In our centre, during the last five years, emergency operations (within 6 hours) and urgent operations (within 72 hours) have represented 1/4 of all coronary surgery. 295 patients (pts) have been operated on since 1972: of these, 279 with simple revascularization, 5 with combined major surgery, and 11 as a consequence of mechanical complications of acute myocardial infarction. These last were all in cardiogenic shock: the overall 30-day mortality rate was 5.4% (3.6% in those pts with simple revascularization, 20% in those with combined major surgery, and 45.4% in pts with cardiogenic shock). In the subgroup with simple revascularization, the incidence of non fatal perioperative acute myocardial infarction (AMI) was 4.7% in 253 pts with unstable angina, 52.2% in 23 pts with abrupt closure during coronary angioplasty, and obviously 100% in 3 pts surgically treated during evolving AMI. We were able to identify in the univariate analysis as the only 30-day risk mortality factors: 1) a reduced ejection fraction (< 30%) and 2) the combination with endarterectomy. Other factors (female sex, age > 70, severity of angina, diffuse coronary artery disease and more than 3 by pass grafts) have shown a tendency to increase the mortality rate without statistical significance. No deaths occurred in pts revascularized in emergency situations due to coronary angioplasty complications. In recent years emergency and urgent coronary surgical operations have been increasing, with an increase in pts with higher risk factors. In pts with simple revascularization, 30-day mortality and incidence of myocardial infarction are similar to those of elective surgery. In pts with abrupt closure as a consequence of coronary angioplasty the mortality rate seems very low, while the incidence of infarction remains extremely high. These observations have allowed the development of an integrated protocol of intervention in acute unstable coronary syndromes.
