OBJECTIVES: Left ventricular ejection fraction (EF) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are important surrogate markers of cardiac function and wall stress. Randomized trials of heart failure (HF) have shown improvements in survival in patients with reduced EF (<40%, HFrEF) but not with preserved EF (≥50%, HFpEF) or mid-range EF (40-49%, HFmrEF). Limited information is available on the trajectory of EF in contemporary heart failure management programs (HFMPs)...

OBJECTIVE: Endothelial function, including the nitric oxide (NO)-pathway, has previously been extensively investigated in heart failure (HF). In contrast, studies are lacking on the NO pathway after heart transplantation (HT). We therefore investigated substances in the NO pathway prior to and after HT in relation to hemodynamic parameters. DESIGN: 12 patients (median age 50.0 yrs, 2 females), heart transplanted between June 2012 and February 2014, evaluated at our hemodynamic lab, at rest, prior to HT, as well as four weeks and six months after HT were included...

OBJECTIVE: We aim to determine the correlation between ST-segment changes in leads V4-V6 and the extent of myocardial injury by cardiac magnetic resonance (CMR) in patients with inferior ST elevation (STE) myocardial infarction (iSTEMI). DESIGN: Admission electrocardiogram and CMR data from the MITOCARE trial were used. Differences in mean myocardium at risk, infarct size, ejection fraction and myocardial segment involvement by CMR were compared in patients with first iSTEMI with STE, ST depression (STD) or no ST changes (NST) in V4-V6...

OBJECTIVES: With a steadily growing number of patients with non-valvular atrial fibrillation, anticoagulation use increases. Anticoagulation therapy is associated with increased risk of serious bleeding and an increased complexity in management of patients in need for urgent surgery. We wanted to assess the magnitude of this challenge as well as review current and potential future clinical management strategies. DESIGN: A review of the literature on the magnitude of patients using antigoaculants in potential need for acute restoration of hemostasis was conducted, as well as current status of reversal agents for non-vitamin K antagonist oral anticoagulants (NOACs)...

OBJECTIVE: Temporal variations in the occurrence of out-of-hospital cardiac arrest (OHCA) have been shown. Most previous studies have in common that they include individuals whom have received cardiopulmonary resuscitation (CPR) and thus excluding a great number of all the actual cases of OHCA when conducting a study. Therefore the aim of this study was to describe temporal variations of OHCA, regardless of whether CPR was performed or not. DESIGN: All individuals aged 25-74 years in northern Sweden, 1989-2009, who suffered an out-of-hospital cardiac arrest with validated myocardial infarction aetiology (OHCA-V), regardless of whether CPR was performed or not, were included in this study, which resulted in 3357 individuals...

OBJECTIVES: Arterial stiffness has emerged as a surrogate marker of cardiovascular disease. We investigated the role of myocardial performance and hemodynamic parameters in arterial stiffness in patients with rheumatoid arthritis (RA), which is accompanied by excess cardiovascular risk. DESIGN: Arterial stiffness was evaluated with pulse wave velocity (PWV) in RA patients and controls. Cardiac and hemodynamic characterization was based on impedance cardiography...

OBJECTIVE: Comorbidity prior to out-of-hospital cardiac arrest (OHCA) and primary rhythm in relation to survival is not well established. We aimed to assess the prognostic importance of comorbidity in relation to primary rhythm in OHCA-patients treated with Target Temperature Management (TTM). DESIGN: Consecutive comatose survivors of OHCA treated with TTM in hospitals in the Copenhagen area between 2002-2011 were included. Utstein-based pre- and in-hospital data collection was performed...

