Teacher: Now, understand the problem? Solve this instance: Question: Does serial bedside B-type natriuretic peptide strongly predict prognosis in acute coronary syndrome independent of echocardiographic abnormalities?
Answer: In ACS, bedside BNP levels predict CV events at 10 months, independent of many echocardiographic abnormalities including LVH. Furthermore, our study suggests that an additional 7 weeks post ACS BNP enhances risk stratification over and above a one-off high BNP at baseline.

yes
