Abstract

Aims Controversy exists regarding benefits of raising HDL-C in statin-treated coronary artery disease (CAD) patients. We assessed the anti-atherosclerotic efficacy of raising HDL-C in statin-treated individuals with CAD across a range of achieved LDL-C, including lower (<70 mg/dL) versus higher (≥70 mg/dL) levels. Methods and results In seven prospective randomized trials utilizing serial coronary intravascular ultrasound, 3469 statin-treated CAD patients were stratified according to achieved LDL-C ( < 70 mg/dL, greater HDL-C-raising did not associate with disease progression/regression. In those with achieved LDL-C ≥ 70 mg/dL, greater HDL-C-raising associated with less disease progression (OR 0.80 (95% CI 0.67, 0.97)) and MACE (HR 0.78 (95% CI 0.64, 0.96)). Greater increases in HDL-C (up to 25% from baseline) across the continuous range of on-treatment LDL-C levels associated with less disease progression)OR 0.90 (95% CI 0.83, 0.98)) and lower MACE (HR 0.87 (95% CI 0.77, 0.998)). Conclusions Increasing HDL-C via a broad spectrum of mechanisms appears beneficial in statin-treated CAD patients, but is likely of greater benefit in patients with achieved LDL-C levels ≥70 mg/dL.
