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...

BACKGROUND: The coronary slow flow phenomenon (CSFP) is well-documented, and the early repolarization pattern (ERP) has recently been shown to be a risk factor for the development of malignant ventricular arrhythmias. METHODS: Those with true CSFP were included as cases and those with normal angiograms were included as controls. We assessed J-point elevation on surface electrocardiograms (ECGs) and defined ERP as notching or slurring of the terminal portion of the QRS takeoff...

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...

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...

OBJECTIVE: Elevated systolic pulmonary artery pressure (sPAP) is common among elderly patients with cardiac and pulmonary diseases. The lowest level of sPAP associated with increased mortality rate in octogenarians with cardiac diseases is however not sufficiently studied. Therefore, the present study aimed to identify the lowest level of sPAP associated with increased 5-year all-cause mortality in this patient group. DESIGN: Of 538 octogenarians presented at the three Sahlgrenska University Hospitals (Sahlgrenska, Östra and Mölndal) with either congestive heart failure (CHF) or acute coronary syndrome (ACS), only 302 patients who had undergone echocardiography with data on sPAP were included in the present study...

Venous return, the right heart function and the pulmonary circulation is an integrated functional unit. The right ventricle is particularly load sensitive, and will be influenced directly by the venous and pulmonary physiology. In this paper we present important physiological principles that govern the diagnosis and treatment of dysfunctions affecting the return of blood to the heart and the transfer of the cardiac output from the right to the left side. We do evaluate both basic science and the clinical literature pointing to practical aspects of physiological knowledge...

OBJECTIVES: Heart failure is a significant cause of mortality worldwide, and most current therapies treat only its symptoms. The results of cardiac stem cell research suggest a promising treatment option for heart failure, but there is currently an unmet demand for better research models. We have therefore, for the first time, isolated, expanded and differentiated progenitor cells obtained from juvenile pig hearts to use as a platform for cardiac stem cell research. DESIGN: Progenitor cells were isolated from the left ventricles of porcine hearts using collagenase enzymatic digestion and Percoll® -gradient centrifugation...

OBJECTIVE: Changes in right ventricular (RV) structure and function following prolonged endurance training in athletes arise due to its unique anatomy and physiology. Arrhythmogenic cardiomyopathy (AC) should be differentiated from electrical, functional and structural adaptation of the heart in response to repetitive intense physical activity due to the negative contribution of exercise on AC progression and arrhythmic risk. DESIGN: For this review we performed a systematic search of the PubMed database up to October 2017 using terms and keywords pertaining to RV, athlete's heart (AH), AC, sudden cardiac death...
