Insights
Men with Lyme carditis often experience atrioventricular blocks and arrhythmias. These cardiac issues are typically benign and reversible, especially in men, suggesting a favorable prognosis for Lyme carditis patients.
Area of Science:
- Cardiology
- Infectious Diseases
- Electrophysiology
Background:
- Lyme disease frequently causes cardiac complications, including electrophysiological abnormalities.
- Atrioventricular (AV) blocks and other arrhythmias are significant concerns in Lyme carditis.
Purpose of the Study:
- To investigate the association between AV blocks and other arrhythmias in patients diagnosed with Lyme carditis.
- To assess cardiovascular outcomes in relation to different types of arrhythmias in Lyme carditis.
Main Methods:
- A systematic review and meta-analysis of literature published between 1990 and 2023.
- Searched PubMed and Web of Science for Lyme carditis cases with concomitant arrhythmias using relevant MESH terms.
- Analyzed 110 cases, stratifying patients by AV blocks and other arrhythmias for cardiovascular outcome assessment.
Main Results:
- The majority of analyzed patients (77.3%) were male, with a mean age of 39.65 years.
- Men were more likely to develop first-degree AV blocks (OR = 1.36) and variable arrhythmias (OR = 1.31).
- AV blocks were often reversible (OR = 1.51), and ventricular/supraventricular arrhythmias showed instability and variability.
Conclusions:
- Men with Lyme carditis frequently present with various AV blocks.
- These AV blocks are generally benign, predictable, and have a stable clinical course.
- Further large-scale studies are needed to confirm these findings and associations.
Abstract:
Lyme disease often leads to cardiac injury and electrophysiological abnormalities. This study aimed to explore links between atrioventricular blocks and additional arrhythmias in Lyme carditis patients. This systematic review and meta-analysis of existing literature was performed from 1990 to 2023, and aimed to identify cases of Lyme carditis through serology or clinical diagnosis with concomitant arrhythmias. Pubmed and Web of Science were searched using appropriate MESH terms. Patients were divided into groups with atrioventricular blocks and other arrhythmias for cardiovascular (CV) outcome assessment. A total of 110 cases were analyzed. The majority (77.3%) were male, with mean age = 39.65 ± 14.80 years. Most patients presented within one week of symptom onset (30.9%). Men were more likely to have first-degree atrioventricular blocks (OR = 1.36 [95% CI 1.12-3.96], p = 0.01); these blocks tended to be reversible in nature (OR = 1.51 [95% CI 1.39-3.92], p = 0.01). Men exhibited a higher likelihood of experiencing variable arrhythmias (OR = 1.31 [95% CI 1.08-2.16], p < 0.001). Ventricular and supraventricular arrhythmias were more likely to exhibit instability (OR = 0.96 [95% CI 0.81-1.16] p = 0.01) and variability (OR = 1.99 [95% CI 0.47-8.31], p < 0.001). Men with Lyme carditis are likely to present with various atrioventricular blocks. These atrioventricular blocks are benign, and follow a predictable and stable clinical course. Further large-scale studies are warranted to confirm these associations.
