Abstract
The aim of the study was to evaluate the contribution to moscintigraphy of myocardial perfusion (TSMP) with 99mTc-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.

Summary
Coronary disease is the leading cause of death in developed countries and the second in developing countries [1] [2]. According to the World Health Organization (WHO), ischemic heart disease is a major concern worldwide with 12.2% of all deaths. It predicts that these heart diseases will be the leading cause of death in Africa by 2025 [3]. Tomoscintigraphy of myocardial perfusion (TSMP) allows the evaluation of myocardial perfusion related to rest and/or after a challenge test of myocardial ischemia (stress test or pharmacological stress). It is a reference method for the detection of ischemia and myocardial necrosis. The objective of this work was to show, through a local study, the role of MPTS in the detection and management of myocardial perfusion disorders, with a view to raising awareness