OBJECTIVES: Late gadolinium enhancement (LGE) is the in vivo reference standard for assessing focal myocardial fibrosis. Post-contrast T1-mapping by Modified Look-Locker Inversion recovery (MOLLI) can be used to generate synthetic late gadolinium enhancement (SynLGE) images with an image contrast similar to conventional LGE images. We hypothesized that SynLGE has an accuracy that approaches conventional LGE for diagnosing focal myocardial fibrosis. METHODS: Consecutive patients (n = 109, mean ± SD age 50 ± 16 years, 63% male) referred for clinical cardiac magnetic resonance imaging underwent LGE and post-contrast MOLLI starting 10-15 and 20-25 minutes post contrast, respectively...

OBJECTIVES: Haemodynamic monitoring during post arrest care is important to optimise treatment. We compared stroke volume measured by minimally-invasive monitoring devices with or without thermodilution calibration, and transthoracic echocardiography (TTE), and hypothesised that thermodilution calibration would give stroke volume index (SVI) more in agreement with TTE during targeted temperature management (TTM). DESIGN: Comatose out-of-hospital cardiac arrest survivors receiving TTM (33 °C for 24 hrs) underwent haemodynamic monitoring with arterial pulse contour analyses with (PiCCO2®) and without (FloTrac® /Vigileo® monitor® ) transpulmonary thermodilution calibration...

OBJECTIVES: Saphenous vein grafts (SVGs) most often used in coronary artery bypass grafting (CABG) are subject to graft disease and have poor long-term patency, however the clinical implication of this is not completely known. We aim to assess the influence of graft failure on the postoperative recurrence of coronary artery disease (CAD) symptoms in relation to the contribution from progression of atherosclerosis in the native coronary vessels. DESIGN: Within the SWEDEHEART registry we identified 46,663 CABG cases between 2001 and 2015 with patient age 40-80 years where single internal mammary artery (IMA) anastomosis (IMA), single IMA with one (1SVG) or multiple SVG anastomoses (2+ SVG) had been performed...

OBJECTIVE: Oxygen (O2 ) have been a cornerstone in the treatment of acute myocardial infarction. Studies have been inconclusive regarding the cardiovascular and analgesic effects of oxygen in these patients. In the SOCCER trial, we compared the effects of oxygen treatment versus room air in patients with ST-elevation myocardial infarction (STEMI). There was no difference in myocardial salvage index or infarct size assessed with cardiac magnetic resonance imaging. In the present subanalysis, we wanted to evaluate the effect of O2 on chest pain in patients with STEMI...

OBJECTIVE: Atherosclerosis is a systemic inflammatory disease that can affect more than one arterial bed simultaneously. The aim of this study was to determine the relationship between ultrasound markers of atherosclerosis and multiple arterial disease. DESIGN: We have included 87 currently asymptomatic carotid disease patients (mean age 69 ± 6 year, 34% females) in this study. Intima media thickness (IMT) and intima media-grey scale median (IM-GSM) were measured in the common carotid artery (CCA), and correlated with previous and/or current atherosclerotic vascular disease in the coronary, carotid and lower extremities...

OBJECTIVES: Infective endocarditis (IE) has a high 30-day mortality. Surgery is needed in many patients. The preoperative hemodynamic status (congestive heart failure, need for urgent/emergent surgery or mechanical support, NYHA class III/IV) could have an impact on postoperative outcome. Each of these parameters is an indication for the inadequacy of the left ventricle to maintain an adequate circulation Methods. A literature search was performed using "endocarditis AND hospital mortality OR outcome AND predictor" and "International Collaboration on Endocarditis - Prospective Cohort Study" in Web of Science database, from 2010-2017...

OBJECTIVE: The use of pre-hospital ECGs (PH-ECG) reduces time to reperfusion for patients with ST-segment elevation myocardial infarction (STEMI). The feasibility of reperfusion therapy within 60 minutes for hospitals with 24/7 PCI capability has been questioned, and current guidelines have set time targets to 90 minutes. Our primary objective was to investigate the proportion of false-positive catheterization laboratory activations by PH-ECG. Our secondary objective was to describe the time intervals from first medical contact to reperfusion and to establish the proportion of patients receiving reperfusion within 60 minutes...
