Calcific aortic valve stenosis constitutes a significant health problem in the elderly. Only a minority of those with potentially operable aortic valve stenosis undergo surgery.

This study aimed at identifying factors influencing aortic valve calcification in old age. Echocardiographic and Doppler characteristics of the aortic valve were compared with possible clinical and biochemical predictors in 501 people aged 75-86 years and in 76 aged 55-71. Slight calcification was seen in 222 people (40%) and severe calcification in 72 (13%); 21 people had moderate or severe aortic stenosis. Age (P = 0.000) and serum parathyroid hormone (P = 0.015) were higher and body mass index lower (P = 0.002) in the presence of aortic valve calcification. In multivariate analysis, age (P = 0.000), hypertension (P = 0.005) and body mass index (P = 0.005) were independent predictors of aortic valve calcification, and age (P = 0.022) and serum ionized calcium (P = 0.037) of valve stenosis. The odds ratio (95% confidence interval) for valve calcification was 1.89 (1.42-2.50) for a 10-year increase in age, 1.74 (1.19-2.55) in the presence of hypertension, and 1.39 (1.10-1.76) for a 5 kg.m-2 decrease in body mass index. Sex, smoking, diabetes, serum lipids and insulin were unrelated to valvular calcification. These data suggest that leanness and a history of hypertension increase the likelihood of senile aortic valve calcification. Calcium metabolism may also be of significance. The mechanisms of these associations deserve further study.

To examine the prevalence, underlying diseases, abnormalities of left ventricular function and prognosis in congestive heart failure (CHF) of old age. Design. A population-based clinical and echocardiographic study with a 4-year mortality followup. Setting. University hospital. 1904, 1909 and 1914 (367 women). Main outcome measures. Presence of CHF by clinical and chest radiograph criteria ; left ventricular size and systolic function by echocardiography ; grade of aortic and mitral valve lesions by Doppler echocardiography ; 4-year total and cardiovascular mortality. Results. Forty-one of 501 participants (8.2 %) had CHF. Ischaemic heart disease (54 %), hypertension (54 %) and moderate-to-severe mitral or aortic valve Subjects. Five hundred and one individuals born in

Results indicate that, the closer cognitive decline, the lower the BP, and suggest that, although LVH is a risk factor of cognitive decline, it loses its predictive value in old age.
