OBJECTIVE: To describe the prevalence of early age-related maculopathy (ARM) and its relation to atherosclerosis, lipids, hypertension, and inflammatory factors in a population studied for cardiovascular disease risk factors and outcomes.

DESIGN: Population-based cohort study.

PARTICIPANTS: A biracial population of 2361 adults (ranging from 69-97 years of age; 1998 whites and 363 blacks) living in four US counties (Allegheny County, Pennsylvania; Forsyth County, North Carolina; Sacramento County, California; and Washington County, Maryland) were examined during the interval from 1997 to 1998.

METHODS: Drusen and other lesions typical of ARM were identified by examining a 45 degrees color fundus photograph of one eye of each participant and classified by means of a modification of the Wisconsin Age-Related Maculopathy Grading System.

MAIN OUTCOME MEASURES: Early ARM.

RESULTS: Early ARM was present in 15.5\% and late ARM in 1.3\% of the cohort. The overall prevalence of any ARM was lower in blacks (9.1\%) compared with whites (18.2\%). While controlling for age, race, gender, and total calories consumed in the diet, factors associated with ARM were cerebral white matter disease as detected by magnetic resonance imaging (odds ratio [OR], 1.50; 95\% confidence interval [CI], 1.05, 2.16, P = 0.027), and lower serum total cholesterol (OR, per 10 mg/dl increase 0.95; 95\% CI, 0.91, 0.98, P = 0.02). There were no associations between hypertension, blood pressure, common carotid artery plaque, or any systemic inflammatory factors studied and early ARM.

CONCLUSIONS: This population-based study documents the higher prevalence of ARM in whites compared with blacks. Although an association was found between signs of white matter disease and early ARM, there was no evidence of an association of ARM with either hypertension or inflammatory factors.

Inflammatory and prothrombotic markers are elevated in individuals with mild to moderate renal disease. It was hypothesized that these markers may also be determinants of the progression of renal disease. The association of six markers-serum C-reactive protein (CRP), white blood cell (WBC) count, fibrinogen, factor VII, albumin, and hemoglobin-with subsequent elevations of creatinine and decline in estimated GFR in the Cardiovascular Health Study, a community-based cohort of elderly individuals, was analyzed. Linear regression was used to determine predictors of an annualized change in serum creatinine as the main outcome. Duration of follow-up was 7 yr for the original cohort and 4 yr for the more recently recruited black cohort. A total of 588 (12.7\%) individuals had a decline in estimated GFR of at least 3 ml/min per yr per 1.73 m(2). Higher CRP (P < 0.001), WBC count (P < 0.001), fibrinogen (P < 0.001), and factor VII (P < 0.001) levels and lower albumin (P < 0.001) and hemoglobin levels (P < 0.001) were associated with a rise in creatinine, after adjusting for age. With additional adjustments for race, gender, baseline creatinine, systolic and diastolic BP, lipid levels, weight, and pack-years smoking, higher CRP, factor VII, fibrinogen, WBC count, and lower albumin and hemoglobin levels remained associated with a rise in creatinine. Similar results were found for decline in estimated GFR. The decline in GFR was greater with increasing number of inflammatory or prothrombotic markers that were above the median (below for hemoglobin and albumin). Inflammatory and prothrombotic markers are predictors for a change in kidney function in elderly individuals. Interventions that reduce inflammation might confer significant cardiovascular and renal benefits.

BACKGROUND: Diabetes mellitus (DM) confers an increased risk of mortality in young and middle-aged individuals and in women. It is uncertain, however, whether excess DM mortality continues beyond age 75 years, is related to type of hypoglycemic therapy, and whether women continue to be disproportionately affected by DM into older age.

METHODS AND FINDINGS: From the Cardiovascular Health Study, a prospective study of 5,888 adults, we examined 5,372 participants aged 65 y or above without DM (91.2\%), 322 with DM treated with oral hypoglycemic agents (OHGAs) (5.5\%), and 194 with DM treated with insulin (3.3\%). Participants were followed (1989-2001) for total, cardiovascular disease (CVD), coronary heart disease (CHD), and non-CVD/noncancer mortality. Compared with non-DM participants, those treated with OHGAs or insulin had adjusted hazard ratios (HRs) for total mortality of 1.33 (95\% confidence interval [CI], 1.10 to 1.62) and 2.04 (95\% CI, 1.62 to 2.57); CVD mortality, 1.99 (95\% CI, 1.54 to 2.57) and 2.16 (95\% CI, 1.54 to 3.03); CHD mortality, 2.47 (95\% CI, 1.89 to 3.24) and 2.75 (95\% CI, 1.95 to 3.87); and infectious and renal mortality, 1.35 (95\% CI, 0.70 to 2.59) and 6.55 (95\% CI, 4.18 to 10.26), respectively. The interaction of age (65-74 y versus > or =75 y) with DM was not significant. Women treated with OHGAs had a similar HR for total mortality to men, but a higher HR when treated with insulin.

CONCLUSIONS: DM mortality risk remains high among older adults in the current era of medical care. Mortality risk and type of mortality differ between OHGA and insulin treatment. Women treated with insulin therapy have an especially high mortality risk. Given the high absolute CVD mortality in older people, those with DM warrant aggressive CVD risk factor reduction.

BACKGROUND: Inflammation may be a causative factor in congestive heart failure (CHF). Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is an inflammation marker associated with vascular risk. One previous study showed an association of Lp-PLA(2) activity with CHF risk, but there were only 94 CHF cases and Lp-PLA(2) antigen, which is available clinically in the United States, was not measured.

METHODS AND RESULTS: We measured baseline Lp-PLA(2) antigen and activity in 3991 men and women without baseline CHF or cardiovascular disease who were participating in the Cardiovascular Health Study, a prospective observational study of adults 65 years or older. Cox proportional hazards models adjusted for age, sex, clinic site, race, low-density and high-density lipoprotein cholesterol, body mass index, systolic and diastolic blood pressure, hypertension, smoking status, pack-years, and diabetes were used to calculate hazard ratios and 95\% CIs for incident CHF. Further models adjusted for coronary disease events during follow-up and C-reactive protein. Eight hundred twenty-nine participants developed CHF during 12.1 years. Adjusted hazard ratios for CHF with Lp-PLA(2) in the fourth compared with the first quartile were 1.44 (95\% CI, 1.16 to 1.79) for Lp-PLA(2) antigen and 1.06 (95\% CI, 0.84 to 1.32) for activity. Adjustment for incident coronary disease attenuated the hazard ratio for Lp-PLA(2) antigen to 1.26 (95\% CI, 1.02 to 1.57), adjustment for C-reactive protein had minimal impact.

CONCLUSIONS: Lp-PLA(2) antigen was associated with risk of future CHF in older people, independent of CHF and coronary risk factors, and partly mediated by coronary disease events. Further clinical and basic research is needed to better understand the role of Lp-PLA(2) in CHF.
