OBJECTIVE: Peripartum cardiomyopathy (PPCM) is left ventricular (LV) systolic dysfunction with an ejection fraction of ≤45% occurring in the later stages of pregnancy or soon after delivery. Although various risk factors have been identified, the exact cause of the disease is unknown. Unlike most countries in the European region, Turkey has yet to determine the current PPCM burden. A registry for this purpose does not exist. To close this gap, the A RegisTry of pEripartuM cardIomyopathy in Turkish patientS (ARTEMIS-I and ARTEMIS-II), was planned and endorsed by the Turkish Society of Cardiology...

Aims: Mechanical dyssynchrony has been reported in heart failure with preserved ejection fraction (HFpEF), with a majority of patients having a narrow QRS complex; however, whether any benefit is observed with restoration of dyssynchrony remains unclear. We sought to assess left ventricular (LV) dyssynchrony and function in HFpEF and elucidate the underlying mechanisms that may account for HFpEF. Methods: Seventy-eighty patients with a narrow QRS complex including 47 with HFpEF, 31 with heart failure with reduced ejection fraction (HFrEF) patients, and 29 with asymptomatic left ventricular diastolic dysfunction (LVDD) were recruited...

Serelaxin has been studied in trials in adults with acute heart failure, but not in children. We report the first compassionate use of serelaxin in an infant. A 6-month-old girl with dilated cardiomyopathy was placed on extracorporeal membrane oxygenation following cardiac arrest unresponsive to medical treatment. Extracorporeal membrane oxygenation weaning failed despite maximal ino-dilator therapy. During the 48-hour infusion of serelaxin, we observed marked improvement in brain natriuretic peptide, left ventricular systolic function, and dilatation...

BACKGROUND: Transient receptor potential vanilloid 2 is a calcium channel activated by probenecid. Probenecid is a Food and Drug Administration-approved uricosuric drug that has recently been shown to induce positive lusitropic and inotropic effects in animal models through cardiomyocyte transient receptor potential vanilloid 2 activation. The aim of this study was to test the hypothesis that oral probenecid can improve cardiac function and symptomatology in patients with heart failure with reduced ejection fraction and to further elucidate its calcium-dependent effects on myocyte contractility...

BACKGROUND: Postresuscitation myocardial dysfunction (PRMD) can develop after successful resuscitation from cardiac arrest. However, echocardiographic patterns of PRMD remain unknown. This study aimed to investigate PRMD manifestations with serial echocardiography during the post-cardiac arrest period. METHODS: We enrolled non-traumatic out-of-hospital cardiac arrest patients older than 19 years who underwent successful cardiopulmonary resuscitation (CPR). We excluded patients with myocardial infarction or pre-existing cardiac disease, including heart failure or myocardial disease...

We have previously developed a simulated cardiovascular physiology model for in-silico testing and validation of novel closed-loop controllers. To date, a detailed model of the right heart and pulmonary circulation was not needed, as previous controllers were not intended for use in patients with cardiac or pulmonary pathology. With new development of controllers for vasopressors, and looking forward, for combined vasopressor-fluid controllers, modeling of right-sided and pulmonary pathology is now relevant to further in-silico validation, so we aimed to expand our existing simulation platform to include these elements...

Almost 25% of patients with heart failure (HF) have coexisting atrial fibrillation (AF), the latter of which may increase morbidity and mortality. Despite the high prevalence of HF with concomitant AF, this subgroup of patients remains understudied. This study examines gender differences in presentation, treatment and in-hospital outcome of patients with HF and AF. The Get With the Guidelines-Heart Failure (GWTG-HF) database enrolled 6,496 patients with HF who presented to Cooper University Hospital from 2005 to 2012...

An interaction between the intestine and cardiovascular disease has been suggested. We thought to clarify the association between intestinal conditions and clinical outcomes in patients with heart failure (HF). Hemodynamic parameters in intestinal vessels [superior mesenteric artery (SMA), inferior mesenteric artery (IMA), and portal vein (PV)] and average colon wall thickness (aCWT) from the ascending colon to sigmoid colon were evaluated in 224 hospitalized HF patients. Echocardiographic parameters and composite event rates (all-cause mortality, readmission for HF deterioration, major ventricular arrhythmias) were also examined...

