Pooled analysis revealed that elevated Lp(a) levels were significantly associated with increased risk of MACE (HR: 1.31, 95% CI: 1.19-1.45), all-cause mortality (HR: 1.23, 95% CI: 1.15-1.31), myocardial infarction (HR: 1.20, 95% CI: 1.06-1.35), and revascularization (HR: 1.23, 95% CI: 1.08-1.39) in IHD patients. The gene discussed is LPA; the disease is myocardial infarction.
