Sex-Specific Differences in Upstream Cardiac Damage in Patients With Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement (TAVR)
Authors' conclusion
The pattern of cardiac damage secondary to AS differed by sex. In early stages of cardiac damage, women had a lower 5-year mortality than men, whereas in more advanced stages, mortality was comparable between sexes.
Study context

- Outcome
- Distribution of cardiac damage stages (0–4) by sex on pre-TAVR echocardiography, and all-cause mortality by stage
- Follow-up
- 5 years

| Outcome | Adjusted HR (95% CI) | |
|---|---|---|
| 5-year all-cause mortality per stage increase (linear trend) · 5 years — Women · for linear trend | 1.43 (1.28–1.60) | |
| 5-year all-cause mortality per stage increase (linear trend) · 5 years — Men · for linear trend | 1.26 (1.14–1.38) | |

5-year mortality, women vs men, by stage
- Female sex associated with lower 5-year mortality in early stages (0, 1 or 2) but not in advanced stages (3 or 4)
