Core Tip

Core Tip: During the coronavirus disease 2019 (COVID-19) pandemic, western studies have shown the ineffectiveness and cardiotoxic effects of hydroxychloriquine and azithromycin (HCQ-AZI). In Africa, the heart toxicity of HCQ-AZI is little reported by cardiologists, and some African countries used these two molecules to treat COVID-19 patients. In the present study, we have evaluated the occurrence of prolongation of the QTc interval and torsade de pointes torsade in Congolese COVID-19 patients who received HCQ-AZI compared to doubase C, a herbal medicine with broad-spectrum antiviral activity.
