Assessment of voluntary rhythmic muscle contraction-induced exercising blood flow variability measured by Doppler ultrasound

引用

Open Journal of Molecular and Integrative Physiology 2013年第4期3卷 158-165页

作者： Takuya Osada Bengt Saltin Goran Radegran Department of Sports Medicine for Health Promotion Tokyo Medical UniversityTokyoJapan The Copenhagen Muscle Research Centre RigshospitaletUniversity of CopenhagenCopenhagenDenmark the clinic for heart failure and valvular disease Skane University HospitalLundSweden Department of Cardiology Clinical SciencesLund UniversityLundSweden

Given recent technological developments, ultrasound Doppler can provide valuable measurements of blood velocity/flow in the conduit artery with high temporal resolution. In human-applied science such as exercise physiology, hemodynamic measurements in the conduit artery is commonly performed by blood flow feeding the exercising muscle, as the increase in oxygen uptake (calculated as a product of arterial blood flow to the exercising limb and the arterio-venous oxygen difference) is directly proportional to the work performed. The increased oxygen demand with physical activity is met through a central mechanism, an increase in cardiac output and blood pressure, as well as a peripheral mechanism, an increase in vascular conductance and oxygen extraction (a major part of the whole exercising muscles) from the blood. The increase in exercising muscle blood flow in relation to the target workload (quantitative response) may be one indicator in circulatory adjustment for the ac- tivity of muscle metabolism. Therefore, the determination of local blood flow dynamics (potential oxygen supply) feeding repeated (rhythmic) muscle contractions can contribute to the understanding of the factors limiting work capacity including, for instance, muscle metabolism, substance utilization and magnitude of vasodilatation in the exercising muscle. Using non-invasive measures of pulsed Doppler ultrasound, the validity of blood velocity/flow in the forearm or lower limb conduit artery feeding to the muscle has been previously demonstrated during rhythmic muscle exercise. For the evaluation of exercising blood flow, not only muscle contraction induced internal physiological variability, or fluctuations in the magnitude of blood velocity due to spontaneous muscle contraction and relaxation induced changes in force curve intensity, superimposed in cardiac beat-by-beat, but also the alterations in the blood velocity (external variability) due to a temporary sudden change in the achieved workloa

目的心力衰竭是全球日益严重的主要公共卫生问题。护士主导的心力衰竭门诊在管理心力衰竭方面发挥着重要作用。该研究进行了一项系统综述,以描述护士主导心力衰竭门诊的内容及其影响。方法在PubMed、Embase、Web of Science和Cochrane Library中对护士主导心力衰竭门诊的研究进行了检索。检索最初于2022年10月23日进行,并于2023年11月21日进行更新。文章由两名独立研究者按照乔安娜-布里格斯研究所标准进行评估。本系统综述已在PROSPERO上注册(CRD42022352209)。结果共纳入12篇文献。护士主导心衰门诊的内容包括:药物滴定、教育咨询、基于循证的延续护理、社会心理支持、体格检查和心理健康评估、治疗监测和调整、随访和电话咨询。多数研究报告认为护士主导的心力衰竭门诊取得了积极的临床效果。4项研究对生活质量进行了调查,结果不一;4项研究对药物滴定的疗效进行了调查,结果总体上是积极的。仅2项研究对成本效果进行了评估,仍需更多相关研究进行验证。结论护士主导的心力衰竭门诊在很大程度上显示出对患者结局、生活质量、药物滴定效果的积极影响。

Measurement of the exercising blood flow during rhythmical muscle contractions assessed by Doppler ultrasound:Methodological considerations

Given the recent technological developments, ultra-sound Doppler can provide valuable measurements of arterial blood flow with high temporal resolution. In a clinical setting, measurements of hemodynamics is used to monitor, diagnose and manage changes in blood velocity profile for cardiac valve disease, relatively large vessel stenosis and other cardiovascular diseases. In health science and preventive medicine for cardiovascular disease with exercise therapy, evaluation of cardiac and vascular function is a useful indicator not only at rest but also during exercise, leading to improved exercise tolerance as well as physical activity. During exercise, the increase in oxygen uptake (calculated as product of arterial blood flow to the exercising limb and the arteriovenous oxygen difference) is directly proportional to the work performed. The increased oxygen demand is met through a central mechanism, an increase in cardiac output and blood pressure, as well as a peripheral mechanism, an increase in vascular conductance and oxygen extraction (major part in the whole exercising muscles) from the blood. Therefore, the determination of the local blood flow dynamics (potential oxygen supply) feeding to rhythmic muscle contractions can contribute to the understanding of the factors limiting the work capacity including, for instance the muscle metabolism, substance utilization and vasodilatation in the exercising muscle. Using non-invasive measures of pulsed Doppler ultrasound the validity of evaluating blood velocity/flow in the fore- arm or lower limb conduit artery feeding to the mus- cle is demonstrated during rhythmic muscle exercise;however the exercising blood velocity profile (fast Fourier transformation) due to muscle contractions is always seen as a physiological variability or fluctuations in the magnitude in blood velocity due to the spontaneous muscle contraction and relaxation induced changes in force curve intensity. Considering the above mentioned variation
