Weight loss, muscle strength, and angiotensin-converting enzyme inhibitors in older adults with congestive heart failure or hypertension.

OBJECTIVES: To determine whether angiotensin-converting enzyme (ACE) inhibitor use may be associated with weight maintenance and sustained muscle strength (measured by grip strength) in older adults. DESIGN: Data from the Cardiovascular Health Study (CHS), a community-based prospective cohort study of 5,888 older adults, were used. SETTING: Subjects were recruited from four U.S. sites beginning in 1989; this analysis included data through 2001. PARTICIPANTS: CHS participants with congestive heart failure (CHF) or treated hypertension. MEASUREMENTS: The exposure, current ACE inhibitor use, was ascertained by medication inventory at annual clinic visits; the outcomes were weight change and grip-strength change during the following year. Multivariate linear regression was used, accounting for correlations between observations on the same participant over time. RESULTS: The average annual weight change was -0.38 kg in 2,834 participants (14,443 person-years) with treated hypertension and -0.62 kg in 342 participants (980 person-years) with CHF. ACE inhibitor use was associated with less annual weight loss after adjustment for potential confounders: a difference of 0.17 kg (95% confidence interval (CI)=0.05-0.29) in those with treated hypertension and 0.29 kg (95% CI=-0.25-0.83) in those with CHF. There was no evidence of association between ACE inhibitor use and grip-strength change. CONCLUSION: ACE inhibitor use may be associated with weight maintenance, but not maintenance of muscle strength, in older adults with treated hypertension.

Incidence, manifestations, and predictors of worsening white matter on serial cranial magnetic resonance imaging in the elderly: the Cardiovascular Health Study.

BACKGROUND AND PURPOSE: Magnetic resonance imaging (MRI) scans in the elderly commonly show white matter findings that may raise concerns. We sought to document incidence, manifestations, and predictors of worsening white matter grade on serial imaging. METHODS: The Cardiovascular Health Study is a population-based, longitudinal study of 5888 people aged 65 years and older, of whom 1919 have had extensive initial and follow-up evaluations, including 2 MRI scans separated by 5 years. Scans were read without clinical information in standard side-by-side fashion to determine worsening white matter grade. RESULTS: Worsening was evident in 538 participants (28%), mostly (85%) by 1 grade. Although similar at initial scan, participants with worsening white matter grade, compared with those without, experienced greater decline on modified Mini-Mental State examination and Digit-Symbol Substitution test (both P< or =0.001) after controlling for potential confounding factors, including occurrence of transient ischemic attack or stroke between scans. Independent predictors of worsening white matter grade included cigarette smoking before initial scan and infarct on initial scan. Otherwise, predictors differed according to white matter grade on initial scan. For low initial grade, increased age, increased diastolic blood pressure, increased high-density lipoprotein cholesterol, and decreased low-density lipoprotein cholesterol were associated with increased risk of worsening. For high initial grade, any cardiovascular disease and low ankle-arm index were associated with decreased risk of worsening, whereas use of diuretics and statins were associated with increased risk. CONCLUSIONS: Worsening white matter grade on serial MRI scans in elderly is common, is associated with cognitive decline, and has complex relations with cardiovascular risk factors.

Potential for conflict of interest in the evaluation of suspected adverse drug reactions: use of cerivastatin and risk of rhabdomyolysis.

