**3. In the future**

Developments in stent technology and novel drugs inhibits platelet aggregation are decreasing the complications of stent implantation. By completely absorption of stent material in novel stents, dual anti-platelet therapy shortens and overall late stent thrombosis and revascularization rates decreases. Recently, endothelial progenitor cell-capturing stent technology contributes re-endothelialization. With the improvement in therapeutic modulations, incidences of cardiogenic shock due to stent thrombosis and mortality rates are in decreasing tendency.
