: Available data suggest the diagnostic potential of testing microRNAs (miRs) in myocardial infarction, but their prognostic value remains unclear. To evaluate the prognostic value of circulating miRs (miR-1, miR-21, miR-133a, miR-208 and miR-499) for predicting major adverse cardiac events (MACEs), including death, non-fatal myocardial infarction (MI) or cardiovascular rehospitalization, in patients with non-ST segment elevation acute coronary syndromes (NSTE-ACS). Our prospective, single-center, observational study included patients (pts) with NSTE-ACS admitted <24 h after symptoms onset and pts with confirmed stable coronary artery disease (SCAD) as controls.

Methods: Sixty-one consecutive patients with acute coronary syndrome were enrolled in the present study (43 men, mean age 61 ± 9 years). All patients underwent percutaneous coronary intervention (PCI).
Background: An impairment of standard echocardiographic parameters of right ventricular (RV) function is a known phenomenon in patients undergoing cardiac surgery, but its significance remains unclear.
Aims: This study aimed to assess changes in RV function in patients undergoing cardiac surgery using speckle tracking and 3D echocardiography.
Methods: The study population comprised 122 patients referred for cardiac surgery.
The aim of this study was to assess the accuracy of an algorithm for automated measurement of left ventricular ejection fraction (LVEF) available on handheld ultrasound devices (HUDs). One hundred twelve patients admitted to the cardiology department underwent assessment performed with an HUD. In each case, the four-chamber apical view was obtained, and LVEF was calculated with LVivo software.

The aim of this study was to test whether the results of FMSF show a relationship with the eAHI in patients with coronary artery disease or aortic stenosis.
Methods: Twenty-one patients (12 coronary disease, 9 aortic stenosis) and 37 healthy volunteers were included.

Background: Stroke volume response during stress is a major determinant of functional status in heart failure and can be measured by two-dimensional (2-D) volumetric stress echocardiography (SE). The present study hypothesis is that SE may identify mechanisms underlying the change in stroke volume by measuring preload reserve through end-diastolic volume (EDV) and left ventricular contractile reserve (LVCR) with systolic blood pressure and end-systolic volume (ESV).
Methods: We enrolled 4735 patients (age 63.
High specific mechanical properties of composites are the reason for their use in various fields, e.g., the aerospace industry.
View Article and Find Full Text PDFBackground: The rotation and twist of the left ventricle (LV) have been comprehensively evaluated at rest. However, little is known about rotational mechanics during dobutamine stress echocardiography (DSE).
Aims: We aimed to quantify and compare the basal and apical rotation and twist of the LV at rest as well as at the peak and recovery stages of DSE in patients with and without coronary artery disease (CAD).
Introduction: Recently introduced microUSB ultrasound probe, which can be connected to personal mobile device constitutes a new class of diagnostic pocket size imaging devices (PSID).The aim of this study was to assess the feasibility and clinical utility of real-time tele-echocardiography with the use such device.
Material And Methods: The study group comprised 30 patients (18 men and 12 women; mean age: 54 ±14 years; mean body mass index: 27 ±6 kg/m), admitted to various hospital departments (infectious diseases, internal medicine and cardiology).
Purpose: To assess the potential ability of two-dimensional speckle tracking analysis (STE) during atrial fibrillation (AF) to identify patients with LA appendage thrombi (LAAT).
Methods: This study involved 93 patients with AF (39% female, 67.1 ± 9.
Aim: To evaluate the impact of the 2 most common bicuspid aortic valve (BAV) morphology patterns [right-left (RL) vs right-noncoronary (RN) cusp fusion] on the aortic diameters and the impact of gender, aortic stenosis (AS), aortic regurgitation (AR), and age on the observed effects.
Methods: The PubMed databases was searched up to December 31, 2016 to identify studies investigating the morphology of BAV and aortic diameters. Inclusion criteria were as follows: the data on diameter of sinuses of Valsalva (SVD) and/or ascending aorta (AAD) and BAV morphology.
Background: General anaesthesia may have negative impact on patient mortality and morbidity, as well as overall procedure costs, in atrial septal occluder (ASO) implantation.
Aim: We sought to evaluate the safety, efficacy, and feasibility of conscious sedation for transcatheter implantation of ASOs.
Methods: A total of 122 patients referred for transcatheter implantation of ASO were included.
Background: Cryoballoon ablation for atrial fibrillation (cryoAF) is relatively simple, cost-effective and easy procedure. However, general anesthesia during this procedure may have negative impact on patients' mortality and morbidity, as well as procedure costs. We sought to assess the feasibility and safety of conscious sedation during cryoAF.
