Abstract
BACKGROUND Cardiogenic shock (CS) and low cardiac output syndrome (LCOS) are potentially life-threatening complications of acute myocardial infarction (AMI), heart failure (HF) or cardiac surgery. While there is solid evidence for the treatment of other cardiovascular diseases of acute onset, treatment strategies in haemodynamic instability due to CS and LCOS remains less robustly supported by the given scientific literature. Therefore, we have analysed the current body of evidence for the treatment of CS or LCOS with inotropic and/or vasodilating agents. This is the second update of a Cochrane review originally published in 2014. OBJECTIVES Assessment of efficacy and safety of cardiac care with positive inotropic agents and vasodilator agents in CS or LCOS due to AMI, HF or after cardiac surgery. SEARCH METHODS We conducted a search in CENTRAL, MEDLINE, Embase and CPCI-S Web of Science in October 2019. We also searched four registers of ongoing trials and scanned reference lists and contacted experts in the field to obtain further information. No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials (RCTs) enrolling patients with AMI, HF or cardiac surgery complicated by CS or LCOS. DATA COLLECTION AND ANALYSIS We used standard methodological procedures according to Cochrane standards. MAIN RESULTS We identified 19 eligible studies including 2385 individuals (mean or median age range 56 to 73 years) and three ongoing studies. We categorised studies into 11 comparisons, all against standard cardiac care and additional other drugs or placebo. These comparisons investigated the efficacy of levosimendan versus dobutamine, enoximone or placebo; enoximone versus dobutamine, piroximone or epinephrine-nitroglycerine; epinephrine versus norepinephrine or norepinephrine-dobutamine; dopexamine versus dopamine; milrinone versus dobutamine and dopamine-milrinone versus dopamine-dobutamine. All trials were published in peer-reviewed journals, and analyses were done by the intention-to-treat (ITT) principle. Eighteen of 19 trials were small with only a few included participants. An acknowledgement of funding by the pharmaceutical industry or missing conflict of interest statements occurred in nine of 19 trials. In general, confidence in the results of analysed studies was reduced due to relevant study limitations (risk of bias), imprecision or indirectness. Domains of concern, which showed a high risk in more than 50% of included studies, encompassed performance bias (blinding of participants and personnel) and bias affecting the quality of evidence on adverse events. All comparisons revealed uncertainty on the effect of inotropic/vasodilating drugs on all-cause mortality with a low to very low quality of evidence. In detail, the findings were: levosimendan versus dobutamine (short-term mortality: RR 0.60, 95% CI 0.36 to 1.03; participants = 1701; low-quality evidence; long-term mortality: RR 0.84, 95% CI 0.63 to 1.13; participants = 1591; low-quality evidence); levosimendan versus placebo (short-term mortality: no data available; long-term mortality: RR 0.55, 95% CI 0.16 to 1.90; participants = 55; very low-quality evidence); levosimendan versus enoximone (short-term mortality: RR 0.50, 0.22 to 1.14; participants = 32; very low-quality evidence; long-term mortality: no data available); epinephrine versus norepinephrine-dobutamine (short-term mortality: RR 1.25; 95% CI 0.41 to 3.77; participants = 30; very low-quality evidence; long-term mortality: no data available); dopexamine versus dopamine (short-term mortality: no deaths in either intervention arm; participants = 70; very low-quality evidence; long-term mortality: no data available); enoximone versus dobutamine (short-term mortality RR 0.21; 95% CI 0.01 to 4.11; participants = 27; very low-quality evidence; long-term mortality: no data available); epinephrine versus norepinephrine (short-term mortality: RR 1.81, 0.89 to 3.68; participants = 57; very low-quality evidence; long-term mortality: no data available); and dopamine-milrinone versus dopamine-dobutamine (short-term mortality: RR 1.0, 95% CI 0.34 to 2.93; participants = 20; very low-quality evidence; long-term mortality: no data available). No information regarding all-cause mortality were available for the comparisons milrinone versus dobutamine, enoximone versus piroximone and enoximone versus epinephrine-nitroglycerine. AUTHORS' CONCLUSIONS At present, there are no convincing data supporting any specific inotropic or vasodilating therapy to reduce mortality in haemodynamically unstable patients with CS or LCOS. Considering the limited evidence derived from the present data due to a high risk of bias and imprecision, it should be emphasised that there is an unmet need for large-scale, well-designed randomised trials on this topic to close the gap between daily practice in critical care of cardiovascular patients and the available evidence. In light of the uncertainties in the field, partially due to the underlying methodological flaws in existing studies, future RCTs should be carefully designed to potentially overcome given limitations and ultimately define the role of inotropic agents and vasodilator strategies in CS and LCOS.

Abstract
BACKGROUND Cardiogenic shock (CS) and low cardiac output syndrome (LCOS) as complications of acute myocardial infarction (AMI), heart failure (HF) or cardiac surgery are life-threatening conditions. While there is a broad body of evidence for the treatment of people with acute coronary syndrome under stable haemodynamic conditions, the treatment strategies for people who become haemodynamically unstable or develop CS remain less clear. We have therefore summarised here the evidence on the treatment of people with CS or LCOS with different inotropic agents and vasodilative drugs. This is the first update of a Cochrane review originally published in 2014. OBJECTIVES To assess efficacy and safety of cardiac care with positive inotropic agents and vasodilator strategies in people with CS or LCOS due to AMI, HF or cardiac surgery. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and CPCI-S Web of Science in June 2017. We also searched four registers of ongoing trials and scanned reference lists and contacted experts in the field to obtain further information. No language restrictions were applied. SELECTION CRITERIA Randomised controlled trials in people with myocardial infarction, heart failure or cardiac surgery complicated by cardiogenic shock or LCOS. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We identified 13 eligible studies with 2001 participants (mean or median age range 58 to 73 years) and two ongoing studies. We categorised studies into eight comparisons, all against cardiac care and additional other active drugs or placebo. These comparisons investigated the efficacy of levosimendan versus dobutamine, enoximone or placebo, epinephrine versus norepinephrine-dobutamine, amrinone versus dobutamine, dopexamine versus dopamine, enoximone versus dopamine and nitric oxide versus placebo.All trials were published in peer-reviewed journals, and analysis was done by the intention-to-treat (ITT) principle. Twelve of 13 trials were small with few included participants. Acknowledgement of funding by the pharmaceutical industry or missing conflict of interest statements emerged in five of 13 trials. In general, confidence in the results of analysed studies was reduced due to serious study limitations, very serious imprecision or indirectness. Domains of concern, which show a high risk of more than 50%, include performance bias (blinding of participants and personnel) and bias affecting the quality of evidence on adverse events.Levosimendan may reduce short-term mortality compared to a therapy with dobutamine (RR 0.60, 95% CI 0.37 to 0.95; 6 studies; 1776 participants; low-quality evidence; NNT: 16 (patients with moderate risk), NNT: 5 (patients with CS)). This initial short-term survival benefit with levosimendan vs. dobutamine is not confirmed on long-term follow up. There is uncertainty (due to lack of statistical power) as to the effect of levosimendan compared to therapy with placebo (RR 0.48, 95% CI 0.12 to 1.94; 2 studies; 55 participants, very low-quality evidence) or enoximone (RR 0.50, 95% CI 0.22 to 1.14; 1 study; 32 participants, very low-quality evidence).All comparisons comparing other positive inotropic, inodilative or vasodilative drugs presented uncertainty on their effect on short-term mortality with very low-quality evidence and based on only one RCT. These single studies compared epinephrine with norepinephrine-dobutamine (RR 1.25, 95% CI 0.41 to 3.77; 30 participants), amrinone with dobutamine (RR 0.33, 95% CI 0.04 to 2.85; 30 participants), dopexamine with dopamine (no in-hospital deaths from 70 participants), enoximone with dobutamine (two deaths from 40 participants) and nitric oxide with placebo (one death from three participants). AUTHORS' CONCLUSIONS Apart from low quality of evidence data suggesting a short-term mortality benefit of levosimendan compared with dobutamine, at present there are no robust and convincing data to support a distinct inotropic or vasodilator drug-based therapy as a superior solution to reduce mortality in haemodynamically unstable people with cardiogenic shock or LCOS.Considering the limited evidence derived from the present data due to a generally high risk of bias and imprecision, it should be emphasised that there remains a great need for large, well-designed randomised trials on this topic to close the gap between daily practice in critical care medicine and the available evidence. It seems to be useful to apply the concept of 'early goal-directed therapy' in cardiogenic shock and LCOS with early haemodynamic stabilisation within predefined timelines. Future clinical trials should therefore investigate whether such a therapeutic concept would influence survival rates much more than looking for the 'best' drug for haemodynamic support.

