Key result
Older age linked to ~37% higher risk of mortality and HF hospitalizations per decade in SAS.
Why the study?
There is a paucity of studies evaluating contemporary characteristics and outcomes of subaortic stenosis in adult patients.
Cohort (n=484)
No
Hazard Ratio: 1.37 (95% CI 1.12–1.68)
Adult patients with subaortic stenosis experience significant long-term mortality and morbidity, with older age and higher NYHA class serving as key prognosticators.

Adult subaortic stenosis portends high mortality and morbidity; leaves open optimal management strategies pending prospective data.
Agrawal et al. (2024) conducted a cohort in Subaortic stenosis (n=484). Older age and baseline NYHA class was evaluated on All-cause mortality and heart failure hospitalizations (HR 1.37, 95% CI 1.12-1.68). Older age (HR 1.37; 95% CI 1.12-1.68 per 10 years) and higher baseline NYHA class (HR 2.48; 95% CI 1.54-3.99) were significantly associated with mortality and heart failure hospitalizations in SAS.
