Resultados de la cirugía coronaria sin circulación extracorpórea en el contexto del infarto agudo de miocardio

Abstract

Introduction and objectivesCurrent evidence shows that there is an inverse relationship between mortality and the time between surgery and the acute myocardial infarction. The objective of this study is to evaluate short and long term results of patients who underwent off-pump coronary artery bypass graft in acute myocardial infarction. MethodsA retrospective study was conducted on patients who underwent off-pump coronary artery bypass graft within 72hours of acute myocardial infarction. Short and long term results were examined, as well as mortality, revascularisation, and cardiac and cerebrovascular events. ResultsThe study included 26 patients between September 2003 and January 2016. The mean age was 62.5 (58.6-66.3) years and the patients were mostly males (89%). The pre-surgical troponin i peak was 35.6ng/ml (20.1-51.1). Left main artery disease was detected in 73% of patients. The Euroscore I mean was 24.5% (17.4-31.8). Mortality was 7.7%, with adjusted mortality risk of 0.31. Long term follow-up showed that cumulative survival at 5 and 10 years was 0.61 (0.34-0.80) and 0.48 (0.20-0.73), respectively. ConclusionsOff-pump Coronary artery bypass graft in acute myocardial infarction is a safe procedure with favourable results in the short-term and acceptable long-term results.
