Web basEd soCial Media tecHnology to Improvement in Adherence to Dual anTiplatelet Therapy Following Drug-Eluting Stent Implantation (WeChat), a Randomized Controlled Branch on Antiplatelet of RESCIND Study

Few studies have attempt to improve DAPT adherence through social media. The investigators will explore the prevalence of DAPT discontinuation and prove the hypothesis that using social media will improve DAPT adherence among patients requiring DAPT following DES implantation.

Dual antiplatelet therapy (DAPT) is frequently discontinued after drug-eluting stent (DES) implantation, which could lead to many major adverse cardiovascular events (MACEs). Social media have been proven effective in improving lifestyles and blood pressures control, but few studies have attempt to improve DAPT adherence through social media.Therefore, eligible patients will be enrolled through scanning QR code and randomized in a 1:1 ratio to an intervention group or control group with 12 months of follow-up.The investigators will find out the prevalence of DAPT discontinuation and prove the hypothesis that using social media will improve DAPT adherence among patients requiring DAPT following DES implantation..
