Left ventricular hypertrophy has been suggested to mediate the relation between hypertension and left atrial enlargement, with associated risks of atrial fibrillation and stroke. However, less is known about correlates of left atrial size in hypertensive patients with left ventricular hypertrophy. We assessed left atrial size by echocardiography in 941 hypertensive patients, age 55 to 80 (mean,...

BACKGROUND Left ventricular hypertrophy is influenced by both hemodynamic and non-hemodynamic factors. Ambulatory blood pressure is correlated with left ventricular hypertrophy. We established the influences of hemodynamic and non-hemodynamic factors, including ambulatory blood pressure, on variation in left ventricular mass in healthy Korean adults. METHOD We included 172 subjects (male = 71...

INTRODUCTION Left ventricular hypertrophy and diastolic dysfunction in children and adolescents with essential hypertension tend to be underdiagnosed. The aims of this study were to investigate left ventricular hypertrophy and diastolic dysfunction in the subjects with essential hypertension defined by ambulatory blood pressure monitoring. METHODS A total of 38 Korean subjects aged 9-19 years...

OBJECTIVE To determine to what extent inaccuracies in measuring the end diastolic diameter of the left ventricle, the interventricular septum, and the posterior wall, by M mode echocardiography influence the left ventricular mass calculated by the Devereux's formula. DESIGN Mathematical model. RESULTS Relatively small measurement inaccuracies such as 5%, which are known to be inherent in th...

BACKGROUND Patients suffering from major beta thalassemia need frequent blood transfusions and, if not treated well, would be at risk of heart dysfunction. This study was performed to determine the diagnostic value of electrocardiography versus echocardiography in measuring the left ventricular mass index in these patients. METHODS Between July 2010 and June 2011, 82 asymptomatic patients ove...

Although recent studies have suggested that blacks compared with whites have an increased prevalence of left ventricular hypertrophy, it remains uncertain whether this is true despite adjustment for body composition (fat mass and fat-free mass) and when assessed by cardiac MRI in the general population. The Dallas Heart Study is a population-based study of Dallas County in which 1335 black and ...

OBJECTIVE To examine how fetal and infant growth are related to left ventricular mass in adult life. DESIGN A follow up study of men born during 1920-30 whose birth weights and weights at 1 year were recorded. SETTING Hertfordshire, England. SUBJECTS 290 men born and still living in East Hertfordshire, England. MAIN OUTCOME MEASURE Left ventricular mass calculated from measurements of i...

Because of its simplicity, widespread availability, relatively low cost, and lack of adverse effects, M-mode echocardiography has become the most widely used technique for measurement of human left ventricular mass. Necropsy comparison studies have yielded formulas for anatomically accurate estimation of left ventricular mass in patients with normally shaped ventricles using left ventricular me...
