Abstract
Non-valvular atrial fibrillation (NVAF) significantly contributes to the burden of stroke, particularly in elderly patients. The challenge of optimizing anticoagulation therapy is balancing efficacy and bleeding risk, especially as the same patients at high risk of stroke also tend to be at high risk of bleeding. Treating the elderly patient with NVAF presents special challenges because of their heightened risk for both stroke and bleeding. Despite clinical trial data and evidence-based guidelines, surveys indicate that physicians underuse anticoagulation in older patients for reasons that include overemphasis of bleeding risk, particularly with the increased risk of falling, at the cost of thromboembolic risk. Clinical trial data are now available, and real-world data are emerging, to illustrate the relative merits of the non-vitamin K antagonist oral anticoagulants compared with conventional anticoagulation in the treatment of elderly patients with this condition, and to suggest some subgroups of older patients who may be more suitable candidates for particular agents. Care of elderly patients with NVAF is often complicated by factors including risk of falling, adherence, health literacy, cognitive function, adverse effects, and involvement of caregivers, as well as other factors including the patient–provider relationship and logistical barriers to obtaining medication. Thus, conversations between clinicians and patients, as well as shared decision making, are important. In addition, elderly patients often suffer from comorbidities including hypertension, coronary heart disease, diabetes mellitus, COPD, and/or heart failure, which necessitate the use of multiple concomitant medications, increasing the risk of drug/drug interactions. This review provides an overview of clinical trial data on the use of non-vitamin K anticoagulant agents in elderly populations, and serves as a practical resource for the management of NVAF in the elderly patient.

Abstract
Background:
Despite proven efficacy and safety of statins for use in dyslipidemia patients, a significant proportion of patients report intolerance to statins leading to treatment discontinuation. In 2014, the National Lipid Association (NLA) Statin Intolerance (SI) Panel recognized a pressing need to better understand patient-centric experience of SI. We believe combining a clinical perspective with patient experience of SI provides a comprehensive view on management of SI.
Objective:
This abstract describes clinician’s perspective of SI and patients’ presentation of SI in clinical practice.
Methods:
Experts were identified based on publications in the CV and SI research area. Interviews were conducted with health care professionals with known expertise and practice experience in evaluating and treating patients with SI. Interviewers were trained to follow the open-ended, semi-structured guide. The experts summarized their professional background, defined and described characteristics of SI, and their current management of SI in clinical practice. Additionally, targeted probes by the interviewers obtained information pertinent to research questions not spontaneously reported by experts. Following the completion of coding, data were pooled and qualitatively analyzed for common themes.
Results:
Four physicians and one nurse practitioner participated in the interviews and reported that they had been treating patients for a range of 19-29 years. Each of the experts provided a unique definition of SI, and four (80.0%) reported that SI is different than experiencing side effects from statins. A total of 13 characteristics reflecting the patient experience with SI were identified from the expert perspective: muscle symptoms (muscle pain (n=5; 100%), muscle weakness (n=4; 80%), muscle cramps (n=1; 20%), fatigue (n=1; 20%)), CNS symptoms (forgetfulness (n=2; 40%), headache(n=1; 20%)), or GI symptoms (i.e.- (n=1; 20%), burping, constipation, diarrhea, gas, indigestion, reflux, or upset stomach ). Experts displayed common approaches to the management of SI patients, including changing the type of statin the patient was receiving, usually at a lower dose, and using alternative treatments either alone or in combination with a statin (n=5; 100%). Regardless of the strategies used for managing SI patients, four experts (80.0%) indicated that they encouraged their patients to continue using statins despite experiences of intolerance.
Conclusions:
This study reports the opinions of 5 experts with varying backgrounds concluding that SI is multi-faceted and primarily characterized in the context of muscle pain and weakness which is best assessed from the perspective of the patient. These results, in concert with results from a literature review and patient interviews, will inform a comprehensive and patient-centric understanding of SI and a measure to assess this phenomenon.

Abstract
Introduction:
The clinical and economic impact of statin intolerance (SI) in high CV risk patients is unknown due, in part, to a lack of consensus in its definition. We sought to define and validate an SI algorithm for use in an administrative database (AD) among high-CV risk patients
Methods:
Adults with ≥1 qualifying change (See Table 1) in statin therapy and ≥1 prior diagnosis of hyperlipidemia, hypercholesterolemia, or mixed dyslipidemia were identified from the AD of the Health Alliance Plan at Henry Ford Health System (HFHS). A sample of 1000 patients was drawn from the pool of eligible adults and stratified by high CV risk based on presence of comorbid conditions including diabetes, coronary heart disease, and peripheral artery disease. Statin utilization and adverse events data were abstracted both from the AD and the HFHS electronic medical record (EMR). SI was defined using both a primary definition inclusive of all possible statin related adverse events and a secondary definition that included only musculoskeletal events. SI was categorized as absolute (AI) or titration (TI) intolerance. The performance of the AD algorithm was assessed using measures of concordance (Cohen’s kappa [κ]) and accuracy (sensitivity, specificity, positive predictive value [PPV]) with the EMR as reference.
Results:
A total of 353 patients (48% female, 44% Caucasian, mean (SD) age 63 (12) years) were identified as high CV risk with 33% having a history of CHD, 77% diabetes and 2% PAD. Forty-two percent of patients were on simvastatin, 35% atorvastatin, 11% lovastatin, 7% rosuvastatin and 6% pravastatin/fluvastatin. Table 1 characterizes the validation sample. SI was identified in 19.3% and 20.7%, AI in 3.1% and 2.8%, and TI in 16.7% and 18.7% of patients in the EMR and AD, respectively. The algorithm identifying any SI had robust concordance (κ=0.73), good sensitivity (80.9%) and PPV (75.3%). The TI algorithm performed better (κ=0.78, sensitivity=86.4%, PPV=77.3%) than the AI algorithm (κ=0.56, sensitivity=54.5%, PPV=60.0%). Specificity was high (>94%) across all 3 algorithms.
Conclusion:
This study successfully defined SI among high-CV risk patients using an evidence-based validated algorithm. To our knowledge, this is the first such algorithm for use in AD to be made available to decision-makers.

