TREATMENT RESULTS OF PATIENTS WITH VENTRICULAR ARRHYTHMIAS ACCOMPANIED BY CORONARY ARTERY DISEASE AT NGHE AN GENERAL FRIENDSHIP HOSPITAL
Main Article Content
Abstract
Objective: Evaluate the treatment results of patients with ventricular arrhythmias with coronary artery disease at Nghe An General Friendship Hospital. Subjects and methods: 31 patients were diagnosed ventricular arrhythmias, classified ≥ Lown 2 at Nghe An General Friendship Hospital. Patients were perform coronary angiography through the catheter and evaluated the results using QCA method. The patients have coronary artery stenosis ≥ 70% (significant stenosis). The patients were treated for ventricular arrhythmias: medication, treatment with radiofrequency energy (RF) and a combination of the above two methods. We followed and evaluated the early results of treatment for ventricular arrhythmia at the time the patient was discharged from the hospital. Results: General treatment methods of the research group: Medical therapy was 19.4%, RF ablation was 9.6%, coronary artery intervention with medical treatment accounts 71%. The overall treatment results of the research group showed that the rate of effective treatment of ventricular arrhythmias was 80.6%, of which 56.1% of patients had completely successful treatment of premature ventricular contractions (PVC), and 06 patients had treated ineffective results, accounting for 19.4%. In patient group still had PVC after treating, accounting for 48.4%, including 29% of patients with ventricular arrhythmias had reduced, the quantity of patients with PVC was unchanged accounting for 19.4%. In the group of significant coronary artery stenosis, the rate of patients with coronary artery stents placement was 71% and 10 patients did not receive coronary artery intervention, accounting for 32.3%. In the group that received intervention with coronary stent placement, the rate of effective treatment of ventricular arrhythmias accounted for 76.2%, of which the rate of successful treatment was 57.1%. Conclusion: The rate of effective treatment of ventricular arrhythmias in the study group accounted for 80.6%, of which the rate of patients without ventricular premature contraction after treating accounted for 51.6%; The patients with ventricular arrhythmias had unchanged results after treating accounted 19.4%. The patients was intervented coronary artery through catheter accouting for 71%, of which the effective treatment rate was 76.2%.
