概括
对外围动脉疾病进行监督的跑步机炼显示,在12周后,步行有显著改善. 患者报告的行走能力在12周后得到改善,但在26周后没有持续.
科学领域:
- 心血管医学
- 运动生理学
- 康复科学
背景情况:
- 被监督的跑步机运动 (STE) 已知可以改善周围动脉疾病 (PAD) 患者的步行表现.
- 然而,即时的好处和实现有意义的改善的时间表尚未确定.
- 这项研究调查了6个月的PAD干预过程中步行距离的改善和患者报告的结果.
研究的目的:
- 在6个月的STE计划中,确定在6分钟步行距离 (6MWD) 中实现有意义的改善的时间.
- 通过走路障碍问卷 (WIQ) 的距离得分来评估患者报告的走路能力的有意义改善的时间进程.
- 在6个月内比较STE与非运动对照组对这些结果的影响.
主要方法:
- 一个随机对照试验涉及PAD参与者.
- 干预组接受监督的跑步机运动每周3次,持续6个月.
- 结果包括6MWD和WIQ距离得分,在6周,12周和26周测量.
主要成果:
- 与对照组相比,STE显著改善了6MWD,在12周后观察到有意义的增长 (31. 8m增加,P<0. 001).
- 第一次观察到WIQ距离得分有意义的改善是在12周 (+6. 59, P=0. 049),但这一好处在26周 (+2. 37, P=0. 49) 没有统计学意义.
- 在6MWD中获得大的有意义的收益需要超过6周的STE.
结论:
- 对于患有PAD的人来说,需要超过6周的STE才能实现6分钟步行距离的显著改善.
- 经过12周的STE,可以测量6MWD的显著增长.
- 虽然患者报告的行走能力在12周后初步显著改善,但这一效应在26周的随访期间没有持续.

29
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...

01:30Peripheral Artery Disease I: Introduction
32
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...

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,...

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...

01:20Exercise and Cardiovascular Response
1.1K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
