Metabolic changers in oxygen transport in patients with diabetes mellitus type 2. Possibilities for correction

Abstract

Diabetes mellitus type 2 (DM2) - is an independent predictor of development of heart failure (HF). Spiroergometry - is a method for studying blood gas exchange parameters, commonly used for specification of HF. The purpose: 1. To study features of gas exchange at patients with DM2 without cardiovascular diseases in comparison with healthy control. 2. To estimate efficiency of metoprolol for correction of metabolic disturbances in patients with DM2. Materials and methods: 12 patients with DM2, aged 48,4±8, without history of cardiovascular diseases and 15 control subjects, aged 43,6±8 underwent cardio-pulmonary exercise test on treadmill, according to Bruce protocol. Exercise energy, VO2 peak, MET, VE max, VCO2 production were observed. Results: Patients with DM2 had a reduced exercise duration (p
