What are the complications of interventional treatment for coronary heart disease?

Arteriovenous complications may occur, particularly following femoral artery puncture, which can lead to hematoma formation at the puncture site; if left untreated, this hematoma may progress. Additionally, because patients receive antiplatelet agents pre- and post-procedure and heparin for anticoagulation during the procedure, bleeding is a common perioperative complication. Based on the patient’s symptoms, further evaluation—including electrocardiography (ECG), cardiac enzymes, troponin assays, or repeat coronary angiography—may be warranted, and prompt treatment should be initiated.
