Association of lipoprotein(a) with long‐term mortality following coronary angiography or percutaneous coronary intervention

Background There is no consistent evidence to suggest the association of plasma lipoprotein(a) (Lp[a]) with long-term mortality in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI). Hypothesis Level of Lp(a) is associated with long-term mortality following CAG or PCI. Methods We enrolled 1684 patients with plasma Lp(a) data undergoing CAG or PCI between April 2009 and December 2013. The patients were divided into 2 groups: a low-Lp(a) group (Lp[a]
