Background— Mineralocorticoid receptor antagonists improve outcomes in patients with systolic heart failure but may induce worsening of renal function (WRF) and hyperkalemia (HK). We assessed the risk factors for mineralocorticoid receptor antagonist–related WRF and for HK, as well as the association between HK and WRF with clinical outcomes in the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF). Methods and Results— Serial changes in estimated glomerular filtration rate and in serum potassium were available in 2737 patients during a median 21-month follow-up. HK variably defined as serum K >4.5, 5, or 5.5 mmol/L occurred in 74.7%, 32.5%, and 8.9% patients enrolled in EMPHASIS-HF, respectively. WRF defined as a decrease in estimated glomerular filtration rate >20% or >30% from baseline occurred in 27% and 14% of patients, respectively. Patients assigned eplerenone displayed modest and early but significant and persistent (1) rise in serum potassium and (2) reduction in estimated glomerular filtration rate when compared with those assigned placebo. In multivariate analyses, eplerenone was associated with a higher incidence of WRF and HK, which were interrelated and also associated with baseline patient characteristics (eg, age ≥75 years, hypertension, diabetes mellitus, nonwhite race, ejection fraction <30%, and treatment with an antiarrythmics drug or loop diuretic). Eplerenone retained its survival benefits without any significant interaction with the association between HK >5.5 mmol/L only and WRF and worse outcomes. Conclusions— In patients with heart failure receiving optimal therapy, WRF and HK were more frequent when eplerenone was added, but their occurrence did not eliminate the survival benefit of eplerenone.

1) GH-deficient patients properly treated in childhood can have normal BMD, body composition, cardiac function, muscle strength, carbohydrate and lipid metabolism, and QOL when reaching adult height; and 2) continuation of GH therapy for 2 yr did not change these measures as compared to placebo-treated or control subjects. GH-deficient adolescents in good metabolic status at the time of epiphyseal fusion may safely discontinue GH for at least 2 yr. Follow-up is needed to determine whether GH therapy is eventually warranted in subjects treated with GH during childhood.

on behalf of the SPARCL InvestigatorsBackground and Purpose-Laboratory experiments suggest statins reduce stroke severity and improve outcomes. The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial was a placebo-controlled, randomized trial designed to determine whether treatment with atorvastatin reduces strokes in subjects with recent stroke or transient ischemic attack (nϭ4731). We analyzed SPARCL trial data to determine whether treatment favorably shifts the distribution of severities of ischemic cerebrovascular outcomes. Methods-Severity was assessed with the National Institutes of Health Stroke Scale, Barthel Index, and modified Rankin Scale score at enrollment (1 to 6 months after the index event) and 90 days poststroke in subjects having a stroke during the trial. Results-Over 4.9 years, strokes occurred in 576 subjects. There were reductions in fatal, severe (modified Rankin Scale score 5 or 4), moderate (modified Rankin Scale score 3 or 2), and mild (modified Rankin Scale score 1 or 0) outcome ischemic strokes and transient ischemic attacks and an increase in the proportion of event-free subjects randomized to atorvastatin (PϽ0.001 unadjusted and adjusted). Results were similar for all outcome events (ischemic and hemorrhagic, PϽ0.001 unadjusted and adjusted) with no effect on outcome hemorrhagic stroke severity (Pϭ0.174 unadjusted, Pϭ0.218 adjusted). If the analysis is restricted to those having an outcome ischemic stroke (ie, excluding those having a transient ischemic attack or no event), there was only a trend toward lesser severity with treatment based on the modified Rankin Scale score (Pϭ0.0647) with no difference based on the National Institutes of Health Stroke Scale or Barthel Index. Conclusion-The

