Journal ArticleDOI

Cardiovascular health after maternal placental syndromes (CHAMPS): population-based retrospective cohort study.

TL;DR: The risk of premature cardiovascular disease is higher after a maternal placental syndrome, especially in the presence of fetal compromise, and a healthy lifestyle should be emphasised.
Journal ArticleDOI

Analysis of observational studies in the presence of treatment selection bias: effects of invasive cardiac management on AMI survival using propensity score and instrumental variable methods.

TL;DR: Estimates of the observational association of cardiac catheterization with long-term AMI mortality are highly sensitive to analytic method, and compared with standard modeling, instrumental variable analysis may produce less biased estimates of treatment effects, but is more suited to answering policy questions than specific clinical questions.
Journal ArticleDOI

Association between waiting times and short term mortality and hospital admission after departure from emergency department: population based cohort study from Ontario, Canada

TL;DR: Presenting to an emergency department during shifts with longer waiting times, reflected in longer mean length of stay, is associated with a greater risk in the short term of death and admission to hospital in patients who are well enough to leave the department.
Journal ArticleDOI

Association Between MRI Exposure During Pregnancy and Fetal and Childhood Outcomes.

TL;DR: Exposure to MRI during the first trimester of pregnancy compared with nonexposure was not associated with increased risk of harm to the fetus or in early childhood, and gadolinium MRI at any time during pregnancy was associated with an increasedrisk of a broad set of rheumatological, inflammatory, or infiltrative skin conditions and for stillbirth or neonatal death.
Journal ArticleDOI

Emergency department crowding and thrombolysis delays in acute myocardial infarction

TL;DR: ED crowding is associated with increased door-to-needle times for patients with suspected acute myocardial infarction and may represent a barrier to improving cardiac care in EDs.
