[The prognostic significance of heart rate variability during the type 2 dm developed with the ischemic heart disease and arterial hypertension].

In recent decades the special attention is given to the Heart Rate Variability (HRV) to assess the prognosis of the patients with cardiovascular diseases. There were studied 47 male with arterial hypertension and heart failure, by which the HRV was researched. In the group of patients with type 2 diabetes mellitus (DM), ischemic heart disease (IHD), arterial hypertension (AH) and heart failure (HF), the heart rate variability (HRV) has been considerably lowered in comparison with the group of patients at which the presence of DM was absent.

Coronary artery bypass grafting in patients with low ejection fraction.

Coronary artery bypass grafting (CABG) has been widely used for the treatment of patients with coronary artery disease. Patients with low ejection fraction (EF) are at a higher risk for postoperative complications and mortality. Our objective was to assess the effect of low EF on clinical outcomes of CABG.
