Role of Exercise Tolerance Test (ETT) and Gated Single Photon Emission Computed Tomography-Myocardial Perfusion Imaging (SPECT-MPI) in Predicting Severity of Ischemia in Patients with Chest Pain.

This was an observational study carried out in the department of cardiology. Bangabandhu Shikh Mujib Medical University (BSMMU), Dhaka in collaboration with Institute of Nuclear Medicine (INM), Shabag, Dhaka during the period October 2002-March 2003. A total of 54 patients presenting with Canadian Cardiovascular Society (CCS) class I-II severity of chest pain with mean.1:SD age 49.88.1:8.44 yrs and having male to female ratio 5.75: 1 were included in the study. The main objective of the study was to predict severity of myocardial ischemia by Exercise Tolerance Test (ETT) determined by Duke Treadmill Score (DTS) and by perfusion pattern observed following Single-Photon Emission Computed Tomography myocardial perfusion imaging (SPECT -MPI).
