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-1) 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 ve...

background: the association of metabolic syndrome (ms) with left  ventricular (lv) hypertrophy is controversial. the objective of our study was to investigate the infl uence 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) d...

Objective(s): To determine the effects of triiodothyronine (T3) intracoronary perfusion in isolated hearts and short-term administration in rats on the left ventricular (LV) phosphorylation patterns of Akt and ERK1/2. Materials and Methods: Cardiodynamic and hemodynamic parameters were evaluated in Langendorff–perfused hearts. Left ventr...

s S55 Eur J Echocardiography Abstracts Supplement, December 2006 analysed by 2 separate observers. TOE and RT-3DE images were acquired digitally on the Phillips IE33 ultrasound machine and stored for off line analysis. The RT-3DE datasets were analysed with Phillips Qlab software (version 4.0). Leaflet segments and commissures were displayed in short axis en-face and long axis views. Echocardio...

BACKGROUND Ventricular hypertrophy begins as a physiological adaptation to cardiac overload but progresses to a pathological state. We examined whether the extent of hypertrophy influenced the response to exercise in terms of its effects on regional and global ventricular function and transmural myocardial blood flow distribution. METHODS AND RESULTS Left ventricular (LV) hypertrophy was indu...

Pressure overload left ventricular (LV) hypertrophy was produced by banding the ascending aorta of puppies and allowing them to grow to adulthood. LV free wall weight per body weight increased by 87% from a normal value of 3.23 +/- 0.19 g/kg. Hemodynamic studies of conscious dogs with LV hypertrophy and of normal, conscious dogs without LV hypertrophy showed similar base-line values for mean ar...

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

BACKGROUND Echocardiography provides a noninvasive means of assessing left ventricular (LV) structure and evidence of LV wall remodeling in hypertensive persons. The relation of demographic, biological, and other factors with LV structure can be assessed. METHODS AND RESULTS LV structure was assessed by M-mode echocardiograms for 511 men and 333 women with mild hypertension (average blood pre...

BACKGROUND Several reports have suggested that plasma B-type natriuretic peptide (BNP) levels are elevated in hypertensive patients especially with left ventricular (LV) hypertrophy. However, few data have been available concerning the utility of plasma BNP measurement to identify LV hypertrophy in hypertensive patients in a general population screening context. METHODS We measured plasma BNP...

The relationship between casual blood pressure and left ventricular (LV) mass has been reported to be fairly weak in hypertensive patients. In this study we analyzed this relationship using noninvasive devices to monitor blood pressure for 24 hours in ambulatory patients and M-mode echocardiography to determine LV mass. Among the 33 patients with hypertension, 21 had echocardiographic LV hypert...
