Normative reference ranges for echocardiographic chamber dimensions in a healthy Central European population: results from the Czech post-MONICA survey

open access: yesCardiovascular Ultrasound, 2019
Background Normative reference values for echocardiographic chamber quantification are of great importance; however, this can be challenging. Our aim was to derive these values including degrees of abnormality from a random Central European population ...

Real-time Assessment of Right and Left Ventricular Volumes and Function in Children Using High Spatiotemporal Resolution Spiral bSSFP with Compressed Sensing [PDF]

open access: yesarXiv, 2018
Background: Real-time (RT) assessment of ventricular volumes and function enables data acquisition during free-breathing. However, in children the requirement for high spatiotemporal resolution requires accelerated imaging techniques. In this study, we implemented a novel RT bSSFP spiral sequence reconstructed using Compressed Sensing (CS) and ...

Management of diastolic heart failure [PDF]

open access: yes, 2010
Diastolic heart failure (HF) is also referred to as HF with preserved left ventricular systolic function. The distinction between systolic and diastolic HFs is a pathophysiological one and isolated forms of left ventricular dysfunction are rarely ...

Left ventricular dysfunction after open repair of simple congenital heart defects in infants and children: Quantitation with the use of a conductance catheter immediately after bypass [PDF]

open access: yes, 1998
Objective: Quantification of myocardial injury after the simplest pediatric operations by load-independent indices of left ventricular function, using conductance and Mikro-Tip pressure catheters (Millar Instruments, Inc., Houston, Tex.) inserted through

Injectable and Sprayable Thermoresponsive Hydrogel with Fouling‐Resistance as an Effective Barrier to Prevent Postoperative Cardiac Adhesions

open access: yesAdvanced Science, EarlyView.
Postoperative cardiac adhesions lead to numerous difficulties in reoperation procedures. Here, a thermo‐responsive in situ formed hydrogel is shown to can reliably cover the wounds after a convenient spraying or injection and significantly reduce adhesion formation in primary and recurrent cardiac injury adhesion models.

Effect of prolonged space flight on cardiac function and dimensions [PDF]

open access: yes
Echocardiographic studies were performed preflight 5 days before launch and on recovery day and 1, 2, 4, 11, 31 and 68 days postflight. From these echocardiograms measurements were made.

Влияние эналаприла малеата и метопролола на ремоделирование и дисфункцию сердца у больных, перенесших q-инфаркт миокарда, при длительном применении [PDF]

open access: yes, 2003
Was study influence long-term (during one year) used ingibitor ACE and β-blocker to heart remodeling, systolic and diastolic function in the 37 patients after myocardial Q-infarction. All patients was separated for 2 groups: first - with EF less 45%, and

Early detection of left ventricular diastolic dysfunction in Chagas' disease [PDF]

open access: yes, 2006
BACKGROUND: Chagas' disease may cause left ventricular diastolic dysfunction and its early detection in asymptomatic patients would allow to stratify the risk and to optimize medical treatment.

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

A novel quantitative indicator of the left ventricular contraction based on volume changes of the left ventricular myocardial segments [PDF]

open access: yesarXiv, 2018
Ejection fraction (EF) is commonly measured by echocardiography, by dividing the volume ejected by the heart (stroke volume) by the volume of the filled heart (end-diastolic volume). Utilizing volume changes of left myocardial segments per a cardiac cycle, physical laws and mathematical equations specific echocardiographic data, this paper serves to ...
