Overview
Aortic stenosis is a major health problem that primarily affects the elderly. The majority of cases of aortic stenosis is due to calcific degeneration. Aortic stenosis tends to affect approximately 2% of patients over the age of 65, 3% of patients over the age of 75, and 4% of patients over the age 85.[1]
Epidemiology and Demographics
Based on the results from the EuroHeart Failure survey programme, 4.8% of patients with acute coronary syndrome had significant valve disease, in particular ischemic mitral regurgitation and calcific aortic stenosis[2] and were associated with poor prognosis.[3]
Age
The prevalence of aortic stenosis increases with age. Less than 1% of all live births exhibit symptoms of severe aortic stenosis. Approximately 2% of patients over the age of 65, 3% of patients over the age of 75, and 4% of patients over the age of 85 have aortic stenosis.[1] The Helsinki Ageing study evaluated 552 patients with aortic valve disease, 53% of which were reported to have calcified aortic valves. The prevalence of critical aortic valve stenosis (aortic valve area = less than 1.2 cm2) was observed to be 2.9% among patients belonging to the 75 to 86 years age group.[4]
Gender
Calcific degenerative aortic stenosis is more common in males [5].
Developed Countries
In North America and Europe, a linear relationship exists between the increase in the incidence of aortic stenosis and the increase in aging population.