Though most patients presenting for liver transplantation have normal left ventricular function, some develop left ventricular failure after transplantation. The primary objective of our study was to determine the predictors of systolic heart failure occurring immediately after liver transplantation. Its etiology, prospects of recovery and factors associated with non-recovery were also studied. Liver transplantations performed at our institution from 01/2006 to 02/2015 were evaluated using prospectively collected institutional registries...

BACKGROUND: In heart failure (HF) with reduced ejection fraction, right ventricular (RV) impairment, as defined by reduced tricuspid annular plane systolic excursion, is a predictor of poor outcome. However, peak longitudinal strain of RV free wall (RVFWS) has been recently proposed as a more accurate and sensitive tool to evaluate RV function. Accordingly, we investigated whether RVFWS could help refine prognosis of patients with HF with reduced ejection fraction in whom tricuspid annular plane systolic excursion is still preserved...

Adipose tissue lipolysis occurs during the development of heart failure as a consequence of chronic adrenergic stimulation. However, the impact of enhanced adipose triacylglycerol hydrolysis mediated by adipose triglyceride lipase (ATGL) on cardiac function is unclear. To investigate the role of adipose tissue lipolysis during heart failure, we generated mice with tissue-specific deletion of ATGL (atATGL-KO). atATGL-KO mice were subjected to transverse aortic constriction (TAC) to induce pressure-mediated cardiac failure...

BACKGROUND: Although heart failure (HF) prevalence is equally high among men and women, observed differences in the provision of care are still not fully understood. We sought to evaluate gender differences in patient profiles, diagnostic testing, medication prescription, and referrals in specialized multidisciplinary ambulatory HF clinics in Ontario. MATERIALS AND METHODS: Medical chart abstraction was conducted first by randomly selecting 9 (out of 34) HF clinics in Ontario, and then by randomly selecting 100 patient records in each clinic...

Uncertainties still remain in terms of the efficacy of anti-hypertensive treatment on the risk of major cardiovascular (CV) events within prehypertensive levels. This review aims to assess the efficacy and safety of anti-hypertensives on the CV risks in populations within prehypertensive levels. Randomized controlled trials (RCTs) concerning active treatment vs placebo in populations within prehypertensive levels were identified through electronic database and manual search. Outcomes included the first co-primary outcomes, stroke, heart failure (HF), myocardial infarction (MI), all-cause mortality, and cardiovascular mortality...

PURPOSE: Reduced blood circulation is an important feature of heart failure, and Doppler stroke distance of the left ventricular outflow tract is a measure of forward stroke volume. Several echocardiographic parameters have known prognostic implications in heart failure, but the prognostic implications of stroke distance in relation to other parameters are insufficiently known. The aim was therefore to test the hypothesis that stroke distance is associated with five-year all-cause mortality, independently of other echocardiography variables, and that stroke distance has added long-term prognostic value...

BACKGROUND: Observational data have described the association of blood pressure (BP) with mortality as 'J-shaped', meaning that mortality rates increase below a certain BP threshold. We aimed to analyse the associations between BP and prognosis in a population of acute myocardial infarction (MI) patients with heart failure (HF) and/or systolic dysfunction. METHODS AND RESULTS: The datasets included in this pooling initiative are derived from four trials: CAPRICORN, EPHESUS, OPTIMAAL, and VALIANT...

D Sellers, C Srinivas, G Djaiani
Cardiac complications are common after non-cardiac surgery. Peri-operative myocardial infarction occurs in 3% of patients undergoing major surgery. Recently, however, our understanding of the epidemiology of these cardiac events has broadened to include myocardial injury after non-cardiac surgery, diagnosed by an asymptomatic troponin rise, which also carries a poor prognosis. We review the causation of myocardial injury after non-cardiac surgery, with potential for prevention and treatment, based on currently available international guidelines and landmark studies...

AIMS: Increasing age is an established prognostic determinant in chronic heart failure (HF). Diabetes often complicates HF in its course and appears to worsen HF prognosis. A differential impact of diabetes depending on patients' age was not yet studied. We evaluated the impact of diabetes in the mortality of HF patients according to their age. METHODS: We studied a cohort of chronic ambulatory HF patients prospectively recruited. Patients were on optimized evidence-based therapy, and they were excluded if on renal replacement therapy or if they had any therapy modification or hospitalizations in the previous 2 months...
