Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Evolocumab, 420 milligrams
Single injection of 420 milligrams of evolocumab (REPATHA®) one month before coronary angiography and coronary microcirculation (IMR) measurement.
Evolocumab 140 MG/ML [Repatha]
3 injections of evolocumab 140 milligrams performed within 30 minutes and self-administered (subcutaneously in the abdomen, thigh, or upper arm)
Control arm
Measurement of coronary microcirculation (IMR) during coronary angiography, without prior evolocumab injection.
No interventions assigned to this group
