Abstract
Clinical variables and the results of non-invasive tests (exercise test, echocardiogram, gated equilibrium radionuclide ventriculography and 24 h ECG) were recorded in a series of 202 patients who left the hospital alive after an acute myocardial infarction.
The short term (two months) predictive value of all these data was prospectively assessed by uni- and multi-variate analysis. The best correlation with early death was observed with the variables related to the extent of infarction and left ventricular dysfunction, namely: early clinical signs of heart failure, high peak CK-MB level, complete bundle branch block, increased cardiothroacic ratio on chest X-Ray,number of Mets reached during the stress test, echocardiographic dyskinesia index, and decreased left ventricular ejection fraction as measured by radionuclide ventriculography.
Using multi-variate stepwise discriminant analysis, the following independent prognostic factors appeared by order of entry: early clinical signs of heart failure, peak CK-MB level and cardiothoracic ratio on chest X-Ray.
These results highlight the short-term predictive value of the data related to left ventricular dysfunction and especially of simple clinical data for patients surviving an acute myocardial infarction.
