[Contribution of the myocardial scintigraphy to the management of stable angina in Burkina Faso].

Objective: The objective of our work was to analyze the contribution of stress myocardial scintigraphy in the diagnosis of stable angina in the Cardiology Department of CHU YO.

Method: This was a retrospective study of 47 patients who received a stress myocardial scintigraphy from January 2012 to December 2013 for the diagnosis of stable angina. The scintigraphic sections were made after injection of the radiotracer (MibiTc99m) during the treadmill stress test.

Results: Myocardial scintigraphy accounted for 16% of all scintigraphy and stress myocardial scintigraphy for diagnosis of stable angina accounted for 64% of all myocardial scintigraphy. The average age of the patients was 47 ± 10 years. The sex ratio was 1.1. All patients had completed the treadmill stress test. The treadmill stress test was stopped for maximum effort in 42 cases (89%). The average duration of the effort was 12 minutes ± 2.4. Treadmill stress test was positive in three patients. Nineteen percent of patients had a pathologic myocardial scintigraphy. Scintigraphy was pathologic in all patients with a positive treadmill stress test.

Conclusion: Myocardial scintigraphy remains a sensitive examination for the diagnosis of stable angina. It helps to better stratify risk and adjust patient treatment.
