E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate an increase of near maximal hyperaemic myocardial blood flow (MBF ml/min/g) after treatment with ranolazine. Measurement of myocardial perfusion with 13N-ammonia and positron emission tomography; assessment of hyperaemic Myocardial Blood Flow (MBF) following i.v. dipyridamole (0.56 mg/Kg in 4 mins). |
dimostrare un aumento del flusso miocardico iperemico massimale (MBF) (ml/min/g) dopo trattamento con Ranolazina. Misurazione della perfusione miocardica con PET 13N-ammoniaca; valutazione del flusso iperemico miocardico dopo infusione di dipiridamolo (0.56 mg/Kg in 4 minuti). |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate an increase of Coronary Flow Reserve (hyperaemic MBF /resting MBF = CFR). A decrease of baseline coronary resistance (Mean Arterial Pressure rest/ MBF rest) and of minimal (dipyridamole) coronary resistance (Mean arterial Pressure hyperemia/ MBFhyperemia) |
dimostrare un aumento della riserva coronarica di flusso (CFR= MBF iperemico/MBF basale). Dimostrare una riduzione delle resistenze coronariche basali (pressione arteriosa media basale/MBF basale) e delle resistenze coronariche durante massima vasodilatazione con dipiridamolo (pressione arteriosa media in iperemia/MBF in iperemia). Valutazione della safety per mezzo di : Alterazioni nell’elettrocardiogramma di superficie a 12 derivazioni comprendenti la valutazione degli intervalli RR QT JT e del QRS in V2 V3.