CONTEXT: In recent years, US patients have increasingly been the first to receive new medications, some of which are subsequently discovered to have suspected adverse drug reactions (SADRs). As a result, the challenge of early detection has largely shifted to the US postmarketing systems. OBJECTIVE: To review the association between the use of cerivastatin sodium and the risk of rhabdomyolysis in an effort to illustrate the operation and limitations of the current US postmarketing safety-surveillance system. DATA SOURCES AND SELECTION: For the published literature, we used previous reviews and MEDLINE searches from all years through 2003. For the unpublished literature, we used internal company documents that have become part of the public record during a trial in Nueces County, Texas. DATA SYNTHESIS: In the published literature, cerivastatin was associated with much larger risks of rhabdomyolysis than other statins. Although only a small percentage of cerivastatin users also took gemfibrozil, approximately half of the case reports of rhabdomyolysis occurred in users of this combination therapy, and a cerivastatin-gemfibrozil interaction was supported by the results of a 3-day pharmacokinetic study. In internal company documents, multiple case reports suggested a drug-drug interaction within approximately 100 days of the launch in 1998; however, the company did not add a contraindication about the concomitant use of cerivastatin and gemfibrozil to the package insert for more than 18 months. Unpublished data available in July 1999 also suggested an increased risk of rhabdomyolysis associated with high doses of cerivastatin monotherapy. In late 1999 and early 2000, company scientists conducted high-quality analyses of the US Food and Drug Administration adverse event reporting system data. These analyses suggested that compared with atorvastatin calcium, cerivastatin monotherapy substantially increased the risk of rhabdomyolysis. To our knowledge, these findings were not disseminated or published. The company continued to conduct safety studies, some of them inadequately designed to assess the risk of rhabdomyolysis, until cerivastatin was removed from the market in August 2001. CONCLUSIONS: Despite limitations of the available data, the asymmetry between the information available to the company and the information available to patients and physicians seems striking. A subjective element is present in the effort to infer whether or not the occurrence of untoward outcomes in users of a particular drug was actually the consequence of the use of that drug, and, under the current system, a pharmaceutical company's appraisal of SADRs may be influenced by economic considerations. Such an appraisal would best be made by an independent group. The US Congress should mandate and provide adequate support for independent reviews and analysis of postmarketing data.

Balancing commercial and public interests.

Alarge number of randomized clinical trials with important health outcomes are completed each year. Those with favorable findings are typically reported and published rapidly, while the publication of those with unfavorable results is often delayed or given a positive "spin." This observation applies primarily to industry-sponsored trials. Our objectives are to discuss the responsibility of pharmaceutical firms to the public with respect to timely, complete, and unbiased information from all randomized clinical trials and to propose solutions for improvements. We believe that in addition to financial obligations to their shareholders, pharmaceutical companies have social responsibilities to the public and to health care providers. However, private markets do not reward or compel optimal disclosure of drug safety or inferiority information on a voluntary basis.A problem which has not previously been identified relates to non-comparability of drugs. A case report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) illustrates how public interests may be violated due to failure to inform about drug inferiority. The current system for dissemination of relevant medical information could be improved if all involved parties collaborated fully. However, full disclosure of trial results is unlikely when research results are unfavorable to the firm. We conclude that expanded government regulations will be required for a satisfactory solution to the problem.

ALLHAT: setting the record straight.

The findings of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) have generated worldwide reaction from clinicians and researchers, including a recent commentary in this journal. Such response was expected for a trial of ALLHAT's size and scope, especially since its results challenged some widely held beliefs. This paper reviews key aspects of the ALLHAT design, analyses, findings, and conclusions to provide a perspective on the commentary about the trial's results and implications for clinical practice. Several of the most frequent comments regarding the study's results are addressed, particularly with respect to heart failure and diabetes outcomes. Responses to these comments reinforce the investigators' original conclusion that thiazide-type diuretics should remain the preferred first-step drug class for treating hypertension and should generally be a part of any multidrug regimen.

From knowledge to practice in chronic cardiovascular disease: a long and winding road.

Although clinical practices evolve over time, the translation of specific research evidence into clinical practice is unpredictable, inconsistent, and complex. In this paper, we use examples from chronic cardiovascular conditions to: 1). highlight two types of care gaps; 2). describe the most common potential barriers to the application of evidence into clinical care; and 3). outline which of the strategies for translating evidence into clinical care have been shown to be ineffective, which strategies have been shown to be effective and to describe some untested approaches that hold promise.

Impact of clinical trial results on national trends in alpha-blocker prescribing, 1996-2002.

