Niacin (nicotinic acid) is the most effective agent for raising high-density lipoprotein cholesterol levels and can improve the entire lipid panel in patients with dyslipidemia. Niacin-containing regimens are among the few treatments studied for dyslipidemia that have both elicited significant reductions in atherosclerotic progression (by angiography or imaging) and also significantly reduced (by approximately 90% vs control) the incidence of cardiovascular events in a single clinical trial. However, cutaneous flushing-an uncomfortable but typically transient adverse effect of niacin-often results in patient nonadherence with this potentially life-saving therapy. Effective counseling regarding the highly favorable benefit-risk ratio for niacin and management strategies such as careful dose escalation, follow-up monitoring, regimen adjustments, and the use of treatment adjuncts (eg, aspirin) can improve patient adherence with niacin therapy. Clinicians are uniquely positioned to provide such counseling to appropriate patients for niacin treatment and hence encourage wider use of this important and necessary cardioprotective medication.
烟酸(烟碱酸)是提高高密度脂蛋白胆固醇水平最有效的药物,可改善血脂异常患者的整个血脂谱。在血脂异常的少数几种研究治疗方法中,烟酸类药物既能显著减少动脉粥样硬化进展(通过血管造影或影像学检查),又能显著降低(与对照组相比降低约 90%)心血管事件的发生率,这在一项临床试验中得到了证实。然而,烟酸会引起皮肤潮红——一种令人不适但通常是短暂的不良反应——导致患者不依从这种潜在的救命治疗。对烟酸的高度有利风险比进行有效的咨询,并采取管理策略,如谨慎地增加剂量、随访监测、调整治疗方案以及使用治疗辅助药物(如阿司匹林),可以提高患者对烟酸治疗的依从性。临床医生在为适当的患者提供烟酸治疗方面具有独特的优势,因此鼓励更广泛地使用这种重要且必要的心脏保护药物。