Abstract
BACKGROUND Low cardiac output syndrome remains a serious complication, and accounts for substantial morbidity and mortality in the postoperative course of paediatric patients undergoing surgery for congenital heart disease. Standard prophylactic and therapeutic strategies for low cardiac output syndrome are based mainly on catecholamines, which are effective drugs, but have considerable side effects. Levosimendan, a calcium sensitiser, enhances the myocardial function by generating more energy-efficient myocardial contractility than achieved via adrenergic stimulation with catecholamines. Thus potentially, levosimendan is a beneficial alternative to standard medication for the prevention of low cardiac output syndrome in paediatric patients after open heart surgery. OBJECTIVES To review the efficacy and safety of the postoperative prophylactic use of levosimendan for the prevention of low cardiac output syndrome and mortality in paediatric patients undergoing surgery for congenital heart disease. SEARCH METHODS We identified trials via systematic searches of CENTRAL, MEDLINE, Embase, and Web of Science, as well as clinical trial registries, in June 2016. Reference lists from primary studies and review articles were checked for additional references. SELECTION CRITERIA We only included randomised controlled trials (RCT) in our analysis that compared prophylactic levosimendan with standard medication or placebo, in infants and children up to 18 years of age, who were undergoing surgery for congenital heart disease. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias according to a pre-defined protocol. We obtained additional information from all but one of the study authors of the included studies. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of evidence from the studies that contributed data to the meta-analyses for the prespecified outcomes. We created a 'Summary of findings' table to summarise the results and the quality of evidence for each outcome. MAIN RESULTS We included five randomised controlled trials with a total of 212 participants in the analyses. All included participants were under five years of age. Using GRADE, we assessed there was low-quality evidence for all analysed outcomes. We assessed high risk of performance and detection bias for two studies due to their unblinded setting. Levosimendan showed no clear effect on risk of mortality (risk ratio (RR) 0.47, 95% confidence interval (CI) 0.12 to 1.82; participants = 123; studies = 3) and no clear effect on low cardiac output syndrome (RR 0.64, 95% CI 0.39 to 1.04; participants = 83; studies = 2) compared to standard treatments. Data on time-to-death were not available from any of the included studies.There was no conclusive evidence on the effect of levosimendan on the secondary outcomes. The length of intensive care unit stays (mean difference (MD) 0.33 days, 95% CI -1.16 to 1.82; participants = 188; studies = 4), length of hospital stays (MD 0.26 days, 95% CI -3.50 to 4.03; participants = 75; studies = 2), duration of mechanical ventilation (MD -0.04 days, 95% CI -0.08 to 0.00; participants = 208; studies = 5), and the risk of mechanical circulatory support or cardiac transplantation (RR 1.49, 95% CI 0.19 to 11.37; participants = 60; studies = 2) did not clearly differ between the groups. Published data about adverse effects of levosimendan were limited. A meta-analysis of hypotension, one of the most feared side effects of levosimendan, was not feasible because of the heterogeneous expression of blood pressure values. AUTHORS' CONCLUSIONS The current level of evidence is insufficient to judge whether prophylactic levosimendan prevents low cardiac output syndrome and mortality in paediatric patients undergoing surgery for congenital heart disease. So far, no significant differences have been detected between levosimendan and standard inotrope treatments in this setting.The authors evaluated the quality of evidence as low, using the GRADE approach. Reasons for downgrading were serious risk of bias (performance and detection bias due to unblinded setting of two RCTs), serious risk of inconsistency, and serious to very serious risk of imprecision (small number of included patients, low event rates).

Abstract
Plasma B-type natriuretic peptide (BNP) levels were obtained from 146 patients with unstable angina pectoris, non—ST-segment elevation myocardial infarction (MI), or ST-segment elevation MI to determine their value in predicting the presence of new heart failure, recurrent MI or ischemia, or death 1 month after the index event. Patients with elevated plasma BNP levels (>80 pg/mL) had a significantly higher incidence of new heart failure and all-cause mortality than those with a normal plasma BNP level (≤80 pg/mL). Early revascularization with percutaneous intervention or coronary artery bypass grafting significantly reduced the incidence of new heart failure and all-cause mortality in patients with an elevated plasma BNP level, but had no effect on individual outcomes in the normal plasma BNP subgroup.

Abstract
The Northern New England Cardiovascular Disease Study Group (NNECDSG) was formed as a regional clinical database that would allow clinicians to track outcomes after cardiac interventions. The purpose of the NNECDSG would be to use its database and organizational structure to seek best practices and disseminate information aimed at improving results for patients undergoing cardiovascular interventions. Since 1987, this voluntary regional collaborative of clinicians, hospital administrators, and health care research personnel has tracked consecutive cardiovascular interventions performed throughout Northern New England and reported its findings to the clinicians. Collaboration between NNECDSG institutions has led to progressive refinements in the clinical database, institutional site visits, efforts to understand and standardize ideal processes of care, risk-stratification tools to aid in decision making, and most recently, tools to track and report on appropriateness of interventions based on national criteria. As a result of these efforts, mortality rates after coronary bypass graft surgery have steadily declined and the variation in mortality rates between institutions has disappeared.

Abstract
Although the landscape of heart failure continues to rapidly evolve, and the widespread use of evidence-based pharmaceutical and device therapies has improved overall survival rates, mortality rates in heart failure patients remain high. Understanding the mode of death in heart failure is particularly important if we are to improve survival. This study reviews the evaluation of modes of death from heart failure and discusses the therapies, both pharmaceutical and device, that are useful in preventing these sequelae.

Abstract
Significant morbidity and mortality is associated with tricuspid valve replacement, and controversy still exists as to the ideal prosthesis in this position. This study aimed to identify the risk factors for low cardiac output and mortality, and whether bioprosthetic or mechanical valves perform better in the tricuspid position. Results of 121 tricuspid valve replacements in 104 patients between January 1966 and December 2002 were reviewed. Most patients were in New York Heart Association functional class III or IV. Perioperative mortality was 19%. On multivariate analysis, age and preoperative jaundice were significant predictors of low cardiac output; age, jaundice, atrial fibrillation, and bypass time were significant predictors of mortality. Mechanical valves were significantly more prone to thromboembolism, whereas bioprostheses suffered structural valve deterioration. There were no significant differences in anticoagulation or bleeding episodes between the two groups, nor in valve-related events, deaths, and long term survival. There was no significant difference in performance so as to recommend one type over the other, but bioprosthetic valves may be more favorable as they fail predictably.

