概括
增量穿步行测试 (ISWT) 有效地识别了无症状外周动脉疾病 (PAD) 患者的功能障碍,与六分钟步行测试 (6MWT) 不同. 在这个人群中,ISWT显示了步行能力的下降.
科学领域:
- 血管医学 血管医学
- 运动生理学 运动生理学
- 临床评估 临床评估
背景情况:
- 周围动脉疾病 (PAD) 影响血管健康和功能能力.
- 无症状的PAD是一个诊断挑战,因为个人可能不会表现出明显的症状.
- 标准步行测试,如6分钟步行测试 (6MWT) 和增量穿步行测试 (ISWT),用于评估功能能力.
研究的目的:
- 用6MWT和ISWT来比较患有和没有无症状PAD的个体的行走表现.
- 确定脚-手腕指数和脚-手腕指数 (ABI-TBI) 与无症状PAD患者的步行距离之间的相关性.
主要方法:
- 使用了横截面,交叉,匹配对的设计.
- 76名参与者 (38名无症状PAD,38名没有) 接受了6MWT和ISWT.
- 无症状的PAD是通过ABI-TBI测量来诊断的.
主要成果:
- 两组之间6分钟步行距离 (6MWD) 没有显著差异 (501.6m vs 516.8m,p=0.24).
- 患有无症状PAD的个体显著缩短了渐进式穿步行距离 (ISWD) (270m与340m相比,p=0.003).
- 在右腿脚-手臂指数 (TBI) 和ISWD (r=0.23,p=0.04) 之间观察到正相关性.
结论:
- ISWT,但不是6MWT,有效地揭示了无症状PAD患者的行走表现较差.
- 无症状的PAD与ISWT期间功能能力下降有关.
- 在无症状PAD中检测临床损伤时,ISWT可能是一个更敏感的工具.

Peripheral Artery Disease I: Introduction
659
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
764
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care
655
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Peripheral Artery Disease IV: Nursing Management
702
The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses,...
