Abstract/OtherAbstract:
It is well known that patients with coronary heart disease and ventricular tachycardia show a high incidence of arrhythmogenic complications and sudden cardiac death. The best predictor of spontaneous ventricular tachycardia and sudden death in these patients is programmed ventricular stimulation, but this invasive method is limited to specialized institutions. The purpose of our study was to assess the predictive value of Holter monitoring, late potentials and heart rate variability as markers for these high-risk patients. We investigated 20 patients (18 m, 2 f, age range 31-79 years) with coronary artery disease documented angiographically (6 patients with single vessel disease (vd), nine patients with 2 vd, five patients with 3 vd) and previous myocardial infarction. Each patient underwent 24-h ambulatory monitoring with analysis of rhythm of heart rate variability (24-h spectral and non-spectral analysis) and a signal-averaged ECG with late potential measurement. In all patients, sustained ventricular tachycardia was inducible during programmed ventricular stimulation. Late potentials were recorded in 12 out of the 20 patients (60%). Ventricular arrhythmias of Lown classes IVa, IVb or V were recorded in 12 patients. Analysis of heart rate variability compared to 20 age- and sex-matched healthy controls revealed a loss of parasympathic activity and increased sympathic activity in 16 of the 20 patients (80%). Conclusion: in this study, heart rate variability was the most sensitive method with which to recognize patients at a high risk of arrhythmogenic complications. Evaluation of the above parameters in large controlled clinical trials may help predict arrhythmogenic complications and sudden cardiac death.
