RESUMO
Malaria, one of the major global public health events, is a leading cause of mortality and morbidity among children and adults in tropical and subtropical regions(mainly in sub-Saharan Africa), threatening human health. It is well known that malaria can cause various complications including anemia, blackwater fever, cerebral malaria, and kidney damage. Conventionally, cardiac involvement has not been listed as a common reason affecting morbidity and mortality of malaria, which may be related to ignored cases or insufficient diagnosis. However, the serious clinical consequences such as acute coronary syndrome, heart failure, and malignant arrhythmia caused by malaria have aroused great concern. At present, antimalarials are commonly used for treating malaria in clinical practice. However, inappropriate medication can increase the risk of cardiovascular diseases and cause severe consequences. This review summarized the research advances in the cardiovascular complications including acute myocardial infarction, arrhythmia, hypertension, heart failure, and myocarditis in malaria. The possible mechanisms of cardiovascular diseases caused by malaria were systematically expounded from the hypotheses of cell adhesion, inflammation and cytokines, myocardial apoptosis induced by plasmodium toxin, cardiac injury secondary to acute renal failure, and thrombosis. Furthermore, the effects of quinolines, nucleoprotein synthesis inhibitors, and artemisinin and its derivatives on cardiac structure and function were summarized. Compared with the cardiac toxicity of quinolines in antimalarial therapy, the adverse effects of artemisinin-derived drugs on heart have not been reported in clinical studies. More importantly, the artemisinin-derived drugs demonstrate favorable application prospects in the prevention and treatment of cardiovascular diseases, and are expected to play a role in the treatment of malaria patients with cardiovascular diseases. This review provides reference for the prevention and treatment of malaria-related cardiovascular complications as well as the safe application of antimalarials.

Corona virus disease 2019(COVID-19) has brought untold human sufferings and economic tragedy worldwide. It causes acute myocardial injury and chronic damage of cardiovascular system, which has attracted much attention from researchers. For the immediate strategy for COVID-19, "drug repurposing" is a new opportunity for developing drugs to fight COVID-19. Artemisinin and its derivatives have a wide range of pharmacological activities. Recent studies have shown that artemisinin has clear cardiovascular protective effects. This paper summarizes the research progress on the pathogenesis the pathogenesis of COVID-19 in cardiovascular damage by 2019 novel coronavirus(2019-nCoV) virus from myocardial cell injury directly by 2019-nCoV virus,viral ligands competitively bind to ACE2 and then reduce the protective effect of ACE2 on cardiovascular disease, "cytokine storm" related myocardial damage, arrhythmia and sudden cardiac death induced by the infection and stress, myocardial injury by hypoxemia, heart damage side effects from COVID-19 drugs and summarizing the cardiovascular protective effects of artemisinin and its derivatives have activities of anti-arrhythmia, anti-myocardial ischemia, anti-atherosclerosis and plaque stabilization. Then analyzed the possible multi-pathway intervention effects of artemisinin-based drugs on multiple complications of COVID-19 based on its specific immunomodulatory effects, protective effects of tissue and organ damage and broad-spectrum antiviral effect, to provide clues for the treatment of cardiovascular complications of COVID-19, and give a new basis for the therapy of COVID-19 through "drug repurposing".
