WASHINGTON (Feb 22, 2021) -

Developing early detection strategies and therapeutic options for cardiovascular complications from malaria can offer important clinical tools to health professionals treating patients with the disease, according to a state-of-the-art review published in the Journal of the American College of Cardiology.

Malaria, considered a tropical disease, is prevalent in the regions of Asia, Oceania, South America, Central America and Africa, where the highest mortality occurs. Malaria is caused by specific parasites and if transmitted by infected female Anopheles mosquitoes, can result in life-threatening complications. In 2018, malaria accounted for around 400,000 deaths worldwide. Although cardiac involvement has not been included as a frequent cause of morbidity and mortality from malaria, cardiovascular complications may be unrecognized and underreported due to lack of diagnostic strategies or overlap with other fatal events. Cardiovascular complications from malaria include myocarditis, pericarditis, pericardial effusion, ischemic disease and heart failure.

As part of the “Neglected Tropical Diseases and Other Infectious Diseases Affecting the Heart” (the NET-Heart Project), authors of this paper looked to review the available evidence of cardiovascular involvement in neglected tropical diseases and other infectious diseases. Analyzing 28 literature documents, they found that myocarditis is the most common cardiovascular complication of malaria. Data showed that the effects of myocarditis are often reversible by treating it with general anti-malarial drugs. However, the authors find it important to note that anti-malarial treatment regimens can have fatal cardiac side effects.

According to the authors, studies demonstrated that late detection of malaria could be frequent and deadly. The authors highlight that early detection of cardiovascular complications from malaria is critical to improve patient outcomes. They suggest strategies such as cardiac monitoring through electrocardiograms, blood testing and understanding physical symptoms for effective treatment of malaria.
