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 (p2 production and MET (p2 production (p2 consumption in patients with DM2 is decreased to the same levels as in persons without DM2, who have IHD and HF. 2. Changes in oxygen-transport in persons with DM2 may serve as a marker of negative influence of the disease on cardiovascular system status. 3. Metoprolol improves parameters of cardio-respiratory system in patients with DM2.
