Natural history of aortic valve stenosis of varying severity in the elderly

Abstract

In a population sample of 501 persons aged 75 to 86 years, Doppler echocardiography uncovered moderate or severe aortic valve stenosis in 8.8% of women and 3.6% of men. Severe aortic valve stenosis predicted a four-fold-age- and sex-adjusted risk of death within 4 years of diagnosis, and mortality tended to be increased also with moderate lesions; mild aortic valve stenosis had a favorable outcome.
