Low to Normal Plasma Levels of Marinobufagenin 24 Hours or More after an Ischemic Stroke: A Pilot Study.

Background: Numerous studies have demonstrated a strong relationship between circulating levels of marinobufagenin (MBG) and salt-sensitivity. Since salt-sensitive hypertensives have increased plasma levels of MBG and are known to be at a higher risk of having cardiovascular events, stroke and increased mortality, we evaluated the possibility of an association between MBG and ischemic stroke. In this pilot study, we determined plasma MBG levels in patients after surviving an ischemic stroke compared to similar age and gender groups of treated hypertensives and normotensive controls.

Impact of Day of the Week and Time of Arrival on Ischemic Stroke Management.

Objective: The purpose of this study was to evaluate the association between measures of patient arrival day (weekday or weekend day), day part (nighttime vs. daytime) and hour (regular hours vs. off hours) at the stroke unit of the Emergency Department of the Puerto Rico Medical Center and the following time-to-treatment measures: door-to-CT-scan, door-to-needle, and stroke-onset-to-treatment.
