Various coronary physiological measurements can be made in the cardiac catheterization
laboratory using sensor-tipped guidewires; they include the measurement of poststenotic …

Measurements of coronary flow reserve, once used only for research, have gained wide
acceptance as an additional diagnostic approach in the decision-making process of …

BACKGROUND Controversy exists regarding the ability of intra-aortic balloon pumping to
increase coronary blood flow in patients with obstructive coronary artery disease. To assess …

Background The aim of this prospective, multicenter study was the identification of Doppler
flow velocity measurements predictive of clinical outcome of patients undergoing single …

Objectives. The aim of this study was to assess coronary blood flow during intraaortic
balloon counterpulsation by direct measurement. Background. In a majority of human …

Distal coronary flow velocity measurements were previously limited to open heart or
experimental procedures. Unlike previous Doppler catheter techniques, a Doppler …

Objectives. This study was designed to assess whether the spectral waveform of coronary
velocity on Doppler study is characteristically altered in the presence of significant stenosis …

Background—AMI reperfusion by thrombolysis does not improve TIMI flow and LV function.
The role of infarct-related artery (IRA) stenosis and superimposed changes in coronary …

Objectives. The aim of this study was to use Doppler catheterization and sequential dynamic
positron emission tomography (PET) to investigate the role and time course of abnormal …

Background The aim of this study was to investigate both endothelium-dependent and
endothelium-independent vasodilatation in syndrome X patients. Recently selective …
