The effect of excessive trabeculation on cardiac rotation-A multimodal imaging study.

Background: Cardiac rotational parameters in primary symptomatic left ventricular noncompaction (LVNC) with preserved left ventricular ejection fraction (LVEF) are not well understood. We aimed to analyze cardiac rotation measured with cardiac magnetic resonance feature-tracking (CMR-FT) and speckle-tracking echocardiography (Echo-ST) in LVNC morphology subjects with preserved LVEF and different genotypes and healthy controls.

Methods: Our retrospective study included 54 LVNC subjects with preserved LVEF and 54 control individuals.

Apolipoprotein A1 Infusions and Cardiovascular Outcomes after Acute Myocardial Infarction.

Background: Cardiovascular events frequently recur after acute myocardial infarction, and low cholesterol efflux - a process mediated by apolipoprotein A1, which is the main protein in high-density lipoprotein - has been associated with an increased risk of cardiovascular events. CSL112 is human apolipoprotein A1 derived from plasma that increases cholesterol efflux capacity. Whether infusions of CSL112 can reduce the risk of recurrent cardiovascular events after acute myocardial infarction is unclear.

Highlights of right ventricular characteristics of left ventricular noncompaction using 3D echocardiography.

The aspects of right ventricular volumes and function investigated with 3D echocardiography in a large cohort of left ventricular noncompaction morphology (LVNC) population remains unclear. The objective of our research was to study the left (LV) and right (RV) ventricular parameters using 3D echocardiography and analyze the clinical features of a LVNC population with preserved LV ejection fraction (EF > 50 %) in comparison with healthy controls (HC). We selected 41 LVNC subjects with preserved LV function (EF: 52.

Characteristics of the right ventricle in left ventricular noncompaction with reduced ejection fraction in the light of dilated cardiomyopathy.

Background: Reports of left ventricular noncompaction (LVNC) rarely include descriptions of the right ventricle (RV). This study aimed to describe the characteristics of the RV in LVNC patients with reduced LV function (LVNC-R) compared with patients with dilated cardiomyopathy (DCM) and subjects with LVNC with normal left ventricular ejection fraction (LV-EF) (LVNC-N).

Methods: Forty-four LVNC-R patients, 44 LVNC-N participants, and 31 DCM patients were included in this retrospective study (LV-EF: LVNC-R: 33.

Calcium scoring on coronary computed angiography tomography with photon-counting detector technology: Predictors of performance.

Introduction: Obtaining accurate coronary artery calcium (CAC) score measurements from CCTA datasets with virtual non-iodine (VNI) algorithms would reduce acquisition time and radiation dose. We aimed to assess the agreement of VNI-derived and conventional true non-contrast (TNC)-based CAC scores and to identify the predictors of accuracy.

Methods: CCTA datasets were acquired with either 120 or 140 ​kVp.

May Strenuous Endurance Sports Activity Damage the Cardiovascular System of Healthy Athletes? A Narrative Review.

The positive effects of physical activity are countless, not only on the cardiovascular system but on health in general. However, some studies suggest a U-shape relationship between exercise volume and effects on the cardiovascular system. On the basis of this perspective, moderate-dose exercise would be beneficial compared to a sedentary lifestyle, while very high-dose physical activity would paradoxically be detrimental.

Impact of Right Ventricular Trabeculation on Right Ventricular Function in Patients With Left Ventricular Non-compaction Phenotype.

Right ventricular (RV) involvement in left ventricular (LV) non-compaction (LVNC) remains unknown. We aimed to describe the RV volumetric, functional, and strain characteristics and clinical features of patients with LVNC phenotype and good LV ejection fraction (EF) using cardiac magnetic resonance to characterize RV trabeculation in LVNC and to study the relationships of RV and LV trabeculation with RV volume and function. This retrospective study included 100 Caucasian patients with LVNC phenotype and good LV-EF and 100 age- and sex-matched healthy controls.

MR -specific characteristics of left ventricular noncompaction and dilated cardiomyopathy.

Background: The differentiation of dilated cardiomyopathy (DCM) and left ventricular noncompaction (LVNC) is a recurring issue during cardiac imaging processes; thus, we aimed to compare the left ventricular (LV) cardiac MRI characteristics of these patients.

Methods: Thirty-one nonischemic DCM patients, 42 LVNC patients with reduced ejection fraction and 42 healthy controls were included in this retrospective study. LV volumetric, functional and myocardial mass parameters were measured with a threshold-based technique, while global and segmental strain values and rotational patterns were analyzed with feature-tracking strain analysis.

Age- and Sex-Specific Characteristics of Right Ventricular Compacted and Non-compacted Myocardium by Cardiac Magnetic Resonance.

The age and sex-specific characteristics of right ventricular compacted (RV-CMi) and RV-trabeculated myocardial mass (RV-TMi) and the determinants of RV myocardium are less well-studied; however, in different conditions, these might provide additional diagnostic information. We aimed to describe the age- and sex-specific characteristics of RV-CMi, RV-TMi, and RV volumetric and functional parameters and investigate the determinants of RV myocardial mass with cardiac magnetic resonance (CMR). Two hundred healthy Caucasian volunteers free of known cardiovascular or systemic diseases were prospectively enrolled in this study.

