干预措施:

Interventions:

组别:

药物涂层球囊治疗组

样本量:

1246

Group:

Drug coated balloon therapy group

Sample size:

干预措施:

DCB治疗后双抗1个月,后改为单抗(首选氯吡格雷)治疗(若患者同时口服抗凝药物,单抗板+抗凝药1月后,改为单抗凝)

干预措施代码:

Intervention:

After DCB treatment, dual antiplatelet therapy (DAPT) is administered for 1 month, followed by single antiplatelet therapy (preferably clopidogrel). If the patient is taking oral anticoagulant drugs at the same time, single antiplatelet therapy combined with anticoagulant drugs is given for 1 month, then switched to single anticoagulant therapy.

Intervention code:

组别:

DES治疗组

样本量:

1246

Group:

DES treatment group

Sample size:

干预措施:

DES植入后,双抗至少6个月,后根据术者自行决定抗板方案(若患者同时口服抗凝药物,双抗+抗凝1月后,改为单抗+抗凝)

干预措施代码:

Intervention:

After DES implantation, dual antiplatelet therapy (DAPT) is administered for at least 6 months, and then the antiplatelet regimen is determined by the operator at his/her discretion. If the patient is taking oral anticoagulant drugs at the same time, dual antiplatelet therapy combined with anticoagulant drugs is given for 1 month, then switched to single antiplatelet therapy combined with anticoagulant drugs.
