AIMS Less is known about the relation between in-treatment left ventricular (LV) geometry and risk of cardiovascular events. We assessed LV geometric patterns on baseline and annual echocardiograms as time-varying predictors of the primary composite endpoint (cardiovascular death, stroke, and myocardial infarction) in 937 hypertensive patients with LV hypertrophy during 4.8 years losartan- or a...

an elevated pulmonary artery pressure (pap) from any cause is associated with increased mortality, especially in cases of primary pulmonary arterial hypertension (pah). one of the many reasons behind a bad prognosis is the inherent difficulty in assessing right ventricular (rv) function with reproducible methods. intensive research involving the left heart has made it relatively easy to assess ...

Objective: Several studies have shown that Chichorium intybus L. (C. intybus) which possesses flavonoid compounds has an effective role in treatment of cardiovascular diseases. Contractile dysfunction mostly occurs after acute myocardial infarction, cardiac bypass surgery, heart transplantation and coronary angioplasty. The aim of the present study was to investigate the effect of aqueous extra...

AIMS Remodelling of the left ventricle (LV) is associated with adverse cardiovascular events, but the mechanisms of these effects remain undefined. We investigated the relationship of LV mass and geometry to LV function in a large cohort of hypertensive subjects. METHODS AND RESULTS We studied 1074 hypertensive individuals without cardiovascular disease recruited from the London Life Sciences...

The commonly recommended one-dimensional (ID) and two-dimensional (2D) algorithms for left ventricular (LV) mass calculation are limited by assumptions about ventricular geometry and image plane position. To assess the accuracy of these algorithms after eliminating errors associated with image plane position, LV mass was calculated from high quality cardiovascular magnetic resonance imaging (CM...

BACKGROUND Although rarefaction of myocardial angiogenesis has been shown to be associated with left ventricular (LV) systolic dysfunction in animal models of ventricular hypertrophy, this relationship has not been investigated in depth nor validated in humans. We aimed to analyze the relationship of myocardial angiogenesis with various functional and structural ventricular remodeling parameter...

Heart failure constitutes one of the major public health problems with an incidence that approaches 10 per 1000 population after 65 years of age. The majority of clinical trials have focused mostly on left ventricular (LV) failure and have led to established therapeutic approaches that are included in the current guidelines. In contrast, right ventricular (RV) failure is poorly understood and i...

To elucidate left ventricular (LV) cardiac structure and function in patients with mild to moderate essential hypertension, we studied the relationship between LV geometry and function. We evaluated LV diastolic and systolic functions by M-mode echocardiography in 91 age-matched normotensive control subjects (NT) and 124 patients with essential hypertension. Hypertensive patients were divided i...

BACKGROUND The development of clinically applicable fluid-structure interaction (FSI) models of the left heart is inherently challenging when using in vivo cardiovascular magnetic resonance (CMR) data for validation, due to the lack of a well-controlled system where detailed measurements of the ventricular wall motion and flow field are available a priori. The purpose of this study was to (a) d...

OBJECTIVE To describe cardiac tomography findings of an apparently new, presumably congenital, left ventricular (LV) abnormality noted consistently in three patients. PATIENTS Three patients presenting with non-specific symptoms including fatigue, shortness of breath, or chest discomfort were evaluated with cardiac tomography for cardiac structure and function. RESULTS Findings from the thr...
