Abstract
Patients suffering from chronic ischaemic cardiomyopathy and left ventricular ejection fraction (LVEF) lower than 30% represent a difficult and controversial population for surgical treatment. The aim of this study was to evaluate the effects of surgical treatment on the early and long-term outcome of these patients. The patient population comprised 50 patients with LVEF < 30% (78% male, mean age: 58.3 years, range: 42-75 years) who underwent surgical myocardial revascularisation during the period 1995-2000. Patients with left ventricular aneurysms or mitral valve insufficiency were excluded from the study. The following echocardiography parameters were evaluated as possible prognostic indicators: LVEF, fraction of shortening (FS), left ventricular systolic and diastolic diameters (LVEDD, LVESD) and volumes (LVEDV, LVESV), as well as their indexed values (LVESVI). Fifteen patients (30%) died during the follow-up, 2/50 intraoperatively (4%). The presence of diabetes mellitus, previous myocardial infarction, main left coronary artery disease, and three-vessel disease, correlated significantly with the surgical outcomes. The patient's age, family history, smoking habits, hypertension, hyperlipidaemia, history of stroke, peripheral...Continue Reading
