- Abstract
Background: High levels of lipoprotein(a) [Lp(a)] are linked to adverse cardiovascular events. The significance of Lp(a) for the survival of octogenarians with coronary artery disease (CAD) after drug-eluting stent (DES) insertion is, however, not known. The purpose of the study is to investigated the connection between Lp(a) and outcome in octogenarians with CAD after DES implantation., Methods: We retrospectively enrolled a total of 506 consecutive octogenarians with CAD and DES implantation in our institution between January 2015 to August 2018. Two patient groups were established: a low group with plasma Lp(a) lower than 50 mg/dL (n = 408) and a high group with values above 50 mg/dL (n = 98)., Results: After following up for a median of 31.53 ± 8.22 months, Kaplan-Meier curves indicated that poorer outcome censored for major cardiovascular events (MACE), myocardial infarction (MI), and target vessel revascularization (TVR) in the high group relative to the low group (log-rank test p = 0.001, p = 0.008, and p < 0.001, respectively). High Lp(a) independently predicted MACE (hazard ratio (HR) 1.90; 95% confidence interval (CI) 1.28-2.84; p = 0.002), MI (HR 2.74; 95% CI 1.23-6.11; p = 0.014), and TVR (HR 3.65; 95% CI 1.99-6.69; p < 0.001) after covariate adjustment., Conclusions: High Lp(a) was also significantly related to poor long-term outcome in octogenarians with CAD after DES implantation., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).
