RESUMO
Objective To explore the relationship between those myocardial markers serum cardiac troponin T (cTNT),serum cardiac troponin I (cTNI),N-terminal pro-brain natriuretic peptide (NT-proBNP),echocardiography and myocardial injury in the oldest-old septic patients,as well as to evaluate prognosis in the oldest-old septic patients.Methods 140 oldest-old septic patients hospitalized in Beijing Friendship Hospital from January 1 st,2015 to Jun 31st,2017 were collected and analyzed retrospectively.They were divided into survival group (90 cases) death group (50 cases)according to their survival time.Serum cTNT,cTNI and NT-proBNP level at 1,3 and 7d post-diagnosis were collected and echocardiography left ventricular diastolic diameter (EDD),left ventricular systolic diameter (ESD),right ventricular diameter (RV),left ventricular ejection fraction (EF) was performed.Results 140 oldest-old septic patients were enrolled in the analysis.There were 90 cases in survival group and 50 cases in death group.Mean values of cTNT,cTNI,NT-proBNP,EDD,ESD in survival group were obviously higher than those in death group (P ＜ 0.05),left ventricular ejection fraction (LVEF) in survival group was lower than that in death group (P ＜ 0.01).But there were no difference in E/A and RV between survival group and death group (P ＞ 0.05).There were positive correlation between cTNT,cTNI,NT-proBNP and EDD,ESD (P ＜ 0.05),negative correlation between cTNT,cTNI,NT-proBNP and LVEF (P ＜ 0.05),and no correlation between cTNT,cTNI,NT-proBNP and E/A,RV (P ＞0.05).There were obviously correlation between cTNT,cTNI,NT-proBNP,EDD,ESD and mortality rate (OR ＞ 1,P ＜ 0.05).It was shown the prognosis value of cTNT,cTNI,NT-proBNP,EDD,ESD to mortality rate in oldest-old septic patient.The prognosis value was cTNT ＞ NT-proBNP ＞ cTNI ＞ EDD ＞ ESD.Conclusions There were obviously correlation between cT NT,cTNI,NT-proBNP,EDD,ESD and myocardium restrain,heart dysfunction as well as mortality rate.cTNT was the best prognosis indicator in sensitivity,and NT-proBNP was the best prognosis indicator in specificity.The combination of cTNT and NT-proBNP can better forecast the prognosis of the oldest-old septic patient.
RESUMO
Objective To observe the changes of red blood cell distribution width, mean platelet volume and cardiac troponin I in patients with Acute Coronary Syndromes, and to evaluate the value for early diagnosis by using ROC curve. Methods 191 patients with ACS and 206 patients with the chest pain syndromes non-ACS were selected in this study. Electrocardiogram,blood routine,creatinine, LDL-C and cardiac troponin I were determined within six hours after hospitalized,meanwhile the feature of ROC curves was observed. Results There was no significant difference between ACS group and non-ACS group about red blood cell, hemoglobin, platelet,creatinine and LDL-C［(3.82±0.57)×1012/L,(101.3±3.3)g/L,195（98.6-334.8）×109/L,69（45-120）μmol/L,(2.95±0.85)mg/dl vs (3.89±0.50）×1012/L,(103.5±3.7)g/L,201（135.2-346.9）×109/L,71（49-100）μmol/L,(2.82±0.75)mg/dL］ (P＞ 0. 05). Red blood cell distribution width, mean platelet volume and the cardiac troponin I in ACS group［13.70(12.00-15.20)%,9.4（7.42-12.31）fL,(5.63±1.39)μg/L］ were significantly higher than that of non-ACS group［12.60（11.20-13.83）%,8.2（6.24-10.97）fL,(0.04.±0.01)μg/L］ (P＜0.01) .The area under ROC curves of red blood cell distribution width,mean platelet volume and cardiac troponin I were 73.5%, 78.8%, 98.1% respectively, while the best cut-off value was 13.15%, 12.45 fL, 0.06 μg/L respectively. Conclusions The combination using of red blood cell distribution width andmean platelet volume and cardiac troponin I and other conventional cardiac markers might be served as early diagnosis marker for the ACS patients admitted to emergency departments.
RESUMO
Objective To discuss the clinical significance of the changes of endothelin-1 and troponin-1 levels in kawasaki disease after acute stage. Methods 60 patients of kawasaki disease in which 12 cases of patient were complicated with coronary artery disease and 48 cases of patient who were not complicated with coronary artery disease were enrolled this study. Blood plasma endothelin-1 and serum cardiac troponin I were determined in kawasaki disease acute phase and recovery phase and 30 healthy children. Results Acute phase ET-1 and cTnI [(90.19±3.43)ng/L, (1.35±0.14)μg/L] and recovery phase ET-1 and cTnI [(89.09±2.44)ng/L, (1.12±0.11)μg/L ] in coronary artery lesions of (CAL) group had no significant difference（P＞0.05）. The concentration values of ET-1, cTnI in no coronary artery lesions (NCAL) group of acute phase (64.49±4.78)ng/L,(0.62±0.02)μg/L were different with convalescent phase (50.47±4.49)ng/L,(0.07±0.05)μg/L. There were significant difference between the the two phases (P＜0.01). Plasma endothelin-1 and serum troponin I concentrations were positively correlated in acute phase of Kawasaki disease in children (r＝0.93,0.96,P＜0.01). Conclusions Plasma endothelin-1 and serum cardiac troponin I test for the diagnosis of Kawasaki disease with coronary artery disease may be early indicators of risk monitoring, they are valuable indexes in diagnosis and treatment of Kawasaki disease.
