Emerging risk factors for atherosclerotic vascular disease: a critical review of the evidence 总被引:24,自引:0,他引:24
Context Atherosclerotic vascular disease is an enormous public health problem. A number of emerging risk factors for atherosclerosis have recently been proposed to help identify high-risk individuals. Objective To review the epidemiological, basic science, and clinical trial evidence concerning 4 emerging risk factors: C-reactive protein, lipoprotein(a), fibrinogen, and homocysteine. Data Sources Using the terms atherosclerosis, cardiovascular disease, risk factors, prevention, screening, C-reactive protein, lipoprotein(a), fibrinogen, and homocysteine, we searched the MEDLINE database from January 1990 to January 2003. Conference proceedings, abstract booklets, bibliographies of pertinent articles and books, and personal files were hand searched to identify additional articles. Study Selection Original investigations and reviews of the epidemiology of atherosclerosis and the association of conventional and novel risk factors with vascular risk were selected. On the basis of the search strategy, 373 relevant studies were identified. Data Extraction A diverse array of studies were examined, including randomized controlled trials, prospective cohort studies, systematic overviews, case-control, cross-sectional, and mechanistic studies. Data extraction was performed by one of the authors. Data Synthesis The available epidemiological and basic science evidence supports, to varying degrees, independent associations between these 4 candidate risk factors and atherosclerotic vascular disease. However, there is relatively little data regarding the additive yield of screening for these factors over that of validated global risk assessment strategies currently in use. Furthermore, controlled intervention studies targeting individuals with these factors for proven risk-reduction therapies, or specifically treating these factors with available therapies, are few. The explanatory power of the major, established cardiovascular risk factors has been systematically underestimated. Conclusions Although C-reactive protein, lipoprotein(a), fibrinogen, and homocysteine are associated with vascular disease risk, their optimal use in routine screening and risk stratification remains to be determined. 相似文献

Poor control of risk factors for vascular disease among adults with previously diagnosed diabetes 总被引:30,自引:2,他引:28
Context Control of blood glucose levels, blood pressure, and cholesterol levels is proven to reduce the risk of vascular disease among individuals with diabetes mellitus; however, the current state of control of these risk factors among individuals in the United States is uncertain. Objectives To examine 1999-2000 national data on control of risk factors for vascular disease among adults with previously diagnosed diabetes and to assess trends during the past decade. Design, Setting, and Participants Review of data from the Third National Health and Nutrition Examination Survey (NHANES III, conducted 1988-1994) and NHANES 1999-2000, cross-sectional surveys of a nationally representative sample of the noninstitutionalized civilian US population. Participants were adults aged 20 years and older with previously diagnosed diabetes who participated in both the interview and examination in either NHANES III (n = 1265) or NHANES 1999-2000 (n = 441). Main Outcome Measures Levels of glycosylated hemoglobin (HbA1c), blood pressure, and total serum cholesterol in reference to target goals. Results Compared with NHANES III, participants with previously diagnosed diabetes in NHANES 1999-2000 were similar by age and sex, were less likely to be non-Hispanic white, were diagnosed at an earlier age, had a higher body mass index, and were more likely to use insulin in combination with oral agents. In NHANES 1999-2000, only 37.0% of participants achieved the target goal of HbA1c level less than 7.0% and 37.2% of participants were above the recommended "take action" HbA1c level of greater than 8.0%; these percentages did not change significantly from NHANES III (P = .11 and P = .87, respectively). Only 35.8% of participants achieved the target of systolic blood pressure (SBP) less than 130 mm Hg and diastolic blood pressure (DBP) less than 80 mm Hg, and 40.4% had hypertensive blood pressure levels (SBP =" BORDER="0">140 or DBP =" BORDER="0">90 mm Hg). These percentages did not change significantly from NHANES III (P = .10 and P = .56, respectively). Over half (51.8%) of the participants in NHANES 1999-2000 had total cholesterol levels of 200 mg/dL or greater (vs 66.1% in NHANES III; P<.001). In total, only 7.3% (95% confidence interval, 2.8%-11.9%) of adults with diabetes in NHANES 1999-2000 attained recommended goals of HbA1c level less than 7%, blood pressure less than 130/80 mm Hg, and total cholesterol level less than 200 mg/dL (5.18 mmol/L). Conclusion Further public health efforts are needed to control risk factors for vascular disease among individuals with diagnosed diabetes. 相似文献

Despite a general decline in mortality rates in recent decades, these rates are substantially higher among lower socioeconomic groups. To determine target groups for preventive health promotion programs, the prevalence of risk factors for cardiovascular disease by socioeconomic group in Canadian adults aged 20 to 69 years was examined through comparison of estimates from the 1978-79 Canada Health Survey, the 1981 Canada Fitness Survey and the labour force smoking surveys of 1975 and 1983. Level of education was used as a measure of socioeconomic status. The risk factors considered were cigarette smoking, overweight, obesity, elevated diastolic blood pressure, physical inactivity, excessive alcohol consumption, elevated serum cholesterol level, diabetes mellitus and the conjoint use of oral contraceptives and cigarettes. The prevalence of the risk factors tended to be higher among men and women with a low level of education. The results were consistent with those of recent Canadian studies showing that both men and women in lower socioeconomic groups are more likely to die from cardiovascular disease. 相似文献

Context Poor public knowledge of stroke warning signs and risk factors limits effective stroke intervention and prevention. Objective To examine temporal trends in public knowledge of stroke warning signs and risk factors. Design and Setting Population-based random-digit telephone survey conducted in July-November 2000 among individuals in the greater Cincinnati, Ohio, region. Participants A total of 2173 survey respondents (69% response rate) were randomly identified based on their demographic similarities to the ischemic stroke population with regard to age, race, and sex. Main Outcome Measures Spontaneous recall of at least 1 important stroke warning sign and 1 established stroke risk factor in comparison with findings from the same survey in 1995. Results In 2000, 70% of respondents correctly named at least 1 established stroke warning sign vs 57% in 1995 (P<.001), and 72% correctly named at least 1 established stroke risk factor vs 68% in 1995. Groups of individuals with the highest risk and incidence of stroke, such as persons at least 75 years old, blacks, and men, were the least knowledgeable about warning signs and risk factors. Television was the most frequently cited source of knowledge, 32% in 2000 vs 24% in 1995 (P<.001). Conclusions Public knowledge of stroke warning signs within the greater Cincinnati region has significantly improved from 1995 to 2000, although knowledge of stroke risk factors did not improve significantly during the same time period. Public education efforts must continue and should focus on groups at the highest risk of stroke. 相似文献
