- Abstract
Objective: To determine the diagnostic accuracy of Single Photon Emission Computed Tomography by taking Coronary Angiography as gold standard forthe detection of Coronary Artery Disease. Methodology: It is a cross-sectional study conducted at the Department of Cardiology, Chaudhry Pervaiz Elahi Institute of Cardiology, Multan from September 2013 to March 2014. Patients with age > 4 0 years belonging to either sex with at least one episode of chest pain lasting for > 3 0 minutes were included in the study. All patients underwent SPECT Scan and the findings of SPECT were confirmed by performing Coronary Angiography of every patient. Results: Out of 282 patients, 45.03%(n=127) were between 40-60 years and 54.97%(n=155) had >60 years of age, with mean age of 60.83±9.32 years. Males were 52.13%(n=147). Results of single photon emission computed tomography by taking coronary angiography as gold standard forthe detection of coronary artery disease showed 17.02%(n=48) were true positive, 2.48% (n=7) were false positive, 77.31% (n=218) were true negative and 3.19% (n=9) were false negative. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate was computed as 84.21%, 96.88%, 87.27%, 96.03% and 94.33% respectively. Conclusion: We concluded that Single Photon Emission Computed Tomography, by taking Coronary Angiography as gold standard forthe detection of Coronary Artery Disease, has a good diagnostic accuracy and can be used to curtail the financial burden of diagnosis.
