Abstract
It is known that ventricular dysrhythmias in patients with ischemic heart diasease can be of various origin. Hence selection of antiarrhythmic tactics in such patients should be individual and pathogenetically proved.
Aim. To check antiarrhythmic abilities of metabolic therapy for ischemic heart disease combined with variety of ventricular arrhythmias of III-IV grades (by Myerburg RJ).
Material and methods. for 42 patients with ventricular arrhythmias of high grade and stable ischemic heart disease with saved ejection fraction of the left ventricle, before and after treatment were done the following: Holter monitoring, treadmill test, and as indicated — coronary arteriography, radionuclide methods of perfusion assessment and metabolism of myocardium, non-invasive topical diagnostics. To individually selected antianginal and antihypertension therapy for all patients was added ethylmethylhydroxypyridine succinate (es) in daily dosage 300 mg, for 2 months.
Results. During the study, according to relationship of ventricular arrhythmia with transient ischemia, patients were selected to 2 groups. In the 1 group, with ischemic arrhythmias, in 2 months after start of es, there was significant antiarrhythmic effect: number of single ventricular premature beats decreased by 55%, couplets — by 90%, and episodes of non-sustained ventricular tachicardia — by 100%. At control positrone-emisson tomography in the areas of myocardial ischemia there was significant increase of 11C-buthirate sodium excretion, which witness on the increase of efficacy of energetic metabolism in zones of hypoxia. In the II group, with non-ischemic ventricular arrhythmias — antiarrhythmic effect was not achieved. Conclusion. es should be regarded as pathogenetic chain in complex antiarrhythmic treatment of ventricular arrhythmias in patients with stable ischemic heart disease.
