Task: Answer Verification
Input (English): Question: Do troponin I and NT-proBNP ( N-terminal pro-brain natriuretic peptide ) predict 6-month mortality in frail older patients undergoing orthopedic surgery?
Answer: Troponin I and NT-proBNP were not predictors of 6-month mortality or cardiac events in an older frailer population of patients undergoing orthopedic surgery. These patients sustained substantial cardiac morbidity and mortality at 6 months after surgery. The control of symptoms, rather than prolongation of life with cardiological intervention, may be more appropriate for this patient group.
Output (English): no
