[Bypass aorto-coronarico. Correlazione tra dati clinici, emodinamici ed angiografici e risultato operatorio in 100 casi (author's transl)].
In 100 consecutive patients, subjected to myocardial revascularization by aorto-coronary saphenous vein bypass grafting with a standard technique, several clinical, hemodynamic and angiographic data were studied in correlation with the short-term prognosis. The operative mortality (6% on the whole) appeared to be strictly correlated with the degree of left ventricular impairment. Among the considered hemodynamic indices (LVEDP, CI, EDV, EF), EF was the most significant one: mortality was 0% if EF was normal, but raised to 15 and 40% respectively, when this was moderately or severely reduced. The operative risk was heavily aggravated if 4 or more indices of left ventricular impairment were present, mortality being 45% versus 1% in patients with abnormality of 3 or less parameters. The extension of coronary artery involvement proved to be a lesser prognostic factor than the degree of complements of the surgical revascularization. No correlation was found between the preoperative value of the hemodynamic parameters and the incidence of perioperative myocardial infarction (18% in the total series).
