MONTANO-SOSA, M et al. Inhibition of PCSK9: a new alternative for cholesterol reduction and prevention of atherosclerotic cardiovascular disease. Med. interna Méx. [online]. 2017, vol.33, n.2, pp.226-237. ISSN 0186-4866.

Atherosclerotic cardiovascular disease represents the leading cause of morbidity and mortality in most countries. The main risk factor for developing this disease is low density lipoprotein cholesterol (LDL-C). The pharmacological treatment of choice for reducing LDL-C is statins; however, in spite of the widespread use of statins, these drugs have been insufficient to eliminate cardiovascular risk. This residual risk is most relevant in patients with primary forms of hypercholes-terolemia associated with genetic mutations, or in those who are intolerant to statins. The development of new drugs to reduce residual cardiovascular risk is of vital importance. Proprotein convertase subtilisin-kexin 9 (PCSK9) is an important regulator of the amount of LDL receptors since its function is to direct these receptors to their lysosomal destruction. The development of monoclonal antibodies to block extracellular PCSK9 has allowed us to improve the quantity and efficiency of LDL receptors, resulting in a significant decrease in plasma cholesterol. Efficacy and safety of these antibodies is currently considered acceptable and preliminary data are encouraging but still insufficient to assess the favorable impact of these antibodies in reducing cardiovascular morbidity and mortality.
