Cohort study
Impact of Age and Sex on Left Ventricular Remodeling in Patients With Aortic Regurgitation
- Retrospective cohort study
- consecutive patients
- serial echocardiography
Authors' conclusion
On serial evaluation, older patients and women with chronic AR maintained smaller LV volumes than younger patients and men, respectively, and develop AE at lower LV volumes.
Study context
- Population
- Adults with severe aortic regurgitation (AR) serially monitored by echocardiogram, 2010–201626% women
- Participants
- 525 adults
- Exposure
- Left ventricular (LV) remodeling and adverse events (AE) by age and sex
- Outcome
- 1) LVESVi and LV end-diastolic volume indexed to BSA; 2) AE
Main finding
As reported in the abstract
