The clinical importance of vascular reactivity as an early marker of atherosclerosis has been well established, and a number of established and emerging techniques have been employed to provide measurements of peripheral vascular reactivity. However, relations between these methodologies are unclear as each technique evaluates different physiological(More)
Monitoring alterations in fingertip temperature during ischaemia and the subsequent hyperaemia provides a novel way of studying microvascular reactivity. The relations between parameters characterizing blood perfusion and the thermal response of fingertips were studied using experimental and theoretical approaches. During the experimental protocol, two(More)
This work is based on the premise that fingertip temperature variation during arterial occlusion and subsequent reperfusion can be used as an indirect measurement of vascular reactivity, commonly assessed by directly measuring flow and its temporal alterations in response to arterial occlusion. Temperature of the fingers depends on blood perfusion and(More)
BACKGROUND This paper presents calculations of the temperature distribution in an atherosclerotic plaque experiencing an inflammatory process; it analyzes the presence of hot spots in the plaque region and their relationship to blood flow, arterial geometry, and inflammatory cell distribution. Determination of the plaque temperature has become an important(More)