CONTEXT: Research on factors that influence prescribing patterns and the extent of change produced by clinical trial findings is limited. OBJECTIVE: To examine the changes in prescribing of alpha-blockers for hypertension treatment before and after the April 2000 publication of the unfavorable Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) early termination involving the study's doxazosin mesylate arm. Changes in prescribing were considered in the context of other potential concurrent influences on medication use between 1996 and 2002, including changes in alpha-blocker drug prices, generic conversion, drug promotion, and competition. DESIGN, SETTING, AND PATIENTS: Using 2 national pharmaceutical market research reports published by IMS HEALTH, alpha-blocker prescription orders reported in the National Prescription Audit-a random computerized sample of about 20 000 of 29 000 retail, independent, and mail order pharmacies and mass merchandise and discount houses--and office-based physician alpha-blocker prescribing patterns reported in the National Disease and Therapeutic Index--a random stratified sample of about 3500 physician offices--were tracked. OUTCOME MEASURES: Trends in physician-reported use of alpha-blockers and alpha-blocker prescribing and dispensing by US pharmacies. RESULTS: There were steady increases in alpha-blocker new prescriptions, dispensed prescriptions, and physician drug use from 1996 through 1999. There was a moderate reversal in these trends following ALLHAT early termination and subsequent publications in early 2000. Between 1999 and 2002, new annual alpha-blocker prescription orders declined by 26% (from 5.15 million to 3.79 million), dispensed prescriptions by 22% (from 17.2 million to 13.4 million), and physician-reported drug use by 54% (from 2.26 million to 1.03 million). Other potential influences did not appear to have contributed significantly to this decline although cessation of alpha-blocker marketing may have hastened the decline. CONCLUSIONS: Modest yet statistically significant declines in the use of doxazosin and other alpha-blockers coincided with the early termination of the ALLHAT doxazosin arm. Although physicians responded to this new evidence, strategies to augment the impact of clinical trials on clinical practice are warranted.

Beyond hypertension toward guidelines for cardiovascular risk reduction.

BACKGROUND: Most current clinical guidelines focus primarily on the management of individual cardiovascular risk factors, such as high blood pressure (BP), hypercholesterolemia, or diabetes. A more appropriate clinical approach to reducing cardiovascular disease risk would be based on a comprehensive evaluation of risk profile, and accurate stratification of global (absolute) risk in individual patients. We propose that global risk should be used as the main determinant of whom to treat, how to treat, and how much to treat. METHODS: In this article we use a series of case studies to demonstrate the implications of replacing the traditional "single risk factor-based" approach to managing hypertension by one based on global risk assessment. In some situations patients with mildly elevated BP levels would not be recommended for antihypertensive drug treatment whereas others with lower BP would be treated, depending upon the entire risk profile. CONCLUSION: We propose to replace the single risk factor-based approach with the assessment of global cardiovascular risk, both in the clinical management of individual patients and in guidelines.

Creatinine levels and cardiovascular events in women with heart disease: do small changes matter?

BACKGROUND: Small changes in creatinine levels have been incrementally associated with increased risk for heart failure morbidity, but their association with cardiovascular events has not been evaluated in persons with established coronary heart disease (CHD). METHODS: This was an observational study from the Heart and Estrogen/Progestin Replacement Study (HERS) and the HERS-II follow-up study. Participants were 2,763 postmenopausal women with CHD who were followed up for a mean of 4.1 years during HERS and an additional 2.7 years during HERS-II. We evaluated the association of worsened renal function (creatinine level increase > or = 0.3 mg/dL [> or =26.5 micromol/L]) during HERS with CHD outcomes (nonfatal myocardial infarction and CHD death) that occurred during HERS-II. RESULTS: Only 194 participants (9%) had worsened renal function during HERS, and they were characterized by a greater prevalence of diabetes, lower high-density lipoprotein cholesterol and higher triglyceride levels, and increased rate of cardiovascular events during HERS (all P < 0.01). After adjustment for only baseline creatinine levels, worsened renal function was associated with HERS-II CHD events (relative hazard [RH], 1.54; 95% confidence interval [CI], 1.04 to 2.29). After adjustment for baseline characteristics, HERS cardiovascular events, and medication use, worsened renal function was no longer associated with CHD events (RH, 1.08; 95% CI, 0.70 to 1.67). However, baseline creatinine levels from HERS were remarkably strong predictors of HERS-II events. CONCLUSION: Although baseline renal function was among the strongest predictors of CHD events during 7 years of HERS follow-up, we found no significant association of worsened renal function with cardiovascular outcomes after adjustment for cardiovascular risk factors and interim events.

