Difference of Clinical Outcomes According to Left Ventricular Hypertrophy and Its Subtype in Korean Patients with Acute Myocardial Infarction / 대한내과학회지

Background/Aims@#Left ventricular hypertrophy (LVH) on clinical outcomes in patients with acute myocardial infarction (AMI) is not clear. This study was performed to investigate the effect of abnormal left ventricular geometry on clinical outcomes in Korean patients with AMI. @*Methods@#A total of 852 consecutive patients with AMI were divided into two groups: normal left ventricular geometry (n = 470; 389 males) and LVH (n = 382; 214 males) groups. Major adverse cardiac events (MACEs) were defined as cardiac death, recurrent myocardial infarction, and rehospitalization. @*Results@#During the clinical follow-up period of 21 ± 7.8 months, MACEs developed in 173 patients (20.0%), and the rate was higher in the LVH than normal left ventricular geometry groups (25.5% vs. 16.0%, respectively, p = 0.001). According to Kaplan-Meier survival curves, the MACE-free survival rate was significantly lower in the LVH group than in the left ventricular geometry group (p = 0.008). The rates of MACEs and all-cause mortality differed among the AMI with concentric remodeling, concentric hypertrophy, and eccentric hypertrophy subgroups (11.2% vs. 15.5% vs. 22.1%, respectively, p = 0.046). Eccentric hypertrophy was a predictive factor of MACE according to Cox proportional hazards analysis (hazard ratio 1.804, confidence interval 1.034-3.148, p = 0.038). @*Conclusions@#LVH is a predictor of poor outcomes in patients with AMI, and eccentric hypertrophy is associated with a worse prognosis compared with concentric remodeling and concentric hypertrophy. Therefore, Korean patients with AMI and LVH, especially eccentric hypertrophy, require more careful observation and intensive treatment.

Discriminative Effects of Social Skills Training on Facial Emotion Recognition among Children with Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder

OBJECTIVES: This study investigated the effect of social skills training (SST) on facial emotion recognition and discrimination in children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). METHODS: Twenty-three children aged 7 to 10 years participated in our SST. They included 15 children diagnosed with ADHD and 8 with ASD. The participants' parents completed the Korean version of the Child Behavior Checklist (K-CBCL), the ADHD Rating Scale, and Conner's Scale at baseline and post-treatment. The participants completed the Korean Wechsler Intelligence Scale for Children-IV (K-WISC-IV) and the Advanced Test of Attention at baseline and the Penn Emotion Recognition and Discrimination Task at baseline and post-treatment. RESULTS: No significant changes in facial emotion recognition and discrimination occurred in either group before and after SST. However, when controlling for the processing speed of K-WISC and the social subscale of K-CBCL, the ADHD group showed more improvement in total (p=0.049), female (p=0.039), sad (p=0.002), mild (p=0.015), female extreme (p=0.005), male mild (p=0.038), and Caucasian (p=0.004) facial expressions than did the ASD group. CONCLUSION: SST improved facial expression recognition for children with ADHD more effectively than it did for children with ASD, in whom additional training to help emotion recognition and discrimination is needed.

Difference of Facial Emotion Recognition and Discrimination between Children with Attention-Deficit Hyperactivity Disorder and Autism Spectrum Disorde

OBJECTIVES: This study aimed to investigate the differences in the facial emotion recognition and discrimination ability between children with attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). METHODS: Fifty-three children aged 7 to 11 years participated in this study. Among them, 43 were diagnosed with ADHD and 10 with ASD. The parents of the participants completed the Korean version of the Child Behavior Checklist, ADHD Rating Scale and Conner's scale. The participants completed the Korean Wechsler Intelligence Scale for Children-fourth edition and Advanced Test of Attention (ATA), Penn Emotion Recognition Task and Penn Emotion Discrimination Task. The group differences in the facial emotion recognition and discrimination ability were analyzed by using analysis of covariance for the purpose of controlling the visual omission error index of ATA. RESULTS: The children with ADHD showed better recognition of happy and sad faces and less false positive neutral responses than those with ASD. Also, the children with ADHD recognized emotions better than those with ASD on female faces and in extreme facial expressions, but not on male faces or in mild facial expressions. We found no differences in the facial emotion discrimination between the children with ADHD and ASD. CONCLUSION: Our results suggest that children with ADHD recognize facial emotions better than children with ASD, but they still have deficits. Interventions which consider their different emotion recognition and discrimination abilities are needed.
