Association between obesity and cardiac conduction defects
BackgroundLiterature on the association between high body mass index (BMI) and cardiac conduction defects (CCD) is scarce.MethodsThe cross-sectional association between obesity and CCD was examined in 455,790 participants (56.1 years; 55.9% females) from the United Kingdom (UK) Biobank. CCD was defi...

| description | BackgroundLiterature on the association between high body mass index (BMI) and cardiac conduction defects (CCD) is scarce.MethodsThe cross-sectional association between obesity and CCD was examined in 455,790 participants (56.1 years; 55.9% females) from the United Kingdom (UK) Biobank. CCD was defined by ICD codes as the presence of either atrioventricular block (AVB) or intraventricular block (IVB). Multivariable logistic regression models were used to assess the association between different levels of BMI and CCD.ResultsAbout 2.7% (n = 12,169) of the participants exhibited CCD. Each 1-SD increase in BMI (4.68 kg/m2) was associated with increased odds of CCD (OR (95% CI): 1.03 (1.01, 1.06). In subgroup analysis, this association was stronger in older participants (>65 vs. <65 years), men than women, and participants with diabetes (interaction p-value < 0.05 for all). In a stratified analysis by CCD subtypes, each 1-SD of BMI was associated with increased odds of AVB, but not IVB [OR (95% CI): 1.04 (1.01, 1.07), 0.97 (0.89, 1.05), respectively]. Compared to normal BMI (25–29.9 Kg/m2), participants with marked obesity, defined as BMI >40 Kg/m2, had 20% increased odds of CCD (OR (95% CI): 1.20 (1.04, 1.39). No significant association was observed with BMI between 30 and 39.9 Kg/m2.ConclusionsHigher BMI levels are associated with an increased risk of CCD, which is probably triggered by AVB, and the association is stronger in men, the elderly, and those with diabetes; further research is needed to examine whether weight management in obesity will be accompanied by a reduction in the risk of CCD. |
