We studied reactive hyperemia in a group of patients with heart failure before and after therapy, since changes in the characteristics of muscular blood flow may influence the functional class of these patients. At the same time we evaluated some echocardiographic parameters too. When the patients improved clinically, they showed an increase in muscular blood flow at rest and in percent of fractional shortening and a decrease in peripheral vascular resistance. The reactive hyperemia did not change significantly. This fact probably depends on a maximal response to the postischemic hyperemia and represents the integrity of autoregulatory mechanisms.

    The best-fit method was applied to data of calf basal resting and reactive hyperemia blood flow, recorded at 4-hr, intervals during a day in 15 patients with intermittent claudication. The mathematical-statistical analysis suggests existence of a circadian rhythm of calf blood flow, which has...

    Background: Biventricular pacing is a new therapy for the treatment of heart failure. However, a substantial number of patients do not respond to this therapy. Hypothesis: Individually determined maximal pacing sites will improve the haemodynamic response and increase the number of responders....

    Abstract Background  The pathogenesis of normal tension glaucoma (NTG) might be related to impaired autoregulation of ocular blood flow. The purpose of the study is to evaluate retinal haemodynamics by fluorescein angiography and to correlate arteriovenous passage times (AVP) with ocular...
