Abstract

Background: Patients with a history of coronary revascularization are at a higher risk for subsequent cardiovascular events and all-cause mortality. Lowering LDL-cholesterol (LDL-C) levels post-revascularization significantly reduces these risks.

Methods: This analysis compared LDL-C-lowering therapies at baseline and over time among patients with and without prior coronary revascularization in the GOULD registry (a prospective multicenter cohort study). Baseline- and 24-month follow-up characteristics-including LDL-C levels and strategies for lipid-lowering therapy (LLT)-were evaluated.

Results: Out of 5006 patients, 2195 (43.8%) had prior coronary revascularization. At baseline, these patients had lower LDL-C (99.2 mg/dL vs. 102.5 mg/dL; p < 0.001) and were more likely to be on intensive LLT (52.8% vs. 42.7%; p < 0.001). At 24 months, they had small reductions in LDL-C (-15.6% vs. -13.7%; p = 0.145) and were more likely to be on intensive LLT (61.9% vs. 51.5%; p < 0.001). Similar LDL-C reductions were observed in the PCSK9i group regardless of revascularization status.

Conclusions: Despite slightly better baseline LLT among patients with prior revascularization, few patients met the <70 mg/dL goal and LLT was rarely escalated during 24 months of follow-up. Improved systems-based strategies and personalized treatment approaches are urgently needed to enhance LDL-C lowering and reduce cardiovascular events, especially in patients with a history of coronary revascularization.
