The venous system contains∾ 70% of the blood volume. The sympathetic nervous system is
by far the most important vasopressor system in the control of venous capacitance. The …

A number of studies have demonstrated considerable plasma volume changes during and
after exposure to different environmental and physiological conditions. These changes are …

BACKGROUND In patients with heart failure, activation of the renin-angiotensin system is
common and has been postulated to provide a stimulus for further left ventricular (LV) …

Objectives. The purpose of this study was to investigate the effect of long-term ventricular
pacing on myocardial perfusion and function in patients receiving such pacing. Background …

BACKGROUND Although recent investigations report the elevation of plasma endothelin
(ET) in congestive heart failure (CHF), it remains unclear if this elevation is that of the …

BACKGROUND Cardiac aging alters many of the acute responses to exercise stress, but the
extent to which chronic exercise (ie, training) can alter or improve the effects of aging in …

] method. The ejection fraction was calculated from a background-corrected left ventricular
count-versus-time curve. The lower limit of normal in our laboratory is 50%. Follow-up data …

Objectives: We sought to evaluate the long-term effects of alternative right ventricular pacing
sites on myocardial function and perfusion. Background: Previous studies have …

Clinical congestive heart failure (CHF) is traditionally associated wtih significant left
ventricular (LV) systolic dysfunction. Over a 1-year period, 58 patients with CHF and intact …
