Summary
Women with ST-segment elevation myocardial infarction (STEMI) experience worse outcomes and are less likely to go home after treatment. These sex-based disparities persist even within a structured regional STEMI care system.
Area of Science:
- Cardiology
- Health Services Research
Background:
- Women with ST-segment elevation myocardial infarction (STEMI) have higher mortality rates than men.
- Biologic differences and care disparities are implicated, but their persistence in regional STEMI systems is unclear.
Purpose of the Study:
- To explore sex-related effects on outcomes within a large, regionalized STEMI system of care.
- Investigate if established sex-based disparities in STEMI care persist.
Main Methods:
- Analysis of data from the National Cardiovascular Data Registry (2010-2015) for 33 hospitals in the Dallas County, Texas region.
- Exploration of adjusted differences between women and men for discharge disposition, door-to-balloon time (D2B), total ischemic time (TIS), length of stay, and in-hospital mortality.
Main Results:
- Women experienced significantly longer door-to-balloon (58 vs. 54 min) and total ischemic times (206 vs. 178 min).
- Women had a longer median length of stay (0.45 days) and lower survival rates (OR: 0.63; 95% CI: 0.52-0.76).
- Women were less likely to be discharged home (88% vs. 92%).
Conclusions:
- Sex-based disparities in cardiovascular outcomes and discharge disposition persist in women with STEMI.
- These disparities are evident even within a modern, regionalized system of care with defined protocols.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

01:27RC Circuits: Discharging A Capacitor
4.5K
One of the applications of an RC circuit is the relaxation oscillator. The relaxation oscillator comprises a voltage source, a capacitor, a resistor, and a neon lamp. The lamp acts like an open circuit (infinite resistance) until the potential difference across the neon lamp reaches a specific voltage. At that voltage, the lamp acts like a short circuit (zero resistance), and the capacitor discharges through the neon lamp and produces light. Once the capacitor is fully discharged through the...

11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...
