Disparities in 5-year outcomes and imaging surveillance following elective endovascular repair of abdominal aortic aneurysm by sex, race, and ethnicity.
The purpose of this study was to identify variations in 5-year outcomes and imaging surveillance after elective endovascular aortic aneurysm repair (EVAR) by sex, race, and ethnicity and to examine possible mechanisms contributing to these variations. The primary outcome was 5-year aneurysm rupture. Secondary outcomes were 5-year reintervention and mortality, and having no aortic imaging follow-up from 6 to 24 months after EVAR. The study found that among 16,040 patients, 73% were White males, 18% were White females, 2.6% were Black males, 1.1% were Black females, 0.9% were Asian males, 0.2% were Asian females, 1.7% were Hispanic males, and 0.4% were Hispanic females. At 5 years, Black females had the highest rupture rates at 6.4% and white males had the lowest at 2.3%. Compared with White males, rupture rates were higher in White females, Black females, and Asian females. Among other groups, Black males had higher reintervention and both Black and Hispanic males had higher rates of no imaging follow-up. In adjusted analyses, White, Black, and Asian females remained at significantly higher risk for 5-year rupture. The researchers concluded that Black females had higher 5-year aneurysm rupture, reintervention, and mortality rates after elective EVAR as compared with White male patients, whereas White females had higher rupture, mortality and loss-to-imaging-follow-up compared to White male patients. Black males had higher reintervention and no imaging follow-up, and Asian females had higher rupture rates.

Disparities in reporting and representation by sex, race, and ethnicity in endovascular aortic device trials.
The purpose of this study was to examine the demographics of patients enrolled in critical U.S. endovascular aortic device trials to explore the representation of vulnerable populations, including women and racial and ethnic minorities. The primary outcomes included the percentage of trials reporting participant sex, race, and ethnicity and the percentage of participants across sex, racial, and ethnic groups. The study found that the Food and Drug Administration (FDA) provided 29 approvals from 29 trials of 24 devices with a total of 4046 patients: 52% (15) were EVAR devices, 41% (12) were TEVAR devices, and 3.4% (1) was a FEVAR device, with 1 dissection stent (3.4%). Fifty-two percent of the trials reported the three most common racial groups (White, Black, Asian), and 48% reported Hispanic ethnicity. The TEVAR trials were the most likely to report all three racial groups and Hispanic ethnicity (92% and 75%, respectively), while the EVAR trials had the lowest reporting rates (13% and 20%, respectively). The median female enrollment was 21%, with the EVAR trials having the lowest female enrollment compared with 41% in the TEVAR trials, 21% in the FEVAR trial, and 34% in the dissection stent trial. The study concluded that in critical aortic device trials that led to FDA approval, female patients were underrepresented, especially for EVAR, and racial and ethnic minority groups were under-represented and underreported.

Sex differences in timeliness of reperfusion in young patients with ST-segment-elevation myocardial infarction by initial electrocardiographic characteristics.
Investigators aimed to determine the electrocardiographic correlates of delay in reperfusion in young patients with ST-segment-elevation myocardial infarction. They found that sex disparities in timeliness to reperfusion in young patients with ST-segment-elevation myocardial infarction persisted, despite adjusting for initial electrocardiographic characteristics. They concluded that left ventricular hypertrophy by voltage criteria and absence of prehospital ECG are strongly positively correlated and ST elevation in lateral leads is negatively correlated with reperfusion delay.

Race- and sex-related differences in care for patients newly diagnosed with atrial fibrillation.
The researchers sought to determine whether significant race and sex differences exist in the treatment of newly diagnosed AF in Medicare beneficiaries. They found that there were statistically significant differences in the use of AF-related services by both race and sex, with white patients and male patients receiving the most care.

Sex differences in reperfusion in young patients with ST-segment-elevation myocardial infarction: results from the VIRGO study.
Sex disparities in reperfusion therapy for patients with acute ST-segment-elevation myocardial infarction have been documented. The authors tested these patterns in the comparison of young women with men.They found that young women with ST-segment-elevation myocardial infarction are less likely to receive reperfusion therapy and more likely to have reperfusion delays than similarly aged men.