Background-Information about physicians' adherence to cholesterol management guidelines remains scant. The present survey updates our knowledge of lipid management worldwide. Methods and Results-Lipid levels were determined at enrollment in dyslipidemic adult patients on stable lipid-lowering therapy in 9 countries. The primary end point was the success rate, defined as the proportion of patients achieving appropriate low-density lipoprotein cholesterol (LDL-C) goals for their given risk. The mean age of the 9955 evaluable patients was 62Ϯ12 years; 54% were male. Coronary disease and diabetes mellitus had been diagnosed in 30% and 31%, respectively, and 14% were current smokers. Current treatment consisted of a statin in 75%. The proportion of patients achieving LDL-C goals according to relevant national guidelines ranged from 47% to 84% across countries. In low-, moderate-, and high-risk groups, mean LDL-C was 119, 109, and 91 mg/dL and mean high-density lipoprotein cholesterol was 62, 49, and 50 mg/dL, respectively. The success rate for LDL-C goal achievement was 86% in low-, 74% in moderate-, and 67% in high-risk patients (73% overall). However, among coronary heart disease patients with Ն2 risk factors, only 30% attained the optional LDL-C goal of Ͻ70 mg/dL. In the entire cohort, high-density lipoprotein cholesterol was Ͻ40 mg/dL in 19%, 40 to 60 mg/dL in 55%, and Ͼ60 mg/dL in 26% of patients. Conclusions-Although there is room for improvement, particularly in very-high-risk patients, these results indicate that lipid-lowering therapy is being applied much more successfully than it was a decade ago.

on Behalf of the SPARCL InvestigatorsBackground and Purpose-The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial found that treatment with atorvastatin 80 mg per day reduced the risk of stroke and cardiovascular events in patients with a recent transient ischemic attack (TIA) or stroke. We hypothesized this benefit would be greatest in the subgroup of patients with carotid stenosis. Methods-The SPARCL trial randomized patients with TIA or stroke within 1 to 6 months without known coronary heart disease (CHD) and low-density lipoprotein cholesterol 100 to 190 mg/dL to treatment with atorvastatin 80 mg per day or placebo. Investigators identified subjects as having carotid stenosis not requiring revascularization at the time of randomization. Of the total SPARCL population, 1007 were documented as having carotid stenosis at baseline, 3271 did not, and the status of 453 was unknown. Results-We found no heterogeneity in the treatment effect for the SPARCL primary (fatal and nonfatal stroke) and secondary end points between the group with and without carotid stenosis. The group with carotid artery stenosis had greater benefit when all cerebro-and cardiovascular events were combined. In the group with carotid artery stenosis, treatment with atorvastatin was associated with a 33% reduction in the risk of any stroke (hazard ratio [HR]

Objective To assess the efficacy and safety of varenicline (a licensed cigarette smoking cessation aid) in helping users of smokeless tobacco to quit. Design Double blind, placebo controlled, parallel group, multicentre, randomised controlled trial. Setting Medical clinics (mostly primary care) in Norway and Sweden. Participants Men and women aged ≥18 who used smokeless tobacco at least eight times a day, with no abstinence period over three months within one year before screening, who wanted to quit all tobacco use. Participants were excluded if they used any other form of tobacco (except smokeless tobacco) or medication to stop smoking within three months of screening or had any pre-existing medical or psychiatric condition. Interventions Varenicline 1 mg twice daily (titrated during the first week) or placebo for 12 weeks, with 14 weeks' follow-up after treatment. Main outcome measures The primary end point was the four week continuous abstinence rate at the end of treatment (weeks 9-12) confirmed with cotinine concentration. A secondary end point was continuous abstinence rate for weeks 9-26. Safety and tolerability were also evaluated. Results 431 participants (213 varenicline; 218 placebo) were randomised and received at least one dose of study drug. Participants' demographics and baseline use of smokeless tobacco were similar (89% (189) and 90% (196), respectively, were men; mean age in both groups was 43.9; participants used smokeless tobacco products about 15 times a day, and about 80% first used smokeless tobacco within 30 minutes after awakening). Continuous abstinence rate at week 9-12 was higher in the varenicline group than the placebo group (59% (125) v 39% (85); relative risk 1.60, 95% confidence interval 1.32 to 1.87, P<0.001; risk difference 20%; number needed to treat 5). The advantage of varenicline over placebo persisted through 14 weeks of follow-up (continuous abstinence rate at week 9-26 was 45% (95) v 34% (73); relative risk 1
