Objective:To identify the risk factors of anxiety disorders among patients undergoing coronary angiography (CAG) and to determine whether the decision of revascularization affect anxiety level following coronary angiography.
Methods:A total of 379 patients undergoing CAG in Fuwai Hospital from Dec. 2012 to Dec. 2013 were invited to participate this study. A data-collecting form, which included questions about demographic features, health history, Type A Behavior Questionnaire (TABQ) and Self Rating Anxiety Scale (SAS), was completed by the participants on the day before and the day after CAG.
Result:Among these patients, SAS score of both before and the day after CAG were higher than Chinese normative SAS score. Female patients had a higher SAS score level than male patients (40.57±9.53 vs 38.26±9.61, P<0.05) before CAG. Patients with these factors of female, over 50 years old, duration of coronary artery disease over 1 year, lower education level had a higher SAS score after CAG. SAS score declined signiifcantly after CAG except those scheduled to receive CABG. Multivariable linear analysis found the D-value between SAS scores before and after CAG was negative correlated with degree of education and positive correlated with the duration of coronary artery disease.
Conclusion:The anxiety level decreased after CAG, except those who need coronary revascularization surgery.

Objective:To investigate the correlation between specific expression of serum micro ribonucleic acid (miRNA) and dilated cardiomyopathy (DCM) in children.Methods:Sixteen children diagnosed with DCM in Pediatric Heart Center of Beijing Anzhen Hospital from November 2013 to March 2016 were enrolled in the DCM group.Meanwhile, 12 age- and gender-matched healthy children who underwent medical examinations at the same time in the same hospital were selected as the healthy control group.Their serum was collected and miRNA sequencing was performed.The sample size was expanded at the later stage (the DCM group included 30 cases, and the healthy control group included 16 cases). The real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) verification experiment was conducted on 11 miRNAs with statistically significant sequencing results.Results:Serum miRNA sequencing showed that 172 miRNAs were up-regulated but no miRNAs were down-regulated in the DCM group, compared with the healthy control group (fold change>2, P<0.001). Top 11 significantly up-regulated miRNAs were verified by qRT-PCR, and it was found that 8 of the 11 miRNAs (let-7f, let-7g, miR142-5p, miR143-3p, miR26a, miR27a-3p, miR27b-3p, and miR126-3p) in the DCM group were significantly up-regulated (all P<0.05). In the receiver operating characteristic (ROC) curves of DCM patients, the area under the curves of serum miR142-5p, miR143-3p, miR27b-3p, and miR126-3p were 0.983, 0.992, 0.915 and 0.950, respectively, which were statistically significantly different from those of the healthy control group (all P<0.05). Conclusions:Four serum miRNAs (miR-142-5p, miR-126-3p, miR-143-3p and miR-27b-3p) can distinguish children with DCM from healthy children.Circulating miRNAs are effective in screening DCM children.

Interarterial subtype of coronary artery with anomalous aortic origin is a rare and congenital cardiovascular malformation,manifested by chest pain and syncope after exertion or activity,which can lead to decreased cardiac contractility,myocardial infarction,and even sudden death.Here we report a case of an adolescent patient,who presented with chest pain during activity accompanied by syncope and lost consciousness.Initially diagnosed with acute myocardial infarction,the patient was subsequently diagnosed as interarterial subtype of a coronary artery originating from anomalous aorta after echocardiography,coronary angiography,coronary CT angiography examinations.After anomalous coronary artery correction and coronary angioplasty,the paitent recovered well.
