High lipoprotein(a) levels predict severity of coronary artery disease in patients hospitalized for acute myocardial infarction. Data from the French RICO survey

•This study presents data on CAD severity in patients with acute MI and high Lp(a).•Patients with high Lp(a) had poorer survival during hospitalization for acute MI.•Very high Lp(a) levels (> 100 mg/dL) are associated with a severe CAD burden.•A call to action is needed for Lp(a) screening in all patients with acute MI.
