AbstractThe article deals with the design of an electrical model of variable segments of a non-symmetrical tree of small arteries This model can be used to simulate the blood pressure and flow. Peripheral arterial resistance changes are modelled by an exponentially dependent resistor. By modulating the capacitor value, we can model the arterial wall properties which depend on the arterial pressure. Simulations are performed in which vasoconstriction and vasodilation were modelled by varying the transmural pressure. As a result, we can observe the changes in the blood pressure for each arterial generation.

Advantage has been taken of the relative transparency of the claw of the mouse to devise a method, here described, to measure the blood pressure in the animal's leg. Direct measurements of the systolic blood pressure from the carotid arteries of anesthetized mice have also been made. Simultaneous blood pressure readings by both these methods applied to the same animal showed close agreement. The systolic pressure ranged from 60 to 126 mm. Hg, according to the conditions.

Hot Water Immersion

Passive heat induces beneficial perfusion profiles, provides substantive cardiovascular strain, and reduces blood pressure, thereby holding potential for healthy and cardiovascular disease populations. The aim of this study was to assess acute responses to passive heat via lower-limb, hot-water immersion in patients with peripheral arterial disease (PAD) and healthy, elderly controls. Eleven patients with PAD (age 71 ± 6 yr, 7 male, 4 female) and 10 controls (age 72 ± 7 yr, 8 male, 2 female) underwent hot-water immersion (30-min waist-level immersion in 42.1 ± 0.6°C water). Before, during, and following immersion, brachial and popliteal artery diameter, blood flow, and shear stress were assessed using duplex ultrasound. Lower-limb perfusion was measured also using venous occlusion plethysmography and near-infrared spectroscopy. During immersion, shear rate increased ( P < 0.0001) comparably between groups in the popliteal artery (controls: +183 ± 26%; PAD: +258 ± 54%) and brachial artery (controls: +117 ± 24%; PAD: +107 ± 32%). Lower-limb blood flow increased significantly in both groups, as measured from duplex ultrasound (>200%), plethysmography (>100%), and spectroscopy, while central and peripheral pulse-wave velocity decreased in both groups. Mean arterial blood pressure was reduced by 22 ± 9 mmHg (main effect P < 0.0001, interaction P = 0.60) during immersion, and remained 7 ± 7 mmHg lower 3 h afterward. In PAD, popliteal shear profiles and claudication both compared favorably with those measured immediately following symptom-limited walking. A 30-min hot-water immersion is a practical means of delivering heat therapy to PAD patients and healthy, elderly individuals to induce appreciable systemic (chronotropic and blood pressure lowering) and hemodynamic (upper and lower-limb perfusion and shear rate increases) responses.

Background/Aims Peripheral arterial disease is common among those aged 60 years or above and can cause debilitating intermittent claudication. This impacts quality of life and is a marker for increased morbidity and mortality, mainly from cardiovascular disease. Access to recommended exercise programmes for people with symptomatic peripheral arterial disease is poor in most areas of the UK. This study aimed to evaluate the benefits of expanding an established cardiac rehabilitation service to accommodate supervised exercise for people with peripheral arterial disease Methods The study evaluated 11 participants peripheral arterial disease and intermittent claudication who were referred by the Manchester leg circulation service. Participants underwent the programme involving eight weekly 1.5 hour sessions of supervised exercise and cardiovascular education with support, reassurance and motivation. The participants' blood pressure, walking impairment, quality of life, anxiety and depression were monitored and reviewed. Results Overall, the participants' walking distance, intermittent claudication, quality of life and blood pressure had improved. The participants' overall satisfaction with the programme was excellent. The programme also demonstrated clinical and cost-effectiveness. Conclusions A structured, supervised exercise programme can have considerable benefits for people with peripheral arterial disease, improving their symptoms and quality of life. It may also help to reduce the morbidity and mortality risks associated with inactivity in this patient group.
