BACKGROUND AND AIMS: Subclinical cardiac disease, like abnormal left ventricular (LV) geometry or left atrial (LA) dilatation, is common in obesity. Less is known about sex differences in the prevalence and type of subclinical cardiac disease in obesity.
METHODS AND RESULTS: Clinical and echocardiographic data from 581 women and men without established cardiovascular disease and body mass index (BMI) > 27.0 kg/m2 participating in the FAT associated CardiOvasculaR dysfunction (FATCOR) study was analyzed. LA dilatation was recognized as LA volume indexed for height2 ≥16.5 ml/m2 in women and ≥18.5 ml/m2 in men, and abnormal LV geometry as LV hypertrophy and/or increased relative wall thickness. On average, the participants were 48 years old, 60% women and mean BMI was 32.1 kg/m2. Overall, the prevalence of subclinical cardiac disease was higher in women than men (77% vs. 62%, p < 0.001). Women had a higher prevalence of LA dilatation than men (74% vs. 56%, p < 0.001), while men had a higher prevalence of abnormal LV geometry (30% vs. 21%, p = 0.011). After adjusting for confounders in multivariable logistic regression analysis, female sex was associated with a 2-fold higher risk of subclinical cardiac disease, in particular LA dilatation (confidence interval [CI] 1.67-3.49, p < 0.001), while male sex was associated with a 2-fold higher risk of abnormal LV geometry (CI 1.30-3.01, p = 0.001).
CONCLUSION: The majority of overweight and obese participants in the FATCOR study had subclinical cardiac disease, which may contribute to the impaired prognosis observed in obesity. Women had a higher prevalence of subclinical cardiac disease than men.
