High plasma aldosterone levels in patients with heart failure with preserved ejection fraction were independently associated with an increased risk of reduced glomerular filtration rate (OR 2.23) and severe albuminuria.
Cross-Sectional (n=158)
Is high plasma aldosterone associated with impaired renal function in patients with HFpEF?
In patients with HFpEF, secondary hyperaldosteronism is independently associated with an increased risk of impaired renal filtration and severe albuminuria.
Effect estimate: OR 2.23 (95% CI 1.24-9.63)
Absolute Event Rate: 72.9% vs 41.4%
p-value: p=0.003
Objective: To assess the relationship between plasma aldosterone levels and renal function in patients with heart failure with preserved ejection fraction (HFpEF). Materials and methods: A cross-sectional study included 158 patients with confirmed HFpEF. Patients with primary hyperaldosteronism, edema syndrome, end stage renal disease and taking mineralocorticoid receptor antagonists were excluded. Renal function was assessed by determining daily urinary albumin excretion (UAE) and calculating the glomerular filtration rate (GFR). Plasma aldosterone was measured by enzyme immunoassay. Results: The patients were divided into two groups: 99 patients had normal (40-160 pg/ml) aldosterone plasma level (nAld) and 59 patients had high (> 160 pg/ml) aldosterone level (hAld). hAld patients had significantly higher UAE (median 342 mg/day interquartile value 253; 453 versus 116 mg/day 32; 255, p 300 mg/day) albuminuria (odds ratio 2.23, 95% confidence interval 1.24-9.63). Conclusion: In HFpEF plasma aldosterone levels are closely related to renal function. Secondary hyperaldosteronism is associated with an increased risk of impaired renal filtration and severe albuminuria.
A. N. Shevelok (Thu,) conducted a cross-sectional in Heart failure with preserved ejection fraction (HFpEF) (n=158). High aldosterone level (> 160 pg/ml) vs. Normal aldosterone level (40-160 pg/ml) was evaluated on Decreased glomerular filtration rate (< 60 ml/min/1.73 m2) (OR 2.23, 95% CI 1.24-9.63, p=0.003). High plasma aldosterone levels in patients with heart failure with preserved ejection fraction were independently associated with an increased risk of reduced glomerular filtration rate (OR 2.23) and severe albuminuria.
