Cardiac involvement in Chagas disease and African trypanosomiasis

Area of Science:

• Infectious Diseases
• Cardiology
• Parasitology

Background:

• Trypanosomiases are protozoan parasitic diseases with varied clinical outcomes.
• Trypanosoma cruzi causes Chagas disease, primarily affecting the heart and digestive system.
• Trypanosoma brucei causes African trypanosomiasis, impacting the central nervous system.

Purpose of the Study:

• To review the cardiac effects of trypanosomiases, focusing on Chagas disease.
• To highlight Chagas cardiomyopathy as a major cause of heart disease in Latin America.
• To inform cardiologists globally about the expanding prevalence of Chagas disease.

Main Methods:

• Review of existing literature on trypanosomiases and cardiac manifestations.
• Analysis of epidemiological data concerning Chagas disease.
• Discussion of the global dissemination of Trypanosoma cruzi infections.

Main Results:

• Chagas disease remains a leading cause of cardiomyopathy in endemic Latin American regions.
• International migration has led to a significant increase in Chagas disease cases outside traditional areas.
• Trypanosoma cruzi infections are now found globally, including Europe and the USA.

Conclusions:

• Cardiologists worldwide must recognize and manage Chagas cardiomyopathy.
• The global spread of Chagas disease requires increased clinical vigilance and awareness.
• Understanding the expanded epidemiology of Chagas disease is crucial for patient care.