The association between lipid levels and the risks of incident myocardial infarction, stroke, and total mortality: The Cardiovascular Health Study.

OBJECTIVES: To assess the association between lipid levels and cardiovascular events in older adults. DESIGN: A prospective population-based study. SETTING: Four field centers in U.S. communities. PARTICIPANTS: A total of 5,201 adults aged 65 and older living in U.S. communities, plus a recruitment of 687 African Americans 3 years later. MEASUREMENTS: Fasting lipid measures included low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol, and triglycerides. RESULTS: At baseline, 1,954 men and 2,931 women were at risk for an incident myocardial infarction (MI) or stroke. During an average 7.5-year follow-up, 436 subjects had a coronary event, 332 had an ischemic stroke, 104 a hemorrhagic stroke, and 1,096 died. After adjustment, lipid measures were not major predictors of the outcomes of MI, ischemic stroke, hemorrhagic stroke, and total mortality. For total cholesterol and LDL-C, the associations with MI and ischemic stroke were only marginally significant. HDL-C was inversely associated with MI risk (hazard ratio=0.85 per standard deviation of 15.7 mg/dL, 95% confidence interval=0.76-0.96). For the outcome of ischemic stroke, high levels of HDL-C were associated with a decreased risk in men but not women. Lipid measures were generally only weakly associated with the risks of hemorrhagic stroke or total mortality. CONCLUSION: In this population-based study of older adults, most lipid measures were weakly associated with cardiovascular events. The association between low HDL-C and increased MI risk was nonetheless strong and consistent.

Risk of congestive heart failure in an elderly population treated with peripheral alpha-1 antagonists.

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.

The apoB/apoA-I ratio is better than the cholesterol ratios to estimate the balance between plasma proatherogenic and antiatherogenic lipoproteins and to predict coronary risk.

BACKGROUND: The apolipoprotein B (apoB)/apoA-I ratio represents the balance of proatherogenic and antiatherogenic lipoproteins. The purpose of this study was to determine whether the apoB/apoA-I ratio was superior to any of the cholesterol ratios - total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C), low-density lipoprotein cholesterol (LDL-C)/HDL-C and non-HDL-C/HDL-C - in predicting the risk of coronary disease. Moreover, we examined whether any lipids, lipoproteins or cholesterol ratios add significant predictive information beyond that provided by the apoB/apoA-I ratio. METHODS: Plasma lipids, lipoproteins, apoB, and apoA-I were measured in 69,030 men and 57,168 women above 40 years of age. After a mean follow-up of 98 months, 1183 men and 560 women had died from a myocardial infarction in this prospective apolipoprotein-related mortality risk (AMORIS) study. RESULTS: High apoB and a high apoB/apoA-I ratio were strongly related to increased coronary risk, while high apoA-I was inversely related to risk. The apoB/apoA-I ratio was superior to any of the cholesterol ratios in predicting risk. This advantage was most pronounced in subjects with LDL-C levels <3.6 mmol/l. Addition of lipids, lipoproteins or any cholesterol ratio to apoB/apoA-I in risk models did not further improve the strong predictive value of apoB/apoA-I. CONCLUSIONS: These results indicate that the apoB/apoA-I ratio is at present the best single lipoprotein-related variable to quantitate coronary risk. Given the additional advantages apolipoproteins possess - fasting samples are not required, apoB/apoA-I is a better index of the adequacy of statin therapy than LDL-C, and the measurement of apoB and apoA-I are standardized, whereas LDL-C and HDL-C are not - there would appear to be considerable advantage to integrating apolipoproteins into clinical practice.

Differences in medical care and disease outcomes among black and white women with heart disease.

