High School Cardiac Emergency Response Plans and Sudden Cardiac Death in the Young.

Introduction Sudden cardiac death (SCD) is responsible for 5%-10% of all deaths among children 5-19 years-of-age. The incidence of SCD in youth in Michigan (USA) and nationwide is higher in racial/ethnic minorities and in certain geographic areas. School cardiac emergency response plans (CERPs) increase survival after cardiac arrest. However, school cardiac emergency preparedness remains variable. Studying population-level factors associated with school cardiac emergency preparedness and incidence of SCD in the young may improve understanding of disparities in the incidence of SCD. Hypothesis/Problem The objective of this pilot study was to determine the association of elements of high school cardiac emergency preparedness, including Automated External Defibrillator (AED) distribution and the presence of CERPs with county sociodemographic characteristics and county incidence of SCD in the young. METHODS: Surveys were sent to representatives from all public high schools in 30 randomly selected Michigan counties. Counties with greater than 50% response rate were included (n=19). Association of county-level sociodemographic characteristics with incidence of SCD in the young and existence of CERPs were evaluated using Spearman correlation coefficient. RESULTS: Factors related to the presence of AEDs were similar across counties. Schools in counties of lower socioeconomic status (SES; lower-median income, lower per capita income, and higher population below poverty level) were less likely to have a CERP than those with higher SES (all P<.01). Lack of a CERP was associated with a higher incidence of SCD in youth (r=-0.71; P=.001). Overall incidence of SCD in youth was higher in lower SES counties (r=-0.62 in median income and r=0.51 in population below poverty level; both P<.05). CONCLUSION: County SES is associated with the presence of CERPs in schools, suggesting a link between school cardiac emergency preparedness and county financial resources. Additionally, counties of lower SES demonstrated higher incidence of SCD in the young. Statewide and national studies are required to further explore the factors relating to geographic and socioeconomic differences in cardiac emergency preparedness and the incidence of SCD in the young.

Availability of Automated External Defibrillators in Public High Schools.

OBJECTIVES: To assess automated external defibrillator (AED) distribution and cardiac emergency preparedness in Michigan secondary schools and investigate for association with school sociodemographic characteristics. STUDY DESIGN: Surveys were sent via electronic mail to representatives from all public high schools in 30 randomly selected Michigan counties, stratified by population. Association of AED-related factors with school sociodemographic characteristics were evaluated using Wilcoxon rank sum test and χ(2) test, as appropriate. RESULTS: Of 188 schools, 133 (71%) responded to the survey and all had AEDs. Larger student population was associated with fewer AEDs per 100 students (P < .0001) and fewer staff with AED training per AED (P = .02), compared with smaller schools. Schools with >20% students from racial minority groups had significantly fewer AEDs available per 100 students than schools with less racial diversity (P = .03). Schools with more students eligible for free and reduced lunch were less likely to have a cardiac emergency response plan (P = .02) and demonstrated less frequent AED maintenance (P = .03). CONCLUSIONS: Although AEDs are available at public high schools across Michigan, the number of AEDs per student varies inversely with minority student population and school size. Unequal distribution of AEDs and lack of cardiac emergency preparedness may contribute to outcomes of sudden cardiac arrest among youth.

Successful staged neonatal repair of tetralogy of Fallot with long-segment hypoplasia of the aorta.

We describe an extremely rare combination of tetralogy of Fallot (TOF), right-sided cervical aortic arch with long-segment hypoplasia, and other vascular anomalies. A two-stage surgical approach included aortic arch reconstruction followed by right ventricular muscle bundle division and ventricular septal defect closure a few weeks later. The initial clinical presentation, perioperative course, and imaging studies are presented along with a review of the relevant literature. This is the first report of successful neonatal repair of TOF with long-segment hypoplasia of the aorta.

Hostility and anomie: links to preterm delivery subtypes and ambulatory blood pressure at mid-pregnancy.

Underlying maternal vascular disease has been implicated as one of several pathways contributing to preterm delivery (PTD) and psychosocial factors such as hostility, anomie, effortful coping, and mastery may be associated with PTD by affecting maternal vascular health. Using data from the Pregnancy Outcomes and Community Health (POUCH) study, we included 2018 non-Hispanic White and 743 African American women from 52 clinics in five Michigan, USA communities. Women were interviewed at 15-27 weeks' gestation and followed to delivery. We found that relations between psychosocial factors and PTD subtypes (i.e. medically indicated, premature rupture of membranes, spontaneous labor) varied by race/ethnicity and socio-economic position (Medicaid insurance status). Among African American women not insured by Medicaid, anomie levels in mid-pregnancy were positively associated with medically indicated PTD after adjusting for maternal age and education. Among all women not insured by Medicaid, hostility levels were positively associated with spontaneous PTD after adjusting for maternal race/ethnicity, age, and education. Failure to detect links between psychosocial factors and PTD risk in poorer women may be due to their excess risk in multiple PTD pathways and/or a more complex web of contributing risk factors. In a subset of 395 women monitored for blood pressure, anomie scores were positively associated with systolic blood pressure and heart rate and hostility scores were positively associated with systolic and diastolic blood pressure, heart rate and mean arterial pressure in models that included time, awake/asleep, race/ethnicity, and age as covariates. Further adjustment for body mass index and smoking attenuated the anomie-vascular relations but had little effect on the hostility-vascular relations. Overall this study of pregnant women provides some physiologic evidence to support findings linking levels of anomie and hostility with risk of PTD.
