Long Term Follow-up of Comparison of Clopidogrel vs. Aspirin Monotherapy After Drug-eluting Stent Implantation — HOST-EXAM-EX  

Coronary Artery Disease Clinical Trial

Official title:
HOST-EXAM-Ex : Harmonizing Optimal Strategy for Treatment of Coronary Artery Stenosis - EXtended Antiplatelet Monotherapy - EXtended Follow up

Clinical Trial Summary

This is an retrospective extended study of a randomized clinical trial (The HOST-EXAM trial ClinicalTrials.gov Identifier: NCT02044250). Investigators will perform a retrospective analysis of all participants enrolled in this trial will be performed, until the longest follow-up duration.

Clinical Trial Description

The HOST-EXAM trial (ClinicalTrials.gov Identifier: NCT02044250) was an randomized clinical trial that was performed to compare head-to-head, the efficacy and safety between aspirin and clopidogrel monotherapy in patients who received PCI for coronary artery disease and required chronic maintenance antiplatelet therapy. From March 2014 through May 2018, a total of 5438 patients were enrolled, and follow-up was performed upto 24 months after randomization. After this study, randomization was unlocked and patients were followed-up based on the standard protocol. Afterwards, the current study was planned to perform a extended follow-up of the HOST-EXAM population. The specific drug by the randomization group in the HOST-EXAM trial was not mandatory after the initial 24 months, therefore participants received medication according to the current guidelines, and according to the physicians preferences. This is a observational, retrospective analysis of all clinical events after the randomization period. The prescribed medications and any clinical events will be evaluated. ;
