Assessing a patient

          A 10-year-old patient has developed cardiomyopathy and biventricular heart failure due to radiation and chemotherapy treatments received for pulmonary neuroblastoma. He has tachycardia, has tachypnea, and becomes winded and exhausted with minimal exertion. How, if at all, would you expect the manifestations of this patient’s biventricular failure to differ from those in a patient with biventricular failure from a massive left anterior wall myocardial infarction (MI)? How, if at all, would treatments for this patient’s biventricular failure differ from those for a patient with biventricular failure from a massive left anterior wall MI?
