Ultrasound-based estimation of arterial wall elasticity is commonly used to assess arterial stiffness. However, previous elastography studies have mostly addressed radial strain measurements, and the longitudinal strain has been more or less ignored. This study shows the feasibility of a speckle-tracking-based algorithm for simultaneous estimation of radial and longitudinal strain in the carotid artery in silico. Additionally, these results were preliminarily confirmed in vivo.

Aim The study aimed to detect subtle left ventricular (LV) systolic dysfunction, reflected by abnormal global longitudinal strain (GLS), in patients with stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) and to evaluate any improvement in GLS at 24 hours and six months post-PCI. Methods A total of 94 patients with stable CAD scheduled for elective PCI at our hospital were evaluated using conventional 2D echocardiography and GLS prior to the procedure. Follow-up assessments were conducted at 24 hours and six months post-PCI.

Background: Cardiac amyloidosis (CA) is a challenging diagnosis, particularly when the classic signs, such as increased wall thickness in a non-dilated left ventricle (LV), are absent. This makes the diagnosis more difficult in patients with normal LV wall thickness. We present a case of CA without increased wall thickness and without the characteristic granular sparkling echotexture in a non-dilated LV.

Right ventricular (RV) longitudinal strain has emerged as a crucial tool for evaluating RV systolic function in patients with heart disease. The complex anatomy of the RV presents challenges for functional assessment, traditionally conducted using conventional parameters, such as tricuspid annular plane systolic excursion and RV fractional area change. While these conventional methods are simple and practical, they have limitations in reflecting the majority of global RV systolic function.

Myocyte disarray and fibrosis are underlying pathologies of hypertrophic cardiomyopathy (HCM) caused by genetic mutations. However, the extent of their contributions has not been extensively evaluated. In this study, we investigated the effects of genetic mutations on myofiber function and fibrosis patterns in HCM.

Background: Although anthracycline-related cardiotoxicity is widely studied, only a limited number of echocardiographic studies have assessed cardiac function in breast cancer survivors (BCSs) beyond ten years from anthracycline treatment, and the knowledge of long-term cardiorespiratory fitness (CRF) in this population is scarce. This study aimed to compare CRF assessed as peak oxygen uptake (V̇O), cardiac morphology and function, and cardiovascular (CV) risk factors between long-term BCSs treated with anthracyclines and controls with no history of cancer.
Methods: The CAUSE (Cardiovascular Survivors Exercise) trial included 140 BCSs recruited through the Cancer Registry of Norway, who were diagnosed with breast cancer stage II to III between 2008 and 2012 and had received treatment with epirubicin, and 69 similarly aged activity level-matched controls.
