Guidelines for managing patients with atherosclerotic cardiovascular disease (ASCVD) recommend statin therapy initially. Target levels/goals for low-density lipoprotein-cholesterol (LDL-C) were initially included, subsequently de-emphasized in 2013, and then re-introduced as thresholds, leading to confusion in clinical practice. We designed a multicenter, observational registry of patients with ASCVD, to describe and track LDL-C treatment patterns in the United States over time.
Patients with ASCVD receiving any pharmacologic lipid-lowering therapy were eligible for enrollment in one of three cohorts: 1) currently receiving a proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i), or not receiving PCSK9i with 2) LDL-C 70-99 mg/dL, or 3) LDL-C ≥100 mg/dL. Patients undergo a 1-year retrospective chart review, followed by chart reviews and phone interviews every 6 months for 2 years.
A total of 5006 patients were enrolled at 119 centers. Mean age was 68 years, 40% of patients were female, 86% were white, 80% had coronary artery disease, and 33% had type 2 diabetes mellitus. Among those not on a PCSK9i, high-intensity statins and ezetimibe were utilized in only 44% and 9%, respectively. Among women vs men, only 36.6% vs 48.2% received high-intensity statins (P < .001). Among patients on a PCSK9i, only one-third were receiving a statin, suggesting statin intolerance is a driver of PCSK9i use at present.
Our data on current practice in the US continue to illustrate that high-intensity statins and ezetimibe are underutilized in at-risk patients outside of clinical trials, particularly women. This study will track temporal changes in treatment patterns and identify opportunities for improvement in lipid management in patients with ASCVD.
管理动脉粥样硬化性心血管疾病(ASCVD)患者的指南最初推荐使用他汀类药物治疗。最初包括了低密度脂蛋白胆固醇(LDL-C)的目标水平/目标,但在 2013 年被淡化,然后重新作为阈值引入,导致临床实践中的混淆。我们设计了一项多中心、观察性的 ASCVD 患者注册研究,以描述和跟踪美国随时间推移 LDL-C 治疗模式的变化。
正在接受任何药物降脂治疗的 ASCVD 患者有资格入组三个队列之一:1)正在接受前蛋白转化酶枯草溶菌素/糜蛋白酶 9 抑制剂(PCSK9i)治疗,或未接受 PCSK9i 治疗且 LDL-C 为 70-99mg/dL,或 2)LDL-C≥100mg/dL。患者接受为期 1 年的回顾性病历审查,随后每 6 个月进行 2 年的病历审查和电话访谈。
共有 5006 名患者在 119 个中心入组。平均年龄为 68 岁,40%的患者为女性,86%为白人,80%患有冠状动脉疾病,33%患有 2 型糖尿病。在未接受 PCSK9i 治疗的患者中,高强度他汀类药物和依折麦布的使用率分别仅为 44%和 9%。在女性与男性之间,只有 36.6%与 48.2%接受了高强度他汀类药物治疗(P<0.001)。在接受 PCSK9i 治疗的患者中,只有三分之一在服用他汀类药物,这表明他汀类药物不耐受是目前使用 PCSK9i 的驱动因素。
我们在美国的当前实践数据继续表明,高强度他汀类药物和依折麦布在临床试验之外的高危患者中使用不足,特别是女性。这项研究将跟踪治疗模式的时间变化,并确定改善 ASCVD 患者脂质管理的机会。
