose (FPG) over 12 months showed the highest correlation with 2-year and 5-year MACE development. The estimated incidence of MACE increased with increasing quartiles for absolute change in FPG. The association between absolute change in FPG and MACE development exhibited a stronger relationship for the specific subgroups of patients with diabetes and statin users. Increases and decreases in FPG had a comparable contribution to MACE development. Conclusion A greater absolute change in FPG over 12 months post-PCI is an independent risk factor for 2-year and 5-year MACE development in DES-implanted patients, especially in the diabetes and statin users.
