Brief Summary:
This protocol describes a pilot study intended to test the hypothesis that patients with acute coronary syndrome (ACS) caused by plaque erosion can be stabilized by effective antithrombotic treatment without stent implantation, thereby avoiding both early and late complications related to percutaneous coronary intervention (PCI).

Condition or disease Intervention/treatment Phase
Acute Coronary Syndrome Drug: Ticagrelor Phase 4

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 250 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Plaque Erosion: A New in Vivo Diagnosis and Paradigm Shift in the Treatment of Patients With Acute Coronary Syndrome
Study Start Date : August 2014
Actual Primary Completion Date : April 2016
Actual Study Completion Date : April 2017

Resource links provided by the National Library of Medicine

Drug Information available for: Ticagrelor

Arm Intervention/treatment
Patients with ACS treated medically Drug: Ticagrelor

Primary Outcome Measures :
  1. Reduction of thrombus burden by OCT [ Time Frame: 30 days ]
    The efficacy will be assessed by 50% reduction in thrombus burden by OCT at 1 month.

Secondary Outcome Measures :
  1. Cardiovascular adverse events [ Time Frame: 30 days and 12 months ]
    In patients treated conservatively, the safety objectives are to evaluate the occurrence of any adverse events during1 month follow up (re-infarction, re-hospitalization, revascularization by PCI or CABG, cardiac death, stoke, and major bleeding).

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Men or non-pregnant women >18 years of age and < 75 years of age
  • Patients undergo cardiac catheterization for ACS. Patients with STEMI, NSTEMI, and UAP will be included. STEMI will be defined as continuous chest pain for >30 minutes, arrival at the hospital within 12 hours from chest pain onset, ST-segment elevation >0.1 mV in at least two contiguous leads, or new left bundle-branch block on the 12-lead electrocardiogram (ECG), and elevated cardiac markers (troponin T/I or creatine kinase-MB). NSTEMI will be defined as a progressive crescendo pattern of angina or angina at rest, in the absence of ST-segment elevation on the 12-lead ECG, with elevated cardiac markers. UAP will be defined as new onset angina, progressive crescendo pattern of angina, or angina at rest.
  • Culprit lesion located in a native coronary artery
  • TIMI flow grade 3 and diameter stenosis < 70% on angiogram
  • Definite erosion defined by OCT
  • Patients able to provide written informed consent

Exclusion Criteria:

Left ventricular ejection fraction < 30%.

  • Life expectancy < 1 year.
  • Contraindication to the contrast media.
  • Creatinine level > 2.0 mg/dL or end-stage kidney disease.
  • Serious liver dysfunction.
  • Patients with hemodynamic or electrical instability (including shock).
  • Any contraindication against the use of ticagrelor.
  • Investigator considers the patient is not suitable.
