Vascular and myocardial inflammation are significantly increased in Acute Coronary Syndrome (ACS) patients, are closely correlated to LDL-C levels, and are associated with these adverse consequences in the post-ACS patient population. Serum proprotein convertase subtilisin/kerin type 9 (PCSK9) levels are also increased in ACS, may raise LDL-C, and the investigators' pre-clinical studies indicate that PCSK9 is also a potent inducer of vascular inflammation. The addition of the PCSK9 antibody evolocumab, currently approved to lower LDL-C in certain patient populations, to current medical therapies would appear to be of particular benefit in an important subset of ACS patients, those with non-ST elevation myocardial infarction (NSTEMI) by markedly reducing LDL-C, stabilizing vulnerable plaque, and limiting inflammation-associated myocardial cell loss and resultant dysfunction.


In a placebo-controlled, randomized double blind trial, the addition of evolocumab to standard care in NSTEMI patients (1) decreases LDL-C during hospitalization and at 30 days, (2) decreases vascular/plaque and myocardial inflammation as assessed by Positron Emission Tomography (PET) scanning at 30 days, and improves (3) serum markers of endothelial function at hospital discharge and at 30 days, and (4) echocardiographic assessment of left ventricular function at 30 days and six months.

This is the first PCSK9 inhibitor trial which examines these outcomes in the ACS patient population. It will provide valuable data on the extent and time course of LDL-C reduction as well as the impact of inhibition on inflammatory markers and on imaging assessment of vascular and myocardial inflammation, all of which may significantly impact important clinical outcomes in this high risk patient cohort.
