Dengue's Hidden Threat: Heart Problems Emerge

While dengue fever is typically characterized by high fever and a drop in platelet count, it can also lead to significant cardiac complications. These heart issues, though not always common, are recognized manifestations of the disease and can vary in severity.

The dengue virus may directly infect the heart muscle or provoke an intense immune response, causing inflammation known as myocarditis. This inflammation can impair the heart's pumping ability and disrupt its electrical pathways, potentially leading to abnormal heart rhythms.

ECG abnormalities such as sinus bradycardia and non-specific ST-T changes are frequently observed in dengue patients. The risk of cardiac complications escalates in cases of severe dengue, dengue hemorrhagic fever, or dengue shock syndrome due to extensive plasma leakage and circulatory instability.

Doctors emphasize that symptoms like breathlessness and hypotension in dengue patients may not solely stem from dehydration. Evaluating cardiac involvement is essential, particularly when conventional treatments show no significant improvement. While no specific antiviral drugs exist for dengue-induced myocarditis, management focuses on patient hydration, cardiac monitoring, and addressing other complications.

Fortunately, many patients with mild cardiac involvement experience a good recovery if the disease is diagnosed and treated early. This underscores the importance of a comprehensive approach to dengue management, recognizing its potential to affect multiple organ systems.
