Breathing maneuvers may elicit a stronger myocardial vascular response than clinical adenosine protocols
Background Adenosine is one of the currently used agents for pharmacological vasodilation protocols used in imaging myocardial perfusion deficits. Yet, its clinical utility is limited by cost, need for i.v. access, and by side effects such as dyspnea and AV block, requiring the presence of a trained physician during administration. Recently, breath holds have been proposed as a potential altern...
متن کامل[Adenosine stress protocols for myocardial perfusion imaging].
BACKGROUND/AIM Treadmill test combined with myocardial perfusion scintigraphy (MPS) is a commonly used technique in the assessment of coronary artery disease. There are many patients, however, who may not be able to undergo treadmill test. Such patients would benefit from pharmacological stress procedures combined with MPS. The most commonly used pharmacological agents for cardiac stress are co...
متن کاملStronger-Than-Quantum Correlations
After an elementary derivation of Bell’ s inequality, classical, quantum mechanical , and stronger-than-quantum correlation functions for 2-particle-systems are discussed. Special functions are investigated which give rise to an extreme violation of Bell’ s inequality by the value of 4. Referring to a specific quantum system it is shown that under certain conditions such an extreme violation wo...
متن کاملHypercoagulability Is a Stronger Risk Factor for Ischaemic Stroke than for Myocardial Infarction: A Systematic Review
BACKGROUND AND PURPOSE Hypercoagulability increases the risk of arterial thrombosis; however, this effect may differ between various manifestations of arterial disease. METHODS In this study, we compared the effect of coagulation factors as measures of hypercoagulability on the risk of ischaemic stroke (IS) and myocardial infarction (MI) by performing a systematic review of the literature. Th...
متن کاملBreathing Maneuvers as a Vasoactive Stimulus for Detecting Inducible Myocardial Ischemia – An Experimental Cardiovascular Magnetic Resonance Study
BACKGROUND Breathing maneuvers can elicit a similar vascular response as vasodilatory agents like adenosine; yet, their potential diagnostic utility in the presence of coronary artery stenosis is unknown. The objective of the study is to investigate if breathing maneuvers can non-invasively detect inducible ischemia in an experimental animal model when the myocardium is imaged with oxygenation-...
