Background Unlike tachyarrhythmias, which are common in pregnancy, there is a paucity of data regarding maternal bradycardias. Our objective was to describe the characteristics, associated conditions, and prognosis of women who develop bradycardia post-partum. Method We conducted a retrospective chart review of patients referred to the Obstetrical Medicine service at British Columbia Women's Hospital from January 2012 to May 2020 for post-partum maternal bradycardia. Results Twenty-four patients with post-partum bradycardia were included (age 34.2 ± 4.8 years; heart rate 40.4 ± 8.1 beats per minute; blood pressure 131/72 mm Hg). Sinus bradycardia (79.2%) was the most common rhythm. Dyspnea (29.4%) and chest pain (23.5%) were common symptoms. Mean time to resolution of bradycardia was 3.6 ± 3.8 days. Associated conditions potentially explaining the bradycardia were preeclampsia (54.1%), underlying (16.7%), medications (8.3%), and neuraxial anesthesia (8.3%). Conclusions Maternal bradycardia is an uncommon condition complicating the post-partum period, that is generally self-limiting, with the majority only require clinical observation.
Background Women with ST‐elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention historically experience worse in‐hospital outcomes compared to men. Hypothesis Implementation of a regional STEMI system will reduce care gaps in reperfusion times and in‐hospital outcomes between women and men. Methods 1928 patients (413 women, 21.4%) presented with an acute STEMI between June 2007 and March 2016. The population was divided into an early cohort (n = 728 patients, 2007‐May 2011), and a late cohort (n = 1200 patients, June 2011–2016). The primary endpoints evaluated were reperfusion times and in‐hospital outcomes. Results Compared to men, women experienced significant delays in first medical contact (FMC) to arrival at the emergency room (26.0 vs. 22.0 min, p < 0.001) and FMC‐to‐device (109 vs. 101 min p = 0.001). Women had higher incidences of post‐PCI heart failure and death compared to men (p < 0.05). Following multivariable adjustment, no mortality difference was observed for women versus men (adjusted OR; 0.82; 95% confidence interval [CI], 0.51–1.34; p = 0.433) or for early versus late cohorts (adjusted OR; 1.04; 95% CI, 0.68–1.60; p = 0.856). Conclusion Following STEMI regionalization, women continued to experience significantly longer reperfusion times, although there was no difference in adjusted mortality. These results highlight the ongoing disparity of STEMI care between women and men, and suggest that regionalization alone is insufficient to close sex‐based care gaps.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
