BACKGROUND: Studies in Brugada syndrome (BrS) have mainly consisted of men.
OBJECTIVE: The purpose of this study was to describe the clinical characteristics and arrhythmic risk factors in BrS women.
METHODS: Consecutive BrS patients were enrolled from 1993 and followed prospectively.
RESULTS: Among 1613 patients, 494 were women (mean age 47 ± 16 years). Women were more frequently asymptomatic than men (423 [86%] vs 867 [77%], respectively; P = .001) and less frequently had a spontaneous ECG pattern (107 [22%] vs 398 [36%], respectively; P <.001). During median [25th, 75th percentile] follow-up of 57 [23, 118] vs 62 [22, 113] months (P = .65), arrhythmic events occurred in 12 women (2%) vs 79 men (7%) (P = .0005). Mean age at the first event was 48.6 ± 17.8 years for women vs 43 ± 14.2 years for men (P <.001). Gender was significantly related to cardiac events (hazard ratio [HR] 2.96; 95% confidence interval [CI] 1.6-5.4; P = .0005). In multivariate analysis, event predictors in women were index patient status (HR 10.15; 95% CI 1.7-61.4; P = .01), previous sudden cardiac death (HR 69.4; 95% CI 15-312.5; P <.0001), syncope (HR 6.8; 95% CI 1.4-34.5; P = .02), fragmented QRS (HR 20.2; 95% CI 1.8-228.9; P = .02), and QRS duration >120 ms (HR 4.7; 95% CI 1.2-19.5; P = .03).
CONCLUSION: Women represent a lower-risk group than men among individuals with BrS. In asymptomatic women, fragmented QRS and QRS >120 ms seem to be the only event predictors.