Abstract
BACKGROUND AND AIMS While predictive tools are being developed to identify those at highest risk for developing diabetes, little is known whether these assays affect clinical care. METHODS AND RESULTS Thirty sites who used the PreDx(®) (Tethys BioScience, Emeryville, CA) abstracted clinical information from baseline clinic visits prior to a PreDx test and from the most recent visit at time of abstraction. All visits occurred between May 2008-April 2011 (median follow-up 198 days, IQR 124-334). The primary analysis was the influence of the PreDx test (5-year diabetes prediction) on subsequent care; descriptive statistics were used to summarize baseline and follow-up variables. Overall 913 patients with 2 abstracted visits were included. Relative to baseline, median SBP decreased 1.5 mmHg (p = 0.039), DBP decreased 2 mmHg (p < 0.001), LDL-C decreased 4 mg/dL (p = 0.009), and HDL-C increased 2 mg/dL (p < 0.001) at follow-up. Behavioral or lifestyle counseling was not significantly different from baseline to follow-up (71.2% vs. 68.1% (p = 0.077), but BMI was lower by 0.2 kg/m(2) at follow up (p = 0.013). At follow-up, more patients were prescribed metformin (13.7% vs. 9.7%, p < 0.001). A higher PreDx score was significantly associated with metformin prescription (p = 0.0003), lifestyle counseling (p = 0.0099), and a lower BMI at follow-up (p = 0.007). CONCLUSION The use of a prognostic test in patients perceived to be high risk for diabetes was associated with a modest but significant increase in the prescription of metformin and lifestyle interventions and a reduction in BMI.

Abstract
BACKGROUND Given that 4 million individuals in the United States have atrial fibrillation, understanding the epidemiology of this disease is crucial. We sought to identify and characterize the impact of age on national atrial fibrillation hospitalization patterns. METHODS The study sample was drawn from the 2009-2010 Nationwide Inpatient Sample. Patients hospitalized with a principal International Classification of Diseases, 9th Revision discharge diagnosis of atrial fibrillation were included. Patients were categorized as "older" (≥65 years) or "younger" (<65 years) for the purposes of analysis. The outcomes measured included hospitalization rate, length of stay, in-hospital mortality, and discharge status. RESULTS We identified 192,846 atrial fibrillation hospitalizations. There was significant geographic variation in hospitalizations for both younger and older age groups. States with high hospitalizations differed from those states known to have high stroke mortality. Younger patients (33% of the sample) were more likely to be obese (21% vs 8%, P < .001) and to use alcohol (8% vs 2%, P < .001). Older patients were more likely to have kidney disease (14% vs 7%, P < .001). Both age groups had high rates of hypertension and diabetes. Older patients had higher in-hospital mortality and were more likely to be discharged to a nursing or intermediate care facility. CONCLUSIONS Younger patients account for a substantial minority of atrial fibrillation hospitalizations in contemporary practice. Younger patients are healthier, with a different distribution of risk factors, than older patients who have higher associated morbidity and mortality.

Abstract
BACKGROUND Statin combination therapy and statin uptitration have been shown to be efficacious in low-density lipoprotein cholesterol (LDL-C) lowering and are recommended for patients with high-risk coronary heart disease (CHD) who do not reach guideline-endorsed LDL-C goals on statin monotherapy. OBJECTIVE This analysis evaluated treatment practice patterns and LDL-C lowering for patients with CHD/CHD risk equivalent on statin monotherapy in a real-world practice setting in the United States. METHODS In this retrospective, observational study, patients with CHD/CHD risk equivalent on statin therapy were identified during 2004 to 2008 in a US managed care database. Prescribing patterns and effect of switching from statin monotherapy to combination ezetimibe/simvastatin therapy vs uptitration to higher statin dose/potency level and no change from initial statin potency on LDL-C lowering were assessed. Percentage of change from baseline in LDL-C levels and odds ratios for LDL-C goal attainment were estimated with analyses of covariance and logistic regression. RESULTS Of 27,919 eligible patients on statin therapy, 2671 (9.6%) switched to ezetimibe/simvastatin therapy, 11,035 (39.5%) uptitrated statins, and 14,213 (50.9%) remained on the same statin monotherapy. LDL-C reduction from baseline and attainment of LDL-C <100 and <70 mg/dL were substantially greater for patients who switched to ezetimibe/simvastatin therapy (-24.0%, 81.2%, and 35.2%, respectively) than for patients who titrated (-9.6%, 68.0%, and 18.4%, respectively) or remained on initial statin therapy (4.9%, 72.2%, and 23.7%, respectively). The odds ratios for attainment of LDL-C <100 and <70 mg/dL were also higher for patients who switched than for patients who uptitrated and had no therapy change than for patients who titrated vs no therapy change. Similarly, among a subgroup of patients not at LDL-C <100 mg/dL on baseline therapy, attainment of LDL-C <100 and <70 mg/dL was greater for patients who switched than for statin uptitration vs no change, as well as for patients who uptritrated statins vs no therapy change. CONCLUSION In this study, LDL-C lowering and goal attainment rates improved substantially for patients with high-risk CHD on statin monotherapy who switched to combination ezetimibe/statin or uptitrated their statin therapies; however, approximately one-third of these patients still did not attain the optional recommended LDL-C goal of <70 mg/dL. Moreover, these higher efficacy lipid-lowering therapies were infrequently prescribed, indicating the need for further assessment of barriers to LDL-C goal attainment in actual practice settings.

Abstract
BACKGROUND The presence of a morning excess of ST-segment elevation myocardial infarction (STEMI) has been observed. The relation between patient characteristics and timing of STEMI may provide insight into the biological processes responsible for this phenomenon. HYPOTHESIS Patient baseline characteristics will vary with timing of STEMI. METHODS We performed an analysis using a large national registry of unselected patients with STEMI (N=45,218). Patients were categorized by time of symptom onset: early (6 am-2 pm), late day (2 pm-10 pm), and overnight (10 pm-6 am) then evaluated for variations in characteristics. RESULTS A circadian variation in the timing of symptom onset of STEMI was observed (early 41%, late day 32%, and overnight 26%, P<0.001). Circadian variations in factors known to alter timing of events were seen, including lower rates of home β-blocker use, smoking, and diabetes, with early onset of STEMI symptoms. In addition, patients in the 6 am to 2 pm subgroup were more likely older, white race, and male, with higher rates of home aspirin use and lower rates of obesity. Higher rates of coexisting cardiovascular disease, including prior heart failure, 3-vessel coronary artery disease, and depressed left ventricular ejection fraction, were observed in the overnight group. More robust antiplatelet therapy with home clopidogrel use was not associated with a change in the timing of events. CONCLUSIONS A morning excess of STEMI continues to exist and represents a potential target for preventative strategies. Patient baseline characteristics vary with the onset of STEMI and may reflect a physiologic relationship between these factors and the timing of events.

