Abstract:
Objective To investigate the characteristics of left ventricular hypertrophy in patients with primary aldosteron-ism(PA)accompanied by varying severity of obstructive sleep apnea(OSA),and to further identify potential factors contributing to ventricular hypertrophy in this population.Methods A retrospective analysis was performed on 308 patients with PA who received treatment at Kunming Medical University Affiliated Cardiovascular Hospital from January 2021 to June 2022.For com-parison,309 hospitalized patients diagnosed with essential hypertension(EH)during the same period were included as the control group.According to polysomnography findings,the patients were categorized into PA/EH with OSA group and PA/EH without OSA group.PA patients with OSA were further stratified into mild,moderate,and severe OSA subgroups based on the apnea-hypopnea index(AHI).Demographic characteristics,biochemical profiles,and echocardiographic parameters were compared across the groups.Results Compared to the EH groups with or without OSA,interventricular septal diastolic thickness(IVS-DT),left ventricular mass index(LVM),and left ventricular mass index(LVMI)was increased in PA with OSA group(all P<0.05).The body mass index(BMI)was increased in both the PA with OSA group and EH with OSA group compared to their counterparts without OSA(all P<0.05).Within the three subgroups of PA patients with OSA,left ventricular end-diastolic di-mension(LVEDD),IVSDT,left ventricular posterior wall diastolic thickness(LVPWDT),and LVM measurements were in-creased in severe OSA group compared to the mild OSA group(all P<0.05).Conclusion Aldosterone is an independent risk factor from OSA for left ventricular hypertrophy;In PA patients with OSA,cardiac impairment is severer in the moderate and severe OSA subgroups compared to those without OSA,and the severity of cardiac impairment escalates as OSA severity increa-ses.These findings highlight the necessity of screening for OSA in PA patients to stratify cardiac impairment risk and enable early therapeutic intervention.