Sex- and age- specific normal values of left ventricular functional and myocardial mass parameters using threshold-based trabeculae quantification.

Background: The threshold-based (TB) trabeculated and papillary muscle mass (TPM) quantification method for cardiac MRI (CMR) calculates different values than conventional contouring techniques. We aimed to identify the sex- and age-related normal reference ranges for left ventricular (LV) myocardial mass values, volumetric and functional parameters and the correspondence of these parameters using the TB method.

Methods: Healthy European adults (n = 200, age: 39.

Changes in strain parameters at different deterioration levels of left ventricular function: A cardiac magnetic resonance feature-tracking study of patients with left ventricular noncompaction.

Background: There is a lack of cardiac MRI information on left ventricular (LV) strain and rotational parameters of left ventricular noncompaction (LVNC) patients with reduced ejection fraction (EF). Thus, we sought to use feature tracking (FT) to describe these changes at different levels of EF deterioration.

Methods: We included 31 adult LVNC patients with reduced LV EF (Group B, EF < 50%) without any comorbidities or concomitant cardiac diseases, 31 age- and sex-matched LVNC patients with good EF (Group A, EF > 50%) and 31 healthy controls.

Association between Cyclothymic Affective Temperament and Age of Onset of Hypertension.

Affective temperaments represent a biologically stable core of emotional reactivity and have previously been associated with hypertension and arterial stiffening. The age, when hypertension is initiated, is influenced by different factors, but the role of personality traits in this regard is not clarified yet. Our aim was to study the association between affective temperaments and the age at onset of hypertension.

Long-term single-centre large volume experience with transseptal endocardial left ventricular lead implantation.

Aims: The aim of our study was to investigate the long-term efficacy and safety of transseptal endocardial left ventricular lead implantation (TELVLI).

In 36 cases, the transseptal puncture (TP) was performed via the femoral vein, and in 18 cases, the TP and also the left ventricular (LV) lead placement were performed via the subclavian vein.

Antibody-Mediated Rejection in a Multiple Lung Transplant Patient: A Case Report.

Lung transplant is an effective way to treat many end-stage lung diseases. However, one of the main barriers of allograft organ transplant is still the immunologic rejection of transplanted tissue, which is a response of the HLA molecules. Rejection is a complex process involving both T-cell-mediated delayed-type hypersensitivity reactions and antibody-mediated hypersensitivity reactions to histocompatibility molecules on foreign grafts.

Donation After Cardiac Death, a Possibility to Expand the Donor Pool: Review and the Hungarian Experience.

Introduction: Lung transplantation is the only successful treatment option for patients experiencing end-stage lung disease. Results have improved significantly in the last decade; however, the number one limiting factor is still the shortage of donor lungs. Due to the discrepancy between available donor lungs and patients awaiting lung transplantation, many centers have reintroduced donation after cardiac death (DCD).

Lung Transplant Patients on Kilimanjaro.

Background: After its initial difficulties were overcome, lung transplantation became an accepted and effective treatment for end-stage lung disease. Patients can take part in almost all kinds of sports after lung transplantation, including high-altitude mountaineering, which is an extreme sport even for healthy individuals. Several articles have been published about high-altitude tolerance of transplanted patients.

First 3 Years of the Hungarian Lung Transplantation Program.

Patients And Methods: The first lung transplant in Hungary was carried out on December 12, 2015, with the collaboration of the National Institute of Oncology and the Semmelweis University. Up to December 31, 2018, a total of 62 lung transplants were performed.

G-protein Coupled Receptor Signaling in Pluripotent Stem Cell-derived Cardiovascular Cells: Implications for Disease Modeling.

Human pluripotent stem cell derivatives show promise as an in vitro platform to study a range of human cardiovascular diseases. A better understanding of the biology of stem cells and their cardiovascular derivatives will help to understand the strengths and limitations of this new model system. G-protein coupled receptors (GPCRs) are key regulators of stem cell maintenance and differentiation and have an important role in cardiovascular cell signaling.

Inflammation and oxidative stress caused by nitric oxide synthase uncoupling might lead to left ventricular diastolic and systolic dysfunction in patients with hypertension.

Objective: To investigate the role of oxidative stress, inflammation, hypercoagulability and neuroendocrine activation in the transition of hypertensive heart disease to heart failure with preserved ejection fraction (HFPEF).

Methods: We performed echocardiography for 112 patients (≥ 60 years old) with normal EF (18 controls and 94 with hypertension), and determined protein carbonylation (PC), and tetrahydrobiopterin (BH4), C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), fibrinogen, plasminogen activator inhibitor type-I (PAI-I), von Willebrand factor, chromogranin A (cGA) and B-type natriuretic peptide (BNP) levels from their blood samples.

Results: We found that 40% (38/94) of the patients with hypertension (HT) had no diastolic dysfunction (HTDD-), and 60% (56/94) had diastolic dysfunction (HTDD+).
