Management of patients after radiofrequency ablation of pulmonary veins
The study included 40 people with atrial fibrillation (AF). The examination report included: ECG- 12, echocardiography, ECG monitoring (DM ECG), biochemical blood tests (lipid profile, CRP, homocysteine, interleukin-6 (IL-6), pro-BNP), and diaries-chronological cards (DCA). Depending on the presence of recurrence in the period of 3 to 6 months after surgery, the patients were divided into 2 groups: with and without relapse. In the group of recurrence the level of IL-6 before surgery was significantly higher (p=0.034). Threshold value for IL-6 is 1.77 mmol/L. Above it the possibility of development of AF recurrence in 6 months after RFA LP increases by 9.8 times. In the group of recurrence level the maximal HR is significantly higher before surgery (р=0.017) according toSM ECG. Threshold value for maximal heart rate is 120 beats/m. Above it the possibility of distant recurrence increases by 5.45 times. The incidence of AF registered in DM ECG in the recurrence group was significantly higher in 1 and 3 months after RFA PV (p=0.02 and p=0.01, respectively). The presence of relapse after 1 month after the procedure increases the risk of distant recurrence by 21 times. The highest proportion of asymptomatic paroxysmal AF after RFA is registered in the first day after RFA LP and makes 36% (40% in patients with paroxysmal AF).On the base of analysis of the mentioned parameters there was offered the algorithm for management of patients after radiofrequency ablation of pulmonary veins.