Abstract
OBJECTIVES This study examined the trends in the relative contributions of cardiovascular and noncardiovascular mortality to total mortality according to use of beta-blockers in clinical trials of patients with heart failure with reduced ejection fraction (HF-REF). BACKGROUND With the increasingly widespread use of disease-modifying therapies, particularly beta-blockers, in HF-REF, the proportion of patients dying from cardiovascular causes is likely to be decreasing. METHODS In a systematic review, 2 investigators independently searched online databases to identify clinical trials including >400 patients with chronic heart failure published between 1986 and 2014 and that adjudicated cause of death. Trials were divided into 3 groups on the basis of the proportion of patients treated with a beta-blocker (<33% [low], 33% to 66% [medium], and >66% [high]). Percentages of total deaths adjudicated as cardiovascular or noncardiovascular were calculated by weighted means and weighted standard deviations. Weighted Student t tests were used to compare results between groups. RESULTS Sixty-six trials met the inclusion criteria with a total of 136,182 patients and 32,140 deaths. There was a sequential increase in the percentage of noncardiovascular deaths with increasing beta-blocker use from 11.4% of all deaths in trials with low beta-blocker use to 19.1% in those with high beta-blocker use (p < 0.001). CONCLUSIONS In trials of patients with HF-REF, the proportion of deaths adjudicated as cardiovascular has decreased. Cardiovascular mortality, and not all-cause mortality, should be used as an endpoint for trials of new treatments for HF-REF.

Abstract
BACKGROUND To determine the clinical risk factors predictive of the 5-year mortality in patients with low cardiac output syndrome (LCOS) after cardiac surgery. In addition, to assess the influence of inflammation and myocardial dysfunction severity, as measured by C-reactive protein (CRP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations, on outcome. METHODS We studied 30 patients who underwent cardiac surgery and developed postoperative LCOS requiring inotropic support for longer than 48 hours after intensive care unit (ICU) admission. All patients received a 24-hour infusion of levosimendan after study enrolment. We measured the following at baseline, 24 h, 48 h and 7 days: clinical data, serum NT-proBNP and serum CRP levels. Patients were followed-up at 5 years for death by any cause. A risk-adjusted Cox proportional hazards regression model was used for statistical analysis. Hazard ratios and their 95% confidence intervals (CI) are presented. RESULTS The 5-year mortality was 36.6% (n.=11). The predictors of 5-year mortality were the presence of dilated cardiomyopathy (HR=36.909; 95% CI: 1.901-716.747; P=0.017), a higher central venous pressure (CVP) at 48 hours (HR=2.686; 95% CI: 1.383-5.214; P=0.004), and lower CRP levels on day 7 (HR=0.963; 95% CI: 0.933-0.994; P=0.021). NT-proBNP levels showed a trend to higher initial levels in survivors without statistical significance, but were not associated with 5-year mortality. CONCLUSIONS The presence of dilated cardiomyopathy, elevated CVP at 48 h and reduced CRP levels on day 7 predicted 5-year mortality in patients who developed postoperative LCOS after cardiac surgery. NT-proBNP levels in the first postoperative week were not predictors of long-term outcomes.

Abstract
UNLABELLED In children during the first months of life delayed sternum closure is one of the few techniques increasing cardiac output after simultaneous correction of complex congenital heart defects (CHD). The aim of study was evaluating mortality, predictors of adverse outcome and frequency noncardial complications at of delayed sternum closure after correction of CHD. METHODS Study design: a prospective, uncontrolled, cohort. 22 children were studied 6 children died. Anesthesia was carried out on the basis ofpropofol (3 mg/kg/h) and fentanyl (5 pg/kg/h) infusion with sevoflurane inhalation in a dose of 1-1.5 WT, including during perfusion. Cardiopulmonary bypass (IR) was carried out by the "Stockert S50" using oxygenators ("Medtronic"). After IR in all cases the use of arterio--venous modified ultrafiltration. Sternum closure was performed on average 2.7 ± 1.4 days after surgery. RESULTS The odds ratio (OR) of death development at the mean arterial pressure (MAP) < 35 Hg was 3.7, the OR for the risk of death development if SVO₂ < 40% was 0.94. OR for risk of death when blood lactate level > 10 mmol/l during the first three days ofpostoperative intensive care was 2.1. CONCLUSIONS The technique of delayed sternum closure is an acceptable method of maintaining cardiac output in children during the first months of life with CHD in the postoperative period. High blood lactate level (> 10 mmol/l) and especially its further growth and the MAP < 35 mm Hg can be predictors of adverse outcomes of surgical interventions with an open sternotomy.

Abstract
INTRODUCTION Levosimendan is implemented in patients with low cardiac output after cardiac surgery. However, the strength of evidence is limited by randomized controlled trials enrolling a small number of patients. Hence we have conducted a systematic review to determine the role of levosimendan in adult cardiac surgery. METHODS PUBMED, WoS, Cochrane database, and SCOPUS were systematically queried to identify original English language peer-reviewed literature (inception-October 2014) comparing clinical results of adult cardiac surgery between levosimendan and control. Pooled odds ratio (OR) was calculated using the Peto method; p < 0.05 is significant; results are presented within 95% confidence intervals. Continuous data was compared using standardized mean difference/mean difference. RESULTS Fourteen studies were included in the analysis. Levosimendan reduced early mortality in patients with reduced ejection fraction (5.5% vs. 9.1%) (OR 0.48 [0.23-0.76]; p = 0.004). This result was confirmed using sensitivity analysis. Postoperative acute renal failure was lower with levosimendan therapy (7.4% vs. 11.5%). Intensive care unit stay was shorter in the levosimendan cohort comparable in both groups (standardized mean difference -0.31 [-0.53, -0.09]; p = 0.006; I(2) = 33.6%). Levosimendan-treated patients stayed 1.01 (1.61-0.42) days shorter when compared to control (p = 0.001). CONCLUSION Our meta-analysis demonstrates that Levosimendan improves clinical outcomes in patients with left ventricular dysfunction undergoing cardiac surgery. Results of the ongoing multicenter randomized controlled trial are awaited to provide more conclusive evidence regarding the benefit of this drug.

Abstract
BACKGROUND Children with congenital heart disease often undergo heart surgery at a young age. They are at risk for postoperative low cardiac output syndrome (LCOS) or death. Milrinone may be used to provide inotropic and vasodilatory support during the immediate postoperative period. OBJECTIVES This review examines the effectiveness of prophylactic postoperative use of milrinone to prevent LCOS or death in children having undergone surgery for congenital heart disease. SEARCH METHODS Electronic and manual literature searches were performed to identify randomised controlled trials. We searched CENTRAL, MEDLINE, EMBASE and Web of Science in February 2014 and conducted a top-up search in September 2014 as well as clinical trial registries and reference lists of published studies. We did not apply any language restrictions. SELECTION CRITERIA Only randomised controlled trials were selected for analysis. We considered studies with newborn infants, infants, toddlers, and children up to 12 years of age. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data according to a pre-defined protocol. We obtained additional information from all study authors. MAIN RESULTS Three of the five included studies compared milrinone versus levosimendan, one study compared milrinone with placebo, and one compared milrinone verus dobutamine, with 101, 242, and 50 participants, respectively. Three trials were at low risk of bias while two were at higher risk of bias. The number and definitions of outcomes were non-uniform as well. In one study comparing two doses of milrinone and placebo, there was some evidence in an overall comparison of milrinone versus placebo that milrinone lowered risk for LCOS (risk ratio (RR) 0.52, 95% confidence interval (CI) 0.28 to 0.96; 227 participants). The results from two small studies do not provide enough information to determine whether milrinone increases the risk of LCOS when compared to levosimendan (RR 1.22, 95% CI 0.32 to 4.65; 59 participants). Mortality rates in the studies were low, and there was insufficient evidence to draw conclusions on the effect of milrinone compared to placebo or levosimendan or dobutamine regarding mortality, the duration of intensive care stay, hospital stay, mechanical ventilation, or maximum inotrope score (where available). Numbers of patients requiring mechanical cardiac support were also low and did not allow a comparison between studies, and none of the participants of any study received a heart transplantation up to the end of the respective follow-up period. Time to death within three months was not reported in any of the included studies. A number of adverse events was examined, but differences between the treatment groups could not be proven for hypotension, intraventricular haemorrhage, hypokalaemia, bronchospasm, elevated serum levels of liver enzymes, or a reduced left ventricular ejection fraction < 50% or reduced left ventricular fraction of shortening < 28%. Our analysis did not prove an increased risk of arrhythmias in patients treated prophylactically with milrinone compared with placebo (RR 3.59, 95% CI 0.83 to 15.42; 238 participants), a decreased risk of pleural effusions (RR 1.78, 95% CI 0.92 to 3.42; 231 participants), or a difference in risk of thrombocytopenia on milrinone compared with placebo (RR 0.86, 95% CI 0.39 to 1.88; 238 participants). Comparisons of milrinone with levosimendan or with dobutamine, respectively, did not clarify the risk of arrhythmia and were not possible for pleural effusions or thrombocytopenia. AUTHORS' CONCLUSIONS There is insufficient evidence of the effectiveness of prophylactic milrinone in preventing death or low cardiac output syndrome in children undergoing surgery for congenital heart disease, compared to placebo. So far, no differences have been shown between milrinone and other inodilators, such as levosimendan or dobutamine, in the immediate postoperative period, in reducing the risk of LCOS or death. The existing data on the prophylactic use of milrinone has to be viewed cautiously due to the small number of small trials and their risk of bias.

