E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine whether treatment with bivalirudin, compared with treatment with Unfractionated Heparin (UFH), for primary Percutaneous Coronary Intervention (PPCI) in large ST- segment elevation myocardial infarction (STEMI) can reduce infarct size assessed by cardiac magnetic resonance (CMR) at 5 days (defined as 5 days +/- 36 h from randomisation) after PPCI
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are to determine the effects of bivalirudin compared with UFH treatment for PPCI in STEMI on:
• Other CMR derived parameters of myocardial recovery 5 days after PPCI (i.e. left ventricular ejection fraction [LVEF], myocardial salvage index [MSI] and micro-vascular obstruction [MVO]).
• LVEF as assessed by CMR at 90 days
• Markers of thrombin activity and cell injury after reperfusion
• Coronary flow and microcirculation at end of PCI
• Survival at 90 days
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Title: Index microcirculatory resistance (IMR) and collateral flow index (CFI) sub-study
Objective: This sub-study hypothesizes that infusion of bivalirudin compared with UFH during primary PCI will reduce myocardial microvascular damage measured by the Index of Microcirculatory Resistance (IMR). |
|

(1) Child bearing potential is defined as:
A female patient is considered to have childbearing potential unless she meets at least one of the following criteria:
• Age ≥50 years and naturally amenorrhoeic for ≥ 1 year*
• Premature ovarian failure confirmed by a specialist gynaecologist
• Previous bilateral salpingo-oophorectomy, or hysterectomy.
• XY genotype, Turner’s syndrome, uterine agenesis.
*Amenorrhoea following cancer therapy does not rule out childbearing potential |