BACKGROUND: The risk of cardiovascular mortality is higher among black women than white women, and the reasons for this disparity are largely unexplored. We sought to evaluate differences in medical care and clinical outcomes among black and white women with established coronary artery disease. METHODS AND RESULTS: Among the 2699 women enrolled in the Heart and Estrogen/progestin Replacement Study (HERS), we used Cox proportional hazards models to determine the association of race with risk of coronary heart disease (CHD) events independent of major cardiovascular risk factors or medical therapies. During an average of 4.1 years of follow-up, CHD events were twice as likely in black compared with white women (6.4 versus 3.1 per 100 person-years, hazard ratio, 2.1; 95% confidence interval, 1.5 to 2.8; P<0.001). Black women had higher rates of hypertension, diabetes, and hypercholesterolemia, yet were less likely to receive aspirin or statins. Black women less often had optimal blood pressure (56% versus 63%; P=0.01) and LDL cholesterol (30% versus 38%; P=0.04) control at baseline and during follow-up. After adjusting for these and other differences, black women still had >50% higher CHD event risk (hazard ratio, 1.52; 95% confidence interval, 1.1 to 2.1; P=0.03). CONCLUSIONS: In a large cohort of women with heart disease, black women less often received appropriate preventive therapy and adequate risk factor control despite a greater CHD event risk. Interventions to improve appropriate therapy and risk factor control in all women, and especially black women, are needed.

Health outcomes associated with various antihypertensive therapies used as first-line agents: a network meta-analysis.

CONTEXT: Establishing relative benefit or harm from specific antihypertensive agents is limited by the complex array of studies that compare treatments. Network meta-analysis combines direct and indirect evidence to better define risk or benefit. OBJECTIVE: To summarize the available clinical trial evidence concerning the safety and efficacy of various antihypertensive therapies used as first-line agents and evaluated in terms of major cardiovascular disease end points and all-cause mortality. DATA SOURCES AND STUDY SELECTION: We used previous meta-analyses, MEDLINE searches, and journal reviews from January 1995 through December 2002. We identified long-term randomized controlled trials that assessed major cardiovascular disease end points as an outcome. Eligible studies included both those with placebo-treated or untreated controls and those with actively treated controls. DATA EXTRACTION: Network meta-analysis was used to combine direct within-trial between-drug comparisons with indirect evidence from the other trials. The indirect comparisons, which preserve the within-trial randomized findings, were constructed from trials that had one treatment in common. DATA SYNTHESIS: Data were combined from 42 clinical trials that included 192 478 patients randomized to 7 major treatment strategies, including placebo. For all outcomes, low-dose diuretics were superior to placebo: coronary heart disease (CHD; RR, 0.79; 95% confidence interval [CI], 0.69-0.92); congestive heart failure (CHF; RR, 0.51; 95% CI, 0.42-0.62); stroke (RR, 0.71; 0.63-0.81); cardiovascular disease events (RR, 0.76; 95% CI, 0.69-0.83); cardiovascular disease mortality (RR, 0.81; 95% CI, 0.73-0.92); and total mortality (RR, 0.90; 95% CI, 0.84-0.96). None of the first-line treatment strategies-beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers (CCBs), alpha-blockers, and angiotensin receptor blockers-was significantly better than low-dose diuretics for any outcome. Compared with CCBs, low-dose diuretics were associated with reduced risks of cardiovascular disease events (RR, 0.94; 95% CI, 0.89-1.00) and CHF (RR, 0.74; 95% CI, 0.67-0.81). Compared with ACE inhibitors, low-dose diuretics were associated with reduced risks of CHF (RR, 0.88; 95% CI, 0.80-0.96), cardiovascular disease events (RR, 0.94; 95% CI, 0.89-1.00), and stroke (RR, 0.86; 0.77-0.97). Compared with beta-blockers, low-dose diuretics were associated with a reduced risk of cardiovascular disease events (RR, 0.89; 95% CI, 0.80-0.98). Compared with alpha-blockers, low-dose diuretics were associated with reduced risks of CHF (RR, 0.51; 95% CI, 0.43-0.60) and cardiovascular disease events (RR, 0.84; 95% CI, 0.75-0.93). Blood pressure changes were similar between comparison treatments. CONCLUSIONS: Low-dose diuretics are the most effective first-line treatment for preventing the occurrence of cardiovascular disease morbidity and mortality. Clinical practice and treatment guidelines should reflect this evidence, and future trials should use low-dose diuretics as the standard for clinically useful comparisons.

