Randomized Controlled Trial Multicenter Study
Relationship Between Low-Density Lipoprotein Cholesterol, Free Proprotein Convertase Subtilisin/Kexin Type 9, and Alirocumab Levels After Different Lipid-Lowering Strategies.
Alirocumab undergoes target-mediated clearance via binding of proprotein convertase subtilisin/kexin type 9 (PCSK9). Statins increase PCSK9 levels; the effects of nonstatin lipid-lowering therapies are unclear. Every-4-weeks dosing of alirocumab may be appropriate for some patients in absence of background statin but is not yet approved. ⋯ URL: http://www.Clinicaltrials.gov. Unique identifier: NCT01723735.

The Brugada syndrome is an inherited cardiac arrhythmia associated with high risk of sudden death. Although 20% of patients with Brugada syndrome carry mutations in SCN5A, the molecular mechanisms underlying this condition are still largely unknown. ⋯ Altogether, our results indicate that Kvβ2 dysfunction can contribute to the Brugada electrocardiographic pattern.
