Abstract Background Cardiovascular diseases have continued to be the leading cause of death globally. In addition, some of the drugs used in the treatment of the diseases present some adverse effects which limit the usefulness of such drugs. Thus, there is a need for novel drugs whose side effect is either minimal or non-existent. The presence of bioactive compounds in Cola hispida leaf is of great significance in the treatment and management of cardiovascular conditions. This study investigated the cardio-protective potential against doxorubicin (Dox)-induced cardiac infarction in rats. Results Dox induction resulted to muscle fiber degeneration in Dox-treated rats hence revealed significant (p < 0.05) elevation in the serum level of cardio biomarker enzymes and lipid peroxidation profile while significant (p < 0.05) fall in cardiac enzymatic antioxidant levels were observed relative to the normal control. Pre-treatment with ethyl acetate fraction of Cola hispida leaf expressed cardio-protective potentials against Dox-induced cardiotoxicity by significantly (p < 0.05) lowering the levels of cardiac biomarker enzymes towards normal, building up the activities of subdued antioxidant enzymes and depleting its malondialdehyde level. Histopathology photomicrograph of the heart tissues expressed myxomatous degeneration but was ameliorated through the administration of the fraction. Conclusion In accordance with the findings from this study, the administration of ethyl acetate fraction of Cola hispida leaf is effective against Dox-induced redox imbalance due to its enriched antioxidant phytoconstituents.

ObjectiveWe sought to explore the prevalence and immediate clinical implications of acute myocardial injury in a cohort of patients with COVID-19 in a region of China where medical resources are less stressed than in Wuhan (the epicentre of the pandemic).MethodsWe prospectively assessed the medical records, laboratory results, chest CT images and use of medication in a cohort of patients presenting to two designated covid-19 treatment centres in Sichuan, China. Outcomes of interest included death, admission to an intensive care unit (ICU), need for mechanical ventilation, treatment with vasoactive agents and classification of disease severity. Acute myocardial injury was defined by a value of high-sensitivity troponin T (hs-TnT) greater than the normal upper limit.ResultsA total of 101 cases were enrolled from January to 10 March 2020 (average age 49 years, IQR 34–62 years). Acute myocardial injury was present in 15.8% of patients, nearly half of whom had a hs-TnT value fivefold greater than the normal upper limit. Patients with acute myocardial injury were older, with a higher prevalence of pre-existing cardiovascular disease and more likely to require ICU admission (62.5% vs 24.7%, p=0.003), mechanical ventilation (43.5% vs 4.7%, p<0.001) and treatment with vasoactive agents (31.2% vs 0%, p<0.001). Log hs-TnT was associated with disease severity (OR 6.63, 95% CI 2.24 to 19.65), and all of the three deaths occurred in patients with acute myocardial injury.ConclusionAcute myocardial injury is common in patients with COVID-19 and is associated with adverse prognosis.