Risk factors and secondary prevention in women with heart disease: the Heart and Estrogen/progestin Replacement Study.

BACKGROUND: Risk factors for coronary heart disease events have most commonly been evaluated in healthy men. OBJECTIVE: To assess risk factors, event rates, and use of secondary prevention treatments in women with preexisting coronary disease. DESIGN: A prospective cohort of clinical trial participants. SETTING: 20 U.S. clinical centers. PARTICIPANTS: 2763 postmenopausal women with known coronary disease in the Heart and Estrogen/progestin Replacement Study (HERS). MEASUREMENTS: Myocardial infarction or death from coronary heart disease. RESULTS: On multivariable analysis, the researchers found 11 risk factors: 6 noted by history (nonwhite ethnicity, lack of exercise, treated diabetes, angina, congestive heart failure, and more than one previous myocardial infarction) and 5 that were measured (blood pressure, low-density lipoprotein cholesterol level, high-density lipoprotein cholesterol level, lipoprotein(a) level, and creatinine clearance). The annual rate of coronary events was 1.3% (95% CI, 0.7% to 2.5%) in women with no risk factors and 8.7% (CI, 7.1% to 10.8%) in women with five or more risk factors (a sixfold increase). At entry into HERS, 83% of participants were receiving aspirin or other antiplatelet agents, 33% were receiving beta-blockers, 18% were receiving angiotensin-converting enzyme inhibitors, and 53% were receiving lipid-lowering drugs. Women with more risk factors were less likely to be taking aspirin (P < 0.001) and lipid-lowering drugs (P = 0.006). CONCLUSIONS: Women with coronary disease are at high risk for myocardial infarction or death from coronary heart disease even in the absence of other risk factors, and their risk increases up to sixfold when many risk factors are present. Established drugs for secondary prevention, including aspirin, beta-blockers, and lipid-lowering agents, are underused in these women, especially those at highest risk.

Elevations of inflammatory and procoagulant biomarkers in elderly persons with renal insufficiency.

BACKGROUND: Renal insufficiency has been associated with cardiovascular disease events and mortality in several prospective studies, but the mechanisms for the elevated risk are not clear. Little is known about the association of renal insufficiency with inflammatory and procoagulant markers, which are potential mediators for the cardiovascular risk of kidney disease. METHODS AND RESULTS: The cross-sectional association of renal insufficiency with 8 inflammatory and procoagulant factors was evaluated using baseline data from the Cardiovascular Health Study, a population-based cohort study of 5888 subjects aged > or =65 years. C-reactive protein, fibrinogen, factor VIIc, and factor VIIIc levels were measured in nearly all participants; interleukin-6, intercellular adhesion molecule-1, plasmin-antiplasmin complex, and D-dimer levels were measured in nearly half of participants. Renal insufficiency was defined as a serum creatinine level > or =1.3 mg/dL in women and > or =1.5 mg/dL in men. Multivariate linear regression was used to compare adjusted mean levels of each biomarker in persons with and without renal insufficiency after adjustment for other baseline characteristics. Renal insufficiency was present in 647 (11%) of Cardiovascular Health Study participants. After adjustment for baseline differences, levels of C-reactive protein, fibrinogen, interleukin-6, factor VIIc, factor VIIIc, plasmin-antiplasmin complex, and D-dimer were significantly greater among persons with renal insufficiency (P<0.001). In participants with clinical, subclinical, and no cardiovascular disease at baseline, the positive associations of renal insufficiency with these inflammatory and procoagulant markers were similar. CONCLUSION: Renal insufficiency was independently associated with elevations in inflammatory and procoagulant biomarkers. These pathways may be important mediators leading to the increased cardiovascular risk of persons with kidney disease.
