Optimized Antiplatelet Therapy on the Prognosis of ACS Patients With Non-predominant Coronary Artery Disease After PCI

May 11, 2020 updated by: Lianglong Chen, Fujian Medical University

A Prospective, Randomised, Open-labeled, Parallel Group Study to Assess the Effect of Optimized Antiplatelet Therapy on the Prognosis of ACS Patients With Non-predominant Coronary Artery Disease After PCI

The study is to evaluate the effect of optimized 12-month step-down antiplatelet therapy (APT) compared with standard 12-month dual antiplatelet therapy in clinical net adverse events, cardiovascular and cerebrovascular adverse events and reducing clinical related bleeding events in the patients with acute coronary syndrome (ACS) who are not the predominant coronary artery disease after percutaneous coronary intervention (PCI).

Study Overview

Detailed Description

This is a prospective, multi- center, randomized, parallel-group trial designed to evaluate the effect of optimized 12-month step-down antiplatelet therapy compared with standard 12-month dual antiplatelet therapy in clinical net adverse clinical events, cardiovascular and cerebrovascular adverse events and reducing clinical related bleeding events in the patients with acute coronary syndrome who are not the main coronary artery disease.2020 subjects will be enrolled. After PCI,eligible patients will be randomly assigned in a 1:1 ratio to either the optimized antiplatelet therapy group(O-APT)or the standard antiplatelet therapy group(S-APT). The primary efficacy end points are clinical net adverse clinical events ,or the event rate of the composite of cardiovascular death, non-fatal myocardial infarction, stent thrombosis, ischemia driven coronary revascularization and stroke at 12 months. The primary safety end point is the incidence of PLATO major bleeding or Bleeding Academic Research Consortium (BARC) type 2, 3 or 5 bleeding at 12 months.
