Patients with moderate aortic stenosis (AS) and elevated brain natriuretic peptide (BNP) levels face a worse prognosis. This condition significantly increases hospitalization and mortality risks, necessitating close monitoring.
Area of Science:
- Cardiology
- Cardiovascular Medicine
- Clinical Cardiology
Background:
- Moderate aortic stenosis (AS) presents a prognosis similar to severe AS.
- Elevated brain natriuretic peptide (BNP) levels indicate heart failure.
- The clinical course of moderate AS with heart failure signs is not well-defined.
Purpose of the Study:
- To investigate the clinical outcomes of patients with moderate AS and elevated BNP.
- To compare the prognosis of moderate AS with concomitant heart failure to controls.
Main Methods:
- Retrospective cohort study of 332 patients with elevated BNP.
- Comparison of 165 patients with moderate AS against 167 controls (none-mild AS).
- Median follow-up of 3.85 years, primary outcome: all-cause hospitalizations and mortality.
Main Results:
- Moderate AS with elevated BNP showed significantly higher rates of hospitalization and mortality.
- Moderate AS independently predicted increased all-cause hospitalizations (IRR 1.45).
- Higher hospitalization rates were observed in both heart failure with reduced and preserved ejection fraction.
Conclusions:
- Moderate AS combined with elevated BNP indicates a significantly worse prognosis.
- Patients with moderate AS and elevated BNP require vigilant clinical follow-up.
