    Streszczenie angielskie: Adrenomedullin (ADM) release is enhanced in pheochromocytoma, chronic heart failure (HF), hypertension and renal diseases. This study was designed to test the hypothesis that ADM secretion increases also in response to acute stimuli, such as static effort and to compare plasma ADM response to this stimulus in patients with chronic HF and healthy persons. Eight male HF patients (II/III class NYHA) and eight healthy subjects (C) performed two 3-min bouts of static handgrip at 30 p.c. of maximal voluntary contraction, alternately with each hand without any break between the bouts. At the end of both exercise bouts and in 5 min of the recovery period, plasma ADM and catecholamines were determined. In adition, heart rate, blood pressure, and stroke volume (SV) were measured. The baseline plasma ADM and noradrenaline levels were higher, whilst plasma adrenaline and SV were lower in HF patients than in C group. The 1 st exercise bout caused an increase in plasma ADM from 3.32 ń 0.57 to 4.98 ń 0.59 pmol 1-1 (p 0.01) in C and from 6.88 ń 0.58 to 7.80 ń 0.43 pmolú1-1 (p 0.02) in HF patients. The 2nd exercise bout did not produce further elevation in plasma ADM and during recovery the hormone concentration declined to pre-exercise or lower values. There were no differences between groups in exercise-induced increases in plasma ADM. Plasma ADM correleated with SV (r=-0.419) and with noradrenaline concentrations (r = 0.427) . It is concluded that static exercise causes the short-lasting in plasma ADM conccentration which is similar in healthy subjects and in patients with mild heart failure.
