Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation

open access: yesBrazilian Journal of Otorhinolaryngology, 2022
Introduction: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not

Contribution of Doppler echocardiography to the evaluation of systolic and diastolic function of obese women versus a control group

open access: yesArquivos Brasileiros de Cardiologia, 2001
OBJECTIVE: To study by doppler echocardiography the cardiac systolic and diastolic functions of health, uncomplicated obese subjects. METHODS: Fifty-nine obese women with an average body mass index (BMI) of 35 kg/m² were evaluated and compared with 19 ...

Early and late systolic wall stress differentially relate to myocardial contraction and relaxation in middle-aged adults: the Asklepios study [PDF]

open access: yes, 2013
Experimental studies implicate late systolic load as a determinant of impaired left ventricular (LV) relaxation. We aimed to assess the relationship between the myocardial loading sequence and left ventricular (LV) contraction and relaxation.

Unlocking the Mysteries of Diastolic Function Deciphering the Rosetta Stone 10 Years Later [PDF]

open access: yes, 1929
It has now been a quarter of a century since the first description by Kitabatake and his associates of the use of echo-Doppler to characterize the transmitral flow velocity curves in various disease states.

Types of Diastolic Dysfunction of the Left Ventricle in Adolescents with Myocardial Pathology

open access: yesZdorovʹe Rebenka, 2014
In adolescents with myocardial pathology during isometric tests we detected three types of diastolic dysfunction of the left ventricle (LV) of the heart, depending on E/A ratio.

Development of an efficient mice model of cancer‐associated cardiac cachexia

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This work establishes a preclinical framework for targeting ubiquitin pathways to mitigate the morbidity of cancer‐related cardiopathy. Our integrated approach delineates a hierarchical progression from subcellular dysfunction to macroscopic cardiac deterioration. These findings mechanistically link tumor‐induced cachexia to cardiac dysfunction through

Comparison of echocardiographic parameters of amputee football players with active football players and sedentary individuals

open access: yesBMC Sports Science, Medicine and Rehabilitation, 2023
Background The purpose of this study is to compare the echocardiographic (ECHO) parameters of amputee football players (AF) with those of athletes without a disability (football players) (FP), and sedentary individuals (SI).

Right ventricular global work efficiency: A reliable non‐invasive estimate of right ventricular contractility

open access: yesESC Heart Failure, EarlyView.
The figure illustrates the study design and key findings related to right ventricular myocardial work (RVMW) in heart failure with reduced ejection fraction (HFrEF) patients with and without pulmonary hypertension (PH). Patients were stratified into two groups: those with PH (n = 53) and those without PH (n = 49), as determined by right heart ...

The Invalidity of the Laplace Law for Biological Vessels and of Estimating Elastic Modulus from Total Stress vs. Strain: a New Practical Method [PDF]

open access: yes, 2013
The quantification of the stiffness of tubular biological structures is often obtained, both in vivo and in vitro, as the slope of total transmural hoop stress plotted against hoop strain. Total hoop stress is typically estimated using the "Laplace law."
