Cardiovascular Manifestations Documented in Patients with Lyme Disease: Clinical Presentation, Management Strategies, and Outcomes.
Review in Infectious disease reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesLyme disease is a tick-borne zoonosis caused by
methodsA narrative literature review was performed using PubMed, MEDLINE, and Google Scholar. Articles published between January 2000 and July 2025 in English or Spanish were screened. Eligible studies included original research articles, systematic and narrative reviews, case series, and case reports describing confirmed Lyme disease with cardiovascular involvement. A total of 30 studies were included. The available evidence was predominantly based on case reports and small case series, with considerable heterogeneity in study design, patient populations, and reported outcomes. Data on clinical manifestations, diagnostic methods, treatment strategies, and outcomes were extracted and synthesized.
resultsAtrioventricular conduction disturbances were the most frequently reported cardiovascular manifestation, ranging from first-degree block to complete heart block, often presenting abruptly with syncope or bradycardia. Other reported manifestations included atrial and ventricular arrhythmias, myocarditis, pericarditis, myopericarditis, valvular endocarditis, aortitis, and vasculitis. Diagnosis relied on a combination of clinical suspicion, epidemiologic exposure, serologic testing, electrocardiographic monitoring, and cardiac imaging. Most patients were treated with antimicrobial therapy, commonly intravenous ceftriaxone followed by oral doxycycline, with temporary pacemaker support required in selected cases. Overall, clinical outcomes were favorable when treatment was initiated promptly.
conclusionsCardiovascular involvement in Lyme disease, although infrequent, encompasses a broad clinical spectrum with potentially serious consequences. Early recognition, appropriate diagnostic evaluation, and timely antimicrobial therapy are essential to ensure reversibility of cardiac manifestations and favorable outcomes. However, the available evidence is limited by heterogeneity and the predominance of low-level-evidence studies.
