Reactive hyperemia characteristics of the myocardium
American Journal of Physiology-Legacy Content, 1960 Blood flow before and after occlusion of cannulated left circumflex coronary arteries of anesthetized open-chest dogs was studied using a continuously recording rotameter. Five- to one hundred and eighty-second occlusion periods were performed. Flow in excess of control flow (reactive hyperemia), peak flow, and duration of reactive hyperemia increased

Myocardial reactive hyperemia in the newborn
Journal of Surgical Research, 1988 Adenosine may be an important metabolic regulator of coronary blood flow during active hyperemia in the newborn. In this study, the adenosine uptake blocker dipyridamole (DPY) and receptor antagonist theophylline (THEO) were used to assess the role of adenosine in the reactive hyperemic response of the neonatal heart.

Postocclusional Hyperemia for Fractional Flow Reserve After Percutaneous Coronary Intervention
Circulation: Cardiovascular Interventions, 2017 Background— Postocclusional hyperemia caused by balloon occlusion is a potential alternative method of inducing hyperemia for measuring post-percutaneous coronary intervention fractional flow reserve (FFR).

Hyperemia Analysis Software for Assessment of Conjunctival Hyperemia Severity
Current Eye Research, 2018We developed a hyperemia analysis software, which can quantitatively assess the degree of conjunctival hyperemia, and evaluated the reproducibility and reliability of its percent coverage. In addition, we compared the clinical grading and the percent coverage to examine the applicability of the software analysis.We took images of the temporal ...

THE HYPEREMIA AZT AND THE EVALUATION OF THE HYPEREMIA RAT UNIT OF CHORIONIC GONADOTROPIN*
The Journal of Clinical Endocrinology & Metabolism, 1947INTRODUCTION IN an earlier communication (7) we reported the results of 300 rapid pregnancy tests. Infantile female rats, which respond in a few hours to the presence of prolan B (luteinizing hormone—LH) with anterior pituitary reaction (APR) II, served in these tests as the experiment animals. APRII in the rat takes the form of a marked hyperemia, and

Mechanism of Reactive Hyperemia in Limbs of Anesthetized Dogs
American Journal of Physiology, 1965 Reactive hyperemia was studied in the hindlimb and forelimb of 81 anesthetized dogs. Reactive hyperemia volume in response to 5-sec arterial occlusions correlated moderately well with the decrease in intravascular pressure. This correlation was poor for

Reactive Hyperemia vs. Pharmacologic Hyperemia in the Canine Iliac Circulation: A Comparison
Investigative Radiology, 1983Different methods of selective vasodilation have been described. One method is reactive hyperemia, which occurs when an arterial occlusion is released, and another method involves injection of vasodilator drugs. Since both arteriography and pressure measurements are often performed during hyperemia, it is important to know whether these two methods ...
