BACKGROUND: Hidradenitis Suppurativa (HS) is a chronic, inflammatory skin disease, recently associated with metabolic syndrome, subclinical atherosclerosis and increased risk of cardiovascular disease.
OBJECTIVES: The aim of the study was to investigate the hitherto unknown electrocardiographic changes associated with HS, which recently have been associated with significant cardiovascular burden.
METHODS: Data were derived from the cross-sectional population study, The Danish General Population Study (GESUS). HS diagnosis was based on a validated self-reported questionnaire and 404 individuals met the HS diagnosis criteria and 19,001 controls without HS were identified in the population. Severity of HS was staged according to a modified Hurley score. The electrocardiographic parameters, Heart Rate (HR), PR-interval, QRS-duration, JTc-interval and QTc-interval, were obtained from 12-lead resting electrocardiograms. We investigated the difference in means by unpaired t-test or the analysis of variance (ANOVA) test.
RESULTS: Heart rate was significantly higher (mean difference: 2.3 bpm [1.2:3.4] p<0.01) when adjusting for age and gender but when multivariate adjusting, there was no significant difference (0.3 bpm [-0.7:1.4] p=0.52). Severe HS was significantly associated with increased heart rate across all models (2.9 bpm [0.7:5.1] p=0.01). Mean QRS-duration was significantly shorter in the mild HS group, but not in the moderate- and severe HS groups CONCLUSION: Mean resting heart rate in severe HS was significantly higher compared to controls. Given that resting heart rate is associated with increased risk of all-cause and cardiovascular mortality, and that HS patients have increased risk of cardiovascular events, this finding is potentially important, easily testable and intervenable.
