Repeated or intermittent levosimendan treatment in advanced heart failure: An updated meta-analysis.

Abstract Introduction Advanced heart failure is a malignant disease characterized by a debilitating late course, with increasingly frequent hospitalisations and high rate of mortality. Levosimendan, an inodilator developed for the treatment of acutely decompensated chronic heart failure, has been recently proposed also as a repetitive treatment of advanced heart failure. Several studies on the use of levosimendan in this settings report mortality data. Independent meta-analyses on the effect on mortality of repetitive or intermittent levosimendan administration in advanced heart failure has been published but were criticized in regard to the selection of the studies. Meanwhile new data became available. We therefore updated the selection of studies and re-analyzed all the available data. Methods & results Data from seven randomized trial and a total of 438 adult patients using intermittent levosimendan in a cardiological setting were included in the present analysis. The average follow-up period was 8±3.8months. The use of levosimendan was associated with a significant reduction in mortality at the longest follow-up available [41 of 257 (16%) in the levosimendan group vs. 39 of 181 (21.5%) in the control arm, OR=0.54 (95% CI 0.32–0.91), p for effect=0.02, p for heterogeneity=0.64, I2=0%]. Conclusions The updated results suggest that repetitive or intermittent levosimendan administration in advanced heart failure is associated with a significant reduction in mortality at the longest follow-up available. There is therefore a strong rationale for a randomized clinical trial with adequate power on mortality

Relation of Use of Red Blood Cell Transfusion After Acute Coronary Syndrome to Long-Term Mortality

Registry studies have associated red blood cell (RBC) transfusion with increased in hospital mortality in patients with acute coronary syndrome (ACS). The impact on long-term mortality after 1-year follow-up remains unknown. Consecutive patients with ACS (n = 2,009) of a prospective Genetic Predisposition of Coronary Artery Disease cohort were followed for a median of 8.6 years (95% confidence interval [CI] 8.59 to 8.69). After discharge, 1,937 (96%) patients survived for over 30 days. Of those survivors, a subgroup of previously transfusion-nave patients 85/1,937 (4.4%) who had received at least 1 RBC transfusion during hospitalization were compared with 1,278/1,937 patients (66.0%) who had not received any transfusion either during the hospitalization or the entire follow-up. Unadjusted long-term mortality was significantly higher in the patients transfused with RBC compared with their counterparts not transfused with RBC (58.8% vs 20.3%, pPeer reviewe

Cardiac steatosis associates with visceral obesity in nondiabetic obese men.

Background: Liver fat and visceral adiposity are involved in the development of the metabolic syndrome (MetS). Ectopic fat accumulation within and around the heart has been related to increased risk of heart disease. The aim of this study was to explore components of cardiac steatosis and their relationship to intra-abdominal ectopic fat deposits and cardiometabolic risk factors in nondiabetic obese men. Methods: Myocardial and hepatic triglyceride (TG) contents were measured with 1.5 T magnetic resonance spectroscopy, and visceral adipose (VAT), abdominal subcutaneous tissue (SAT), epicardial and pericardial fat by magnetic resonance imaging in 37 men with the MetS and in 40 men without the MetS. Results: Myocardial and hepatic TG contents, VAT, SAT, epicardial fat volumes, and pericardial fat volumes were higher in men with the MetS compared with subjects without the MetS (P < .001). All components of cardiac steatosis correlated with SAT, VAT, and hepatic TG content and the correlations seemed to be strongest with VAT. Myocardial TG content, epicardial fat, pericardial fat, VAT, and hepatic TG content correlated with waist circumference, body mass index, high-density lipoprotein cholesterol TGs, very low-density lipoprotein-1 TGs, and the insulin-resistance homeostasis model assessment index. VAT was a predictor of TGs, high-density lipoprotein cholesterol, and measures of glucose metabolism, whereas age and SAT were determinants of blood pressure parameters. Conclusions: We suggest that visceral obesity is the best predictor of epicardial and pericardial fat in abdominally obese subjects. Myocardial TG content may present a separate entity that is influenced by factors beyond visceral adiposity

The Metabolome in Finnish Carriers of the MYBPC3-Q1061X Mutation for Hypertrophic Cardiomyopathy

Aims Mutations in the cardiac myosin-binding protein C gene (MYBPC3) are the most common genetic cause of hypertrophic cardiomyopathy (HCM) worldwide. The molecular mechanisms leading to HCM are poorly understood. We investigated the metabolic profiles of mutation carriers with the HCM-causing MYBPC3-Q1061X mutation with and without left ventricular hypertrophy (LVH) and non-affected relatives, and the association of the meta-bolome to the echocardiographic parameters. Methods and Results 34 hypertrophic subjects carrying the MYBPC3-Q1061X mutation, 19 non-hypertrophic mutation carriers and 20 relatives with neither mutation nor hypertrophy were examined using comprehensive echocardiography. Plasma was analyzed for molecular lipids and polar metabolites using two metabolomics platforms. Concentrations of branched chain amino acids, triglycerides and ether phospholipids were increased in mutation carriers with hypertrophy as compared to controls and non-hypertrophic mutation carriers, and correlated with echocardiographic LVH and signs of diastolic and systolic dysfunction in subjects with the MYBPC3-Q1061X mutation. Conclusions Our study implicates the potential role of branched chain amino acids, triglycerides and ether phospholipids in HCM, as well as suggests an association of these metabolites with remodeling and dysfunction of the left ventricle.Peer reviewe
