摘要
糖尿病显著增加动脉粥样硬化性心血管疾病(CVD)的风险。人力和
动物数据还表明,糖尿病阻止了循环中受损动脉的正常修复,
LDL胆固醇(LDL-C)降低。因此,糖尿病患者仍然有更大的风险,
即使他汀类药物降低LDL-C后,心血管事件的发生率也高于无糖尿病的个体。人士
糖尿病具有更大的血小板聚集、改变的白色血细胞和更多的血管炎症,
在未受影响的个体中,通过降低LDL-C改善病理过程。我们假设
确定T1 D患者对LDL-C降低的反应,我们将确定可以治疗靶向的途径,

1型糖尿病(T1 D)患者对LDL-C降低的反应。我们将从两个主要的

英文摘要
ABSTRACT
Diabetes markedly increases risk of development of atherosclerotic cardiovascular disease (CVD). Human and
animal data also show that diabetes prevents the normal repair of damaged arteries that occurs upon circulating
LDL cholesterol (LDL-C) reduction. Because of this, patients with diabetes still have greater risk of a
cardiovascular event even after statin reduction of LDL-C than individuals without diabetes. Individuals with
diabetes have greater platelet aggregation, altered white blood cells, and more vascular inflammation,
pathological processes that are improved by LDL-C reduction in unaffected individuals. We hypothesize that by
determining response to LDL-C reduction in T1D, we will identify pathways that can be therapeutically targeted
to optimize vascular repair and prevent CVD events. These data can also be used to determine patient
characteristics that associate with defective response to LDL-C reduction. We propose a clinical study of
response to LDL-C reduction in patients with Type 1 diabetes (T1D). We will recruit the patients from two major
medical centers, NYU Langone and Mount Sinai that serve diverse communities within New York City. Subjects
will be treated for 4 weeks with robust cholesterol-reducing therapies, PCSK9 inhibitors and also either statin
(80 mg atorvastatin) or ezetimibe (10 mg). Each subject will serve as their own control and we will determine
changes in platelets and white blood cells along with circulating inflammatory factors that occur when LDL-C is
markedly reduced. In a subgroup of subjects, changes in vascular inflammation will be determined by
assessment of harvested brachial vein endothelial cells and by uptake of 18F-fluordeoxyglucose into arteries. The
data will be analyzed by an experienced statistician with expertise in diabetes and CVD risk and will identify the
relationship of these changes with HbA1c and glucose variability, and differences between women and men. In
addition, the data in T1D will be compared with similar data assessing response to LDL-C in subjects with Type
2 diabetes and controls to determine abnormalities that differ between these two forms of diabetes.