Abstract
Although the outcome of neonatal cardiac surgery has dramatically improved, low body weight (LBW) is still considered an important risk for open heart surgery. The factors contributing to poor outcomes in LBW infants, however, are still unclear. We investigated risk factors for poor outcomes in infants weighing <2500 g who underwent surgical correction with cardiopulmonary bypass (CPB). From January 1995 to December 2009, 102 consecutive patients were included in this study. Median age and body weight at the time of surgery was 19 (range 1 to 365) days and 2.23 kg (range 1.3 to 2.5), respectively. Corrective surgery was performed on 75 infants. The median follow-up duration was 45.03 months (range 0.33 to 155.23). There were 23 (22.5%) hospital mortalities. Emergency surgery and low cardiac output (LCO) were associated with early mortality; however, body weight, Aristotle basic complex score, and type of surgery was not. Early morbidities, including delayed sterna closure, arrhythmia, and chylothorax, occurred in 39 (38.2%) infants. The overall actuarial survival rate at 10 years was 74.95% ± 4.37%. In conclusion, among infants weighing <2500 g who underwent open heart surgery with CPB, perioperative hemodynamic status, such as emergency surgery and LCO, strongly influenced early mortality. In contrast, LBW itself was not associated with patient morbidity or mortality.

Abstract
OBJECTIVE During open heart surgery, direct transthoracic insertion of the intra-aortic balloon pump (IABP) is an alternative to the routine transfemoral insertion especially in the presence of severe peripheral vascular disease. METHODS Over 19 years (1980-1998), 646 patients were treated with IABP. In 24 of them, the balloon was inserted transthoracic (TIABP) due to failure of transfemoral insertion in 13 or extensive occlusive aorto-iliac disease in 11 cases. RESULTS Early mortality was 58.3% in patients having TIABP compared to 46.1% in patients with transfemoral IABP insertion (p > 0.2). Of the 24 patients receiving IABP transthoracic, none suffered vascular injury (i.e. perforation or dissection). Complications which could be related to TIABP occurred in 10 patients: 3 balloon ruptures, 1 mediastinal haemorrhage, 3 cerebrovascular accidents, 1 post-operative mediastinitis, and 2 late graft infections. CONCLUSIONS TIABP is a useful alternative when transfemoral insertion of IABP is not feasible or hazardous because of occluded or severely diseased ilio-femoral arteries. Being a second choice and a more invasive treatment, transthoracic IABP is associated with increased mortality.

Abstract
BACKGROUND Mitral valve (MV) repair is considered to provide more favorable results than MV replacement. MV repair in a patient with severe left ventricular (LV) dysfunction could be associated with higher early and late mortality. Surgical indication of MV repair for those with low LV ejection fraction (LVEF) is still controversial. PATIENTS AND METHODS Fifty-two patients with severe mitral regurgitation (MR) and severe LV dysfunction (EF < 35%) underwent MV repair with or without concomitant procedure. The commonest etiology of MV disease was ischemic origin (78.8%), which underwent annuloplasty alone. Their pre- and perioperative parameters were analyzed to identify the risk factor for mortality. The follow-up data of hospital survivors were collected. RESULTS Early mortality was 9.6%. The cause of all deaths was low cardiac output syndrome. Actuarial survival was 81.6% at 2 years and 76.5% at 5 years. Multivariate analyses revealed chronic hemodialysis and EF < 25% to be the risk factors for early and late mortality. Among hospital survivors, significant improvement of LVEF (29.9 to 37.4%) and reduction of LV diastolic dimension (62.8 to 57.9 mm) were observed during follow-up. CONCLUSION MV repair is effective to improve long-term prognosis of high-risk patients of severe MR with severe LV dysfunction.

Abstract
AIM Rheumatic mitral patients reach their fifth decade of life more often now than in the past. The purpose of this study is to provide insight into improving morbidity and mortality in these patients. METHODS This retrospective study included 105 patients aged 50 years or more. Seventy-five underwent mechanical valve replacement and 30 received a bioprosthetic valve. Data were collected from medical records and outpatient department (OPD) registers. Follow-up included transthoracic 2D echocardiography, supported by clinical parameters, and X-ray findings. RESULTS Mean age was 58.52+/-2.4 years. Follow-up period ranged from one to eleven years (mean 6.8+/-0.9 years). Immediate perioperative mortality included five patients (4.76%) and long term mortality included three patients (3%). 35 patients previously underwent closed and open commissurotomy and balloon valvotomy. Multivariate analysis showed age, repeat surgery, atrial fibrillation, tricuspid valve disease, and preoperative functional status to be incremental risk factors. Freedom from repeat operation at 3 and 6 years was 90% and 85% in group I (<60 years), respectively. Actuarial survival at 4 and 6 years of follow up was 94.24% and 88.52%, respectively. CONCLUSION With improving life expectancy and early interventions, the number of < or = 50-year old rheumatic valvular disease patients is increasing. The present study showed a marked improvement for this subset of patients, although age still remains the main risk factor along with atrial fibrillation, repeat surgery, stroke and tricuspid valve disease.

Abstract
Much of the mortality following myocardial infarction results from remodeling of the heart after the acute ischemic event. Cardiomyocyte apoptosis has been thought to play a key role in this remodeling process. In this issue of the JCI, Diwan and colleagues present evidence that Bnip3, a proapoptotic Bcl2 family protein, mediates cardiac enlargement, reshaping, and dysfunction in mice without influencing infarct size.

Abstract
BACKGROUND AND OBJECTIVE The incidence of heart failure is increasing in developed countries. In the aged population, heart failure is a common cause of hospitalization and hospital readmission, which in conjunction with post-discharge care, impose a significant cost burden. Inappropriate medication management and drug-related problems have been identified as major contributors to hospital readmissions. In order to enhance the care and clinical outcomes, and reduce treatment costs, heart failure disease management programmes (DMPs) have been developed. It is recommended that these programmes adopt a multi-disciplinary approach, and pharmacists, with their understanding and knowledge of medication management, can play a vital role in the post-discharge care of heart failure patients. The aim of this literature review was to assess the role of pharmacists in the provision of post-charge services for heart failure patients. METHOD An extensive literature search was undertaken to identify published studies and review articles evaluating the benefits of an enhanced medication management service for patients with heart failure post-discharge. RESULTS Seven studies were identified evaluating 'outpatient' or 'post-discharge' pharmacy services for patients with heart failure. In three studies, services were delivered prior to discharge with either subsequent telephone or home visit follow-up. Three studies involved the role of a pharmacist in a specialist heart failure outpatient clinic. One study focused on a home-based intervention. In six of these studies, positive outcomes, such as decreases in unplanned hospital readmissions, death rates and greater compliance and medication knowledge were demonstrated. One study did not show any difference in the number of hospitalizations between intervention and control groups. The quality of evidence of the randomized controlled trials was assessed using the Jadad scoring method. None of the studies achieved a score of more than 2, out of a maximum of 5, indicating the potential for bias. DISCUSSION The DMPs carried out by pharmacists have contributed to positive patient outcomes, which has highlighted the value of extending the traditional roles of pharmacists from the provision of professional guidance to the delivery of continuity of care through a more holistic and direct approach. CONCLUSION This review has demonstrated the effectiveness of pharmacists' interventions to reduce the morbidity and mortality associated with heart failure. However, there is an on-going need for the development and evaluation of pharmacy services for these patients.

