Cardiac tamponade in left ventricular dysfunction.
Echocardiographic and hemodynamic data were measured in closed-chest dogs during graded cardiac tamponade (pericardial pressure 5, 10, and 15 mm Hg) before and after production of diffuse ischemic left ventricular dysfunction. Left ventricular dysfunction was produced by intracoronary injection of nonradioactive microspheres (54 +/- 3.9 mm diameter). Changes in left atrial pressure with cardiac...
متن کاملechocardiographic assessment of inappropriate left ventricular mass and left ventricular hypertrophy in patients with diastolic dysfunction
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...
متن کاملEffect of dobutamine on regional diastolic left ventricular asynchrony in patients with left ventricular hypertrophy.
Dobutamine improves systolic as well as diastolic function, but its effect on left ventricular (LV) asynchrony is unknown. An on-line automated segmental motion analysis (A-SMA) system was developed, based on an automatic border detection technique, to evaluate the effect of dobutamine on LV asynchrony in patients with LV hypertrophy (LVH). Low dose (5 microg x kg (-1) x min(-1)) dobutamine str...
متن کاملDiastolic heart failure, diastolic left ventricular dysfunction and exercise intolerance.
The phenomenon of “diastolic heart failure” is rightly receiving greater attention (1–4); community-based studies such as those in Framingham (5) and Olmsted County (6) show that up to 50% of older persons with heart failure do not have impaired left ventricular (LV) systolic function to account for this, and that the condition is usually associated with LV hypertrophy and is preceded by elevat...
متن کاملLeft Ventricular Diastolic Performance
We used first-pass radionuclide angiocardiography to assess filling fraction during the first third of diastole, peak filling rate and peak filling rate during the first third of diastole as indexes of left ventricular diastolic performance at rest and after upright bicycle exercise in 32 normal patients and 68 patients with coronary artery disease. The mean filling fraction was unchanged from ...
