Body-temperature circadian rhythm in 67 patients after heart valve replacement surgery secondary to valvular heart disease

摘要

PurposePatient body temperature was monitored after cardiac valve replacement, in order to explore the characteristics of body-temperature circadian rhythm and the factors influencing that rhythm.MethodsA cohort of 67 patients who received cardiac valve replacement in a Fuzhou, Fujian province, China, general hospital underwent temperature measurements and analysis (by cosine curve) of their body-temperature circadian rhythm. A biological rhythm model was established through principal component analysis and evaluation of biological rhythm features. Multiple circadian parameters were included through linear regression analysis.ResultsPatients' temperature after cardiac valve replacement exhibited circadian characteristics (p?
