NtBNP may refine risk stratification in severe AS; leaves open whether thresholds should guide intervention timing.
Do natriuretic peptides predict symptom-free survival and postoperative outcomes in patients with severe aortic stenosis?
In patients with severe aortic stenosis, natriuretic peptides (especially NtBNP) provide important prognostic information beyond clinical and echocardiographic evaluation, independently predicting symptom-free survival and postoperative outcomes.
Bergler‐Klein et al. (2004) studied this question.
