E.5 End points |
E.5.1 | Primary end point(s) |
The effect of early administration of eplerenone will lead to:
• Reduction of the LV fibrosis assessed by CMR method MOLLI
• Influence of LVEDV, LVESV, EF asssessed by MR
• Decrease of the serum concentration of galectin-3
• Reduction of ventricular ectopic assessed by 24 h ECG Holter
Predictive factor for LV pathological remodeling is:
• The rate of early microvascular obstruction assessed by MRI |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Ambulatory monitoring in the 1st and 6th month •
Standard 12-lead ECG during AMI, before the discharge of the patient at the end of the first week after AMI, in the 1st and 6th month
• Left ventriculography performed during acute coronary angiography
• Echocardiographic examination within 48 hours of AMI (in case that left ventriculography is not performed, echocardiographic examination will be performed before randomization), before discharge of the patient at the end of the first week after AMI and at 6 months
•CMRduring the first week of AMI (minimum 96 hours after AMI) and at 6 months
• Serum biomarkers (BNP, Galectin-3, cortisol, aldosterone, plasma renin activity) - before randomization, before discharge, as well as in the 1st and 6th month |
|
E.5.2 | Secondary end point(s) |
The effect of early administration of eplerenone will lead to:
• Decline in serum concentrations of BNP
• Shortening of QRS interval duration
• Favorable impact on ECG markers related to arrhythmogenesis
Predictive factors for LV pathological remodeling LK are:
• The period of ischemia
• The size of infarct on assessed on initial MRI scans |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
•Signal-averaged ECG in the first week of AIM (at least 72 hours after AMI) and at 6 months
• Ultra-high-frequency (UHF) ECG in the first week after AIM (at least 72 hours after AIM) and at 6 months
