Case 1 A 68-year-old man with a history of hypertension presented to the emergency department for evaluation of new-onset weakness and diaphoresis. He denied chest pain. He had no other coronary disease risk factors. Laboratory examination was normal except for leukocytosis (WBC = 22,000). He left against medical advice but returned 2 days later for persistent symptoms. Exercise SPECT MPI was requested. Baseline ECG The baseline ECG shows normal sinus rhythm with slightly increased QRS voltage consistent with left ventricular hypertrophy. Exercise Parameters He exercised on a Bruce protocol for 6:32 minutes, achieving an estimated workload of 7.7 METs. The peak exercise heart rate was 146 beats/min (96% of maximum age-predicted heart rate). No chest pain was reported, and the blood pressure response to exercise was normal. Peak Exercise ECG The peak exercise ECG demonstrated sinus tachycardia with 4 mm of downsloping ST-segment depression suggestive of ischemia. Raw Planar Images The postexercise (above) and resting (below) raw images are shown. Image quality appears adequate. Short-Axis Tomograms Only gold members can continue reading.
