Multiple Choice

A 76-year-old man is brought to the emergency department after having 6 hours of shortness of breath and chest pain. His initial blood pressure is 102/72 mm Hg and pulse is 102/min. His oxygen saturation is 82% on 15 liters of oxygen via face mask. Bilateral rales are heard over the lower to middle lung fields. His initial ECG shows sinus tachycardia and a left bundle branch block. He is intubated and rushed to the cardiac catheterization lab.
He is found to have an occluded proximal left anterior descending artery and mild atherosclerosis involving the other coronary arteries. He has successful percutaneous revascularization with restoration of coronary flow. A pulmonary artery catheter is placed at the end of the procedure for hemodynamic monitoring and he is transferred to the coronary care unit. His current medications include aspirin, clopidogrel, intravenous unfractionated heparin, eptifibatide, furosemide, and propofol. Six hours after the procedure, his blood pressure is 78/48 mm Hg, and his pulse is 120/min and regular. His ECG shows sinus tachycardia and left bundle branch block pattern.
