Sociodemographic Factors And The Risk Of Paediatric Out-Of-Hospital Cardiac Arrest, Samina Idrees
Electronic Thesis and Dissertation Repository
Paediatric out-of-hospital cardiac arrest (POHCA) is associated with poor survival and severe neurological sequelae. This thesis aims to explore the relationship between sociodemographic factors and POHCA. The findings from our systematic review indicate that there are racial disparities in POHCA risk and in the provision of bystander cardiopulmonary resuscitation. There was little evidence of sociodemographic disparities in bystander defibrillation, survival and neurological outcome, particularly across adjusted analyses. The findings from our case-control study in Ontario, Canada, indicate that children living in marginalized areas have an elevated risk of experiencing POHCA. We also found that children living in northern urban or …
Physical Exertion As A Risk Factor For Ventricular Arrhythmia: A Prospective Cohort Study, Harpreet S. Chahal
Physical Exertion As A Risk Factor For Ventricular Arrhythmia: A Prospective Cohort Study, Harpreet S. Chahal
Electronic Thesis and Dissertation Repository
Episodes of physical exertion are associated with an immediately higher risk of cardiovascular events while physical activity over the long-term is cardioprotective. To assess the transient and long-term risk of ventricular arrhythmia (VA), we conducted a nested case-crossover study within a prospective cohort of 97 patients with implantable cardioverter-defibrillators (ICD). Within an hour of episodes of exertion, the risk of VA was 5.3 (95% CI 2.7 – 10.6) times greater compared to periods of rest. The association was higher among patients with aerobic fitness below the median (RR[relative risk]=17.5, 95% 5.2 – 58.5) than for patients with aerobic fitness above …
