Timing of Coronary Angiography in NSTE-ACS With ADHF

The investigators hypothesized that immediate coronary angiography (CAG) within 2 hours after admission can reduce mortality compared to delayed CAG after stabilization of acute decompensated heart failure (ADHF) in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) complicated by ADHF. Patients with NSTE-ACS complicated by ADHF will be randomized to immediate CAG (coronary angiography \< 2 hours after randomization) or delayed CAG after stablization group by 1:1 fashion. This study is a prospective, non-blinded, randomized trial.