Abstract
INTRODUCTION Although it is known that patients with diastolic heart failure are at an increased risk of death, their mode of death has not been clearly defined. We conducted this study to examine the incidence and predictors of sudden cardiac death (SCD) in patients with isolated diastolic heart failure. METHODS AND RESULTS Using the Duke Databank for Cardiovascular Disease, we identified patients with a history of congestive heart failure (CHF) and an ejection fraction of greater than 50% who were enrolled in the database from 1995 through 2004. Mode of death was adjudicated by two independent reviewers. Of the 1,941 patients who met our inclusion criteria, 548 (28%) died (40 were SCD). Using a Cox proportional hazards model, five variables were found to be independently associated with a significant increase in the risk of SCD. These variables include diabetes mellitus (P < 0.01), the presence of mild mitral regurgitation (P < 0.01), severity of CHF (P < 0.01), the occurrence of a myocardial infarction within 3 days prior to the date of the index cardiac catheterization (P = 0.01), and severity of coronary artery disease (P = 0.02). CONCLUSIONS SCD is not uncommon in patients with isolated diastolic heart failure. We identified some clinical variables that are associated with a significant increase in the risk of SCD and that may be used in the risk stratification of patients for SCD. Studies are needed to validate our findings.

Abstract
BACKGROUND Diastolic heart failure (DHF) and systolic heart failure (SHF) are 2 clinical subsets of the syndrome of chronic heart failure that are most commonly encountered in clinical practice. METHODS AND RESULTS The clinically overt DHF and SHF appear to be 2 separate syndromes with distinctive morphologic and functional changes although signs, symptoms, and prognosis are very similar. In DHF, the left ventricle is not dilated and the ejection fraction is preserved. In contrast in SHF, it is dilated and the ejection fraction is reduced. The neurohormonal abnormalities in DHF and SHF appear to be similar. The stimuli and the signals that ultimately produce these 2 different phenotypes of chronic heart failure remain, presently, largely unknown. CONCLUSIONS Although there has been considerable progress in the management of SHF, the management of DHF remains mostly empirical because of lack of knowledge of the molecular and biochemical mechanisms which produce myocardial structural and functional changes in this syndrome. Further research and investigations are urgently required.

Abstract
Decreased left ventricular (LV) function is a strong predictor of mortality. Although current guidelines recommend prophylactic implantable cardioverter-defibrillator (ICD) implantation after ST-elevation myocardial infarction and a depressed LV ejection fraction for 1 month, the prognoses of these patients may be better than those observed in randomized trials of ICDs (1-year mortality 6.8% to 19%), particularly because reperfusion treatment has improved, and the use of life-saving drugs is higher. To assess 1-year mortality in patients with depressed LV ejection fractions after primary percutaneous coronary intervention, a prospective, observational study was performed. Data from all patients who survived >/=30 days after primary percutaneous coronary intervention and had LV ejection fractions </=30% from 1994 to 2004 were recorded. Of 2,544 patients, 342 (13%) had LV ejection fractions </=30%. One-year mortality was 5.8%. Sudden death was the most common cause of death (40%). Patients who died more often had multivessel disease and a higher incidence of recurrent myocardial infarction within 1 year. In conclusion, current mortality in patients with depressed LV ejection fractions after primary percutaneous coronary intervention is much better than that observed in previous ICD trials, and the benefits of ICD therapy in these patients should be further evaluated.

Abstract
BACKGROUND Levosimendan (LS) improves cardiac contractility without increasing myocardial oxygen demand. We administrated LS on a monthly intermittent 24-hour protocol and evaluated the clinical effect after 6 months in a randomized, open, prospective study. METHODS AND RESULTS Fifty patients (age 45-65 years) with LV systolic dysfunction and New York Heart Association (NYHA) III or IV were randomized in 2 groups. LS group (n = 25) was compared with a control group (n = 25) matched for sex, age, and NYHA class. LS was given monthly on a 24-hour intravenous protocol for 6 months. Patients were evaluated by specific activity questionnaire (SAQ) and echocardiography (ECHO) before and 3 to 5 days after last drug administration, whereas 24-hour Holter recording was performed before and during last drug administration. Patients in LS and control group had same baseline SAQ, ECHO, and Holter parameters. At the end of the study, a larger proportion of patients in the levosimendan group reported improvement in symptoms (dyspnea and fatigue) (65% versus 20% in controls, P < .01). After 6 months, the LS group had a significant increase in LV ejection fraction versus controls (28 +/- 7 versus 21 +/- 4 %, P = .003), LV shortening fraction (15 +/- 3 versus 11 +/- 3 %, P = .006) and a decrease in mitral regurgitation (1.5 +/- 0.8 versus 2.7 +/- 0.6, P = .0001). There was no increase in supraventricular or ventricular beats or supraventricular tachycardia and VT episodes in LS group, compared with controls. Two patients from the LS group died in the 6-month follow-up period, compared with 8 patients in the control group (8% versus 32%, P < .05). CONCLUSIONS A 6-month intermittent LS treatment in patients with decompensated advanced heart failure improved symptoms and LV systolic function.

Abstract
Arterial hypertension is the leading cause of mortality and morbidity with a worldwide prevalence of 26%. Aging increases the incidence of arterial hypertension. Arterial hypertension is the prime example for a chronic disease with asymptomatic beginning, creeping course and fatal outcome. Arterial hypertension is a major cardiovascular risk factor and leads to vascular as well as myocardial manifestations: coronary artery disease, hypertensive microvascular disease, concentric left ventricular hypertrophy as well as perivascular and interstitial fibrosis. In the late stages of the disease, hypertrophy and cardiac failure develop. Arterial hypertension is the leading cause of coronary artery disease and cardiac failure, and coronary artery disease is the cause of heart failure in 50% of cases. Various non-invasive and invasive procedures are available for screening and follow-up. The primary therapeutic target is to reverse cardiac manifestations of arterial hypertension using specific therapeutic algorithms as well as lowering blood pressure. This article covers the pathophysiology of arterial hypertension and cardiac failure, clinical symptoms, diagnostic options and therapeutical goals as well as medicinal options.

Abstract
Background—
Undertreatment with recommended pharmacotherapy is a common problem in heart failure and may influence prognosis. We studied initiation and persistence of evidence-based pharmacotherapy in 107 092 patients discharged after first hospitalization for heart failure in Denmark from 1995 to 2004.
Methods and Results—
Prescriptions of dispensed medication and mortality were identified by an individual-level linkage of nationwide registers. Inclusion was irrespective of left ventricular function. Treatment with renin-angiotensin inhibitors (eg, angiotensin-converting enzyme inhibitors and angiotensin-2 receptor blockers), β-blockers, spironolactone, and statins was initiated in 43%, 27%, 19%, and 19% of patients, respectively. Patients who did not initiate treatment within 90 days of discharge had a low probability of later treatment initiation. Treatment dosages were in general only 50% of target dosages and were not increased during long-term treatment. Short breaks in therapy were common, but most patients reinitiated treatment. Five years after initiation of treatment, 79% patients were still on renin-angiotensin inhibitors, 65% on β-blockers, 56% on spironolactone, and 83% on statins. Notably, multiple drug treatment and increased severity of heart failure was associated with persistence of treatment. Nonpersistence with renin-angiotensin inhibitors, β-blockers, and statins was associated with increased mortality with hazard ratios for death of 1.37 (95% CI, 1.31 to 1.42), 1.25 (95% CI, 1.19 to 1.32), 1.88 (95% CI, 1.67 to 2.12), respectively.
Conclusions—
Persistence of treatment was high once medication was started, but treatment dosages were below recommended dosages. Increased severity of heart failure or increased number of concomitant medications did not worsen persistence, but nonpersistence identified a high-risk population of patients who required special attention. A focused effort on early treatment initiation, appropriate dosages, and persistence with the regimen is likely to provide long-term benefit.

