LV Volume / Pressure Overload
Primary Dilated Cardiomyopathy
Case history / Imaging data
SPECT myocardial perfusion studies were performed using Tc-99m-Sestamibi and Dobutamine. Images representing myocardial perfusion were obtained at rest and peak stress.

Stress protocol
  • Dobutamine
    • Duration of stress
  • 7 min 57 sec
    • Peak heart rate (basal --> peak)
  • 92 --> 100 (85%=131)
    		•
    Systolic BP (basal --> peak)
  • 130 --> 134 --> 92
    		•
    Double product (peak rate x BP)
  • 13,400
    		•
    Reason for termination
  • Typical chest pain
    • ECG findings
  • ST-T abnormality at rest
  • No additional changes
    		•
