Individualizing Dual Antiplatelet Therapy After Percutaneous Coronary Intervention - The IDEAL-PCI Registry (IDEAL-PCI)

March 24, 2017 updated by: Prof. Dr. Guenter Christ, Kaiser Franz Josef Hospital
The purpose of this study is to determine the efficacy and safety of a routine individualized antiplatelet therapy after coronary stent implantation by evaluating "on-treatment" platelet reactivity with Multiple Electrode Aggregometry (MEA, Multiplate® Analyzer).

Detailed Description

Depending on the clinical presentation patients are treated according to standard operating procedures in our department. The earliest, 12 hours after an initial clopidogrel-loading dose (600mg)"on-treatment" platelet reactivity will be determined by Multiple Electrode Aggregometry (MEA, Multiplate® Analyzer), a point of care assay. In case of high residual platelet reactivity (i.e. ≥ 50U), patients are switched according to a therapeutic algorithm to either prasugrel (Efient®), or in case of contraindication (i.e. stroke) to ticagrelor (Brilique®), or in case of contraindication (intracranial hemorrhage) reloaded with clopidogrel.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Definite Stent Thrombosis
Time Frame: 30 days
The angiographic or pathological confirmation of stent thrombosis is called "definite stent thrombosis"
30 days
Any Bleeding Event
Time Frame: 30days

Bleeding classified by the TIMI hemorrhage classification scheme:

Minor: any clinically overt sign of hemorrhage (including imaging) that is associated with a hemoglobin drop of 3 to < 5 g/dL

Major: (1) if it is intracranial, or (2) clinically significant overt signs of hemorrhage associated with a drop inhemoglobin of > 5 g/dL
30days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Probable Stent Thrombosis
Time Frame: 30days

Probable stent thrombosis is considered to have occurred in case of

  1. any unexplained death within the first 30 days.
  2. any MI that is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of stent thrombosis and in the absence of any other obvious cause, irrespective of the time after the index procedure
30days
