The electrocardiogram (ECG) is a relatively insensitive tool for the detection of right ventricular hypertrophy (RVH), but some criteria have high specificity. The recommended ECG screening criteria for RVH are not sufficiently sensitive or specific for screening for mild RVH in adults without clinical cardiovascular disease. The greatest accuracy of the ECG is in congenital heart disease, with intermediate accuracy in acquired heart disease and primary pulmonary hypertension in adults.

Department of Radiology, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Background: Primary hyperparathyroidism (PHPT) is associated with hypertension, left ventricular hypertrophy, and myocardial and valvular calcifications, leading to increased mortality rates. While the association between PHPT and diastolic dysfunction has been well-documented, data on systolic dysfunction and its reversal after curative parathyroidectomy (PTX) remains limited.
Purpose: To evaluate the effect of PTX on cardiovascular parameters, especially systolic dysfunction, in PHPT patients using conventional and speckle-tracking echocardiography (STE).

Aims: How the underlying etiology and pathophysiology of left ventricular (LV) hypertrophy affects LA remodeling and function remains unexplored. The present study aims to investigate the influence of various hypertrophic phenotypes on LA remodeling and function.
Methods And Results: Patients with LV hypertrophy who underwent cardiac magnetic resonance (CMR) were compared to a control group.

This study investigated the sexual dimorphism in right ventricle (RV) remodeling in right heart failure susceptible Fischer CDF rats using the pulmonary artery banding (PAB) model. Echocardiography and hemodynamic measurements were performed in adult male and female Fischer CDF rats at 1- or 2-weeks post-PAB. RV systolic pressure and RV hypertrophy were significantly elevated in PAB rats compared to sham control at 1- and 2-weeks post-PAB; however, no differences were observed between male and female rats.

Extreme prematurity involves a series of complications that a multidisciplinary team should manage. Taking into account the risks related to premature newborns, such as maternal-fetal infections, intrauterine growth restriction, and certain comorbidities associated with young gestational age, our objective is to highlight the importance of a multidisciplinary team in approaching cases with an unfavorable prognosis. This is a case report of an extremely preterm newborn who came from a high-risk pregnancy and needed long-term hospitalization in the Neonatal Intensive Care Unit (NICU) and mechanical ventilation.
