The aim is to study the interaction of natriuresis curves with 24-h blood pressure (BP) profile, as well as to study the effect of diuretic therapy on natriuresis changes and on the BP profile.Materials and methods. From the group of patients who participated in the study on the types of natriuretic curves we selected patients (n=56) with signs of deterioration of chronic heart failure (CHF) and who should be prescribed diuretic therapy. Patients received torasemide SR or IR. Results. It was demonstrated that type of natriuresis curves and blood pressure (BP) profile could be changed. Deterioration of natriuresis more oftener and earlier were observed in torasemide IR group compared with torasemide SR group of patients (p

Stimulation of endogenous opiate secretion worsens circulatory dysfunction in several forms of shock, in part by inhibiting sympathetic activity. To investigate whether endogenous opiates have a similar effect in chronic heart failure (HF), we measured beta-endorphin concentrations and hemodynamic responses to naloxone infusion (2 mg/kg bolus + 2 mg.kg-1 x h-1) in six control (C) dogs and eight dogs with low-output HF produced by 3 wk of rapid ventricular pacing. The dogs with HF exhibited reduced arterial blood pressure (C, 123 +/- 4 vs. HF, 85 +/- 7 mmHg; P < 0.01) and cardiac outputs (C, 179 +/- 14 vs. HF, 76 +/- 2 ml.min-1 x kg-1; P < 0.01) and elevated plasma norepinephrine concentrations (C, 99 +/- 12 vs. HF, 996 +/- 178 pg/ml; P < 0.01) but normal beta-endorphin concentrations (C, 30 +/- 11 vs. HF, 34 +/- 12 pg/ml; P = NS). Naloxone produced similar transitory increases in blood pressure (C, 14 +/- 5 vs. HF, 26 +/- 25%) and cardiac output (C, 37 +/- 13 vs. HF, 22 +/- 15%) in both groups (both P = NS). No significant changes in norepinephrine concentration or systemic vascular resistance were observed in either group. These findings suggest that beta-endorphin secretion does not exacerbate circulatory dysfunction in chronic heart failure.

Muscle Afferent

The roles of muscle afferent activity and central drive in controlling the compromised cardiovascular system of patients with mild chronic heart failure (CHF) during isometric exercise were examined. Blood pressure and heart rate responses were recorded in eight stable CHF patients (ejection fraction 20–40%; age 62±11 years) and in nine healthy age-matched controls during voluntary and electrically evoked isometric plantar flexion and subsequent post-exercise circulatory occlusion (PECO). During voluntary contraction, control subjects had a greater mean increase in systolic blood pressure than patients (42.4±19.2 and 23.0±10.9 mmHg respectively; P < 0.01), but this was not the case during PECO. During electrically evoked contraction, but not during PECO, the CHF group had smaller (P < 0.05) mean increases in both systolic and diastolic blood pressure than controls (13.0±5.3 compared with 25.4±14.0 mmHg and 7.6±3.0 compared with 12.9±7.2 mmHg respectively). Intra-group comparison between responses to voluntary and electrically evoked contractions revealed greater (P < 0.05) mean increases in systolic and diastolic blood pressure during the voluntary contraction in both the patients and the control subjects. These data suggest that muscle afferent drive to the pressor response from the triceps surae is low in this age group, both in control subjects and in CHF patients. Additionally, the patients may have a relatively desensitized muscle mechanoreceptor reflex.
