Hemodynamic and nonhemodynamic factors are implicated in the maintenance and aggravation of left ventricular (LV) hypertrophy in ESRD. Functional consequences of LV geometry are of substantial importance in patients who undergo dialysis and may contribute to explain the negative outcome related to LV hypertrophy, also in patients without overt coronary heart disease (CHD). Whereas most patients...

AIMS We tested the hypothesis that abnormal left ventricular (LV) relaxation is associated with concentric LV geometry. METHODS AND RESULTS Doppler LV filling properties were studied in 1384 hypertensive participants without cardiovascular disease, from the HyperGEN population (731 women, 784 obese, 236 diabetic) and compared in four LV geometry groups; normal, concentric remodelling (3.5%), ...

Fifteen chronically instrumented, conscious dogs were studied to determine whether, in the intact circulation, mechanical interactions dictated by the anatomic contiguity of the two ventricles significantly alter left ventricular (LV) dynamic geometry and systolic function during acute right ventricular (RV) hypertension. The three-dimensional geometry of the left ventricle was monitored with t...

The effect of left ventricular volume (LVV) in relation to the left ventricular mass (LVM) was studied on the voltage electrocardiographic (ECG) criteria of left ventricular hypertrophy (LVH). For this purpose, the sensitivity of numerous voltage criteria were assessed in patients with documented echocardiographic (echo) LVH with or without left ventricular dilatation. The ECG criteria that com...

For over a decade balloon mitral valvuloplasty has been the treatment of choice for severe mitral stenosis and replaced surgical commissurotomy in many selected cases. In spite of this, balloon mitral valvuloplasty has many disadvantages. Such disadvantage might may related to the effect of left ventricular geometry which was proven to be changed in patient with rheumatic mitral stenosis. The A...

OBJECT Subarachnoid hemorrhage (SAH) has been associated with cardiac injury and left ventricular (LV) dysfunction. The incidence and natural history of neurocardiogenic injury after SAH remains poorly understood. The objective of this study was to describe the incidence, time course, recovery rate, and segmental patterns of LV dysfunction after SAH. METHODS Echocardiography was performed thr...

BACKGROUND The various prevalence of LVH and abnormal LV geometry have been reported in different populations. So far, only a few reports are available on the prevalence of LV geometric patterns in a large Chinese untreated hypertensive population. METHODS A total of 9,286 subjects (5167 men and 4119 women) completed the survey and 1641 untreated hypertensive patients (1044 males and 597 fema...

background: echocardiographic evaluations of the longitudinal axis of the left ventricular (lv) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (hfnef). the evaluation of the global and segmental peak systolic longitudinal strains (pslss) by two-dimensional speckle tracking echocardiography (ste) may correlate with conventional echocardiogr...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

we assessed different systolic cardiac indices to detect left and right ventricular systolic dysfunction in cirrhotic patients before liver transplantation. between 2010-2011, 81 consecutive individuals with confirmed hepatic cirrhosis who were a candidate for liver transplantation were enrolled in this study. a total of 32 age and sex matched healthy volunteers were also selected as the contro...
