Which of the short term and long term compensatory mechanisms is least likely to decrease the symptoms of his heart failure?

Reassignment of cardiac pacemaking activities and suppression of the vagal nerve are not noted compensatory actions related to heart failure. Increased preload and sympathetic stimulation, increased levels of epinephrine and norepinephrine, and activation of the renin-angiotensin-aldosterone system and secretion of brain natriuretic peptide (BNP) are all noted compensatory mechanisms.
