Abstract:
Objective:To explore the predictive value of myocardial work echocardiography on short-term mortality of patients with sepsis and septic shock(SSS).Methods:Patients who hospitalized in the ICU department of the Affiliated Lianyungang Hospital of Xuzhou Medical University from September 2022 to December 2023 were selected through prospective research.These patients,who need use vasopressor drugs,appeared clinical symptoms of sepsis and occurred septic shock.A total of 33 adult patients were continuously enrolled.According to whether patients with SSS died or survived within 28 days,they were divided into a survival group(23 cases)and a non-survival group(10 cases).The changes of myocardial function,serum lactic acid level,white blood cell(WBC)count,c-reactive protein(CRP)and other indexes were compared and assessed between the two groups after admission,and the predictive value of these parameters on short-term mortality in patients with sepsis and septic shock was investigated.Results:On the 3rd day after admission of patients with sepsis and septic shock,the heart rate,serum lactic acid level,white blood cell(WBC)count,global wasted work(GWW),and high-sensitivity cardiac troponin Ⅰ(hs-cTnⅠ)of non-survival group significantly higher than those of survival group(Z=-2.668,-2.550,-2.338,-2.175,-2.998,P＜0.05),and the global work efficiency(GWE)of non-survival group significantly decreased(Z=-2.311,P＜0.05).On the 5th day after admission,the heart rate,serum lactic acid level,WBC count,c-reactive protein(CRP)level of non-survival group significantly increased(Z=-3.073,-2.494,-3.408,-2.999,P＜0.05),and the pH value and global work index(GWI)of that significantly decreased(Z=-1.997,-2.546,P＜0.05).Serum lactic acid on the 3rd day and global work index on the 5th day were respectively independent risk factors for 28-day mortality in SSS patients after admission(OR=5.120,0.997,P＜0.05).On the 5rd GwI and serum lactic acid on the 3rd have similar values in predicting 28-day mortality in SSS patients[area under curve(AUC)value of receiver operating characteristics(ROC)curve of them were respectively 0.784 and 0.801,P＞0.05].Conclusion:Myocardial work echocardiography is helpful to identify the high risk of short-term death of SSS patients.Serum lactic acid of the 3rd day and global work index of the 5th day after admission are respectively independent risk factors for 28-day death in SSS patients.
