Hypertension was associated with a marked reduction in the PCI gender gap over time (from 9.4% to 1.0%), whereas no significant reduction was observed in patients without hypertension.

Are there gender disparities in the use of PCI for STEMI, and how do they change over time and with the presence of hypertension?
Gender disparities in PCI use for STEMI have significantly narrowed in Switzerland over the past 17 years, particularly among patients with hypertension.
Objective: The term Yentl Syndrome, coined by Bernadine Healy in 1991, refers to the disparities in the diagnosis and management of acute coronary syndromes between men and women. Using data from the Swiss nationwide AMIS Plus registry, we analyzed temporal trends of this gender gap in Switzerland with special emphasis on the presence of hypertension. Design and method: The AMIS Plus registry includes patients with acute myocardial infarction (MI) admitted to 62 Swiss hospitals, ranging from community to tertiary care centers. We analyzed gender differences in the use of percutaneous coronary intervention (PCI) across three consecutive 6-year periods (2007–2012, 2013–2018, 2019–2024) for ST-elevation MI (STEMI). Results: Between January 2007 and December 2024, 27,838 STEMI patients were enrolled. Of these, 21,021were men (75.5%) and 6,817 women (24.5%). Among 26,264 STEMI patients with available data 15,415 (55.4%) had hypertension. On average, hypertensive patients were eight years older (68.1 years, SD 12.4) than non-hypertensive patients (60.4 years, SD 12.6). (p1: 25% vs. 9%), and arrived at the hospital 39 minutes later than non-hypertensive patients. A significantly higher proportion of men than women underwent PCI in both hypertensive (91.5% versus 86.7%, p < 0.001) and non-hypertensive (95.1% versus 90.9%, p<0.001) patients. However, the gender gap in PCI use narrowed significantly over time. Among all STEMI patients, the gap decreased from 8.8% in 2007–2012, to 3.2% in 2013–2018, and 2.7% in 2019–2024. In STEMI patients with hypertension, gender gap declined across the three periods from 9.4% (p<0.001) to 2.4% (p=0.007) to 1.0% (p=0.323). In contrast, among STEMI patients without hypertension, no meaningful gender gap reduction in use of PCI was observed (4.4% to 3.6% to 4.6%) over the same periods. Conclusions: In this nationwide prospective registry, we observed a marked reduction in gender-related disparities in PCI use among STEMI patients in Switzerland between 2007 to 2024. This reduction was even more pronounced in hypertensive patients whereas in those without hypertension no significant reduction in the gender gap was observed.
Schoenenberger-Berzins et al. (Fri,) conducted a observational in ST-elevation myocardial infarction (STEMI) (n=27,838). Hypertension vs. No hypertension was evaluated on Gender gap in use of percutaneous coronary intervention (PCI). Hypertension was associated with a marked reduction in the PCI gender gap over time (from 9.4% to 1.0%), whereas no significant reduction was observed in patients without hypertension.