Abstract
The majority of chronic kidney disease patients die of cardiovascular disease prior to reaching end-stage renal disease. The combination of ezetimibe and a statin has been the focus of a number of recent studies, given initial data showing a substantial reduction in low- density lipoprotein with the addition of ezetimibe. However, it is unclear how this low-density lipoprotein reduction impacts cardiovascular disease outcomes. This review will briefly discuss the burden of cardiovascular disease and the pathophysiology of dyslipidemia in chronic kidney disease patients. It will then assess the data regarding the impact of adding ezetimibe to a statin on the general population, and specifically predialysis chronic kidney disease patients.

Abstract
OBJECTIVE This study evaluated the success in attaining non-HDL-cholesterol (non-HDL-C) goals in the multinational L-TAP 2 study. METHODS 9955 patients ≥20 years of age with dyslipidemia on stable lipid-lowering therapy were enrolled from nine countries. RESULTS Success rates for non-HDL-C goals were 86% in low, 70% in moderate, and 52% in high-risk patients (63% overall). In patients with triglycerides of >200 mg/dL success rates for non-HDL-C goals were 35% vs. 69% in those with ≤200 mg/dL (p < 0.0001). Among patients attaining their LDL-C goal, 18% did not attain their non-HDL-C goal. In those with coronary disease and at least two risk factors, only 34% and 30% attained respectively their non-HDL-C and LDL-C goals. Rates of failure in attaining both LDL-C and non-HDL-C goals were highest in Latin America. CONCLUSIONS Non-HDL-C goal attainment lagged behind LDL-C goal attainment; this gap was greatest in higher-risk patients.

Abstract
OBJECTIVES The aim of this study was to evaluate anticoagulant use patterns and bleeding risk in a contemporary population of patients with acute coronary syndrome. BACKGROUND Current practice guidelines support the use of unfractionated heparin, low molecular weight heparin, bivalirudin, or fondaparinux in non-ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI). Little is known about how these agents are selected in clinical practice. METHODS Between January 2007 and June 2009, data were captured for 72,699 patients with NSTEMI and 48,943 patients with STEMI at 360 U.S. hospitals for the NCDR ACTION Registry-GWTG (National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With the Guidelines). Patients were categorized based on anticoagulant strategy selected during hospitalization and their CRUSADE (Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of ACC/AHA [American College of Cardiology/American Heart Association] Guidelines) bleeding risk category. RESULTS At least 1 anticoagulant was administered to 66,279 patients (91.2%) with NSTEMI and 46,149 patients (94.3%) with STEMI. Among STEMI patients, unfractionated heparin was most commonly used (66%), followed by bivalirudin (14%) and low molecular weight heparin (8%). In NSTEMI patients, unfractionated heparin was also the most commonly used anticoagulant (42%), followed by low molecular weight heparin (27%) and then bivalirudin (13%). There were significant differences in anticoagulant use by age, risk factors, concomitant medications, and invasive care. There was a 5-fold difference in the rate of bleeding between patients in the lowest and highest CRUSADE bleeding risk groups, which was consistently observed in most anticoagulant groups. CONCLUSIONS There is a wide variability in the use of anticoagulant regimens with significant differences according to baseline characteristics and concomitant therapies. Major bleeding is common, though a great degree of the variability in the rate of bleeding is largely based on differences in baseline characteristics, comorbidities, and invasive treatment strategies, rather than specific anticoagulant regimens.

Abstract
Innate differences in gender physiology result in unique exposures, risk, and protection that are specific to women. Recognition and appreciation of these differences results in better treatment adaptations for women and better outcomes. Disparities between genders in the treatment of major cardiovascular risk factors still exist and are mostly secondary to underestimating or misunderstanding a woman's risk. Preventive therapies are less often recommended to women. Women are more likely to be diagnosed and treated for hypertension, but are less likely to reach treatment goals. High-risk women-including diabetic women-are less likely to be on lipid-lowering agents and reach a low-density lipoprotein level less than 100 mg/dL. Diabetic women are less likely to achieve a hemoglobin A(1c) level less than 7%. Through understanding these disparities, health care providers will be better able to screen female patients and institute evidence-based therapies for the prevention of cardiovascular disease.

Abstract
In the United States heart disease causes more than one-third of all deaths and most of these occur in women, not men, although women and health care professionals alike continue to view death from heart disease as a threat primarily to middle-aged men. The disparity between genders in the incidence of cardiovascular disease (CVD) may be the result of significant differences in both cardiovascular risk factors and presentation between men and women. This article reviews recent data regarding unique sex-specific characteristics of both risk for, and presentation of, CVD in women.

Abstract
BACKGROUND Despite the 2000 and 2007 redefinition of myocardial infarction (MI), patients who are troponin (Tn) positive ([+]) but MB negative ([-]) may not be considered to have MI, particularly in the absence of known coronary disease (prior MI or revascularization; coronary artery disease [CAD]). How this affects treatment and outcomes has not been well described. METHODS Direct arrival patients with non-ST elevation MI (NSTEMI) enrolled in the American College of Cardiology NCDR ACTION-GWTG Registry were included. Patients missing marker data who were Tn (-) and had CAD were excluded. Troponin (+) patients were categorized as MB (+) (n = 11,563) or MB (-) (n = 4,501). Treatments and in-hospital outcomes were compared between the 2 groups using logistic regression. RESULTS Of the 16,064 NSTEMI patients, 28% were MB (-). The MB (-) patients were older (median age 68 vs 65 years) and had more comorbidities (hypertension 71% vs 66%, diabetes 31% vs 27%, heart failure 22% vs 19%; all Ps < .01). After adjusting for baseline characteristics, MB (-) patients were significantly less likely to receive clopidogrel, antithrombins, glycoprotein IIb/IIIa antagonists, or angiography (all Ps < .001). In-hospital mortality was lower in MB (-) patients (3.8% vs 4.9%, P < .01), which remained significant after adjusting for baseline variables (odds ratio 0, 69, 95% CI 0.6-0.9, P = .002). CONCLUSIONS Patients without known CAD who have NSTEMI and are MB (-) have a higher risk profile but are less likely to receive guideline-recommended acute pharmacologic treatment than those who are MB (+). Given the relatively high mortality in this group, increased emphasis on improving quality of care in Tn (+)/MB (-) patients is warranted.