Abstract
The importance of resting heart rate (HR) as a prognostic factor and potential therapeutic target is not yet generally accepted. Recent large epidemiologic studies have confirmed earlier studies that showed resting HR to be an independent predictor of cardiovascular and all-cause mortality in men and women with and without diagnosed cardiovascular disease. Clinical trial data suggest that HR reduction itself is an important mechanism of benefit of beta-blockers and other heart-rate lowering drugs used after acute myocardial infarction, in chronic heart failure, and in stable angina pectoris. Pathophysiological studies indicate that a relatively high HR has direct detrimental effects on the progression of coronary atherosclerosis, on the occurrence of myocardial ischemia and ventricular arrhythmias, and on left ventricular function. Studies have found a continuous increase in risk with HR above 60 beats/min. Although it may be difficult to define an optimal HR for a given individual, it seems desirable to maintain resting HR substantially below the traditionally defined tachycardia threshold of 90 or 100 beats/min. These findings suggest that the potential role of HR and its modulation should be considered in future cardiovascular guidance documents.

Abstract
OBJECTIVES To assess differences in clinical characteristics, treatment and outcome between men and women with heart failure (HF) treated at a multidisciplinary HF unit. All patients had their first unit visit between August 2001 and April 2004. PATIENTS We studied 350 patients, 256 men, with a mean age of 65 +/- 10.6 years. In order to assess the pharmacological intervention more homogeneously, the analysis was made at one year of follow-up. RESULTS Women were significantly older than men (69 +/- 8.8 years vs. 63.6 +/- 10.9 years, p < 0.001). Significant differences were found in the HF etiology and in co-morbidities. A higher proportion of men were treated with ACEI (83% vs. 68%, p < 0.001) while more women received ARB (18% vs. 8%, p = 0.006), resulting in a similar percentage of patients receiving either of these two drugs (men 91% vs. women 87%). No significant differences were observed in the percentage of patients receiving beta-blockers, loop diuretics, spironolactone, anticoagulants, amiodarone, nitrates or statins. More women received digoxin (39% vs. 22%, p = 0.001) and more men aspirin (41% vs. 31%, p = 0.004). Carvedilol doses were higher in men (29.4 +/- 18.6 vs. 23.8 +/- 16.4, p = 0.03), ACEI doses were similar between sexes, and furosemide doses were higher in women (66 mg +/- 26.2 vs. 56 mg +/- 26.2, p < 0.05). Mortality at 1 year after treatment analysis was similar between sexes (10.4% men vs. 10.5% women). CONCLUSIONS Despite significant differences in age, etiology and co-morbidities, differences in treatment between men and women treated at a multidisciplinary HF unit were small. Mortality at 1 year after treatment analysis was similar for both sexes.

Abstract
INTRODUCTION AND OBJECTIVES Anemia is a common finding in outpatients with heart failure (HF) and is associated with increased mortality. The aims of this study were to identify determinants of the hemoglobin level in a large group of hospitalized patients with systolic HF and to investigate the medium-term prognostic value of the hemoglobin level. METHODS The study included 460 consecutive patients (age 68.3 [12.3] years, 74% male) who were hospitalized with a diagnosis of HF and left ventricular systolic dysfunction (i.e., a left ventricular ejection fraction <45%). At hospital discharge, biochemical and hematological parameters were measured and clinical and echocardiographic variables were recorded. Patients were followed up for 16.8[9.7] months. RESULTS Anemia, as defined by World Health Organization criteria, was present in 189 (41.1%) patients. The following independent determinants of the hemoglobin level were identified: age (relative risk [RR]=1.035, 95% CI, 1.011-1.060; P=.004), female sex (RR=1.843, 95% CI, 1.083-3.135; P=.024), diabetes mellitus (RR=1.413, 95% CI, 1.087-1.838; P=.010), plasma urea level (RR=1.013, 95% CI, 1.005-1.022; P=.001), and loop diuretic use (RR=2.801, 95% CI, 1.463-5.364; P=.002). A decrease in hemoglobin level was associated with increased risks of death (RR per g/dL=1.232, 95% CI, 1.103-1.375; P<.001) and death or HF readmission (RR per g/dL=1.152, 95% CI, 1.058-1.255; P<.001), but not with readmission for non-fatal HF (RR per g/dL=1.081, 95% CI, 0.962-1.215; P=.265). Blood transfusion during hospitalization did not alter the increased risk of death (RR=2.19, 95% CI 1.40-3.41; P=.001). CONCLUSIONS In hospitalized patients with systolic HF, the hemoglobin level at hospital discharge was an independent predictor of death in the medium term, but not of readmission for non-fatal HF. The main determinants of the hemoglobin level were age, sex, renal function, diabetes, and the need for diuretics.

Abstract
In large-scale randomized trials and their meta-analyses, beta-adrenergic blockers and angiotensin-converting enzyme inhibitors provide statistically significant and clinically important additive mortality and morbidity benefits in the treatment of heart failure. The CHARM trials were designed to test whether the angiotensin-receptor blocker candesartan would provide statistically significant and clinically important additive mortality and morbidity benefits to patients with heart failure as an alternative or in addition to angiotensin-converting enzyme inhibitors. CHARM demonstrated that an angiotensin-receptor blocker at a proven dose is an effective and safe therapy as an alternative or in addition to angiotensin-converting enzyme inhibitors in patients with heart failure, 55% of whom were receiving beta-adrenergic blockers. These benefits include reductions in cardiovascular mortality rate as well as in hospitalization for heart failure. Such patients have a 50% mortality rate at 5 years, and heart failure is the leading cause of hospitalization for patients 65 years of age and older.

Abstract
BACKGROUND Heart failure (HF) is associated with poor outcome after acute myocardial infarction (AMI). Women have higher mortality rate than men after AMI, however, it is unknown whether women with HF after AMI have different prognosis than men. AIM To compare the prognosis of men and women with AMI and mild-moderate HF. METHODS We analyzed data of 3456 consecutive patients with AMI hospitalized in all cardiac care units in Israel during two nationwide surveys. RESULTS Among patients with AMI and HF on admission: women were older, had more risk factors, and were less likely to undergo percutaneous coronary angiography/intervention. Women with HF had higher (7-days, 30-days, and 1-year) crude mortality rates than men. However, adjusted mortality rates were not significantly different between genders. CONCLUSIONS Women with AMI complicated by HF had higher crude mortality rate than men that was eliminated after multivariate analysis, suggesting that the higher mortality rate may be attributed to increased prevalence of risk factors and lower rate of revascularization and medical therapies among women. Women with AMI and HF should be considered as a high-risk subgroup with adverse outcome. It remains to be determined whether more intensive management will improve their prognosis.

