概括

高的LDL-C水平显著增加了患有2型糖尿病 (T2DM) 无症状患者冠状动脉化 (CAC) 的风险. 这一发现表明,LDL-C是对这一群体心血管风险分层的一个有价值的工具.

科学领域:

心脏病学心脏病学
内分泌学在内分泌学.
预防医学预防医学

背景情况:

冠状动脉化 (CAC) 是心血管疾病的一个关键风险因素.
升高的低密度脂蛋白胆固醇 (LDL-C) 在2型糖尿病 (T2DM) 中很常见,并与动脉样硬化有关.
在无症状T2DM患者中,LDL-C水平和新发病的CAC之间的关系需要进一步调查.

研究的目的:

调查LDL-C基线水平与无症状T2DM患者中CAC发病率之间的关联.
为了确定LDL-C是否可以作为该特定患者群体中发生CAC的预测因素.

主要方法:

一个单一中心的回顾性队列研究包括2631名无症状T2DM患者,最初没有CAC.
根据基线LDL-C水平,参与者被分为三组.
卡普兰-梅尔曲线,日志级别测试和考克斯比例危险回归模型被用于分析CAC的发病率,平均随访时间为29.9个月.

主要成果:

观察到新的CAC的大量累积发病率,随着较高的LDL-C水平而增加 (P < 0.001).
多变量分析显示,LDL-C和发生的CAC之间存在强烈的关联 (调整HR,1.77;95%CI,1.64-1.92).
中等和最高三角动物的LDL-C升高与增加的CAC风险显著相关 (调整后HRs分别为1.62和3.38).

结论:

较高的LDL-C水平与无症状T2DM患者发生的CAC的发展有显著的关联.
LDL-C水平可能是T2DM患者心血管风险分层的一个有价值的生物标志物.
进一步的研究可以探索有针对性的LDL-C降低策略,以预防该群体的CAC.

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Carbohydrate Metabolism

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Blood Studies for Cardiovascular System III: Serum Lipid Profile

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...

Cholesterol: Significance and Regulation

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
