概括
在患有慢性病 (CKD) 的患者中,异常的心肌工作指数,特别是浪费工作 (GWW) 和工作效率 (GWE),与主要不良心血管事件 (MACE) 相关,主要是心力衰竭 (HF).
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 患有慢性病 (CKD) 的患者面临心血管 (CV) 事件的风险增加.
- 心肌工作指数为左心室 (LV) 功能异常提供了新的心声回声分析见解.
研究的目的:
- 调查心肌工作指数与慢性脏病患者主要心血管不良事件 (MACE) 之间的关联.
- 确定全球工作指数 (GWI),建设性工作 (GCW),浪费工作 (GWW) 和工作效率 (GWE) 等特定指数是否预测MACE.
主要方法:
- 以压力-应变循环分析进行前性心声学,以测量CKD患者的心肌工作指数.
- 考克斯回归和竞争风险回归分析被用来评估心肌工作指数和MACE之间的关联,占所有原因死亡.
主要成果:
- 在697名CKD患者中,42人 (6%) 在随访期间经历了MACE.
- 最初,所有心肌工作指数与MACE相关. 在调整后,GCW,GWW和GWE仍然是相关的.
- 在竞争风险回归中,只有GWW和GWE与MACE显著相关,主要是由心力衰竭 (HF) 而不是缺血性心脏病驱动的.
结论:
- 浪费工作 (GWW) 和工作效率 (GWE) 是MACE在非透析依赖性CKD患者中的独立预测因素.
- 这些心肌工作指数与MACE的关联主要与心力衰竭的发展有关.

283
Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

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 (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...

01:25Chronic Kidney Disease I: Introduction
531
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...

01:22Heart Failure Drugs: Diuretics
763
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

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...
