Despite issues about the value of statins, benefit for high cardiovascular (CV) risk outweighs problems. However, the practitioner must be aware of concerns, be prepared to respond, and justify statin usage. Symptoms of statin-related myopathy are of more concern than stated by pharmaceutical companies. Occurrence of myopathy symptoms, estimated to be up to 10.4%, can decrease statin adherence of high CV risk patients. Dosage modification, or use of pitavastatin, may help the problematic patient. There are concerns that there may be little benefit of statins for primary prevention in women. However, evidence appears to support statin use in women at high CV risk, both in primary and secondary prevention. Abandoning low-density lipoprotein cholesterol (LDL-C) as a valid target is unwarranted; there is much evidence to support "lower is better." The practitioner must be aware of the complicated processes causing atherosclerosis and when to incorporate new approaches to disease management. Tailoring therapy for CV risk, when indicated, may contribute further to LDL-C reduction. Liver inflammation can occur with statins but is of minimal concern; frequently, statins alleviate the problem. Unless liver transaminases are over three times normal, a statin should be prescribed, if indicated. The net effect of statins on cognition appears to be zero-no harm, no benefit. Despite reports of improved cognition, statins should not be prescribed for this. With diabetes mellitus (DM), statins can increase incidence, but the CV benefit far outweighs any risk. Therefore, statins should be prescribed in DM to reduce CV risk. Statins are a major medical contribution when used appropriately.
尽管他汀类药物存在价值方面的问题,但对心血管(CV)高风险人群的益处大于问题。然而,从业者必须了解相关问题,做好应对准备,并为他汀类药物的使用提供合理依据。他汀类药物相关肌病的症状比制药公司所宣称的更值得关注。肌病症状的发生率估计高达10.4%,这可能会降低心血管高风险患者对他汀类药物的依从性。调整剂量或使用匹伐他汀可能有助于解决问题患者的情况。有人担心他汀类药物对女性一级预防可能益处不大。然而,证据似乎支持在一级和二级预防中,对心血管高风险女性使用他汀类药物。放弃将低密度脂蛋白胆固醇(LDL-C)作为有效治疗目标是没有道理的;有大量证据支持“越低越好”。从业者必须了解导致动脉粥样硬化的复杂过程以及何时采用新的疾病管理方法。在有指征时,根据心血管风险调整治疗方案可能有助于进一步降低LDL-C水平。他汀类药物可能会引发肝脏炎症,但无需过度担忧;通常情况下,他汀类药物会缓解这一问题。除非肝转氨酶超过正常水平的三倍,如有指征,仍应开具他汀类药物处方。他汀类药物对认知的总体影响似乎为零——既无危害也无益处。尽管有报道称认知功能有所改善,但不应为此开具他汀类药物。对于糖尿病(DM)患者,他汀类药物可能会增加发病率,但心血管益处远大于任何风险。因此,糖尿病患者应使用他汀类药物以降低心血管风险。他汀类药物在合理使用时是一项重大的医学贡献。
