Evidence from human and animal models indicate that excessive central sympathetic nerve activity (SNA) plays a pathogenic role in triggering and sustaining hypertension. Thus, treatments targeting this neurogenic (sympathetic) triggered hypertension

Because tracer techniques are gaining an increasing importance for imaging flow (and metabolism) in the heart, experimental evidence is needed on the role of convection and diffusion in the transcoronary transport of solutes. In the present work, the

Our objective was to investigate the properties of [1-(11)C]acetate as a quantitative perfusion tracer for myocardial PET studies.We determined the flow dependence of the effective acetate extraction by a comparison with [(13)N]ammonia in 24 patients

The absence of angiographic findings despite significant coronary artery disease has been previously described. Possible explanations for the limitation of plaque detection by angiography include compensatory vessel enlargement in face of intracorona

Coronary transplant vasculopathy is known to be associated with an early impairment of endothelium-dependent vasodilatation. In this study the largely endothelium-independent dilator response to dipyridamole was evaluated in 22 patients 36 +/- 17 mon

We studied the heterogeneity of myocardial blood flow in nine anesthetized closed-chest dogs using an indicator-dilution technique that allows the stochastic description of transport characteristics for three inert gases (helium, argon, and xenon) fr

To investigate the basis of cardiodepressive side effects in coronary arteriography, the isolated effects of different contrast media on electrolyte levels in blood (and blood fractions) were quantified in vitro. Due to their sodium content and calci

The effects of ventricular pacing (90-330 beats/min) and atrial pacing (120-210 beats/min) on myocardial oxygen consumption (MVO2) and its hemodynamic determinants and on myocardial pumping efficiency were studied systematically on intact dogs. In si

Following single breath inhalations of helium 49 simultaneous inlet-outlet pairs of helium dilution curves were recorded in seven dog experiments from the aortic and coronary sinus blood by use of mass spectrometric technique. After numeric deconvolu
