Natriuretic Peptides - Predictors of In-hospital and Long-term Major Adverse Cardiac Events After Emergency Surgery?
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Prospective Study to Evaluate the Predictive Value of Brain Natriuretic Peptides for Adverse Long-term Cardiac Outcome|
- Occurence of Adverse Cardiac Events [ Time Frame: postoperatively (index surgery) until a median follow-up of 34 months ]
Occurence of major adverse cardiac events (composite of nonfatal myocardial infarction, acute heart failure or death).
Non-fatal Myocardial infarction was defined as a typical increase and decrease of troponin together with evidence of myocardial ischemia with at least one of the following: symptoms of ischemia, ECG changes indicative of ischemia or new Q waves, or imaging evidence of new regional wall motion abnormality.
Acute heart failure was defined as clinical signs and symptoms of heart failure with echocardiographic evidence of cardiac dysfunction and clinical response to treatment directed towards heart failure.
- NT-ProBNP Preoperative [ Time Frame: 0-24 hours before induction of anesthesia ]NT-ProBNP was measured 0-24 hours before induction of anesthesia
- Association Between Preoperative NT-ProBNP and Occurence of Adverse Cardiac Events [ Time Frame: postoperatively (index surgery) until a median follow-up of 34 months ]Evaluation of the association between preoperative NT-ProBNP and occurence of adverse cardiac events
