概括
对降脂疗法的逐步方法成功帮助了84%的高风险患者通过口服药物实现LDL-C目标. 添加PCSK9抑制剂进一步改善了后急性冠状动脉综合征患者的结果.
科学领域:
- 心脏病学 心脏病学
- 药理学 药理学是指药理学的学科.
- 预防医学 预防医学
背景情况:
- 降低低密度脂蛋白胆固醇 (LDL-C) 对预防动脉样硬化心血管疾病 (ASCVD) 的二次预防至关重要.
- 许多患有动脉样硬化心血管疾病 (ASCVD) 的患者无法达到指南推的LDL-C目标.
- 2016年欧洲指南建议采取逐步的药物定位方法.
研究的目的:
- 评估在急性冠状动脉综合征 (ACS) 后患者中逐步降脂治疗策略的有效性.
- 评估仅使用口服药物达到LDL-C ≤1.8 mmol/l的患者比例.
- 通过升级治疗来确定LDL-C目标的总体成功率.
主要方法:
- 一项前性多中心非随机试验,涉及999名ACS后患者,先前患有ASCVD和/或糖尿病.
- 实施了三个步骤的策略: 1) 高强度他类药物 (HIST), 2) 添加ezetimibe, 3) 添加proprotein转化酶亚丁素/kexin类型9抑制剂 (PCSK9i).
- 每4-6周评估一次LDL-C水平,主要结局在第一步和第二步后LDL-C≤1.8 mmol/l.
主要成果:
- 84%的患者仅使用高强度他类药物和/或ezetimibe 达到≤1.8 mmol/l 的LDL-C 目标.
- 在对待意图的分析中,69%的患者在第一步后达到目标,84%在第二步后达到目标,87%在第三步后达到目标.
- 在每个相应的步骤中,在23,38和23名患者中发生了协议偏差.
结论:
- 通过逐步加强降脂疗法,在很高比例的非常高风险的ACS后患者中,有效地实现了LDL-C目标.
- 84%的患者使用口服药物 (他和/或ezetimibe) 达到≤1.8mmol/l的LDL-C目标.
- 添加PCSK9抑制剂进一步提高了成功率,达到87%.

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