Abstract
BACKGROUND The characteristics and outcomes of patients discharged from hospitals with a diagnosis of heart failure (HF) have been described by a number of previous epidemiological studies. However, very little information is available on this issue in general practice in Japan. METHODS AND RESULTS The Japanese Cardiac Registry of Heart Failure in General Practice (JCARE-GENERAL) is designed to study the characteristics, treatment and outcomes prospectively in a broad sample of outpatients with HF who were managed by cardiologists in hospital (Hospital-HF) and primary care physicians in general practice (GP-HF). Out of 2,685 patients with HF, 1,280 patients were Hospital-HF and 1,405 GP-HF. Compared to the Hospital-HF patients, GP-HF patients were more likely to be elderly and female, and they had a higher prevalence of hypertensive heart disease as a cause of HF. Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and beta-blockers were more prescribed to Hospital-HF than GP-HF patients. At the follow-up of 1.2 year, after adjustment, the mortality was comparable between the Hospital-HF and GP-HF groups, whereas HF-related admission was higher in the Hospital-HF group than in in the GP-HF group. CONCLUSIONS Based on the JCARE-GENERAL, the characteristics, treatment and outcomes of GP-HF patients differed from those of Hospital-HFpatients in Japan.

Abstract
When comparing two groups, one receiving an experimental intervention and the other a placebo or nothing, researchers often wish to assess the disparity in risk of experiencing an event of interest, such as onset of disease. Relative risk, relative risk reduction, and odds ratio are often used to measure the association between potential benefit or harm and the intervention. However, these summary measures reflect relative disparities and are perhaps less useful in clinical practice than measures of absolute benefit or harm. We demonstrate that relative risk reduction is unaffected by the risk of an event in the control group and hence may either overestimate or underestimate the treatment effect. Absolute risk reduction accounts for the baseline control group event rate and is a more realistic quantification of treatment effect than relative measures. Number needed to treat (NNT) estimates the therapeutic effort needed to prevent one additional adverse event. NNT incorporates both relative risk reduction and the event rate without treatment. For a given relative risk reduction, we demonstrate the NNT will increase as the control event rate decreases. Thus, NNT has more-obvious implications for clinical decision making than risk estimates expressed in relative terms.

METHODS AND RESULTS We prospectively enrolled 146 patients with chronic heart failure, an ICD, and systolic dysfunction (mean ejection fraction 29 +/- 10%). Cardiac death was chosen as the primary endpoint. Death or appropriate ICD therapy, i.e. antitachycardia pacing/shock due to sustained ventricular tachycardia or ventricular fibrillation, was chosen as the secondary endpoint. Seventy-five patients (52%) had chronic kidney disease (defined as an estimated glomerular filtration rate <60 mL/min/1.73 m(2)), 39 patients (27%) were anaemic, and 34 patients (23%) had diabetes mellitus. During a follow-up of 663 +/- 400 days, 22 patients (15%) died, and 41 patients (28%) received an appropriate ICD therapy. By multivariate Cox analysis, independent predictors of cardiac death were chronic kidney disease, age, and NYHA functional class. Death/appropriate ICD therapy were independently predicted by chronic kidney disease and QRS duration. In the presence of chronic kidney disease, outcome was significantly worse when compared with the absence (event-free survival rate 51 vs. 76%, P < 0.001). CONCLUSION In heart failure patients with an ICD, comorbidities are frequent but only the presence of chronic kidney disease is independently associated with increased morbidity and mortality.

Abstract
BACKGROUND Digoxin reduces hospitalizations due to heart failure (HF) and may also reduce mortality at low serum digoxin concentrations (SDC). Most HF patients are > or = 65 years, yet the effects of digoxin on outcomes in these patients have not been well studied. METHODS Of the 7788 ambulatory chronic HF patients in normal sinus rhythm in the Digitalis Investigation Group trial (1991-1995), 5548 (2890 were > or = 65 years) were alive at 1 month and were either receiving placebo or had data on SDC. Of these patients, 982 had low (0.5-0.9 ng/mL) and 705 had high (> or = 1 ng/mL) SDC. RESULTS Among patients > or = 65 years, compared with 38% placebo patients, 34% low SDC patients died during 39 months of median follow-up (adjusted hazard ratio [AHR] = 0.81; 95% confidence interval [CI] = 0.68-0.96; p =.017). All-cause hospitalizations occurred in 70% of placebo and 68% of low-SDC patients (AHR = 0.86; 95% CI = 0.76-0.98; p =.019). Reduction in hospitalizations for HF occurred in both low and high SDC groups. High SDC was not independently associated with all-cause hospitalization or all-cause mortality. Age, impaired renal function, and pulmonary congestion reduced the odds of low SDC. Low-dose digoxin (< or = 0.125 mg/d) was the strongest independent predictor of low SDC (adjusted odd ratio = 2.37; 95% CI = 1.65-3.39); p <.0001). CONCLUSIONS Digoxin at low SDC was associated with a reduction in mortality and hospitalization in chronic geriatric HF, and low-dose digoxin was the strongest predictor of low SDC.

Abstract
This article provides information and a commentary on trials relevant to the pathophysiology, prevention and treatment of heart failure, presented at the American College of Cardiology meeting in March 2007. Unpublished reports should be considered as preliminary data, as analyses may change in the final publication. The ALPHA study suggested that patients with heart failure (HF) due to idiopathic dilated cardiomyopathy who have a negative T-wave alternans test have a good prognosis and are unlikely to benefit from ICD therapy. EVEREST provides some evidence of short-term symptom benefit of tolvaptan in patients with acute decompensated HF but no clinically important long-term benefit. FUSION II failed to show a benefit of nesiritide in patients with chronic decompensated HF. Reducing blood pressure in hypertensive patients improved diastolic dysfunction in VALIDD. Eplerenone did not improve left ventricular remodelling in mild to moderate chronic HF. Selecting HF patients for revascularisation using FDG-PET imaging did not significantly improve outcome. Crataegus extract added to standard HF therapy did not reduce morbidity or mortality in SPICE. The COURAGE study, conducted in patients without HF or major cardiac dysfunction, showed that PCI did not reduce cardiac morbidity or mortality and can be safely deferred in patients with stable coronary disease on optimal medical therapy. The COACH study failed to show that HF nurse-intervention could reduce hospitalisations but did show trends to lower mortality, especially amongst patients with reduced ejection fraction; however, the smaller REMADHE study suggested striking benefits on morbidity and mortality. A large study of BNP provided additional information on its ability to distinguish cardiac and pulmonary breathlessness. The importance of dietary intervention in post-MI patients was highlighted by the findings of THIS-diet study.

Abstract
OBJECTIVE To assess the applicability of three prognostic indexes--APACHE II, SAPS II and UNICAMP II--in a subgroup of critical heart failure (HF) patients. METHODS Ninety patients were studied, being 12 females and 78 males. Mean age was 56 (18-83). Patients were ranked in functional class IV (NYHA) or cardiogenic shock secondary to cardiomyopathies: dilated (44%), chagasic (25.5%), ischemic (18%), hypertensive (1.1%), hypertrophic (1.1%), alcoholic (1.1%), and secondary to valvopathies after surgical correction (7.7%). Tables with frequency of categorical variables and descriptive statistics of continuous variables were created in order to describe sample profile for the different variables under study. In order to analyze the relationship between prognostic indexes levels and course towards death, an analysis of the ROC curve, as well as Hosmer and Lemeshow Test of Goodness of Fit calculated, and Standardized Mortality Ratio (SMR) were carried out. RESULTS The statistical analysis showed low sensitivity, specificity, and accuracy of the three prognostic indexes for HF patients. Mortality was underestimated in this group. Pulmonary thromboembolism (PTE) was a major factor of mortality rate in severe HF. CONCLUSION The three prognostic indexes under study did not prove to be appropriate for the assessment of cardiopathy patients at Intensive Care Unit (ICU). For HF patients, PTE played a major role in mortality of heart failure. Specific prognostic indexes for cardiopathy patients with severe HF should be proposed, and the discussion on anticoagulation on those patients should be expanded.

