In the elderly, mitral annular calcification (MAC) and aortic valve sclerosis (AVS) are associated with increased cardiovascular morbidity and mortality. Aortic annular calcification (AAC) commonly occurs with MAC. However, the prognostic value of AAC, singly or in combination with MAC and AVS, for incident cardiovascular disease and mortality is unknown. From the Cardiovascular Health Study, we analyzed 3,782 participants (76 +/- 5 years of age, 60\% women) who had an echocardiogram at the 1994 to 1995 examination and who were prospectively followed for an average of 6.6 years (range 0.01 to 8.5). All 3 calcification categories were associated with incident congestive heart failure (MAC: hazard ratio [HR] 1.71, 95\% confidence interval [CI] 1.35 to 2.18, AAC: HR 1.62, 95\% CI 1.28 to 2.06, and AVS: HR 1.50, 95\% CI 1.19 to 1.89) and death. A stronger association with incident cardiovascular disease and mortality was observed with a larger number of calcification categories and with increased MAC severity. Moreover, in the participants with prevalent cardiovascular disease at echocardiographic examination (n = 1,054), MAC and AAC were still associated with cardiovascular mortality (MAC: HR 1.91, 95\% CI 1.04 to 3.50; AAC: HR 2.11, 95\% CI 1.16 to 3.85) even in fully adjusted models. In conclusion, MAC, AAC, and AVS are associated with a significant risk of incident congestive heart failure, cardiovascular and all-cause mortalities, and worse outcome in older patients with preexisting cardiovascular disease. Elderly patients with these findings represent a high-risk group and may require close medical attention.

Mortality risk associated with electrocardiographic (ECG) abnormalities has been commonly reported to be lower in women than in men. We compared coronary heart disease (CHD) and all-cause mortality risk for ECG variables during a mean 9.1-year follow-up in 4,912 participants in the Cardiovascular Health Study who were > or = 65 years of age. The hypothesis was that mortality risk for ECG abnormalities is not lower in women than in men. Five ECG variables were significant mortality predictors in Cox regression models that were adjusted for demographic, clinical, and medication variables. Gender differences were significant and mortality risk was higher in women for ECG estimates of left ventricular mass for both end points and for nondipolar QRS voltage for all-cause mortality. When evaluated simultaneously in multiple ECG variable risk models in subgroups that were stratified by baseline CHD status, no gender difference was significant. In the latter models, ST depression was a strong predictor of CHD mortality in groups with and without previous CHD. Other significant ECG predictors were previous myocardial infarction in the previous CHD group and nondipolar QRS voltage in the CHD-free group. Four ECG abnormalities were significant predictors of all-cause mortality in the CHD-free group, with risk increases of 18\% to 50\%. The risk of all-cause mortality in the previous CHD group was significantly increased for ST depression (by 64\%), the ECG estimate of left ventricular mass (by 48\%), and previous myocardial infarction (by 34\%). In conclusion, we found no evidence that the relative risk of mortality for ECG abnormalities is lower in women than in men.

BACKGROUND AND PURPOSE: Cerebral microvascular disease may be a risk factor for the development of dementia in elderly persons. We describe the association of retinal microvascular signs with cognitive function and dementia among older individuals.

METHODS: In the population-based Cardiovascular Health Study, 2211 persons aged 69 to 97 years at recruitment had retinal photography. Photographs were evaluated for retinopathy (eg, microaneurysms, retinal hemorrhages), focal arteriolar narrowing, arteriovenous nicking, and retinal arteriolar and venular caliber. Cognitive status was determined from the Digit-Symbol Substitution Test and Modified Mini-Mental State Examination. Participants were also further evaluated for the presence of dementia with detailed neuropsychological testing. Persons with a prior stroke or taking antipsychotic or antidepressant medications were excluded.

RESULTS: After adjusting for age, gender, race, field center, education level, internal carotid intima-media thickness, body mass index, hypertension, diabetes, and cigarette smoking status, persons with retinopathy had lower mean Digit-Symbol Substitution Test scores but not Modified Mini-Mental State Examination than those without retinopathy (39 versus 41, P=0.002). In hypertensive persons, retinopathy (multivariable-adjusted OR, 2.10; 95\% CI, 1.04 to 4.24) and focal arteriolar narrowing (OR, 3.02; 95\% CI, 1.51 to 6.02) were associated with dementia. These associations were not present in individuals without hypertension.

CONCLUSIONS: In older persons, our study shows a modest cross-sectional association between retinopathy signs with poorer cognitive function and, in persons with hypertension, with dementia. These data support a possible role of cerebral microvascular disease in the pathogenesis of impaired cognitive function and dementia in older hypertensive persons.
