The investigators hypothesize that the level of perioperative natriuretic peptides is associated with in-hospital and long term major adverse cardiac events.
The purpose of the study is to measure levels of brain natriuretic peptides before and after urgent non-cardiac surgery and to evaluate their predictive value for adverse long-term outcome.

Occurence of Adverse Cardiac Events
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.
Time frame: postoperatively (index surgery) until a median follow-up of 34 months
