Аннотация
BACKGROUND: Metformin is the most widely used oral antihyperglycemic agent for patients with type 2 diabetes mellitus (T2DM). Despite the possible benefits of metformin on diabetes mellitus (DM) and heart failure (HF), acute or unstable HF remains a precaution for its use.
OBJECTIVE: The aim of the present prospective randomized controlled trial was to assess whether metformin treatment has beneficial effects on patients with T2DM with hypertension without overt HF.
METHODS: A total of 164 patients (92 males, 72 females; median age 66 years) were included in this study. Patients with T2DM with a history of hypertension were randomized 1:1 to treatment for 1 year with either metformin (metformin-treated group) or other hypoglycemic agents (control group). The primary endpoints were changes in brain natriuretic peptide (BNP) levels, left ventricular (LV) mass index, and indicators of LV diastolic function. We also evaluated changes in both clinical findings and blood laboratory examination data.
RESULTS: We observed no significant changes between baseline and 1-year post-treatment in LV mass index, BNP levels, or E/e' (early diastolic transmitral flow velocity/early diastolic mitral annular velocity; an indicator of LV diastolic function) in either the metformin-treated (n = 83) or the control (n = 81) groups. The metformin-treated group had a significant reduction of body mass index (BMI) and low-density lipoprotein cholesterol (LDL-C), but the control group did not. We determined that renal function, including serum creatinine and estimated glomerular filtration rate, deteriorated significantly in the control group but not in the metformin-treated group.
CONCLUSION: LV mass and diastolic function were not affected after 1 year of metformin treatment in patients with T2DM. However, we observed benefits in terms of reductions in both BMI and LDL-C levels and preservation of renal function.
