Prompt value of MRI scanner-detected temporalis muscle thickness in patients with stroke / 中华老年医学杂志

ABSTRACT

Objective:To investigate the relationship of sarcopenia diagnosed by temporalis muscle thickness(TMT)with physical status and prognosis of stroke patients.Methods:Temporalis muscle thickness was detected by MRI scanner.The median value of TMT was used as the risk classification index of sarcopenia in 265 stroke patients.The relationships of TMT with several indicators of Essen Stroke Risk Score(ESRS), National Institutes of Health Stroke Scale(NIHSS), Barthel index, water swallow test, Venous thromboembolism(VTE)assessment of medical inpatients, as well as the modified Rankin Score(mRS)follow-up results at 3 and 6 months after discharge were retrospectively analyzed.Results:There were 166 men and 99 women in the study cohort, with an average age of(62±13.1)years.The TMT value of men was 0.58 mm, which was significantly higher than that of women( t=2.307, P<0.05).There were significant differences in age( χ2=33.443, P<0.001), albumin( t=-2.467, P<0.05), triglyceride( Z=-2.777, P<0.01)and hemoglobin( t=-3.264, P<0.001)between sarcopenia group and non-sarcopenia group.As compared with non-sarcopenia group, atherosclerosis( χ2=4.715, P<0.05), pulmonary infection( χ2=4.707, P<0.05)and hypertension( χ2=4.046, P<0.05)were easy to be accompanied in sarcopenia group.There was good agreement in TMT measurements among different investigators(ICC=0.980, P<0.001).After adjusting for confounding variables, Logistic regression analysis showed that sarcopenia was significantly correlated with ESRS( OR=1.92, P< 0.05)and Barthel index( OR=1.66, P< 0.05)at admission, and Barthel index after discharge( OR=1.84, P<0.05), mRS at 3 months after discharge( OR=3.09, P<0.001), mRS at 6 months after discharge( OR=3.36, P<0.001). Conclusions:TMT can be used as a comprehensive index to dynamically display the physical state and prognosis of stroke patients, but further research is needed to determine the causal relationship.
