在冠状动脉扫描之后,远程缺血预调可以预防急性损伤:BRICK随机临床试验
在PubMed上查看摘要
概括
此摘要是机器生成的。在接受冠状动脉扫描的高风险患者中,远程缺血预调 (RIPC) 显著降低了急性损伤 (AKI) 和重大心血管和脑血管不良事件 (MACCE).
科学领域
- 心脏病学
- 肝脏病学
- 医疗干预
背景情况
- 接受侵袭性冠状动脉造影的患者面临急性损伤 (AKI) 的风险增加.
- 目前还没有确定的预防疗法来预防对比引起的病.
- 高风险人群需要有效的策略来缓解程序性并发症.
研究的目的
- 评估远程缺血预调剂 (RIPC) 在预防 AKI 的有效性.
- 评估RIPC对血管和尿路生物标志物的影响.
- 确定RIPC对主要心血管,脑血管和脏不良事件的影响.
主要方法
- 一个随机模拟对照试验,涉及接受冠状动脉扫描的高风险患者.
- 在1:1的比例下,患者被分配到RIPC或假RIPC.
- 主要结局是AKI的发生率;次要结局包括6个月后的生物标志物变化和不良事件.
主要成果
- 与假RIPC相比,RIPC显示了AKI率的显著降低 (14. 8% vs 29. 1%,P=0. 030).
- 在假血管组中,AKI的尿路生物标志物 (TIMP- 2/ IGFBP- 7) 增加,但在RIPC组中没有增加.
- 在6个月后,RIPC降低了主要心血管和脑血管不良事件 (MACCE) 的发生率 (16. 7% vs 36. 4%,P=0. 029).
结论
- 在接受冠状动脉扫描的高风险患者中,远程缺血预调是有效的减少AKI的发生率.
- 在该患者群体中,RIPC也对减少MACCE产生了有益影响.
- 这些发现表明RIPC对损伤生物标志物和临床结果有积极的影响.

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...
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
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...
