JACC:尽早控制LDL-C才是硬道理,研究显示LDL-C积累的时间进程与CVD事件的风险显著相关

2020-09-23 心关注 心关注

随着低密度脂蛋白胆固醇(LDL-C)浓度和暴露时间的增加,心血管疾病(CVD)的发病率也会增加。LDL-C与年龄曲线下的面积是一个可能的危险参数,目前尚没有基于数据证明该指标效用的直观方法。

随着低密度脂蛋白胆固醇(LDL-C)浓度和暴露时间的增加,血管疾病(CVD)的发病率也会增加。LDL-C与年龄曲线下的面积是一个可能的危险参数,目前尚没有基于数据证明该指标效用的直观方法,并且面积累积的时间过程是否可以调节风险尚不清楚。近日,发表在JACC上的一项研究使用来自CARDIA的数据,研究人员开发了一种同时纳入LDL-C与年龄曲线下面积及面积累积的时间进程两个因素的风险模型,结果显示LDL-C的累积暴露年限与CVD事件的风险显着相关,研究发现强调了早期控制LDL-C的重要性。

这项研究表明,在特定年龄发生CVD的风险随着LDL-C与年龄曲线下总累积面积的增加而增加。重要的是,这种风险是由面积积累的时间进程调节的。具体来说,数据表明,早期积累的面积比后来积累相同面积的风险更大。因此,举例来说,两个年龄在40岁,LDL-C和/或LDL-C与年龄曲线下相同面积的人,如果面积累积的时间进程不同,那么将来发生CVD的风险可能不同。

这就强调了在生命早期达到最佳LDL-C水平的重要性,因为在晚期LDL-C即使低到足以在一个标志性的年龄(如40岁)出现同一面积,也不能完全逆转早期获得的风险。因此评估未来CVD事件的风险不仅要考虑LDL-C与年龄曲线下的面积,还要考虑累积的时间进程。

在这项前瞻性分析中,研究人员纳入了从1985年到1986年参加CARDIA试验的4958名参与者(登记时的平均年龄25岁;55.3%的妇女;51%的黑人)。研究人员评估了LDL与年龄曲线下面积和CVD事件风险的关系,以及相同面积增加的风险在不同年龄是否不同。主要结果是非致命性冠心病、卒中、短暂性脑缺血发作、心衰住院、心脏血运重建、外周动脉疾病干预或CV死亡。

40岁之后的平均16年随访期间,那些在40岁之前没有CVD事件的患者中,有275名参与者发生了第一次CVD事件。首次发生CVD事件的中位年龄为49岁。50岁时CVD事件发生率为3.1%,60岁时增加到7.8%。

研究人员观察到,在调整性别、种族和危险因素后,LDL与年龄曲线下的面积(每100 mg/dL×年,HR=1.053;P<0.0001)和面积累积的时间进程(每mg/dL/年,HR = 0.797;P=0.045)与CVD事件风险显着相关。

年轻健康成年人的低强度治疗

美国维克森林大学医学院心血管疾病预防中心主任Michael D. Shapiro教授和布列根和妇女医院心血管介入项目执行主任、哈佛医学院医学教授Deepak L.Bhatt在随刊发表的一篇社论中表示,尽管仍有一些问题没有得到解答,但最重要的问题也许是需要更多的证据来建议对高胆固醇血症的年轻人进行长期的降脂治疗。我们的社会是否也愿意在大范围的年轻健康个体中开始低强度治疗,即使有力的随机试验证据不支持这种方法?这项研究的胆固醇-年模型使我们离这种可能又近了一步。
