IMPACT OF LASER BLOOD IRRADIATION ON ELEC TRICAL VENTRICULAR INSTABILITY IN PATIENTS WITH PROGRESSIVE ANGINA-PECTORIS

The impact of laser blood irradiation (LBI) on electrical unstability has been studied in 71 patients with progressive angina pectoris. The amount of couplets of ventricular premature beats after LBI was decrea sed, as evidenced by 24-hour monitoring. Invasive programmed ventricul ar stimulation provided better electrophysiological properties of the myocardium after LBI: primary examination showed that electrical ventr icular instability was detected in 40 %, but after the therapy it was only in 20 % patients. Thus, LBI is an effective tool to decrease elec trical ventricular instability, a major risk factor for sudden coronar y death in patients with progressive angina pectoris.
