Background: Chronic kidney disease (CKD) is associated with increased cardiovascular morbidity and mortality, even at early stages. Postmenopausal women represent a particularly vulnerable population due to estrogen deficiency, which promotes adverse cardiovascular remodeling. However, data specifically characterizing the cardiac phenotype of hypertensive postmenopausal women with mild-to-moderate CKD remain limited.
Methods: We conducted a prospective observational cohort study including 413 hypertensive postmenopausal women consecutively referred to a tertiary center between 2019 and 2022. Participants were stratified into a CKD group with stage 3 CKD (estimated glomerular filtration rate of 30–59 mL/min/1.73 m
2; n = 213) and a control group without CKD (n = 200). All subjects underwent comprehensive clinical evaluation, laboratory testing, and standardized transthoracic echocardiography. The prevalence of left ventricular hypertrophy (LVH), left ventricular diastolic dysfunction (LVDD), and chronic coronary syndromes (CCS) was assessed. Multivariable logistic regression analyses were performed to evaluate independent associations between CKD and cardiovascular abnormalities.
Results: Compared with controls, women with CKD showed a significantly higher prevalence of LVH (46.7% vs. 21.5%), LVDD (55.8% vs. 36.0%), and CCS (15.5% vs. 7.5%) (all
p < 0.01). The coexistence of LVH and LVDD identified a high-risk cardiac phenotype that was markedly more frequent in the CKD group (41.3% vs. 12.5%). After adjustment for age, body mass index, blood pressure, duration of hypertension, smoking status, and antihypertensive therapy, stage 3 CKD remained independently associated with LVH, LVDD, and CCS.
Conclusions: In hypertensive postmenopausal women, mild-to-moderate CKD is associated with a substantial burden of cardiac structural and functional abnormalities exceeding that attributable to hypertension alone, supporting early cardiovascular screening and an integrated cardiorenal approach.
