BACKGROUND: The aim of this study to investigate the correlation of the peripheral concentrations of one representative estrogen, E2 estradiol, with various indicators reflecting different aspects of cardiac structures and functions.
METHODS: A total of 84 typical patients with hypertrophic cardiomyopathy (HCM) and 77 healthy subjects were enrolled. Venous blood samples were taken to test E2 estradiol contents. Echocardiographic imaging was performed to record various indices of cardiac structures and functions.
RESULTS: Concentrations of peripheral E2 estradiol were decreased in female HCM patients, compared to female normal controls; after medical treatment, peripheral E2 estradiol levels were elevated, nearly to normal levels. Peripheral E2 estradiol concentrations were negatively correlated with LAV (r2=0.5078, P<0.001), LAVI (r2=0.4257, P<0.001), E/A ratio (r2=0.4328, P=0.006) and E/Ea ratio (r2=0.4393, P<0.001) in female controls and patients.
CONCLUSIONS: Concentrations of peripheral E2 estradiol were negatively correlated with ventricular diastolic functions and this correlation was gender-dependent. Our study could provide clues to explore the molecular mechanisms of HCM, and clinic evidence for the diagnosis and prognostic management of HCM patients, as well as medical intervening for HCM.
