OBJECTIVES: To compare the risk of congestive heart failure (CHF) in elderly individuals treated with any peripheral alpha-1 antagonist for hypertension with any thiazide, test whether the risk persists in subjects without cardiovascular disease (CVD) at baseline, and examine CHF risk in normotensive men with prostatism treated with alpha antagonists.

DESIGN: Prospective cohort study.

SETTING: Four U.S. sites: Washington County, Maryland; Allegheny County, Pennsylvania; Sacramento County, California; and Forsyth County, North Carolina.

PARTICIPANTS: A total of 5,888 community-dwelling subjects aged 65 and older.

MEASUREMENTS: Adjudicated incident CHF.

RESULTS: The 3,105 participants with treated hypertension were at risk for CHF; 22\% of men and 8\% of women took alpha antagonists during follow-up. The age-adjusted risk of CHF in those receiving monotherapy treated with alpha antagonists was 1.90 (95\% confidence interval=1.03-3.50) compared with thiazides. In subjects without CVD at baseline receiving monotherapy, women taking an alpha antagonist had a 3.6 times greater age-adjusted risk of CHF, whereas men had no difference in risk. Adjustment for systolic blood pressure attenuated statistical differences in risk. There were 930 men without hypertension at risk for CHF; 5\% used alpha antagonists during follow-up, with no observed increase in CHF risk.

CONCLUSION: Subjects receiving alpha antagonist monotherapy for hypertension had a two to three times greater risk of incident CHF, also seen in lower-risk subjects, but differences in blood pressure control partly explained this.

OBJECTIVES: Our aim was to investigate the relation between fish consumption and incidence of congestive heart failure (CHF).

BACKGROUND: The incidence and health burden of CHF are rising, particularly in older persons. Although n-3 fatty acids have effects that could favorably influence risk of CHF, the relation between fish intake and CHF incidence is unknown.

METHODS: Among 4,738 adults age > or =65 years and free of CHF at baseline in 1989-90, usual dietary intake was assessed using a food frequency questionnaire. In a participant subsample, consumption of tuna or other broiled or baked fish, but not fried fish, correlated with plasma phospholipid n-3 fatty acids. Incidence of CHF was prospectively adjudicated.

RESULTS: During 12 years{\textquoteright} follow-up, 955 participants developed CHF. In multivariate-adjusted analyses, tuna/other fish consumption was inversely associated with incident CHF, with 20\% lower risk with intake 1 to 2 times/week (hazard ratio [HR] = 0.80, 95\% confidence interval [CI] = 0.64 to 0.99), 31\% lower risk with intake 3 to 4 times/week (HR = 0.69, 95\% CI = 0.52 to 0.91), and 32\% lower risk with intake > or =5 times/week (HR = 0.68, 95\% CI = 0.45 to 1.03), compared with intake <1 time/month (p trend = 0.009). In similar analyses, fried fish consumption was positively associated with incident CHF (p trend = 0.01). Dietary long-chain n-3 fatty acid intake was also inversely associated with CHF (p trend = 0.009), with 37\% lower risk in the highest quintile of intake (HR = 0.73, 95\% CI = 0.57 to 0.94) compared with the lowest.

CONCLUSIONS: Among older adults, consumption of tuna or other broiled or baked fish, but not fried fish, is associated with lower incidence of CHF. Confirmation in additional studies and evaluation of potential mechanisms is warranted.

OBJECTIVES: We investigated the association between alcohol consumption and incident congestive heart failure (CHF) both overall and after adjusting for incident myocardial infarction (MI).

BACKGROUND: Moderate alcohol consumption has been associated with lower risk of CHF and MI.

METHODS: The Cardiovascular Health study, a prospective cohort study of cardiovascular disease risk factors and outcomes, followed 5,888 subjects > or =65 years old for 7 to 10 years. Cox models were used to estimate the adjusted risk of CHF by reported alcohol consumption.

RESULTS: There were 5,595 subjects at baseline at risk for incident CHF with alcohol data and 1,056 events during follow-up. Compared with abstainers, the adjusted risk of CHF was lower among subjects who reported consuming 1 to 6 drinks per week (hazard ratio [HR] 0.82, 95\% confidence interval [CI] 0.67 to 1.00, p = 0.05) and 7 to 13 drinks per week (HR 0.66, 95\% CI 0.47 to 0.91, p = 0.01). Time-dependent adjustment for incident MI altered only slightly the association between moderate alcohol consumption and CHF (for 1 to 6 drinks per week, HR 0.84, 95\% CI 0.65 to 1.04; for 7 to 13 drinks per week, HR 0.69, 95\% CI 0.49 to 0.99). Baseline former drinkers had a higher risk of CHF than abstainers (HR 1.51, p < 0.01), but those who quit during the study did not have a higher risk (HR 0.83, 95\% CI 0.66 to 1.03).

CONCLUSIONS: Moderate alcohol use is associated with a lower risk of incident CHF among older adults, even after accounting for incident MI and other factors.
