Objective: Cardioprotective effects and diminishing the in¬farct size in myocardium is well known features of beta bloc¬king agents. Previous studies showed that cardevilol has the same effects. The aim of our study was to compare the effects of carvedilol; an alpha-] and non "ive beta blocking agent and metoprolol, a "ive beta blocking agent, on insulin resistance and serum lipid levels in patients after myocardial infarction.
Study Design: Forty patients aged between 30 to 70 and BMI=25-30 kg!m2; who attended to our coronary intensive care unit within 24 hours of their angina and diagnosed as myocardial infarction with ST segment elevation are included in our study. Metoprolol 50mg/day (group I, n=20) or carvedilol 6.25mglday (group 2, n=20) was added to their combined therapy of acetylsalicilic acid, ramipril, isosorbide mononitrate and atorvastatin. Patients were followed up for 12 weeks. Baseline to week 4 and week 12 in fasting blood glucose, serum lipid profile, BMI, C-peptide, insulin and HO¬MA-IR levels were measured.
Results: In group 1, after 12 weeks of metoprolol therapy HOMA-IR, insulin and C-peptide levels were significantly higher than baseline (p=0.002, p=0.008 ve p=0.000, respectively) and week 4 (p=0.00I, p=0.64 ve p=0.014, respectively). In group 2, after 12 weeks of carvedilol therapy we observed the significant reduction of HOMA-IR, insulin and C- peptide (p=0.002, p=0.000, p=0.008, respectively).
Conclusion: The data of this study showed that in patients after myocardial infarction, an added carvedilol therapy provided an improvement in insulin resistance.