Abstract
BACKGROUND A previous study in 4703 patients suggested that a single-pill combination of amlodipine and atorvastatin is associated with greater adherence to therapy than a two-pill calcium channel antagonist (calcium channel blocker [CCB]) and HMG-CoA reductase inhibitor (statin) regimen. However, the impact of prior medication use on the potential adherence benefits of single-pill amlodipine/atorvastatin has not been studied. OBJECTIVE To compare adherence to single-pill amlodipine/atorvastatin versus two-pill CCB + statin regimens in a large managed care population, stratified according to prior CCB and statin use. METHODS This retrospective study was conducted among managed care enrolees in the US. Patients included in the analysis had to have a pharmacy claim for single-pill amlodipine/atorvastatin or claims for both a CCB and a statin within any 30-day window between April 2004 and April 2005. Adherence was measured over 6 months following the index date (the date of the first single-pill amlodipine/atorvastatin claim or of the claim for the second medication class for any two-pill CCB + statin regimen) as the proportion of days covered (PDC) by both CCB and statin therapy; patients were considered 'adherent' if PDC was > or =80%. Patients were divided into four cohorts based on pre-index CCB and statin use: (i) naive (CCB)/naive (statin); (ii) experienced (CCB)/naive (statin); (iii) naive (CCB)/experienced (statin); and (iv) experienced (CCB)/experienced (statin). Within each cohort, adherence was compared for patients receiving single-pill amlodipine/atorvastatin versus two-pill amlodipine + atorvastatin or other two-pill CCB + statin regimens (including amlodipine or atorvastatin but not both) at index. Multivariable logistic regression with propensity score weighting was used to adjust for covariates, including age, sex and co-morbidities. RESULTS In total, 35,430 patients were included in the analysis. At month 6 (after adjusting for covariates), patients in the experienced (CCB)/naive (statin) cohort receiving single-pill amlodipine/atorvastatin were more than twice as likely to be adherent as those receiving two-pill amlodipine + atorvastatin (odds ratio [OR] 2.20; p < 0.0001) or other two-pill CCB + statin regimens (OR 2.75; p < 0.0001). Similarly, patients in the naive (CCB)/experienced (statin) cohort receiving single-pill amlodipine/atorvastatin were more likely to be adherent than those receiving two-pill amlodipine + atorvastatin (OR 1.72; p < 0.0001) or other two-pill CCB + statin regimens (OR 2.81; p < 0.0001). In contrast, in the naive (CCB)/naive (statin) cohort there was no significant difference in adherence between patients receiving single-pill amlodipine/atorvastatin versus two-pill amlodipine + atorvastatin (OR 1.00), although patients receiving single-pill amlodipine/atorvastatin were slightly more likely to be adherent than those receiving other two-pill CCB + statin regimens (OR 1.29; p < 0.01). In the experienced (CCB)/experienced (statin) cohort there was also no significant difference between patients receiving single-pill amlodipine/atorvastatin versus two-pill amlodipine + atorvastatin (OR 1.08), and only a slightly greater likelihood of achieving adherence to single-pill amlodipine/atorvastatin versus other two-pill CCB + statin regimens (OR 1.19; p < 0.01). CONCLUSIONS This large retrospective study confirms previous observations that single-pill amlodipine/atorvastatin can help improve adherence versus two-pill CCB + statin regimens. However, greater improvements in adherence are likely to be observed in patients with prior experience of either CCB or statin therapy than in those either naive to, or experienced with, both therapies.

Abstract
Recent reports have described different risks of acute myocardial infarction (AMI) in association with specific oral antidiabetic medications. The present study compared the AMI incidence rates in new users of traditional neutral protamine Hagedorn (NPH) insulin and a long-acting synthetic insulin analog for basal insulin therapy. We retrospectively examined in-patient medical claims for AMI in a cohort of oral agent-treated patients with type 2 diabetes mellitus after the initiation of basal insulin therapy with either NPH (n = 5,461) or insulin glargine (n = 14,730) in a national administrative claims database comprising >30 managed healthcare plans in the United States. Poisson regression and Cox proportional hazards regression models, as well as the propensity score methods, were used to compare the subsequent AMI incidence rates after the initiation of NPH or glargine. At a mean follow-up of 2 years, the unadjusted AMI incidence was 17.6/1,000 person-years after the initiation of NPH versus 11.5/1,000 person-years after initiation of glargine (rate ratio 1.53, 95% confidence interval 1.29 to 1.81). The Cox regression model (hazard ratio 1.39, 95% confidence interval 1.14 to 1.69) and sensitivity analyses (hazard ratio range 1.30 to 1.56) showed a greater risk of AMI in the NPH group than in the glargine group. Propensity matched (1:1) analysis yielded similar results (odds ratio 1.55, 95% confidence interval 1.23 to 1.96 for NPH vs glargine). In conclusion, these results suggest that the initiation of basal insulin therapy with NPH rather than glargine in patients with type 2 diabetes mellitus is associated with a greater risk of AMI.

Abstract
OBJECTIVES To determine the priority that older adults with coexisting hypertension and fall risk give to optimizing cardiovascular outcomes versus fall- and medication symptom-related outcomes. DESIGN Interview. SETTING Community. PARTICIPANTS One hundred twenty-three cognitively intact persons aged 70 and older with hypertension and fall risk. MEASUREMENTS Discrete choice task was used to elicit the relative importance placed on reducing the risk of three outcomes: cardiovascular events, serious fall injuries, and medication symptoms. Risk estimates with and without antihypertensive medications were obtained from the literature. Participants chose between 11 pairs of options that displayed lower risks for one or two outcomes and a higher risk for the other outcome(s), versus the reverse. Results were used to calculate relative importance scores for the three outcomes. These scores, which sum to 100, reflect the relative priority participants placed on the difference between the risk estimates of each outcome. RESULTS Sixty-two participants (50.4%) placed greater importance on reducing risk of cardiovascular events than reducing risk of the combination of fall injuries and medication symptoms; 61 participants did the converse. A lower percentage of participants with chronic obstructive pulmonary disease (P=.02), unsteadiness (P=.02), functional dependency (P=.04), lower cognition (P=.02) and depressive symptoms (P=.03) prioritized cardiovascular outcomes over fall injuries and medication symptoms than did participants without these characteristics. CONCLUSION Interindividual variability in the face of competing outcomes supports individualizing decision-making to individual priorities. In the current example, this may mean forgoing antihypertensive medications or compromising on blood pressure reduction for some individuals.

