Conservative strategy

EXPERIMENTAL
Procedure: Conservative strategy

Aggressive strategy

EXPERIMENTAL
Procedure: Aggressive strategy

Interventions

* Main vessel stenting was performed. * Side branch ballooning and kissing ballooning were done if Thrombolysis In Myocardial Infarction (TIMI) flow \<3 in the side branch after main vessel stenting in non-left main bifurcation (non-LM) subgroup, and diameter stenosis (DS) \>75% in LM subgroup. * Side branch stenting was performed if TIMI flow \<3 in the Side branch after ballooning in non-LM subgroup, and DS \>50% or dissection in the Side branch after ballooning in LM subgroup.

Conservative strategy

* Main vessel was performed. * Side branch ballooning and kissing ballooning were done if DS \>75% in the side branch after main vessel stenting in non-LM subgroup, and DS \>50% in LM subgroup. * Side branch stenting was performed if DS \>50% in the side branch after ballooning in non-LM subgroup, and DS \>30% or dissection in the side branch after ballooning in LM subgroup.

Aggressive strategy
