  10. Slide 10: LDL-P a robust predictor of cardiovascular risk

    LDL-P believed to be one of the most robust predictors of cardiovascular risk • Small dense LDL particles are more likely to be trapped in Low LDL-P confers a lower risk — arterial wall than larger-sized LDL particles even in patients with high LDL-C • High LDL-P levels typically signify that a pati