Abstract
BACKGROUND Antihypertensive drugs are prescribed commonly in older adults for their beneficial cardiovascular and cerebrovascular effects, but few studies have assessed antihypertensive drugs' adverse effects on non-cardiovascular outcomes in routine clinical practice. OBJECTIVE To evaluate, among older adults, the association between antihypertensive medication use and physical performance, cognition, and mood. DESIGN AND SETTING Prospective cohort study in a Veterans Affairs primary care clinic, with patients enrolled in 2000-2001 and assessed for medication use, comorbidities, health behaviors, and other characteristics; and followed-up 1 year later. PARTICIPANTS 544 community-dwelling hypertensive men over age 65 years. MEASUREMENTS Timed chair stands; Trail Making Test part B; and Centers for Epidemiologic Studies Depression (CES-D) scores. RESULTS Participants had a mean age of 74.4 +/- 5.2 years and took a mean of 2.3 +/- 1.2 antihypertensive medications at baseline. After adjustment for age, comorbidities, level of blood pressure, and other confounders, each 1-unit increase in antihypertensive medication "intensity" was associated with a 0.11-second (95% confidence interval, 0.05-0.16) increase in the time required to complete the timed chair stands. No significant relationship was found between antihypertensive medication intensity and outcomes for Trail Making B or CES-D scores. CONCLUSIONS A higher cumulative exposure to antihypertensive medications in community-living older men was associated with adverse effects on physical performance, but not on the cognitive or depression measures available in this study. Clinicians should consider non-cardiovascular related adverse effects when treating older males taking multiple antihypertensive medications.

Abstract
OBJECTIVES To determine the relationship between hydroxymethyl glutaryl coenzyme A reductase inhibitor (statin) use and proximal muscle strength, cognition, and depression in older adults. DESIGN Observational cohort study. SETTING Outpatient primary care clinics. PARTICIPANTS Seven hundred fifty-six community-dwelling veterans aged 65 and older. MEASUREMENTS Timed chair stands (a measure of proximal muscle strength), Trail Making Test Part B (a measure of cognition), and the Center for Epidemiologic Studies Depression Scale score were measured at baseline and 1-year follow-up. Participants were assessed for statin prescriptions (and indications for or contraindications to their use), concomitant medication use, comorbidities, and other potential confounders. RESULTS Statin users (n=315) took a mean 6.6 medications, versus 4.6 for nonusers (n=441), and had a median duration of statin use of 727 days. Statin users were more likely to be white and had (as expected) more cardiac, cerebrovascular, and peripheral vascular disease. Based on multivariable models adjusting for pertinent covariates, statin users performed modestly better than nonusers for timed chair stands (-0.5 seconds; P=.04), Trail Making Test Part B (-7.7 seconds; P=.08), and depression scores (-0.2 points; P=.49) at follow-up. Of potentially high-risk participants (based on age, comorbidity, and number of medications), statin users also showed similar 1-year changes as nonusers, although worsened depression scores were found in those with greater comorbidity (+0.88 points; P=.10). CONCLUSION Older, community-dwelling male participants taking maintenance statin therapy had similar outcomes to those of nonusers in tests of muscle strength, cognition, and depression, but further examination of benefits and harms in different subgroups is warranted.

Abstract
BACKGROUND/OBJECTIVE Diet books dominate the New York Times Advice Best Seller list and consumers cite such books as an important source of nutrition information. However, the scientific support for nutrition claims presented as fact (nutrition facts) in diet books is not known. DESIGN/MEASUREMENTS We assessed the quality of nutrition facts in the best-selling South Beach Diet using support in peer-reviewed literature as a measure of quality. We performed structured literature searches on nutrition facts located in the books' text, and then assigned each fact to 1 of 4 categories (1) fact supported, (2) fact not supported, (3) fact both supported and not supported, and (4) no related papers. A panel of expert reviewers adjudicated the findings. RESULTS Forty-two nutrition facts were included. Fourteen (33%) facts were supported, 7 (17%) were not supported, 18 (43%) were both supported and not supported, and 3 (7%) had no related papers, including the fact that the diet had been "scientifically studied and proven effective." CONCLUSIONS Consumers obtain nutrition information from diet books. We found that over 67% of nutrition facts in a best-seller diet book may not be supported in the peer-reviewed literature. These findings have important implications for educating consumers about nutrition information sources.

Abstract
Control of hypertension is well established for the primary prevention of stroke. Prior studies, on the other hand, conflict over whether hypertension remains a risk factor for recurrent stroke and if blood pressure reduction is associated with better outcomes in this subset of patients. We review current evidence regarding the role of BP lowering for primary and secondary prevention of stroke. Current evidence amassed from both primary and secondary prevention trials demonstrate that BP reduction is a crucial common element in overall reduction of stroke risk.

Abstract
OBJECTIVES This study evaluated the impact of age on care and outcomes for non-ST-segment elevation acute coronary syndromes (NSTE ACS). BACKGROUND Recent clinical trials have expanded treatment options for NSTE ACS, now reflected in guidelines. Elderly patients are at highest risk, yet have previously been shown to receive less care than younger patients. METHODS In 56,963 patients with NSTE ACS at 443 U.S. hospitals participating in the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) National Quality Improvement Initiative from January 2001 to June 2003, we compared use of guidelines-recommended care across four age groups: <65, 65 to 74, 75 to 84, and > or =85 years. A multivariate model tested for age-related differences in treatments and outcomes after adjusting for patient, provider, and hospital factors. RESULTS Of the study population, 35% were > or =75 years old, and 11% were > or =85 years old. Use of acute anti-platelet and anti-thrombin therapy within the first 24 h decreased with age. Elderly patients were also less likely to undergo early catheterization or revascularization. Whereas use of many discharge medications was similar in young and old patients, clopidogrel and lipid-lowering therapy remained less commonly prescribed in elderly patients. In-hospital mortality and complication rates increased with advancing age, but those receiving more recommended therapies had lower mortality even after adjustment than those who did not. CONCLUSIONS Age impacts use of guidelines-recommended care for newer agents and early in-hospital care. Further improvements in outcomes for elderly patients by optimizing the safe and early use of therapies are likely.

