BACKGROUND We examined the relationships of left ventricular (LV) contractile state with LV geometry and hypertrophy in patients with aortic valve disease, and investigated the reversibility of LV hypertrophy and contractility following aortic valve replacement. METHODS Preoperative data from quantitative cineangiography and pressure measurements in 132 patients with chronic aortic valve dise...

BACKGROUND The association of metabolic syndrome (MS) with left ventricular (LV) hypertrophy is controversial. The objective of our study was to investigate the influence of MS on LV mass and geometry in community-based hypertensive patients among Han Chinese. MATERIALS AND METHODS This study included 1733 metabolic syndrome patients according to the International Diabetes Federation (IDF) de...

Left ventricular (LV) hypertrophy is an important predictor of morbidity and mortality in hypertensive patients, and its geometric pattern is a useful determinant of severity and prognosis of heart disease. Studies on LV geometric pattern involving large number of Nigerian hypertensive patients are limited. We examined the LV geometric pattern in hypertensive patients seen in our echocardiograp...

For more than 30 years, the development of concentric left ventricular (LV) hypertrophy in pressure overload was considered adaptive because the parallel deposition of new sarcomeres and the corresponding LV wall thickening succeeded in normalizing LV systolic wall stress despite the high intracavitary systolic pressure. In aortic stenosis, the validity of this paradigm was demonstrated by haem...

AIMS In aortic stenosis (AS), left ventricular (LV) hypertrophy is considered a compensatory response helping maintain systolic function. Recent research in experimental AS suggests, however, that LV hypertrophy is not necessary to sustain LV contractions but may in fact be maladaptive. The present work aimed to clarify the role of LV hypertrophy in AS-related heart failure (HF) in man. METHO...

OBJECTIVES This study examined the relations of echocardiographically determined left ventricular (LV) mass and hypertrophy to the risk of sudden death. BACKGROUND Echocardiographic LV hypertrophy is associated with increased risk for all-cause mortality and cardiovascular disease morbidity and mortality. However, little is known about the association of echocardiographic LV hypertrophy with ...

Pathological cardiac hypertrophy was produced by partial abdominal aortic constriction (PAAC) for 4 wk, while physiological cardiac hypertrophy was produced by chronic swimming training (CST) for 8 wk in rats. Pentoxifylline (30 mg/kg, 300 mg/kg i.p., day) treatment was started three days before PAAC and CST and it was continued for 4 wk in PAAC and 8 wk in CST experimental model. The left vent...

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...

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...

Left ventricular (LV) hypertrophy and concentric remodeling have been defined by using a variety of indexation methods and partition values (PVs) for LV mass and relative wall thickness (RWT). The effects of these methods on the distribution of LV geometric patterns in hypertensive subjects remain unclear. Echocardiograms were obtained in 941 patients with stage I to III hypertension and LV hyp...
