Preliminary study on predictors of early death risk in patients with exertional heat stroke
Objective:To explore indicators for rapid identification of short-term prognosis of patients with ex-ertive heat stroke by conducting statistical analysis on the 24-hour examination results of patients with occupation-al heat stroke upon admission.Methods:A total of 81 patients with heat stroke who admitted to our hospital from January 1,2016 to December 31,2022 were divided into survival group(58 cases)and death group(23 cases)ac-cording to 28-day prognosis.The basic data,test results and derived ratio were compared between the two groups.Multivariate Cox regression analysis,Kaplan-Meier survival curve and receiver operating characteristic curve analysis were used to find out the related indicators to predict the short-term prognosis.Results:The com-parison of various indicators between the two groups showed that there was a statistically significant difference in 29 indicators(P<0.05).Multivariate Cox regression analysis showed that the ratio of aspartate aminotransferase to alanine aminotransferase(P=0.02)and platelet distribution width(P=0.04)were independent risk factors af-fecting the prognosis of patients with heat stroke.Kaplan-Meier survival curve showed that the ratio of aspartate aminotransferase to alanine aminotransferase was correlated with the survival condition of patients(P<0.001),while the platelet distribution width was not correlated with the survival condition of patients(P>0.05).The re-ceiver operating characteristic curve analysis showed that the area under the curve of the ratio of aspartate amin-otransferase to alanine aminotransferase for predicting the prognosis of patients with exertional heat stroke was 0.738.Conclusion:The ratio of aspartate aminotransferase to alanine aminotransferase can be used as an index to predict the risk of early death in exertional heat stroke,which can be used to guide emergency physicians to strati-fied treatment.
