Due to the potential underreporting of CV complications from malaria infections, consistent monitoring and management of CV complications can be unsatisfied areas of care, researchers reported.

Malaria was responsible for 400,000 deaths worldwide in 2018, according to a review published in the Journal of the American College of Cardiology, and while resume involvement has not often been attributed to infectious mortality, complications may be due to a lack of diagnostic tests or not being detected and underreported from overlap with other fatal ones Events.

“Malaria remains a serious health problem in endemic regions. Heart involvement appears to be rare due to the low incidence of reports. However, studies have shown that late detection can be potentially fatal and common. Early detection of CV tradeoffs is critical to improving prognosis, ”wrote Shyla Gupta, a student at Queen’s University’s Kingston Health Sciences Center in Kingston, Ontario, Canada and colleagues.

For this analysis, the researchers evaluated 28 documents to assess the involvement of the life course in malaria mortality and to report methods of monitoring and treating the heart.

CV Complications in Malaria

According to the review, reported CV complications include myocarditis, pericarditis, pericardial effusion, ischemic disease, and HF.

In addition, high serum levels of parasitemia, immunocompromised conditions, poor diet, and chronic heart problems can increase the severity of CV complications, the researchers wrote.

The researchers reported three possible pathophysiological causes of CV complications in malaria infections: an imbalanced proinflammatory cytokine response, endothelial dysfunction, and / or the sequestration of infected red blood cells in cardiac capillaries, causing obstruction of blood flow and ischemic injury.

According to the review, once the malaria infection is treated, the heart symptoms will subside. Therefore, there are no specific treatments for CV complications other than hemodynamic support when needed.

“The systemic stress of severe malaria infection is believed to affect overall heart function as well as other common complications such as severe anemia and kidney disease,” the researchers wrote. “In addition, some anti-malarial drugs have been reported to cause cardiotoxicity and present as CV complications during recovery.”

Complications in Malaria Treatment

Complicated malaria is treated with IV quinidine and replaced with sulfadoxine when serum parasitaemia decreases and symptoms disappear. However, polymorphic ventricular tachycardia is a known life-threatening complication of quinines. The researchers reported that other CV side effects include angina, hypotension, circulatory failure, and cardiac arrest. Quinidine can also cause prolonged QT syndrome in high-risk patients such as children with severe anemia, Gupta and colleagues wrote.

In addition, mefloquine, another therapy for malaria, may occasionally cause sinus bradycardia and long QT syndrome, according to the researchers.

“Standardized tests such as EKGs should be considered to detect and prevent a CV compromise early on,” the researchers wrote. “Patients diagnosed with malaria should be carefully monitored, especially if there are clinical findings of heart failure. Both serum parasitemia levels and cardiac biomarkers should be monitored, as they are important for determining CV involvement: Despite unspecific findings on physical examination, elevated levels of troponin T or N-terminal natriuretic peptide can be detected by the pro-B Type, suggesting a myocardial injury. ”

According to the review, previous routine EKGs, follow-up appointments, and early serum analyzes indicated that most CV involvements in malaria are fully reversible. However, in severe malaria, patients should be monitored promptly and routinely to prevent fatal progression.
