概括
患有功能衰竭的患者在植入药物排泄支架 (DES) 后出现更高的静脉动脉样硬化 (ISNA) 和薄盖纤维动脉瘤 (TCFA) 发生率. 低估计的淋巴膜过率 (eGFR) 与增加的ISNA和不太稳定的新密度相关.
科学领域:
- 心血管医学 心血管医学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 生物医学工程 生物医学工程
背景情况:
- 药物排泄支架 (DES) 植入后的内置支架缩 (ISR) 是一个重大的临床挑战.
- 慢性病 (CKD) 在ISR和相关的新动脉样硬化的进展中的作用仍然不完全理解.
- 内置支架新动脉样硬化 (ISNA) 代表ISR的病态进展,其特征是富含脂质的斑块形成.
研究的目的:
- 为了研究慢性病 (CKD) 的不同程度与在DES植入后患有静脉静脉缩 (ISR) 患者的静脉静脉缩 (ISNA) 的患病率之间的关联.
- 评估估计的淋巴膜过率 (eGFR) 与ISR病变中的新内的特征之间的关系,包括薄盖纤维肌瘤 (TCFA) 的存在.
主要方法:
- 一组220名患者在DES植入后得到确认的ISR被追溯分析.
- 根据eGFR,患者被分为三组:正常 (≥90毫升/分钟/1.73米2),轻度损伤 (6089毫升/分钟/1.73米2) 和功能衰竭 (<60毫升/分钟/1.73米2).
- 光学连贯断层扫描 (OCT) 用于评估ISNA和TCFA在ISR病变中的情况. 收集了临床和血管学数据,并在各组之间进行了比较.
主要成果:
- 在三个eGFR组之间没有观察到基线血管学特征的显著差异.
- 衰竭组的患者表现出显著更高的ISNA率 (68.5%) 与轻度 (46.5%) 或正常 (42.5%) 功能 (p<0.05) 的患者相比.
- 在ISR病变中的TCFA发生率在功能衰竭组 (40.7%) 与轻度 (22.1%) 和正常 (22.5%) 功能组 (p<0.05) 相比也显着更高. 较低的eGFR与增加的ISNA和降低的neointima稳定性有关.
结论:
- 慢性病,特别是衰竭,在DES植入后患有静脉静止症 (ISR) 的患者中,独立地与更高的静脉动脉硬化症 (ISNA) 和薄盖纤维动脉瘤 (TCFA) 的患病率有关.
- 降低估计的淋巴膜过率 (eGFR) 可能表明ISR的背景下增加了neointimal不稳定性和更高的不良事件风险.
- 这些发现强调了在评估心血管风险和管理ISR后DES植入患者时考虑功能的重要性.

Chronic Kidney Disease II: Clinical Manifestations
104
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Chronic Kidney Disease I: Introduction
76
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Acute Kidney Injury II: Pathophysiology
97
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
