817 IDENTIFICATION OF ECHOCARDIOGRAPHIC FACTORS PREDICTING MACE AT 30 DAYS FROM NON CARDIAC SURGERY IN A PRE-HOSPITALIZATION COURSE


 
 
 200 million adults all over the world undergo noncardiac surgery each year, of which more over than 10 million develop MACE within 30 days of surgery. Cardiovascular complications represent the majority of the causes of mortality and morbidity (incidence from 0.5% to 30%), especially myocardial infarct and atrial fibrillation. Ecocardiographic patterns of increasing atrial size and reduction ejection fraction (EF) related to ischemic injury after surgery are related to the construction of a proarrhythmic substrate.
 
 
 
 The study carried out at the Campus Bio-medico Polyclinic recruits a population of 100 candidates for non-cardiac surgery at intermediate or elevated-risk and with cardiac disease or cardiovascular risk factors. These patients after clinical and 12-lead ECG examination have done echocardiographic study, with evaluation of Global ventricular longitudinal strain, left atrial volume, left ventricular ejection fraction, left ventricular filling volumes and aortic vessel diameters.
 
 
 
 Patients underwent a follow-up 30 days after surgery and it was shown that there is a important significance in relation to Global Longitudinal Strain (p = 0.01) in MACE patients and a modest significance in relation to the ejection fraction (p = 0.07) among MACE patients. Patients with atrial fibrillation (p = 0.10) and type 2 diabetes mellitus (p = 0.15) have a mild predisposition to MACE. Maiority of events were 30 day after surgery in patients with elevated risk.
 
 
 
 This study underlines the importance of careful preoperative selection and appropriate cardiological postoperative patient evaluation and the value of echocardiographic predictive factors of main perioperative cardiovascular events.
