Abstract 【Objective】To study the prognostic factors of patients with hypertrophic cardiomyopathy with atrial fibrillation of different risk of sudden death, so as to provide a reference for the treatment of HCM with atrial fibrillation with different risk of sudden death by radiofrequency ablation.【Methods】A total of 90 patients with HCM underwent AF catheter radiofrequency ablation from 2012 to 2015 were collected and analyzed. According to the 5-year risk assessment of sudden death, 27 cases were assigned into high risk group and 43 cases in low risk group (20 cases were excluded due to the same type of AF). All of them were followed up for (3.14 ±1.53) years, and the risk factors of prognosis between the two groups were compared.【Results】In 70 patients, 6 patients died, accounting for the total number of 8.5%, 4 of whom died of sudden cardiac death, 2 were non cardiogenic, and 12 had cardiogenic rehospitalization. In the COX scale risk model, the survival rate of the low risk group was significantly higher than that of the high risk group, and the results also showed that hs-CRP and left ventricular ejection fraction (LVEF) were the main risk factors for postoperative survival in the high risk group, while age was the main risk factor in the low risk group.【Conclusion】During clinical treatment, the hs-CRP value of patients with high risk of sudden death should be closely monitored and the postoperative nursing care should be strengthened according to the value of left ventricular ejection fraction (LVEF).
