Dyslipidemias are a group of diseases, which are characterized by abnormal blood concentrations of cholesterol, triglycerides and/or low-density lipoprotein-cholesterol (LDL-c). Dyslipidemia is a determinant condition for the progress of an atherosclerotic plaque formation. The resulting atherogenicity is due to at least two mechanisms: first, to the accumulation in the plasma of lipid particles that have the capacity to alter the function of the endothelium and deposit at the atheromatous plaque, and second, at an insufficient concentration of multifactorial type of high density lipoprotein-cholesterol (HDL-c), whose function is to protect against the development of atherosclerosis. Its highest prevalence is encountered among individuals with diabetes, hypertension or overweight. Hyperlipidemia is one of the main predisposing factors for the development of cardiovascular disease. Hyperlipidemia can be the result of a genetic condition, the secondary expression of a primary process or the consequence of exogenous factors (food, cultural, socio-economic, .), all of which lead to the elevation of plasma lipid levels. The objective of this study was to carry out an analysis of the genes involved in the development of dyslipidemias that lead to cardiovascular disease with special emphasis on the proprotein convertase subtilin/kexin type 9 () gene. The gene participates in the development of primary dyslipidemias, mainly familial hypercholesterolemia, currently the pharmacological treatment of choice to reduce LDL-c are statins, however, it has been observed that these have been insufficient to eliminate cardiovascular risk, especially in subjects with primary forms of hypercholesterolemia related to genetic mutations, or statin intolerance.
血脂异常是一组疾病,其特征是血液中胆固醇、甘油三酯和/或低密度脂蛋白胆固醇(LDL-c)浓度异常。血脂异常是动脉粥样硬化斑块形成进展的决定性条件。由此产生的致动脉粥样硬化性至少归因于两种机制:第一,血浆中具有改变内皮功能并沉积在动脉粥样斑块能力的脂质颗粒的积累;第二,多因素类型的高密度脂蛋白胆固醇(HDL-c)浓度不足,其功能是预防动脉粥样硬化的发展。在糖尿病、高血压或超重个体中其患病率最高。高脂血症是心血管疾病发展的主要诱发因素之一。高脂血症可能是遗传状况的结果、原发性疾病的继发性表现或外源性因素(饮食、文化、社会经济等)的后果,所有这些都会导致血浆脂质水平升高。本研究的目的是对导致心血管疾病的血脂异常发展过程中涉及的基因进行分析,特别强调前蛋白转化酶枯草杆菌蛋白酶/kexin 9型()基因。该基因参与原发性血脂异常的发展,主要是家族性高胆固醇血症,目前降低LDL-c的药物治疗选择是他汀类药物,然而,已经观察到这些药物不足以消除心血管风险,特别是在与基因突变相关的原发性高胆固醇血症患者或他汀类药物不耐受的患者中。
