E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of the study is to show that STEMI patients who are pre-treated with crushed ticagrelor and paracetamol have a higher level of platelet inhibition after primary PCI than patients pre-treated with crushed ticagrelor who are treated with fentanyl |
De doelstelling van de studie is om te laten zien dat STEMI-patiënten die zijn voor behandeld met gemalen ticagrelor en paracetamol een hoger niveau van plaatjes remming na primaire PCI hebben dan patiënten die zijn behandeld met gemalen ticagrelor en die zijn behandeld met fentanyl |
|
E.2.2 | Secondary objectives of the trial |
-To demonstrate that paracetamol is non-inferior to fentanyl in pain reduction in STEMI patients.
- To show that patients with STEMI who are pre-treated in the ambulance with crushed ticagrelor 180 mg and paracetamol have a higher level of platelet inhibition than patients pre-treated with crushed ticagrelor 180 mg and fentanyl at other time points (T1, T3, T4).
- To show that patients with STEMI who are pre-treated in the ambulance with crushed ticagrelor 180 mg and paracetamol have a higher active metabolite of ticagrelor and AR-C124910XX measured in plasma than patients pre-treated with crushed ticagrelor 180 mg and fentanyl at the four time points (T1, T2, T3, T4).

E.5 End points |
E.5.1 | Primary end point(s) |
The priamry endpoint to show that patients with STEMI who are pre-treated in the ambulance with crushed ticagrelor 180 mg and paracetamol have a higher level of platelet inhibition directly after primary PCI (T2) than patients pre-treated with crushed ticagrelor 180 mg and fentanyl. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Blood sample measurements for platelet function testing and level of active metabolite of ticagrelor, using Verify Now P2Y12 assay (Accumetrics, San Diego, California), will be done at four time points:
T1: when arriving at the cathlab
T2: directly post-primary PCI or 1 hour after coronary angiography
when no PCI was performed
T3: one hour post-primary PCI including electrocardiogram (ECG) or
2 hours post-coronary angiography
T4: six hours post-primary PCI of 7 hours post-coronary angiography
|
|
E.5.2 | Secondary end point(s) |
Secondary endpoints:
-To demonstrate that paracetamol is non-inferior to fentanyl in pain
reduction in STEMI patients, measured by the level of pain using
numeric rating score.
-The level of platelet inhibition (PRU) at T1, T3 and T4.
-The percentage of High on treatment Platelet Reactivity (HPR) as
defined as a PRU >208 at T1, T3 and T4.
-The level of the active metabolite of a higher active metabolite of
ticagrelor and AR-C124910XX measured in plasma, at T1, T2, T3
and T4.
-Extent of ST-segment deviation (≥70% ST-segment resolution) pre-
PCI and 1 hour post-PCI.
-TIMI flow grade 3 in the culprit vessel at initial angiography.
-Requiring of fentanyl in patients randomized to paracetamol.
-MACE and stent thrombosis at 30 days of follow-up.
