Coronary Vasodilator Reserve After Human Orthotopic Cardiac
Cardiac transplantation is frequently associated with accelerated coronary atherosclerosis and immune-mediated microvascular injury. To determine if orthotopic cardiac transplantation impairs the capacity of the coronary vasculature to vasodilate and conduct hyperemic blood flow, maximal coronary vasodilator reserve was measured in 25 cardiac allograft recipients with no evidence of rejection 6...

متن کاملCoronary vasodilator reserve in ischemic myocardium of the exercising dog.
BACKGROUND Previous work has reported that coronary vasodilator reserve may persist in myocardium rendered ischemic by hypoperfusion. This study investigated the presence and extent of residual coronary vasomotor tone in myocardial regions made acutely ischemic by a flow-limiting coronary stenosis during exercise. METHODS AND RESULTS Studies were done in chronically instrumented dogs undergoi...
متن کاملEvidence of abnormal vasodilator reserve in coronary spasm.
A 60-year-old man was referred for cardiac catheterization because of increasingly frequent episodes of chest pain occurring mainly at rest but also with exertion. He had a history of mild systemic hypertension and esophagitis due to gastroesophageal reflux. A treadmill test performed shortly after the onset of his symptoms 3 years earlier was negative at a pressure rate product of 264 X IO2 mm...
متن کاملVasodilator reserve: a functional assessment of coronary health.
Assessment of coronary artery stenosis severity depends on either determination of the anatomic dimensions of the stenosis by angiographic techniques or assessment of the functional significance of the stenosis by measurement of its effect on blood flow. Measurement of myocardial blood flow during maximal pharmacological vasodilation (vasodilator reserve) has been used to examine the functional...
