Usefulness of desirable lifestyle factors to attenuate the risk of heart failure among offspring whose parents had myocardial infarction before age 55 years.
ABSTRACT Heart failure (HF) is one of the leading causes of hospitalization and death in the United States and throughout Europe. Although a higher risk for HF with antecedent myocardial infarction (MI) has been reported in offspring whose parents had MIs before age 55 years, it is unclear whether adherence to healthful behaviors can mitigate that risk. The aim of the present study was therefore to prospectively examine if adherence to healthy weight, regular exercise, moderate alcohol consumption, and abstinence from smoking can attenuate such increased HF risk. Information on parental history of MI and lifestyle factors was collected using questionnaires. Subjects adhering to ≥3 healthy lifestyle factors were classified as having good versus poor lifestyle scores. Incident HF was assessed via yearly follow-up questionnaires and validated in a subsample. During an average follow up of 21.7 ± 6.5 years, 1,323 new HF cases (6.6%), of which 190 (14.4%) were preceded by MI, occurred. Compared to subjects with good lifestyle scores and no parental histories of premature MI, multivariate adjusted hazard ratios for incident HF with antecedent MI were 3.21 (95% confidence interval 1.74 to 5.91) for subjects with good lifestyle score and parental histories of premature MI, 1.52 (95% confidence interval 1.12 to 2.07) for those with poor lifestyle score and no parental histories of premature MI, and 4.60 (95% confidence interval 2.55 to 8.30) for those with poor lifestyle scores and parental histories of premature MI. In conclusion, our data suggest that even in subjects at higher risk for HF because of genetic predisposition, adherence to healthful lifestyle factors may attenuate such an elevated HF risk.

ABSTRACT: Many lifestyle-related risk factors for coronary heart disease have been identified, but little is known about their effect on the risk of disease when they are considered together. We followed 84,129 women participating in the Nurses' Health Study who were free of diagnosed cardiovascular disease, cancer, and diabetes at base line in 1980. Information on diet and lifestyle was updated periodically. During 14 years of follow-up, we documented 1128 major coronary events (296 deaths from coronary heart disease and 832 nonfatal infarctions). We defined subjects at low risk as those who were not currently smoking, had a body-mass index (the weight in kilograms divided by the square of the height in meters) under 25, consumed an average of at least half a drink of an alcoholic beverage per day, engaged in moderate-to-vigorous physical activity (which could include brisk walking) for at least half an hour per day, on average, and scored in the highest 40 percent of the cohort for consumption of a diet high in cereal fiber, marine n-3 fatty acids, and folate, with a high ratio of polyunsaturated to saturated fat, and low in trans fat and glycemic load, which reflects the extent to which diet raises blood glucose levels. Many of the factors were correlated, but each independently and significantly predicted risk, even after further adjustment for age, family history, presence or absence of diagnosed hypertension or diagnosed high cholesterol level, and menopausal status. Women in the low-risk category (who made up 3 percent of the population) had a relative risk of coronary events of 0.17 (95 percent confidence interval, 0.07 to 0.41) as compared with all the other women. Eighty-two percent of coronary events in the study cohort (95 percent confidence interval, 58 to 93 percent) could be attributed to lack of adherence to this low-risk pattern. Among women, adherence to lifestyle guidelines involving diet, exercise, and abstinence from smoking is associated with a very low risk of coronary heart disease.New England Journal of Medicine 08/2000; 343(1):16-22. · 54.42 Impact Factor

ABSTRACT: Healthy lifestyle choices such as eating a prudent diet, exercising regularly, managing weight, and not smoking may substantially reduce coronary heart disease (CHD) risk by improving lipids, blood pressure, and other risk factors. The burden of CHD that could be avoided through adherence to these modifiable lifestyle factors has not been assessed among middle-aged and older US men, specifically men taking medications for hypertension or hypercholesterolemia. We prospectively monitored 42 847 men in the Health Professionals Follow-up Study, 40 to 75 years of age and free of disease in 1986. Lifestyle factors were updated through self-reported questionnaires. Low risk was defined as (1) absence of smoking, (2) body mass index <25 kg/m2, (3) moderate-to-vigorous activity > or = 30 min/d, (4) moderate alcohol consumption (5 to 30 g/d), and (5) the top 40% of the distribution for a healthy diet score. Over 16 years, we documented 2183 incident cases of CHD (nonfatal myocardial infarction and fatal CHD). In multivariate-adjusted Cox proportional hazards models, men who were at low risk for 5 lifestyle factors had a lower risk of CHD (relative risk: 0.13; 95% confidence interval [CI]: 0.09, 0.19) compared with men who were at low risk for no lifestyle factors. Sixty-two percent (95% CI: 49%, 74%) of coronary events in this cohort may have been prevented with better adherence to these 5 healthy lifestyle practices. Among men taking medication for hypertension or hypercholesterolemia, 57% (95% CI: 32%, 79%) of all coronary events may have been prevented with a low-risk lifestyle. Compared with men who did not make lifestyle changes during follow-up, those who adopted > or = 2 additional low-risk lifestyle factors had a 27% (95% CI: 7%, 43%) lower risk of CHD. A majority of CHD events among US men may be preventable through adherence to healthy lifestyle practices, even among those taking medications for hypertension or hypercholesterolemia.Circulation 08/2006; 114(2):160-7. · 14.95 Impact Factor

ABSTRACT: Heart failure (HF) is the leading cause of hospitalization among the elderly, and 1 in 5 adults aged 40 years will develop HF in their lifetime. Data on the effects of moderate alcohol consumption on the risk of HF have been sparse and inconsistent. This study sought to evaluate the association between moderate alcohol consumption and incident HF. A total of 21,601 participants of the Physicians' Health Study I who were free of HF and provided data on alcohol intake at baseline were prospectively followed up from 1982 to 2005. Incident HF cases were ascertained through annual follow-up questionnaires and validated with the use of Framingham criteria. During an average follow-up of 18.4 years, 904 incident cases of HF occurred. The crude incidence rates of HF were 25.0, 20.0, 24.3, and 20.6 cases per 10,000 person-years for alcohol categories of <1, 1 to 4, 5 to 7, and >7 drinks per week, respectively. Corresponding hazard ratios (95% CI) were 1.0 (reference), 0.90 (0.76 to 1.07), 0.84 (0.71 to 0.99), and 0.62 (0.41 to 0.96), respectively, with P for trend=0.012 adjusted for age, body mass index, smoking, and history of valvular heart disease. There was no evidence for a strong association between moderate alcohol consumption and HF without antecedent coronary artery disease. Although heavy drinking should be discouraged, our data indicate that moderate drinking may lower the risk of HF. The lack of an association between moderate alcohol intake and HF without antecedent coronary artery disease suggests that possible benefits of moderate drinking on HF may be mediated through beneficial effects of alcohol on coronary artery disease.Circulation 02/2007; 115(1):34-9. · 14.95 Impact Factor
