A 68-year-old woman, otherwise healthy, is admitted to the coronary care unit due to acute ischemic cardiomyopathy. No other significant past medical history. Her vital signs include: pulse 116/min, respiratory rate 21/min, temperature 37.4°C (99.3°F), and blood pressure 160/100 mm Hg. On physical examination, the patient is in distress. Cardiopulmonary exam is positive for bilateral pulmonary crackles at the lung bases, tachycardia, and jugular venous distension. Her laboratory findings are significant for a hemoglobin of 7.8 g/dL. She is initially treated with oxygen, antiplatelet therapy, nitroglycerin, and beta-blockers. In spite of these treatments, her angina does not subside. The patient is not a candidate for percutaneous coronary intervention, so she is being prepared for a coronary artery bypass graft. Which of the following would be the next, best step in management of this patient?
