Impact of physical activity on presentation and prognosis of Brugada syndrome.
Article in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
INTRODUCTION AND
objectivesBrugada syndrome (BS) is a channelopathy associated with an increased risk of sudden cardiac death (SCD). Intense physical activity is a recognised trigger of life-threatening arrhythmias in long QT syndrome, catecholaminergic ventricular tachycardia syndrome and arrhythmogenic cardiomyopathy, but it is believed to be safe in BS. The objective of this study is to assess the impact of regular physical activity on the expression and prognosis of BS.
methods286 consecutive BS patients (aged 39.1±17.8 years old, 70.6% men) were included. Patients were classified according to the level of exercise and main discipline of sport they had practised.
results190 (66.4%) were sedentary, 27 (9.4%) practised light exercise, 59 (20.6%) moderate and 10 (5.3%) intense. Patients engaged in 'mixed or endurance' types of exercise were diagnosed earlier than sedentary ones (HR: 2.1; 95% CI: 1.5 to 2.9; p<0.001) and experienced syncope at a younger age (24.9±16.2 vs 37.4±18.2 years; p=0.04). Physical activity was associated with ECG sport-related changes like bradycardia (Δ 6 bpm) and a shorter QTc (Δ 21 ms) and also to a higher ST elevation in right precordial leads (Δ 0.5 mm). Physical activity was not a predictor of arrhythmic events or SCD.
conclusionsRegular physical activity was associated with a younger diagnosis and an earlier occurrence of syncopal episodes. BS patients engaged in 'mixed or endurance' sports have ECG changes associated with sport adaptation and higher ST segment elevation. Nevertheless, physical activity was not related to a higher arrhythmic risk in our cohort of patients with BS.
