Background and objective: This was a cross-sectional study in which the values of sensitivity and specificity of myocardial perfusion study with (99)mTc-Tetrofosmina protocol in a day after stimulation with dipyridamole were determined in a population of women. We also assessed the relationship with coronary vascular territories, based on coronary angiography.
Patients and method: We studied retrospective medical records of 202 women with suspected ischemic heart disease tested on myocardial perfusion who also underwent coronary angiography.
Results: The values of sensitivity and specificity for the population were 87.16% and 81.48% respectively. For the coronary artery territory, the values of sensitivity and specificity for the DA artery were 68.75% and 77.78% respectively, while these were 60.0% and 81.51% for the Cx. Finally, the values for the CD were 69.88 and 72.27%, respectively.
Conclusions: The myocardial perfusion test stimulation/rest has a high diagnostic validity for the disease in women with suspected ischemic heart disease.
