[Myocardial infarct after the acute phase--the risk of arrhythmia].
Upon the development, divulgation and improvement of the Ambulatory Electrocardiographic Monitoring (AEM) techniques, the problem of the arrhythmias after an acute myocardial infarction (AMI) has acquired a new acuteness. Its importance becomes clearly evident from the fact today recognized that about 10% of the patients die within the first year after AMI and that the great majority of them dies suddenly. The prognostic value of certain types of ventricular arrhythmias is now well proved to be an independent risk factor respecting to the late complications of AMI, namely the sudden death issue. In this paper, after referring the prognostic criteria for the ventricular arrhythmias, the Author proposes an AEM execution calendar for the AMI patients, since the late hospital phase (hospital discharge). Afterwards, the controversial therapeutic problem of the ventricular arrhythmias is approached, quoting the pharmacological set-backs and pointing out the AEM limitations in regard to the selection and efficacy confirmation of the anti-arrhythmic drugs. At last, a few conclusions of the "Cardiac Arrhythmia Pilot Study" (CAPS, 1986) are mentioned and an other ongoing multicenter study is referred, whose conclusions will be of capital importance to define the anti-arrhythmic therapy utility in the setting of the post-AMI patients.
