Association between Lipoprotein(a) concentration and adverse cardiac events in patients with coronary artery disease: An observational cohort study.

This prospective study investigated the association between lipoprotein (a) [Lp(a)] levels and adverse cardiac events in patients undergoing percutaneous coronary intervention (PCI) for coronary artery disease. Among 600 patients, 79.16 % were male. Kaplan Meier analysis revealed significantly higher incidence rates of cardiac death, major adverse cardiac events, myocardial infarction, revascularization and stroke in patients with elevated Lp(a) (≥30 mg/dL). The Cox Regression model identified Lp(a) ≥30 mg/dL as a significant risk factor for adverse events (HR: 4.2920; 95%CI: 2.58-7.120; p < 0.05). Elevated Lp(a) levels were associated with an increased risk of adverse cardiac events in coronary artery disease patients undergoing PCI.
