Dynamics of paroxysmal atrial fi brillation (PAF) in two groups of the ischemic heart disease patients was analyzed during three year follow-up period. Th e 1st group included 115 patients with preoperative PAF that had undergone coronary bypass graft ing (CBG); 149 patients of the 2nd group who had received treatment by medication. Th e risk transformation of PAF in the permanent form was calculated with the use of indications having been distinguished through multivariate analysis. In the CAG patients the risk index was calculated also three months aft er surgery. It was found that CAG surgery is followed by signifi cant positive dynamics in the contraction of the left ventricular, left atrial dimension and reduction of the left atrial ectopic activity which included PAF frequency. In a three-year follow up, the risk of PAF transformation in the permanent form in the patients CAG, in comparison with those of the 2nd group on medical treatment, was signifi cantly lower. It is shown that for prognostic purposes in aft er CAG patients it is more eff ective to use risk indicators registered three month after surgery. Refs 12. Tables 3.
