Risk factors of death in 30 days after syncope / 中华急诊医学杂志

Objective To investigate the risk factors of death in patients with syncope. Methods Clinical data of 516 patients experienced syncope admitted from June 2010 to June 2016 were analyzed retrospectively. Factors including gender, age, history of hypertension, diabetes mellitus, hyperlipidemia, smoking history, drinking history, and etiology of syncope (cardiogenic syncope, neuroreflex syncope, orthostatic hypotension, orthostatic syncope, unexplained syncope, and syncope caused by other special diseases) were analyzed as likely risk factors of death within 30 days after syncope happened. After adding the derived variables (over 22 new factors), analyses were done to investigate independent risk factors of death for patients with syncope. Results This study included 321 male (62.2％) and 195 females (37.8％), with mean age of (62.23±19.69) years. Logistic regression analyses showed that age (OR=1.033, 95％ confidence interval (95％CI):1.008-1.058, P =0.008 8),cardiac syncope (OR=19.704,95％CI:5.894-5.875,P＜0.01) were independent risk factors of death within 30 days after syncope occurred. Multiple-variate analysis with derived variables showed that cardiac syncope (OR=11.487, 95％CI:4.938-26.721,P＜0.01),age and age derived variables (OR=1.000, 95％CI:1.000-1.000,P=0.000 8),age and cardiogenic syncope derivative variables (OR=1.033, 95％CI:1.022-1.044, P＜0.01) were independent risk factors for death within 30 days after syncope. Conclusion Age and cardiogenic syncope were independent risk factors for death within 30 days after syncope occurred. And a derivative factor of age, and interactivity between age and cardiac syncope were independent risk factors of death in patients with syncope.

Syncope: Evaluation and Management.

Syncope is a common symptom in clinical practice. Causes can be relatively benign or potentially lethal. Knowledge of what actually occurs during a spontaneous syncopal episode is ideally the gold standard to determine etiology.

Common cause of cardiogenic syncope and emergency treatment / 中国小儿急救医学

Cardiogenic syncope is the relatively common type of syncope in children. The state of illness is more serious at the onset,the prognosis of partial patients is very dangerous,even it can cause cardiac sudden death, so clinical doctors pay close attention to cardiogenic syncope. The common pathogeny of cardiogenic syncope in children includes serious arrhythmia, obstruction of the outflow tract of heart, restricted diastole of heart or weak systole of heart. Before the particular cause of disease is determined,some examinations and laboratory tests should be made. In this article, the writer introduces detailed methods of the emergent treatment.

Prognosis and Etiological Treatment of Cardiogenic Syncope in Children / 实用儿科临床杂志

Objective To explore the prognosis and etiological treatment of cardiogenic syncope in children.Methods The cause,clinical manifestation,treatment and prognosis of 45 children with syncope were made in affiliated hospital of Qingdao medical university were su mmarized and analyzed.They were divided into arhythmia group and other groups,the former included myocarditis,dilated cardiomyopathy,and post-operation of congenital heart disease and the latter included tetralogy of fallot,pulmonary stenosis,hypertrophic cardiomyopathy,pericarclial effusion,and right atrial myxoma.Results There were 29 cases(64.44%) with arrhythmia in this group,of which there were 18 cases with complete atrioventricular block(CAVB),2 cases with second degree type Ⅱ atrioventricular block,3 cases with ventricular tachycardia,2 cases with bradycardia,2 cases with atrial flutter,1 case with supraventricular tachycardia,and 1 case with nonconducting atrial premature.There were 16 cases(35.56%) with other etiologies,of which there 8 cases with tetralogy of Fallot,2 cases with pulmonary stenosis,hypertrop-hic cardiomyopathy,pericardial effusion,and right atrial myxoma,respectively.Children with CAVB,bradycardia,or ventricular tachycardia resulted from viral myocarditis were given anti-virus medicine,protecting myocardium,neoepinephrine,and intravenous vitamin C 100-200 mg/(kg?d).Dexamethasone 1-2 mg/(kg?d) was given in earlier period for short course,and some children were given human ?-globulin.Eight cases were placed temporary pacemaker because of unsatisfactory therapeutic efficacy,and 1 case was placed permanent pacemaker.In all,38 cases(84.44%)were cured,1 case(2.22%)was improved,and 4 cases(8.88%) died.Conclusions Cardiogenic syncope is pediatric emergency and shall be treated immediately.Temporary pacemaker shall be placed at the right moment.
