Novel Lipoproteins, Cardiometabolic Risk, and Statin Therapy

描述（由申请人提供）：候选人Samia莫拉，医学博士，MHS，是哈佛医学院布里格姆妇女医院预防和心血管医学系的医学助理教授。她接受过心血管医学培训并获得认证，并拥有约翰霍普金斯彭博公共卫生学院流行病学硕士学位。她的长期职业目标是成为心血管疾病（CVD）预防和流行病学领域的领导者。为了实现这一目标，她制定了一个基于导师的研究职业发展计划，提供培训，以实现3个短期目标：1）获得对脂质和脂蛋白风险因素，心脏代谢疾病和女性健康的理解和能力，2）获得设计，管理和解释大型前瞻性研究和临床试验所需的经验和技能，及3）发展专业及职业发展的领导技巧。目前的预防指南建议测量标准脂质以评估CVD风险，并将LDL胆固醇降低作为治疗的主要目标。这些指南不建议常规测量新的脂蛋白，因为目前还不清楚它们是否有助于标准脂质测量以外的CVD风险信息。这项研究提案的中心目标是确定新型脂蛋白是否比标准脂质更好地衡量心血管疾病和2型糖尿病的一级预防的心脏代谢风险。我们建议进行一项全面的研究，新的脂蛋白（免疫测定法测量的载脂蛋白和核磁共振测量的脂蛋白）的事件CVD和2型糖尿病在明显健康的个人和代谢综合征，与和不使用他汀类药物治疗。特异性目标1测试新型脂蛋白在预测CVD和2型糖尿病事件中的相关性。特定目标2测试新的脂蛋白是否增加了与CVD和2型糖尿病风险相关的代谢综合征的定义。特定目标3检查了他汀类药物治疗引起的新型脂蛋白的变化及其与代谢综合征患者和非代谢综合征患者CVD风险降低的相关性。相关性（参见说明）：尽管心血管疾病和2型糖尿病的负担很大，但根据目前依赖标准血脂检测的指南，约有1.4亿无症状的美国成年人被归类为低风险。在大量无症状成人中，对更好的风险评估和具有成本效益的治疗的需求尚未得到满足。新的脂蛋白可以促进CVD和代谢疾病的风险检测和治疗。

DESCRIPTION (provided by applicant): The candidate, Samia Mora, MD, MHS, is an Assistant Professor of Medicine in the Divisions of Preventive and Cardiovascular Medicine at the Brigham and Women's Hospital, Harvard Medical School. She is trained and certified in Cardiovascular Medicine and has an MHS in Epidemiology from the Johns Hopkins Bloomberg School of Public Health. Her long-term career goal is to become a leader in the field of cardiovascular disease (CVD) prevention and epidemiology. To realize this goal, she has developed a mentor-based research career development plan which provides training to achieve 3 short-term goals: 1) to gain understanding and competence in lipid and lipoprotein risk factors, cardiometabolic disorders, and women's health, 2) to gain experience and skills necessary to design, manage, and interpret large prospective studies and clinical trials, and 3) to develop professional and career-building leadership skills. Current prevention guidelines recommend measurement of standard lipids to assess CVD risk and focus on LDL cholesterol lowering as the primary target of therapy. These guidelines do not recommend the routine measurement of novel lipoproteins since it is unclear whether they contribute CVD risk information beyond standard lipid measurements. The central goal of this research proposal is to ascertain whether novel lipoproteins are better measures of cardiometabolic risk than standard lipids for the primary prevention of CVD and type 2 diabetes. We propose to conduct a comprehensive study of novel lipoproteins (immunoassay-measured apolipoproteins and nuclear magnetic resonance-measured lipoproteins) in relation to incident CVD and type 2 diabetes in apparently healthy individuals and those with the metabolic syndrome, with and without statin therapy. Specific Aim 1 tests the association of novel lipoproteins in predicting incident CVD and type 2 diabetes. Specific Aim 2 tests whether novel lipoproteins add to the definition of the metabolic syndrome in relation to risk of CVD and type 2 diabetes. Specific Aim 3 examines changes in novel lipoproteins that result from statin therapy and their association with CVD risk reduction in individuals with and without the metabolic syndrome. RELEVANCE (See instructions): Despite the extensive burden of CVD and type 2 diabetes, approximately 140 million asymptomatic US adults are classified as low risk by current guidelines that rely on standard lipid tests. There is an unmet need for better risk assessment and cost-effective therapies in this large number of asymptomatic adults. Novel lipoproteins may advance risk detection and therapies for CVD and metabolic diseases.
