[Ventricular arrhythmia in ischemic cardiopathy].
The authors undertook a retrospective study of 200 cases of documented ischaemic heart disease. Seven variables were considered in a statistical analysis: age, sex, localisation of myocardial lesions, left ventricular function, ventricular arrhythmias in density and grade, and death due to cardiac or other causes. The statistical analysis using the Chi squared test showed no correlation between death and the variables: age, sex and localisation of the infarct. However, statistically significant relationship was observed between death, in particular when due to cardiac causes, and: left ventricular function, especially when the ejection fraction was less than 0.40, ventricular arrhythmias, especially with a density of between 10 and 50% and when repetitive were observed. Analysis of correspondences confirmed these results. Log-linear analysis of the variables or combinations of variables which allows prediction of the prevalence of death showed ventricular arrhythmias to be more important than left ventricular function when these two variables were considered singly. When the association of two variables was considered, the best predictive association was ventricular arrhythmias with repetitive ectopic rhythms; the second best predictive association was ventricular arrhythmias with abnormal ventricular function. These results should be interpreted taking into consideration the patient group studied, the criteria of selection and the limitations of 24 h ECG monitoring; in addition, some arrhythmias may have added importance (e.g. ventricular parasystole).
