Aortic stenosis begets aortic stenosis: between a rock and a hard place?
Key result
Baseline aortic stenosis severity was associated with the rate of disease progression, with an average haemodynamic progression of +3±3 mm Hg/year over 2.9 years.
Why the study?
Does baseline aortic stenosis severity predict the rate of haemodynamic progression in patients with mild to moderate disease?
Population
149 patients with largely mild and moderate aortic stenosis (from the discussed study by Nguyen et al.)

Implication
Baseline severity of aortic stenosis appears to predict the rate of future haemodynamic progression, which may help tailor the frequency of echocardiographic surveillance.

Population
149 patients with largely mild and moderate aortic stenosis followed for a mean of 2.9 years to assess disease progression.

Baseline severity of aortic stenosis appears to predict the rate of future haemodynamic progression, which may help tailor the frequency of echocardiographic surveillance.
Cite This Study
Dweck et al. (2015) conducted an editorial in Aortic stenosis (n=149). Baseline aortic stenosis severity was evaluated on Rate of haemodynamic progression (mean gradient). Baseline aortic stenosis severity was associated with the rate of disease progression, with an average haemodynamic progression of +3±3 mm Hg/year over 2.9 years.
