Subclinical left ventricular systolic dysfunction in patients with severe aortic stenosis: A speckle-tracking echocardiography study.
OBJECTIVE In patients with aortic stenosis (AS), the left ventricular (LV) geometry changes due to the increased LV afterload. However, subclinical myocardial dysfunction can develop despite a normal LV ejection fraction (EF). This study was an investigation of subclinical LV systolic dysfunction in patients with severe AS with a normal LV EF using a strain imaging method, speckle-tracking echo...
متن کاملSubclinical left ventricular systolic dysfunction in patients with metabolic syndrome: A case-control study using two-dimensional speckle tracking echocardiography
BACKGROUND The dramatic increase in the prevalence of metabolic syndrome is associated with more increased cardiovascular morbidity and mortality in this group. Some recent studies suggested that metabolic syndrome is associated with increased risk of subclinical left ventricular (LV) systolic dysfunction. In the present cross-sectional case-control study, the utility of two-dimensional speckle...
متن کاملSubclinical left ventricular dysfunction in preeclamptic women with preserved left ventricular ejection fraction: a 2D speckle-tracking imaging study.
BACKGROUND Patients with preeclampsia are at risk for cardiovascular disease. Changes in cardiac function are subtle in preeclampsia and are difficult to quantify with conventional imaging. Strain measurements using speckle-tracking echocardiography have been used to sensitively quantify abnormalities in other disease settings. METHODS AND RESULTS We evaluated the feasibility and sensitivity ...
متن کاملEvaluation of Subclinical Left Ventricular Systolic Dysfunction in Chronic Asymptomatic Alcoholics by Speckle Tracking Echocardiography
By using two-dimensional speckle tracking echocardiography, we aimed to investigate the structural and functional changes on myocardium in chronic asymptomatic alcoholics without any cardiovascular disease. Forty-one consecutive asymptomatic male alcoholics who were admitted to the outpatient alcoholism unit and 30 age matched healthy male volunteers selected as the control group were enrolled ...
متن کاملEvaluation of subclinical left ventricular systolic dysfunction using two-dimensional speckle-tracking echocardiography in patients with non-alcoholic cirrhosis.
INTRODUCTION Cirrhosis is associated with certain abnormalities in left ventricular (LV) structure and function. Two-dimensional speckle-tracking echocardiography (2D-STE) enables a rapid and accurate analysis of regional LV systolic mechanics in the longitudinal, radial and circumferential directions. The aim of this study was to precisely assess the differences among the 3 directions in the e...
