Peripartum cardiomyopathy (PPCM) is a rare and potentially life-threatening disease associated with pregnancy. There are limited data regarding the outcome of PPCM and its predictive factors in sub-Saharan African patients. We prospectively conducted a double-center (cardiology unit of the department of medicine, Regional Hospital Center of Tenkodogo, Burkina Faso and the department of cardiology of the National Referral Teaching Hospital of N'Djamena, Chad) cohort study in patients with PPCM. Patients were consecutively enrolled from January 2015 to December 2017. Outcomes of interest were left ventricular recovery and poor outcome at one year. Ninety-four patients enrolled with a median age of 28 years. At one-year follow-up, 40.5% of them recovered their left ventricular function. Cox multiple regression analysis revealed that higher left ventricle ejection fraction (LVEF), lower natremia and use of betablockers were baseline variables predicting this end-point. Of the entire study population, 26.60% exhibited the composite end-point of death (n=15) or remaining in New York Heart Association (NYHA) class III-IV or LVEF < 35%. Predictors of poor outcome were lower LVEF at baseline, hyponatremia and use of digoxin. The current cohort study demonstrated that PPCM in sub-Saharan Africa is associated with limited myocardial recovery and significant rate of poor outcome at one year. Therefore, additional studies are needed to better address the disease. [ABSTRACT FROM AUTHOR]

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., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.