Abstract
OBJECTIVE Thiazolidinediones (TZDs) and metformin are insulin-sensitizing antihyperglycemic agents with reported benefits on atherosclerosis. Despite extensive use in patients with diabetes and cardiovascular disease, there is a paucity of outcomes data with metformin and none yet with TZDs. We sought to determine the impact of these insulin sensitizers on outcomes in diabetic patients after hospitalization with acute myocardial infarction (AMI). RESEARCH DESIGN AND METHODS We conducted a retrospective cohort study of 24,953 Medicare beneficiaries with diabetes discharged after hospitalization with AMI between April 1998 and March 1999 or July 2000 and June 2001. The independent association between discharge prescription for metformin, TZD, or both agents and outcomes at 1 year was assessed in multivariable Cox proportional hazards models, adjusting for patient, physician, and hospital variables. The primary outcome was time to death within 1 year of discharge; secondary outcomes were time to first rehospitalization within 1 year of discharge for AMI, heart failure, and all causes. RESULTS There were 8,872 patients discharged on an antihyperglycemic agent, of which 819 were prescribed a TZD, 1,273 metformin, and 139 both drugs. After multivariable analysis, compared with patients prescribed an antihyperglycemic regimen that included no insulin sensitizer, mortality rates were not significantly different in patients treated with either metformin (hazard ratio [HR] 0.92 [95% CI 0.81-1.06]) or a TZD (0.92 [0.80-1.05]) but were lower in those prescribed both drugs (0.52 [0.34-0.82]). The results were similar among patients with heart failure. The prescription of a TZD was associated with a borderline higher risk of all-cause readmission (1.09[1.00-1.20]), predominately due to a higher risk for heart failure readmission (1.17 [1.05-1.30]). CONCLUSIONS Individually, prescription of insulin-sensitizing drugs is not associated with a significantly different risk of death in older diabetic patients within 1 year following AMI compared with other antihyperglycemic agents. Combined, however, metformin and TZDs may exert benefit. TZD prescription is associated with a higher risk of readmission for heart failure after myocardial infarction.

Abstract
Recurrent stroke is a major public health concern and new treatment strategies are needed. While modulation of the renin angiotensin aldosterone system (RAAS) has proven effective in reducing recurrent cardiac events, its role in preventing recurrent cerebrovascular events remains unclear. RAAS is both a circulating and tissue based hormonal system that regulates homeostasis and tissue responses to injury in both the CNS and the periphery, via the activity of angiotensin II (Ang II). Vascular and hematologic effects induced by Ang II including endothelial dysfunction, vascular structural changes, inflammation, hemostasis, and fibrinolysis are increasingly linked to the occurrence of cerebrovascular events. Animal models have shown that RAAS modulation may be protective in cerebrovascular disease. The HOPE and LIFE trials support the role of blood pressure independent mechanisms of RAAS modulation for improving outcomes in a broad range of patients with cardiovascular disease but do not specifically address recurrent stroke prevention. PROGRESS, a trial of secondary stroke prevention, demonstrates that blood pressure reduction with a combination strategy including the routine use of ACE inhibitors prevents recurrent stroke. Current evidence suggests that the RAAS plays an important role in the development and progression of cerebrovascular disease. Modulation of the RAAS holds promise for the secondary prevention of stroke, however, ongoing clinical trials will better define the exact role of ACE inhibitor and angiotensin II Type 1 receptor blocker therapy in stroke survivors.

Abstract
Over the past several years, results of clinical trials of lipid lowering have increased our understanding of the pathophysiology of coronary atherosclerosis and ischemia. Evidence is accumulating that cholesterol lowering has potential anti-ischemic effects and may have immediate consequences that have a favorable impact on coronary events, possibly even acute coronary syndromes. Yet, less than one half of all patients hospitalized for acute coronary syndromes have their cardiovascular risks appropriately modified. The results of recent statin trials provide impetus for the implementation of aggressive risk-reduction strategies in patients with coronary atherosclerosis, including those with recent acute coronary syndromes. Prevention is now a viable therapeutic goal.

Abstract
Although it is well established that cigarette smoking causes excess mortality, the extent of the increased risk has been challenged because self-selection biases and confounding factors may not have been adequately accounted for in prior studies. We therefore performed a propensity analysis on a population-based cohort. A logistic regression model was used to generate a propensity score for current smoking in 6,099 adults (mean age 46 years, 54% men, 36% current smokers) participating in the National Heart Lung and Blood Institute's (NHLBI) Lipid Research Clinic Prevalence Study. During 12 years of follow-up, 513 subjects (8%) died. After adjusting for age, current smoking was strongly associated with death (compared with never and former smokers, relative risk [RR] 2.69, 95% confidence interval [CI] 1.98 to 0.64, p <0.0001 and RR 1.79, 95% CI 1.26 to 2.55, p = 0.001, respectively). After adjusting for a propensity score based on 27 covariates and the covariates themselves, current smoking remained strongly and independently predictive of excessive death risk in smokers compared with never and former smokers (adjusted RR 2.96, 95% CI 2.16 to 4.05, p <0.0001 and adjusted RR 1.87, 95% CI 1.31 to 2.67, p = 0.0006, respectively). Although smokers were more likely to also drink alcohol, an interaction was noted, whereby, after adjustment for propensity score and other covariates, current smoking was associated with a moderately strong increase in mortality among drinkers (adjusted RR 2.00, 95% CI 1.42 to 2.82, p <0.0001), but was also associated with a markedly increased death risk among nondrinkers (adjusted RR 4.74, 95% CI 3.24 to 6.92, p <0.0001). The independent association of smoking with death even after a rigorous propensity analysis argues that it is highly unlikely that the link between smoking and mortality is materially biased or confounded.

