Overt atherosclerotic cardiovascular disease (ASCVD) warrants aggressive lipid lowering. Imaging for ambiguous symptoms suggesting ischemia or for clarification of CV risk in asymptomatic individuals often uncovers previously unknown ASCVD. Guidelines do not provide clear recommendations for aggressive lipid lowering in such cases. We explored physicians' perception, as influenced by tests that detect ASCVD, regarding appropriateness of getting to lipid goals and for theoretically accessing proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i).
A questionnaire was developed including cases of low to high CV risk, chronic kidney disease (CKD) or type 2 diabetes mellitus (T2DM). Each case was considered with or without angina symptoms and, in turn, whether testing identified previously unknown advanced, early/subclinical or no ASCVD. Synthesis of responses was facilitated by using a scale for perceived appropriateness from 1 (lowest) to 9 (highest).
Getting to goal and, if not achieved by statins and/or ezetimibe, accessing PCSK9i was considered appropriate in patients with T2DM with preclinical or advanced ASCVD, patients with moderate or high CV risk and advanced ASCVD, patients with CKD or low CV risk with angina symptoms and advanced ASCVD. For most of the remaining cases adding PCSK9i was considered only possibly appropriate.
Physicians' perception of appropriateness for achieving lipid goals, including access to PCSK9i, is markedly influenced by detection of previously unknown ASCVD. Since these commonly encountered scenarios do not clearly meet current indications for PCSK9i, our data identify pressing areas requiring further research.
明显的动脉粥样硬化性心血管疾病(ASCVD)需要积极降脂。对于提示缺血的模糊症状或为明确无症状个体的心血管风险进行影像学检查,通常会发现先前未知的 ASCVD。指南并未针对此类情况提供积极降脂的明确建议。我们探讨了医生的看法,这些看法受检测 ASCVD 的检测的影响,了解达到降脂目标和理论上使用前蛋白转化酶枯草溶菌素 9 抑制剂(PCSK9i)的适宜性。
开发了一份调查问卷,包括低至高心血管风险、慢性肾脏病(CKD)或 2 型糖尿病(T2DM)的病例。每个病例均考虑有或无心绞痛症状,并且依次考虑检测是否确定了先前未知的晚期、早期/亚临床或无 ASCVD。通过使用从 1(最低)到 9(最高)的感知适宜性量表,促进了对响应的综合。
在有临床前或晚期 ASCVD 的 T2DM 患者、有中重度或高心血管风险和晚期 ASCVD 的患者、有 CKD 或低心血管风险伴心绞痛症状和晚期 ASCVD 的患者中,达到目标值,如果他汀类药物和/或依折麦布不能达到目标值,则使用 PCSK9i 被认为是合适的。对于大多数其余病例,添加 PCSK9i 仅被认为可能合适。
医生对实现降脂目标的适宜性的看法,包括对 PCSK9i 的使用,受到先前未知的 ASCVD 的显著影响。由于这些常见的情况并未明确符合当前 PCSK9i 的适应症,我们的数据确定了迫切需要进一步研究的领域。