Abstract
AIMS In patients with heart failure (HF), the association between sudden death and arrhythmic pattern at 24-h Holter monitoring [number of ventricular premature contractions per hour (VPCs/h) and presence of non-sustained ventricular tachycardia (NSVT)] has previously been investigated with conflicting results. Since both VPCs/h and NSVT disregard the time course of arrhythmic events, we developed a new index based on the short-term peak rate of ectopies and investigated its prognostic power in HF patients. METHODS AND RESULTS We studied 200 HF patients in sinus rhythm [age: [median (interquartile range)] 54 years [47-58], left ventricular ejection fraction (LVEF): 23% [19-28], New York Heart Association (NYHA) class II-III: 88%]. For each patient, the Holter recording was automatically scanned shifting a 30 beat window one beat at a time, and the maximum number of ectopic beats found in a window was named peak ectopy rate (PEAK_ER). The association between PEAK_ER and sudden death was assessed by Cox proportional hazards regression analysis. Survival analysis was also carried out adjusting for NYHA class, aetiology, LVEF, left ventricular end diastolic diameter, blood urea nitrogen, amiodarone, Digoxin, beta-blockers, NSVT, VPCs/h, and the standard deviation of all normal-to-normal beats. During a 5-year follow-up [31 (12-60) months], 23 patients died of sudden death. Out of the arrhythmic markers, PEAK_ER but not VPCs/h and NSVT was significantly associated with sudden death in univariable analysis (RR: 1.08, 95% CI: 1.02-1.14, P = 0.005) and after adjustment for covariates (RR: 1.09, 95% CI: 1.03-1.15, P = 0.004). CONCLUSIONS The investigation of the time course of arrhythmic events provides independent information in the identification of patients at increased risk of sudden death and may therefore be considered in the development of treatment strategies in HF patients.

Abstract
Recent studies suggest that anemia is an independent predictor of adverse outcomes in patients with heart failure (HF), but the importance of anemia in elderly HF patients is unclear. To investigate this relationship, the authors quantified the prognostic importance of anemia in elderly vs younger patients with HF was performed. A chart review of 359 patients hospitalized in 1999 with HF was performed. Patients were categorized based on their hemoglobin (Hgb) level (<11.5, 11.5-13.4, >13.4 g/dL), and the authors used time-to-event analyses to test the hypothesis that Hgb predicted mortality over a mean follow-up of 25 months. Lower Hgb predicted worse survival in patients younger than 75 years (n=204; P=.03), but there was no correlation between Hgb level and mortality in patients 75 or older (n=155; P not significant). The authors conclude that anemia is not an important predictor of long-term survival in very elderly patients hospitalized with HF.

Abstract
BACKGROUND An increase in circulating B-type natriuretic peptide (BNP) is associated with a poor outcome in patients with acute heart failure. The primary aim of this study was to investigate the prognostic value of BNP levels in patients with chronic and advanced heart failure. METHODS Fifty patients with New York Heart Association functional classes III and IV were enrolled in the study. Their blood BNP levels at admission were measured and patients were on follow up for 12 +/- 2 months. RESULTS There was no significant correlation between BNP levels on admission and left ventricular ejection fraction (r = 0.12, P > 0.05). Twelve patients (24%) died during the follow up. BNP levels were lower in patients who died (501 +/- 72 vs 877 +/- 89 ng/L, P < 0.01). The logistic stepwise regression analysis showed that lower BNP level (<520 ng/L) on admission was an independent predictor of cardiovascular mortality in these patients (odds ratio 1.21, 95% confidence interval 1.06-2.32, P < 0.01). CONCLUSION We conclude that patients with chronic and advanced heart failure have a lower circulating BNP level than those who survive. The paradoxically low BNP level is an adverse prognostic marker in advanced heart failure.

Abstract
Acute heart failure syndromes (AHFS) are a major public health problem and present a therapeutic challenge to clinicians. Commonly used agents in the treatment of AHFS include diuretics, vasodilators (eg, nitroglycerin, nitroprusside, nesiritide), and inotropes (eg, dobutamine, dopamine, milrinone). Patients admitted to hospital with AHFS and low cardiac output state (AHFS/LO) represent a subgroup with very high inhospital and postdischarge mortality rates. Most of these patients require intravenous inotropic therapy. However, the use of current intravenous inotropes has been associated with risk for hypotension, atrial and ventricular arrhythmias, and possibly increased postdischarge mortality, particularly in those with coronary artery disease. Consequently, there is an unmet need for new agents to safely improve cardiac performance (contractility and/or active relaxation) in this patient population. This article reviews a selection of current and investigational agents for the treatment of AHFS, with a main focus on the high-risk patient population with AHFS/LO.

Abstract
Development of heart failure (HF) or left ventricular systolic dysfunction (LVSD) significantly increases mortality post acute myocardial infarction (AMI). Aldosterone contributes to the development and progression of HF post AMI, and major guidelines now recommend aldosterone blockade in this setting. However, lack of practical experience with aldosterone blockade may make clinicians hesitant to use these therapies. This review is based on a consensus cardiology conference that occurred in May 2005 (New York City) concerning these topics. Potential barriers to the use of aldosterone blockade are discussed and an algorithm for appropriate in-hospital pharmacologic management of AMI with LVSD and/or HF is presented.

Abstract
INTRODUCTION AND OBJECTIVES The objective was to determine what percentage of patients admitted for heart failure met criteria for cardiac resynchronization therapy. METHODS The study involved registry data on heart failure admissions at 16 public hospitals in Andalusia, Spain between May and July 2004. Criteria for cardiac resynchronization therapy from American College of Cardiology and American Heart Association guidelines were applied: a left ventricular ejection fraction < or = 0.35, New York Heart Association functional class III or IV, and a QRS interval > 120 ms. Outcome was evaluated at 3 months. Multivariate (i.e., logistic regression) analysis was used to identify independent variables associated with meeting resynchronization therapy criteria. RESULTS The study included 674 patients (43.3% women, mean age 71[11] years). Of these, 5.6% met resynchronization therapy criteria at admission. There was no significant difference in the cardiovascular event rate at 3 months between patients who met resynchronization therapy criteria and those who did not (34.2% vs 23.4%, respectively). Admitting hospital (odds ratio [OR]=0.30, 95% confidence interval [CI], 0.11-0.79), ischemic etiology (OR=2.71, 95% CI, 1.26-5.81), the presence of left bundle branch block (OR=14.97, 95% CI, 5.95-37.64), and mitral regurgitation (OR=4.18, 95% CI, 1.93-9.04) were all independently associated with meeting resynchronization therapy criteria at both admission and short-term follow-up. CONCLUSIONS The percentage of patients who met cardiac resynchronization therapy criteria was small, but their short-term prognosis was poor. A number of clinical variables associated with meeting resynchronization therapy criteria were identified.

Abstract
BACKGROUND The incidence of diastolic heart failure (DHF) is increasing with the aging of the community and identifying patients with isolated diastolic dysfunction (IDD) is important for preventing DHF. However, very little information is available about such patients in the Japanese community. METHODS AND RESULTS The medical information of all outpatients with moderate to severe IDD was extracted from the records of approximately 6,948 individuals who underwent echocardiographic (Echo) examinations during the past 5 years in Sado Island. Of the 284 patients extracted, 272 survived until 2003. In January 2003 the proportion of patients with moderate to severe IDD in the general population sector aged 45-84 years was 0.9% for males and 0.5% for females, and this proportion increased sharply after the age of 65 in both genders, reaching 1.6% for men in their 70 s and 0.8% for women in their 80 s. On Echo, 165 patients (61%) showed hypertrophic left ventricular geometry. The Charlson comorbidity index score was < or = 1 in 63% of patients. The cumulative survival of IDD patients, irrespective of a history of congestive heart failure (HF), was significantly lower than in the general population. CONCLUSIONS Moderate to severe IDD is not uncommon in the elderly and has a poor prognosis. Characteristics of outpatients with IDD should be taken into consideration when establishing a preventive strategy for HF in the Japanese community.
