Are Measures of Left Ventricular Longitudinal Shortening Affected by Left Atrial Enlargement?
Background Even though left atrial (LA) size and function are intimately related to left ventricular (LV) diastolic dysfunction, the role of LA with regard to LV systolic function is less clear. Consequently, we examined the potential association that might exist between measures of longitudinal LV systolic shortening and LA dilation using LA volume index (LAVI). Methods In this retrospective...
متن کاملEffect on obstruction on longitudinal left ventricular shortening in hypertrophic cardiomyopathy.
OBJECTIVES We investigated the cause of the midsystolic drop (MSD) in left ventricular (LV) ejection velocities that are observed with hypertrophic cardiomyopathy (HCM) and severe obstruction. BACKGROUND Dynamic obstruction is an important determinant of symptoms and adverse outcome. The MSD in velocity and flow occurs in patients with gradients >60 mm Hg. The nadir velocity in the LV occurs ...
متن کاملLeft ventricular longitudinal strain in soccer referees
Along the years, the analysis of soccer referees perfomance has interested the experts and we can find several types of studies in literature using in particular cardiac imaging. The aim of this retrospective study was to observe relationship between VO2max uptake and some conventional and not-conventional echocardiographic parameters. In order to perform this evaluation, we have enrolled 20 re...
متن کاملHypertension and left ventricular hypertrophy.
In response to high blood pressure, left ventricular hypertrophy develops. But in hypertension, the myocardial hypertrophied structure is abnormal. The prevalence of this hypertrophy is influenced by age, gender, weight, race, genetics and the severity of high blood pressure. By echocardiography, it has been possible to detect non invasively and more precisely this hypertrophy and its anatomica...
متن کاملLeft ventricular remodeling with exercise in hypertension.
We investigated how exercise training superimposed on chronic hypertension impacted left ventricular remodeling. Cardiomyocyte hypertrophy, apoptosis, and proliferation in hearts from female spontaneously hypertensive rats (SHRs) were examined. Four-month-old SHR animals were placed into a sedentary group (SHR-SED; n = 18) or a treadmill running group (SHR-TRD, 20 m/min, 1 h/day, 5 days/wk, 12 ...
