ABSTRACT
Traumatic myocardial injury is a rare complication after blunt chest injury.The most common symptom is nonspecific chest pain, followed by ventricular premature beat and bundle branch block, with slight elevation of myocardial necrosis markers, which should be differentiated from acute myocardial infarction.One case of traumatic myocardial injury misdiagnosed as acute myocardial infarction was received in our hospital, except for acute myocardial infarction after corresponding examination.This kind of patients should be concerned by professional doctors, especially the elderly patients, who are more complicated with basic cardiovascular diseases, should be paid more attention in clinical work.
ABSTRACT
Objective: To study the effects of percutaneous coronary intervention (PCI) on blood levels of vascular endothelial growth factor (VEGF), high sensitivity C-reaction protein (hs-CRP) and fibrinogen (Fg) in patients with acute myocardial infarction (AMI). Methods: Our research included 2 groups: AMI group,n=110 patients with PCI and Control group,n=53 healthy subjects from physical examination. Blood levels of VEGF, hs-CRP and Fg were compared between pre-operation and 30 min, 24 h, 72 h post-operation; the peak values of VEGF, hs-CRP and Fg were compared between the patients with post-operative MACE occurrence at 24 h and the patients without MACE occurrence. Results:①Compared with Control group, blood levels of VEGF, hs-CRP and Fg in AMI group were increased at pre-operation and 30 min, 24 h, 72 h post-operation, for VEGF (pg/ml) as (84.7±21.4) vs (130.5±40.2) and (143.2±49.7), (107.1±31.8), (97.3±24.4); for hs-CRP (mg/L) as (1.03±0.34) vs (3.11±0.56) and (4.67±0.62), (6.42±0.72), (2.83±0.56); for Fg (mg/L) as (3.86±0.32) vs (4.79±0.52) and (5.02±0.54), (5.54±0.67), (4.11±0.44) respectively, allP Conclusion: Post-operative monitoring of blood levels of VEGF, hs-CRP and Fg had the important clinical value in AMI patients after PCI.
ABSTRACT
Objective To explore the correlation between serum growth differentiation factor‐15(GDF‐15) level and acute myocardial infarction(AMI) to provide a basis for the prognostic evaluation of AMI .Methods Totally 192 Han patients with AMI (AMI group) and non‐coronary heart disease (NCHD ,NCHD group) diagnosed in Chengde Municipal Central Hospital from Sep‐tember 2013 to January 2015 ,were selected and their clinical data were collected .The biochemical markers and serum GDF‐15 level were detected .Results Comparing the AMI group with the NCHD group ,differences in the patients′age ,smoking ,blood glucose (Glu) ,TC ,TG ,LDL‐C levels had statistical significance (P<0 .05);the serum GDF‐15 level in the AMI group was significantly higher than that in the NCHD ;serum GDF‐15 level was positively correlated with TC ,LDL‐C ,hs‐CRP and Glu in the AMI group . Conclusion The increase of serum GDF‐15 level is obviously correlated AMI ,therefore GDF‐15 can serve as an indicator for moni‐toring myocardial infarction .
ABSTRACT
Objective To approach the characteristics of low-field MRI in early stage of cerebral hemorrhage.Methods 38 cases with early stage of cerebral hemorrhage (superacute stage in 26 and acute stage in 12) underwent low-field MRI examination.Results The hematomas located in the basal ganglia regions in 23,thalamus in 9 and other intracerebral regions in 6.The hematomas appeared as reniform,suborbicular or irregular shape with different size.The hematomas exhibited homogeneously iso-intensity on T_1WI and iso-,slightly high or high signal intensity on T_2WI and FLAIR,in which 5 hematomas exhibited iso- or slightly high signal intensity on T_2WI,and 4 hematomas exhibited homogeneously or inhomogeneously high signal intensity on DWI.There was brain edema around the hematomas.25 hematomas had occupied effect,and 4 hemotomas broke into ventriculus and 2 hemotomas caused by hemorrhage of broken arteriovenous malformation.Conclusion Low-field MRI is of high sensitivity and specificity in diagnosis of early stage of cerebral hemorrhage.
ABSTRACT
Objective To explore the applied value of MRI in diagnosing pyogenic of infection of gluteus muscles.Methods MRI data in 9 cases with pyogenic infection of gluteus muscles proved by operation or biopsy were retrospectively analysed by comparison with the pathological diagnosis.Results The pyogenic infections localized at unilateral gluteus muscles involving single,two or three gluteus muscles in all cases.On MRI,the infective gluteus muscles were swelling diffusely and the infections developed along the long axis of the muscles and most or all gluteus muscles were involved.4 cases appeared as suppurative myositis and 5 cases developed typical abscess.4 cases were accompanied with subcutaneous edema and the abscess broken into skin in one case.Conclusion The pathological characteristics of the stage and extent of the pyogenic infection in gluteus muscles can be displayed by MR imaging.
