Effect of chronic local cold exposure on finger temperature responses.
17(2): 3’7-322. I g62.-Caucasian subjects from a temperate climate immersed their right index fingers in a stirred icewater bath for 20 min four times daily for I month. During subsequent test immersion, fingers exposed in this way showed an earlier initiation and a more rapid rate of spontaneous rewarming and a higher and more labile final temperature level than did either the same finger befo...
متن کاملCold feet and prolonged sleep-onset latency in vasospastic syndrome.
People with vasospastic syndrome have cold hands and feet and abnormal vasoconstriction after local cold exposure. Normally there is a circadian rhythm of distal vasodilation, with onset in the early evening, which directly influences ability to fall asleep. We gave a sleep questionnaire to 32 patients with primary vasospastic syndrome and 31 healthy controls. People with vasospasticity had sig...
متن کاملPerfusion of the human finger during cold-induced vasodilatation.
We have investigated the effect of severe local cooling on the vasomotor activity of the arteriovenous anastomoses (AVAs) and other finger vessels. The right third finger was subjected to local cooling (3°C) for 30-45 min in 21 healthy, thermoneutral subjects. Blood velocity in the third finger arteries of both hands was simultaneously recorded using ultrasound Doppler, and skin temperature and...
متن کاملImportance of the Spasm Provocation Test in Diagnosing and Clarifying the Activity of Vasospastic Angina
Background: Some patients with Intractable Vasospastic Angina (i-VSA) have angina attacks, irrespective of vasodilator treatment. Despite the significance of the prediction of i-VSA in the clinical setting, the means to accomplish it remain unclear. Therefore, we investigated the relationship between i-VSA clinical parameters, including angiographic findings from the Spasm Provocation Test (SPT...
متن کاملHypohydration effect on finger skin temperature and blood flow during cold-water finger immersion.
This study was conducted to determine whether hypohydration (Hy) alters blood flow, skin temperature, or cold-induced vasodilation (CIVD) during peripheral cooling. Fourteen subjects sat in a thermoneutral environment (27 degrees C) during 15-min warm-water (42 degrees C) and 30-min cold-water (4 degrees C) finger immersion (FI) while euhydrated (Eu) and, again, during Hy. Hy (-4% body weight) ...
