Comparative Study
[Surgical revascularization in acute coronary insufficiency: an analysis of the risk factors for hospital mortality in urgencies and emergencies].
A retrospective analysis of 444 patients (Pts) with acute coronary insufficiency (A.C.I.) submitted to coronary artery bypass grafting between January '85 and December '92 was performed in order to identify incremental risk factors associated with perioperative mortality and to evaluate whether prediction of mortality can be accomplished utilizing risk models specifically linked to the severity of myocardial ischemia. ⋯ A useful stratification of Pts with A.C.I. in three different groups, each with its own risk model, can be obtained by means of clinical-ECGraphic criteria alone. Different prognostic weights can be attributed to the variables A.C.C.T., E.F. and non-use of B.C. depending on clinical status. A significant reduction of mortality rate in Pts with cardiogenic shock can be achieved by the utilization of individually-tailored surgical management.
