Coronary artery bypass surgery in patients with low EuroSCORE preoperative risk

Abstract

<jats:title>Abstract</jats:title><jats:p>Patients with EuroSCORE &lt;2 are usually considered to have a low surgical risk and the lowest mortality. In our study preoperative factors in a group of 250 consecutive low-risk patients (EuroSCORE&lt;2), who underwent first isolated coronary artery by-pass surgery during 1999 and 2000., were analyzed. Cumulative follow-up period was 1178.48 patient-years and the primary clinical outcome was all-cause mortality. Patients’ average age was 59.2±7.5 yr. The following preoperative risk factors of increased 5-year mortality were identified: older age (P&lt;0.001), smoking, prior non-recent myocardial infarction and reinfarction, anteroseptal localization of myocardial infarction (P&lt;0.001), poor ejection fraction&lt;=35% (P&lt;0.001), dilatative cardiomyopathy (P&lt;0.001), wall motion systolic index 〉2 (P&lt;0.001), left atrial dilatation (P&lt;0.001), mitral regurgitation more than 2+ (P&lt;0.001), presence of left main disease, triple vessel coronary artery disease (P&lt;0.001), absence of collaterals (P&lt;0.001) and presence of more than 3 distal anastomoses. Through the present study it has been shown that it is possible to identify a subgroup of patients with low operative mortality and excellent 5-year survival after surgical treatment for coronary artery bypass surgery using preoperative clinical, echocardiographic, coronarographic and intraoperative data, even in difficult conditions of the civil war in the region.</jats:p>

Effect of left ventricular hypertrophy on the outcome of coronary artery bypass grafting

“…In contrast to our study, Zdravkovic et al, 18 analysed the preoperative risk factors in low risk patients exhibiting a EuroSCORE less than 2. Although recognizing smoking, old age, old myocardial infarction and poor ejection fraction, as major risk factors for increasing 5 year mortality, yet LVH was determined as non-significant in predicting mortality.…”
