Abstrakt: Unlabelled: The purpose of this investigation is to evaluate the influence of purified highly-concentrated omega-3 polyunsaturated fatty acids (90% omega-3 polyunsaturated fatty acids 1 g/day) on the severe ventricular arrythmias in patients with stable coronary heart disease (CHD) without concomitant left ventricular contractivity impairment.
Materials and Methods: 43 patients with stable CHD (26 male and 17 female, aged 66.2 +/- 8.3) with ejection fraction above 45% with unstable paroxysms of ventricular tachycardia detected at Holter ECG monitoring that received 1 g/day omega-3 polyunsaturated fatty acids during 1 month. 23 patients continued treatment for one month extra, while 20 stopped receiving after one month. ECG monitoring was repeated monthly.
Results: In one month after started receiving 90% omega-3 polyunsaturated fatty acids the mean heart rate reduced by 2.4%, the number of single extrasystoles reduced by 20.1% (p=0.01), the number of paired extrasystoles reduced by 47% (p=0.0018) and the number of paroxysms reduced by 49% (p=0.0029). In 41.9% patients no paroxysms have been registered after one month. When continuously receiving omega-3 polyunsaturated fatty acids during the second month, the treatment efficiency increases, while the receiving been stopped after one month, the effect is reduced but remains.
Conclusion: 1 g/day omega-3 polyunsaturated fatty acids application in patients with stable CHD without myocardium contraction dysfunction suffering from ventricular arrhythmias (4B grade after B.Lown) with no direct indications for implantable cardioverter defibrillator therapy results in significant reduction of arrhythmia.
