BACKGROUND Heart Rate Recovery (HRR) reflects the capacity of the cardiovascular system to reverse the vagal withdrawal caused by exercise. Scintigraphy with metaiodobenzylguanidine (I(123) MIBG) evaluates innervation and cardiac adrenergic activation. The association of these two methods is not well established. OBJECTIVE To evaluate the association between HRR and washout rate (WO) of I(123) MIBG in patients with heart failure (HF). METHODS Twenty-five patients with ejection fraction < 45… CONTINUE READING
