 A 48-year-old woman was admitted for progressive dyspnea after chemotherapy against breast cancer including adriamycin at a cumulative dose of 500mg/m2. Chest roentogenogram revealed severe pulmonary congestion with a plasma BNP of 1,796pg/ml and her left ventricular contraction was severely impaired with an ejection fraction of 20%. After her clinical condition of 'Wet & Cold' was relieved by using the intravenous injection of carperitide and catecholamines for 3 weeks, cautious incremental uptitration of valsartan and carvedilol led to our tapering off of the intravenous agents without the patient suffering re-exacerbated heart failure(HF). Symptomatic relief was obtained at NYHA class Ⅱ, with the negative troponin T and decreased BNP level of 88pg/ml, six months after the start of the therapy.

 Although it has been reported that therapeutic response to HF drugs is very poor with bad prognosis, adequate combined use of renin-angiotensin blockers and beta-blockers may lead to clinical improvement of HF status in adriamycin-induced cardiomyopathy.