Abstract
BACKGROUND Lipoprotein (a) has been associated with increased coronary artery disease (CAD) risk in men, but relatively little data exists in women. While age influences the cardiovascular risk associated with Lp(a) in men, little is known about this phenomenon in women. The impact of gender on Lp(a) has not been fully studied in an ongoing clinical practice. METHODS AND RESULTS Baseline Lp(a) values were measured in 918 CAD and 829 non-CAD patients (603 females, 1144 males) entering an outpatient prevention clinic. The age-specific association of elevated Lp(a) (> 30 mg/dl) with CAD was examined after adjustment for traditional risk factors. Lp(a) was a significant risk factor (OR = 1.9, CI, 1.4-2.6) in men and women (OR = 1.9, CI 1.3-2.9). In men age < or = 55 years the odds ratio for increased cardiovascular risk in high vs low Lp(a) was 2.5 (CI 1.6-3.9). In men < or = 55, CAD increased from 32 to 61% as Lp(a) progressively rose from < or = 5 to > or = 45 mg/dl (P value for trend < 0.001). No significant increase was observed in men > 55 years (OR = 1.3, CI 0.9-2.1). In women < or = 55 years, the risk of CAD increased from 22 to 35% (OR 1.6, CI 0.8-3.2), and increased from 38 to 63% in women > 55 (OR 2.1, CI 1.3-3.5). Further, of high-risk patients (men < or = 55 and women > 55 years) with an Lp(a) in the range of 20-44 mg/dl (third quartile), younger men showed a greater incidence of CAD (51%) than older women (43%). Both genders revealed substantial risk when the Lp(a) values were above 45 mg/dl. (OR = 3.7, CI = 2.0-6.8 in younger men; OR = 3.3, CI = 1.6-6.6 in older women). CONCLUSIONS In this cross sectional study of both men and women, elevated Lp(a) was associated with a significantly increased risk of CAD in men and women. While we corroborate previous reports on the lack of association in older men, the determination of an enhanced Lp(a)-related risk in older women was new and unanticipated. Further, in this population of high risk patients, substantial cardiovascular risk appeared to be represented by higher concentrations of Lp(a) in women than observed in men.

Abstract
BACKGROUND HDL cholesterol (HDL-C) is an important independent predictor of atherosclerosis, yet the role that HDL-C may play in the prediction of long-term survival after CABG remains unclear. The risk associated with a low HDL-C level in post-CABG men has not been delineated in relation to traditional surgical variables such as the use of arterial conduits, left ventricular function, and extent of disease. METHODS AND RESULTS We performed a prospective, observational study of 432 men who underwent CABG between 1978 and 1979 in whom preoperative HDL-C values were available. Baseline lipid and lipoprotein values, history of diabetes mellitus and hypertension, left ventricular ejection fraction, extent of disease, and use of internal thoracic arteries were recorded. Hazard ratios (HRs) were determined in the patients with and without a low HDL-C level, which was defined as the lowest HDL-C quartile (HDL-C </=35 mg/dL). After adjustment for age, as well as for baseline metabolic parameters and surgical variables just noted, HDL-C corresponded to both overall (HR 0.40, CI 0.20 to 0.83, P:=0.01) and event-free (HR 0.41, CI 0.24 to 0.70, P:=0.001) survival. Patients with a high HDL-C level (>35 mg/dL) were 50% more likely to survive at 15 years than were patients with low HDL-C level (</=35 mg/dL) (74% versus 57% adjusted survival, respectively; HR 1.72, P:=0.005). In addition, HDL-C showed a strong effect on time-to-event survival such that patients with an HDL-C level of >35 mg/dL were 50% more likely to survive without a subsequent myocardial infarction or revascularization (HR 1.42, P:=0.02). CONCLUSIONS HDL-C is an important predictor of survival in post-CABG patients. In this study of >8500 patient-years of follow-up, HDL-C was the most important metabolic predictor of post-CABG survival. One third fewer patients survive at 15 years if their HDL-C levels are </=35 mg/dL at the time of CABG. The measurement of HDL-C provides a compelling strategy for the identification of high-risk subsets of patients who undergo CABG.

Abstract
OBJECTIVES We sought to determine the efficacy and safety of platelet glycoprotein IIb/IIIa receptor (GP IIb/IIIa) blockade with abciximab in women undergoing percutaneous coronary intervention. BACKGROUND Although gender differences in response to platelet glycoprotein IIb/IIIa receptor blockade have been described, there have been no large clinical studies to assess these differences. METHODS Outcomes were determined using meta-analysis technique. RESULTS In the pooled analysis, the primary end point of death, myocardial infarction (MI) or urgent revascularization within 30 days was reduced from 11.3% to 5.8% (p<0.001) in men and from 12.7% to 6.5% (p<0.001) in women treated with abciximab. At six months, death, MI or urgent revascularization was reduced from 14.1% to 8.3% (p<0.001) in men and 16.0% to 9.9% (p<0.001) in women receiving abciximab. At one year, mortality was reduced from 2.7% to 1.9% (p = 0.06) in men and 4.0% to 2.5% (p = 0.03) in women treated with abciximab. Major bleeding events occurred in 2.9% versus 3.0% (p = 0.96) of women and 2.7% versus 1.3% (p = 0.003) of men treated with placebo versus abciximab, respectively. Minor bleeding events occurred in 4.7% versus 6.7% (p = 0.01) of women and 2.3% versus 2.2% (p = 0.94) of men treated with placebo versus abciximab, respectively. CONCLUSIONS This pooled analysis demonstrated no gender difference in protection from major adverse outcomes with GP IIb/IIIa inhibition with abciximab. Although women had higher rates of both major and minor bleeding events with abciximab compared with men, major bleeding in women was similar with and without abciximab. There was a small increased risk of minor bleeding with abciximab in women.

