Total & CV Mortality After LDL-C Lowering

JAMA; 2018 Apr 17; Navarese, et al

The greatest benefit from low-density lipoprotein cholesterol (LDL-C) lowering therapy may occur for patients with higher baseline LDL-C levels, a recent study found. The systematic review and meta-analysis included 34 trials in which 136,299 patients received more intensive and 133,989 received less intensive LDL-C lowering. The trials included therapy with statins, ezetimibe, and PCSK-9 inhibiting monoclonal antibodies. Researchers evaluated whether baseline LDL-C level is associated with total and cardiovascular (CV) mortality risk reductions. They found:

  • More intensive compared with less intensive LDL-C lowering was associated with a greater reduction in risk of total mortality in patients with higher baseline LDL-C levels.
  • However, this relationship was not present with baseline LDL-C levels of ≥100 mg/dL.
  • There was a similar relationship for CV mortality.
