Rationale and design of the Web-basEd soCial media tecHnology to improvement in Adherence to dual anTiplatelet Therapy following Drug-Eluting Stent Implantation (WECHAT): protocol for a randomised controlled study

BackgroundDual antiplatelet therapy (DAPT) is frequently discontinued after drug-eluting stent (DES) implantation, which could increase the risk of major adverse cardiovascular events (MACEs). Few studies have attempted to improve DAPT adherence through web-based social media.ObjectiveTo explore the effect of social media on DAPT adherence following DES implantation.Methods/designThe WeChat trial is a multicentre, single-blind, randomised study (1:1). It will recruit 760 patients with DES who require 12 months of DAPT. The control group will only receive usual care and general educational messages on medical knowledge. The intervention group will receive a personalised intervention, including interactive responses and medication and follow-up reminders beyond the general educational messages. The primary endpoint will be the discontinuation rate which is defined as the cessation of any dual antiplatelet drug owing to the participants’ discretion within 1 year of DES implantation. The secondary endpoints will include medication adherence and MACEs. Both groups will receive messages or reminders four times a week with follow-ups over 12 months.Ethics and disseminationEthical approval was granted by Ethics Committee of Guangdong Provincial People’s Hospital (GDREC2018327H). Results will be disseminated via peer-reviewed publications and presentations at international conferences.Trial registration numberNCT03732066

Objective: The aim was to evaluate the efficacy and safety of duration of dual antiplatelet therapy (DAPT) for patients who received percutaneous coronary intervention (PCI) with a drug-eluting stent. Background: The optimal duration of DAPT to balance the risk of ischemia and bleeding in CAD patients undergoing drug-eluting stent (DES) implantation remains controversial. Methods: PubMed, Cochrane Library, Web of Science, Clinicaltrials.gov, CNKI and Wanfang Databases were searched for randomized controlled trials of comparing different durations of DAPT after DES implantation. Primary outcomes were major adverse cardiac and cerebrovascular events (MACCE), and major bleeding, and were pooled by Bayes network meta-analysis. Net adverse clinical and cerebral events were used to estimate the surface under the cumulative ranking (SUCRA) curves. The subgroup analysis based on clinical status, follow-up and area was conducted using traditional pairwise meta-analysis. Results: A total of nineteen trials (n=51,035) were included, involving six duration strategies. The network metaanalysis showed that T2 (<6-month DAPT followed by aspirin, HR:1.51, 95%CI:1.02-2.22), T3 (standard 6-month DAPT, HR:1.47, 95%CI:1.14-1.91), T4 (standard 12-month DAPT, HR:1.41, 95%CI:1.15-1.75) and T5 (18-24 months DAPT, HR:1.47, 95%CI:1.09-1.97) was associated with significantly increased risk of MACCE compared to T6 (>24-month DAPT). However, no significant difference was found in MACCE risk between T1 (<6-month DAPT followed by P2Y12 monotherapy) and T6. Moreover, T5 was associated with significantly increased risk of bleeding compared to T1(RR:3.94, 95%CI:1.66-10.60), T2(RR:3.65, 95%CI:1.32-9.97), T3(RR:1.93, 95%CI:1.21-3.50) and T4(RR:1.89, 95%CI:1.15-3.30). The cumulative probabilities showed that T6(85.0%), T1(78.3%) and T4(44.5%) were the most efficacious treatment compared to the other durations. In the ACS (<50%) subgroup, T1 was observed to significantly reduce the risk of major bleeding compared to T4, but not in the ACS (≥50%) subgroup. Conclusions: Compared with other durations, short DAPT followed by P2Y12 inhibitor monotherapy showed non-inferiority, with a lower risk of bleeding and not associated with an increased MACCE. In addition, the risk of major bleeding increased significantly, starting with DAPT for 18-month. Compared with the short-term treatment, patients with ACS with the standard 12-month treatment have a better prognosis, including lower bleeding rate and the decreased risk of MACCE. Due to study's limitations, the results should be verified in different risk populations.
