Treatment
All patients were treated with the optimal medical treatment for STEMI, including aspirin, P2Y12 inhibitor, statin, beta blocker, LMWH, and nitrate based on the patient’s condition. We randomized all patients into four groups. The first group consisted of patients who received late PCI with the loading of colchicine 1 mg 1 h before late PCI, and colchicine 0.5 mg 1 h after late PCI was done, and continued with colchicine 0.5 mg daily for 5 days. The second group received late PCI and optimal medical treatment for 5 days. The third group consisted of patients who got optimal medical treatment and received the loading of colchicine 1 mg 1 h before entering ICCU, colchicine 0.5 mg 1 h after that, and continued with colchicine 0.5 mg daily for 5 days. The fourth group are patients who get optimal medical treatment for 5 days without colchicine.
