Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging [PDF]

Global Cardiology Science & Practice, 2012
Objectives: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Assessment of left atrial function by volumetric indices and tissue Doppler imaging in ischaemic and idiopathic dilated cardiomyopathy

The Egyptian Heart Journal, 2014
Left atrial (LA) contractility plays an important role in maintenance of cardiac output in patients with left ventricular systolic dysfunction. Although left atrial contractile dysfunction has been reported in dilated cardiomyopathy of ischemic and non ...

Left atrial size and contractile function in healthy dogs and dogs with chronic mitral valve disease

Pesquisa Veterinária Brasileira
: In humans, left atrial enlargement and reduced contractile functions are associated with adverse cardiovascular events and a poor prognosis in many dilatation of the left atrium occurs with the gradual evolution of chronic mitral valve disease and is ...

Left atrial function: evaluation by strain analysis [PDF]

Cardiovascular Diagnosis and Therapy, 2018
The left atrium has an important role in modulating left ventricular filling and is an important biomarker of cardiovascular disease and adverse cardiovascular outcomes. While previously left atrial (LA) size was utilised, the role of LA function as a biomarker is increasingly being evaluated, both independently and also in combination with LA size ...

The Impact of Atrial Fibrillation on All Heart Chambers Remodeling and Function in Patients with Dilated Cardiomyopathy—A Two- and Three-Dimensional Echocardiography Study

Life, 2023
Atrial fibrillation is frequently seen in patients with dilated cardiomyopathy (DCM), and its presence impacts the function of the heart, with clinical and prognostic consequences. In this prospective single-center study, we aimed to assess the impact of

Left Atrial Appendage Function and Stroke Risk [PDF]

Stroke, 2015
About 30% to 40% of ischemic stroke is of unknown cause.1,2 Recently, biomarkers of atrial dysfunction, or atrial cardiopathy, have been associated with embolic stroke risk even in the absence of atrial fibrillation (AF), suggesting that the presence of AF is not required for left atrial thromboembolism to occur.3 Most left atrial thrombi occur in the ...

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Left Atrial Function in Diastolic Heart Failure [PDF]

Circulation: Cardiovascular Imaging, 2009
Background— Abnormalities in left ventricular (LV) structure and function occur in patients with diastolic heart failure (DHF). The reasons for the transition from asymptomatic dysfunction to heart failure need better definition, including noninvasive measurements that can detect the transition.
