Effect of Sacubitril/Valsartan on the recurrence of atrial fibrillation after catheter ablation

JRCT ID: jRCT1061230045

Registered date:08/08/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Atrial fibrillation
• Date of first enrollment: 08/08/2023
• Target sample size: 200
• Study type: Interventional

Intervention(s)

Sacubitril/Valsartan(SV) or Valsartan(V) should be started between the day before and the day after undergoing catheter ablation. The initial dose of SV is 100mg, V is 40mg once a day. The SV and V dose are titrated to 200mg, 80mg once a day respectively if the systolic pressure is > 120mmHg and no symptoms caused by hypotension. We try to reach to the target dose as possible, and it would be considered that other antihypertensive drug is gradually reduced and stopped until reaching the dose. Patients are a
dministrated SV or V account to the assined groupfor 12 months and then stopped the administration.

Outcome(s)

• Primary Outcome: Reccurence rate of atrial fibrillation 12 months after catheter ablation

Secondary Outcome

Supraventricular arrhythmias lasting >24 hours
Left atrial diameter and left atrial volume, peak atrial longitudinal strain
