Functional Improvement of coronary artery narrowing by cholesterol reduction with a PCSK9 Antibody
- Conditions
- Coronary artery disease (CAD) Optimal treatment approach for bystander lesions in non-infarct related arteries (non-IRA’s) has not been well established. Multiple RCT’s favor preventive PCI over medical treatment, however medical treatment wasn’t optimal in these studies. We want to investigate if optimizing LDL-lowering therapy after an ACS has an effect on functional impairment of a non-IRA lesion and could thus prevent mechanical intervention (PCI or CABG).Therapeutic area: Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Therapeutic techniques [E02]

Subjects must have an eligible LDL-C level via local lab assessment based on statin use at screening:
- No statin use: = 130 mg/dL (3.3 mmol/l)
- Non-intensive statin use (see Table): = 80 mg/dL (2.0 mmol/l)
- Intensive statin use (see Table): = 60 mg/dL (1.6 mmol/l)
- Age = 18 years at screening

- Primary Outcome Measures
Name Time Method Main Objective: To evaluate the effect of maximal LDL-C reduction by Evolocumab on top of optimal background lipid-lowering therapy (ESC guidelines) on FFR of non-IRA lesions, in patients presenting with MVD-ACS. <br>;Secondary Objective: Secondly to correlate baseline lipid core burden with changes in FFR and to investigate the relation between LDL reduction and change in pro-inflammatory monocyte phenotypes.;Primary end point(s): The primary study parameter is the change in FFR from baseline to follow-up in non-IRA lesions. ;Timepoint(s) of evaluation of this end point: At 14 weeks (12+2) participants will undergo FFR/NIRS for a second time, which whill produces the values needed for the primary endpoint.
- Secondary Outcome Measures
Name Time Method Secondary end point(s): The secondary endpoint is the correlation between baseline Near-InfraRed Spectroscopy (NIRS) derived lipid core burden (MaxLCBI4mm) and change in FFR of the non-IRA.;Timepoint(s) of evaluation of this end point: Please see E.5.1.1
