Insights
Lyme disease, a tick-borne illness, can rarely affect the heart, causing conduction disturbances. Prompt identification and treatment of Borrelia burgdorferi lead to a generally favorable prognosis for cardiac Lyme disease.
Area of Science:
- Infectious Diseases
- Cardiology
- Tick-borne Illnesses
Background:
- Lyme disease is a globally distributed tick-borne illness caused by Borrelia species.
- Clinical manifestations of Lyme disease vary, influenced by pathogen genetic diversity and epidemiology.
- Cardiac involvement, or Lyme carditis, is an uncommon but significant manifestation.
Purpose of the Study:
- To review the spectrum of cardiac manifestations associated with Lyme disease.
- To highlight the common cardiac abnormalities and potential complications.
- To emphasize the importance of timely diagnosis and treatment for prognosis.
Main Methods:
- Literature review of studies on Lyme disease and cardiac involvement.
- Analysis of reported cases of Lyme carditis.
- Synthesis of information on clinical presentation, diagnosis, and management.
Main Results:
- Atrioventricular block is the most frequent cardiac abnormality in Lyme carditis.
- Other reported cardiac issues include pericarditis, myocarditis, cardiomyopathy, and valvular disease linked to Borrelia burgdorferi.
- Unstable patients may necessitate temporary cardiac pacing.
Conclusions:
- Lyme carditis, though rare, presents with diverse cardiac abnormalities, primarily conduction disturbances.
- Effective treatment of the underlying Borrelia burgdorferi infection is crucial.
- With appropriate management, conduction disturbances in Lyme carditis generally have a good prognosis.
Abstract:
Lyme is a tick-borne disease. The genetic diversity of Borreliae its distribution worldwide and its epidemiology have been related to different clinical manifestations. Carditis is a rare manifestation of Lyme disease. The commonest abnormality is atrioventricular block of various degrees, though other rhythm abnormalities have been reported. Pericarditis, myocarditis, cardiomyopathy and degenerative valvular disease have been associated with B. burgdorferi. Temporary pacing might be required in unstable patients. The majority of the conduction disturbances have a benign prognosis, if the infectious agent is identified and treated appropriately.
