myocardial infarction

Pharmacologically lowering low-density lipoprotein cholesterol (LDL-C) consistently reduces ASCVD events (myocardial infarction, stroke, and cardiovascular death), and the principle that lower LDL-C is better was reaffirmed by trials that added ezetimibe or proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors to statin therapy. The 2013 guideline removed specific LDL-C treatment targets, but high-quality trials since offered the opportunity to reintroduce such goals based on risk gradations.
