Similar Cardiovascular Outcomes Between Insulin Detemir and Insulin Glargine In Type 2 Diabetic Patients With Extremely Atherosclerotic Cardiovascular Disease Risks.

ABSTRACT

OBJECTIVE: The cardiovascular outcomes of insulin detemir in patients with type 2 diabetes mellitus (T2DM) after acute coronary syndrome (ACS) or acute ischemic stroke (AIS) are unclear. The aim of our real-life cohort study was to evaluate the cardiovascular outcomes of insulin detemir (IDet) versus insulin glargine (IGlar) in T2DM patients after ACS or AIS. METHODS: A retrospective cohort study was conducted between June 1, 2005, and December 31, 2013, utilizing the Taiwan National Health Insurance Research Database. A total of 3,129 ACS or AIS patients were eligible for the analysis. Clinical outcomes were evaluated by comparing 1,043 subjects receiving IDet with 2,086 propensity score-matched subjects who received IGlar. The primary composite outcome included cardiovascular (CV) death, nonfatal myocardial infarction (MI) and nonfatal stroke. RESULTS: The primary composite outcome occurred in 322 patients (30.9%) in the IDet group and 604 patients (29.0%) in the IGlar group (hazard ratio [HR], 1.12; 95% confidence interval [CI], 0.95 to 1.32) with a mean follow-up of 2.4 years. No significant differences were observed for CV death (HR, 1.09; 95% CI, 0.86 to 1.38), nonfatal MI (HR, 0.88; 95% CI, 0.66 to 1.19), and nonfatal stroke (HR, 1.15; 95% CI, 0.97 to 1.35). There were similar risks of all-cause mortality, hospitalization for heart failure and revascularization between the IDet group and the IGlar group (P = .647, .115, and .390 respectively). CONCLUSION: Compared with IGlar, in T2DM patients after ACS or AIS, IDet was not associated with increased risks of CV death, nonfatal MI, or nonfatal stroke.
