An 89-year-old-woman with well-controlled hypertension and dyslipidemia presents with acute severe substernal chest pain that started after news of the death of her best friend. In the ED, she is noted to have an initial ECG with ST elevation anteriorly. She is taken emergently for coronary angiogram, which reveals no significant coronary artery disease. Her left ventriculogram and echocardiogram are shown in Figures, respectively. Her echocardiogram is significant for a moderately reduced ejection fraction, an intracavitary gradient of 66 mmHg, mild mitral regurgitation, and systolic anterior motion of the mitral valve. Troponin T peaked at 3.36 μg/L (N < 0.04 μg/L). The patient is transferred to the coronary care unit for further management, where she develops sustained hypotension. What is the next best step for this patient?
A. Start dobutamine
B. Give intravenous fluids
C. Start norepinephrine
D. Place an intra-aortic balloon pump
