If the arteries is narrowed or clogged, severe coronary artery disease (CAD) or coronary heart disease (CHD) such as cardiac arrhythmia, cardiac arrest and heart attack would happen which risk the lives of patients. Percutaneous coronary intervention (PCI) has become the most widely used method to treat patients with coronary artery disease[1]. Adverse events, such as restenosis and rare cases of stent thrombosis sometime develop after the procedure. Coronary drug-eluting stent (DES) implantation is increasingly used for the patients with coronary artery disease because its reduction of neointimal hyperplasia, decreased risk of restenosis and less frequent need for repeated