Abstract
BACKGROUND Clinical practice guidelines have been published for cardiac rehabilitation, directing programs to address secondary risk-reduction issues. The role of risk factor profiles in the referral of patients to cardiac rehabilitation programs has not been evaluated. METHODS Patients from the Cardiovascular Information Registry at the Cleveland Clinic Foundation (CCF) who entered the CCF hospital-based cardiac rehabilitation program (n = 371) were compared with those who did not participate in the CCF program (n = 2960) with respect to gender, demographics, and risk factor profile for CAD. A random subset of those who did not participate in the CCF program (n = 100) was interviewed by phone to determine participation patterns in other rehabilitation programs. RESULTS Only 11% of patients participated in CCF-based program. Standard risk factors were similar between participants and nonparticipants. Rehabilitation patients were younger (63 +/- 10 versus 66 +/- 10, P < 0.01) and as a group had better left ventricular function (moderate-severe left ventricle: 16% versus 23%, P < 0.01) than nonparticipants. Women were underrepresented in the CCF rehabilitation population (20% versus 30%, P < 0.01). Of the phone survey sample, 21% of patients entered other community-based rehabilitation programs. Similar trends with respect to risk factors, younger age, and better left ventricular function were noted for the community subset. However, women accounted for a greater percentage of the participants in the community programs than the CCF-based program (42.8% versus 19.7%, P < 0.03). CONCLUSIONS Conclusions based on institution-specific programs likely underestimate overall participation in cardiac rehabilitation. Traditional risk factors apparently are not considered when referring patients to cardiac rehabilitation programs. Younger patients with lower mortality risks preferentially participate in rehabilitation programs. Women are more likely to participate in community-based programs. Overall use of cardiac rehabilitation programs remains low.

Abstract
BACKGROUND Abnormal heart rate recovery after symptom-limited exercise predicts death. It is unknown whether this is also true among patients undergoing submaximal testing. OBJECTIVE To test the prognostic implications of heart rate recovery in cardiovascularly healthy adults undergoing submaximal exercise testing. DESIGN Population-based cohort study. SETTING 10 primary care sites. PARTICIPANTS 5234 adults without evidence of cardiovascular disease who were enrolled in the Lipid Research Clinics Prevalence Study. MEASUREMENTS Heart rate recovery was defined as the change from peak heart rate to that measured 2 minutes later (heart rate recovery was defined as < or =42 beats/min). RESULTS During 12 years of follow-up, 312 participants died. Abnormal heart rate recovery predicted death (relative risk, 2.58 [CI, 2.06 to 3.20]). After adjustment for standard risk factors, fitness, and resting and exercise heart rates, abnormal heart rate recovery remained predictive (adjusted relative risk, 1.55 [CI, 1.22 to 1.98]) (P<0.001). CONCLUSION Even after submaximal exercise, abnormal heart rate recovery predicts death.

Abstract
A biochemical link between homocysteine (tHcy) and lipoprotein(a) [Lp(a)] related to fibrin binding has been proposed. This hypothesis has not been specifically examined in human subjects. We sought to determine in a clinical setting whether these risk factors would interact to increase coronary artery disease (CAD) risk. We performed a cross-sectional analysis of 750 men and 403 women referred to a preventive cardiology clinic at the Cleveland Clinic Foundation, in whom baseline tHcy and Lp(a) data were available. Logistic regression after adjusting for standard cardiovascular risk factors was used to estimate the relative risk of CAD in patients with an Lp(a) >/=30 mg/dL and a tHcy >/=17 micromol/L. Neither isolated high tHcy (odds ratio [OR]=1.06, P=0.89) nor isolated high Lp(a) (OR=1.15, P=0.60) appeared to be associated with CAD in women. However, strong evidence of an association was seen when both risk factors were present (OR=4.83, P=0.003). Moreover, this increased risk showed evidence of an interactive effect beyond that attributable to either additive or multiplicative effects of tHcy and Lp(a) (P=0.03). In contrast, both elevated tHcy (OR=1.93, P=0. 05) and elevated Lp(a) (OR=1.87, P=0.01) showed evidence of being independent risk factors for CAD in men. The presence of both risk factors in men did not appear to confer additional risk (OR=2.00, P=0.09), even though ORs as high as 12.4 were observed within specific age intervals. Consistent with prior studies, tHcy and Lp(a) are risk factors, either independently or in concert, for CAD in this clinical population. More significantly, we found evidence that when both risk factors were present in women, the associated risk was greater than what would be expected if the 2 risks were simply acting independently. The absence of such an interactive effect in men may be due to the confounding effects of age manifested as "survivor bias." These clinical findings provide insights into the potential roles of both tHcy and Lp(a) in the pathogenesis of atherosclerosis.

Abstract
CONTEXT Thrombotic thrombocytopenic purpura (TTP) is a rare and often fatal disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, mental status changes, and renal dysfunction. Ticlopidine hydrochloride is 1 of several drugs that have been associated with this disorder and is currently used routinely in the approximately 500000 patients per year in the United States who undergo a percutaneous coronary intervention involving a stent. OBJECTIVES To determine the incidence and describe the clinical course of TTP due to ticlopidine therapy following stenting. DESIGN Retrospective analysis of cohort of all patients undergoing coronary stenting at the Evaluation of Platelet IIb/IIIa Inhibitor for Stenting (EPISTENT) study sites. SETTING Sixty-three centers throughout the United States and Canada. PATIENTS A total of 43322 patients who underwent a percutaneous coronary intervention and received a coronary stent during a 1-year period from 1996 to 1997. MAIN OUTCOME MEASURES Cases of TTP following stenting during the 1-year period to determine the incidence of TTP due to ticlopidine therapy following coronary stenting. Additional cases were collected from these and other centers across North America to further describe the clinical presentation and course of TTP due to ticlopidine therapy following stenting. RESULTS Nine cases of TTP following stenting were recognized at the 63 centers during the specified period, giving an incidence of 1 case per 4814 patients treated (0.02%; 95% confidence interval, 1 case per 2533 to 1 case per 10 541 patients treated). Ten additional cases of TTP related to ticlopidine therapy following stenting were identified from other centers, were identified from the primary centers outside the pre-defined period, or involved a noncoronary stent. Four patients (21%) received ticlopidine for 2 weeks or fewer, 14 patients (74%) for 2 to 4 weeks, and 1 patient (5%) for 8 weeks. The mean time of ticlopidine treatment prior to TTP diagnosis was 22 days (range, 5-60 days). The overall mortality rate was 21% (4/19), with all 4 deaths occurring in patients not treated with plasmapheresis, whereas there were no deaths among the 13 patients who received plasmapheresis. CONCLUSION The findings of a TTP incidence of 0.02% in our cohort of ticlopidine-treated patients following coronary stenting suggests that TTP occurs much more commonly in this population than the estimated incidence of 0.0004% in the general population. The mortality rate for this rare complication exceeds 20%. Limiting ticlopidine therapy to 2 weeks after stenting does not prevent the development of TTP. Rapid diagnosis and treatment that includes plasmapheresis are critical for improved survival.
