背景情况:
- 之前的研究表明,糖尿病 (DM) 可能会对腹腔大动脉动脉瘤 (AAA) 和胸腔大动脉动脉瘤 (TAA) 提供保护.
- 潜在的保护机制和对患者结果的影响需要进一步研究.
研究的目的:
- 审查和综合最近关于糖尿病和大动脉动脉瘤之间的关系的文献.
- 评估DM对AAA和TAA发育,生长和患者死亡率的保护作用.
- 探索影响这种关系的潜在遗传和药理因素.
主要方法:
- 在PubMed和Cochrane数据库的系统文献搜索.
- 综合搜索术语:"大动脉动脉瘤"和"糖尿病".
- 对AAA,TAA和一般大动脉动脉瘤 (AA) 的相关证据进行了整理和总结.
主要成果:
- 患有DM的患者患上AAA的风险较低,增长速度较慢.
- 糖尿病与AAA住院后的死亡率降低有关,但AAA修复后的死亡率增加.
- 糖尿病药物梅特福林显示,AAA的生长,死亡率和并发症减少.
- 基因 *PSMD12* 正在研究其在AAA-DM连接中的作用.
- 对TAA来说,保护作用不那么一致,没有发现死亡率或并发症的显著差异.
结论:
- 糖尿病会对AAA的发展和破裂产生保护作用,可能由较厚的大动脉壁调解,从而降低张力.
- 甲胺在AAA患者中显示出显著的保护性质.
- 虽然DM可以防止AAA,但手术修复后的结果仍然令人担忧.

Coronary Artery Disease I: Introduction
57
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Aneurysm II: Clinical Manifestations and Diagnostic Studies
23
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm I: Introduction
25
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aneurysm III: Interprofessional Care
26
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Peripheral Artery Disease I: Introduction
33
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Diabetes: Symptoms, Diagnosis, and Complications
694
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...
