* No significant correlations were found between neprilysin levels and factors like age, body mass index, or natriuretic peptide levels, but individuals with lower neprilysin had higher instances of smoking, hypertension, and diastolic dysfunction.
* Over a median follow-up of 10.7 years, neprilysin levels were not linked to death or heart failure, suggesting more research is needed to understand its role in cardiometabolic conditions.
