Contribution of Myocardial Perfusion’s Tomoscintigraphy in the Management of Coronarian Disease in Senegal: About 42 Cases

Abstract

The aim of the study was to evaluate the contribution to moscintigraphy of myocardial perfusion (TSMP) with 99m Tc-sestamibi in the management of suspected or known coronary patients's population. It included 42 patients with an average age of 57.02 ± 9.77 years with extremes ranging from 36 to 77 years. The pre-test probability in 38 patients was high in 7 patients (18.42%), intermediate in 29 patients (76.31%) and low in 2 patients (5.26%). Patients with a high pre-test probability had a positive scintigraphy. Among the 26 patients who underwent transthoracic ultrasound (TTU), 10 with normal kinetics on trans-thoracic ultrasound (TTU) had positive scintigraphy. For 16 patients with TTU abnormalities, 6 had negative scintigraphy and 10 had positive scintigraphy. The TSMP was positive for 28 patients (66.66%). Among these patients, 16 had pure ischemia, 57.14% (16/28), 7 pure necrosis (25%), and 5 both necrosis and ischemia. Myocardial perfusion scintigraphy remains a very contributory consideration in the management of coronary disease. This is synchronized with the electrocardiogram (ECG) and is an important diagnostic and prognostic tool for coronary artery disease. It also provides a good indication of coronary angiography.
