  • vessel
  • The heart was cooled, and contrast medium (CM) consisting of distilled water heated to 40 °C was injected in a coronary vessel, while thermal images were captured. (springer.com)
  • Large vessel resistance was calculated as the pressure gradient along the vessel segment divided by the coronary flow. (ovid.com)
  • however, the relative increase in the resistance of the large vessel was only about 60% of that seen for the entire coronary bed. (ovid.com)
  • acute
  • Shiina et al conclude that despite these limitations, their results "suggest that cacao flavonoid has acute positive effects on coronary circulation. (innateresponse.com)
  • At the moment, however, the pathophysiological role of TFPI in human atherothrombotic disorders such as acute coronary syndromes (ACS) is still largely unknown. (ahajournals.org)
  • perfusion
  • Adenosine-induced hyperemia decreases the diastolic perfusion gradient, increasing shunting by the fistulae and hence causing a coronary steal phenomenon. (ahajournals.org)
  • patients
  • OBJECTIVE To determine whether increased plasma concentrations of endothelin-1 (ET-1) and big endothelin (BET) play a role in the regulation of coronary circulation in patients with idiopathic dilated cardiomyopathy (IDCM). (bmj.com)
  • CONCLUSIONS The coronary circulation in patients with IDCM is exposed to an increased endothelin load. (bmj.com)
  • Experience with 35 attempts in 31 patients at such coronary opacification is described. (ahajournals.org)
  • Coverage of coronary CT in the lay press and aggressive marketing of CT imaging technology to cardiologists and patients only serves to increase tension. (ahajournals.org)
  • diameter
  • Researchers note possible limitations of this study include the absence of coronary flow volume and diameter measurements (coronary flow velocity was assessed), the short study period of two weeks (the long-term effects and increased amounts of cacao flavonoids remain unexamined) and the study population included only healthy male subjects. (innateresponse.com)
  • 1)Developement of New soft X ray TV system for measuring internal diameter of coronary artery. (nii.ac.jp)
  • cardiology
  • The arrival of coronary CT has opened a new front in the seemingly perpetual to and fro between the cardiology and radiology camps, with battles now being fought at the state and national regulatory levels. (ahajournals.org)
  • cardiovascular
  • In contrast, cardiovascular MRI (CMR), which has the potential to provide a comprehensive functional examination including coronary imaging, is more demanding at the image-acquisition stage. (ahajournals.org)
  • plaque
  • Coronary thrombosis generally occurs at the site of a preexisting atherosclerotic plaque, usually triggered by fissuring or ulceration of the plaque. (ahajournals.org)
  • measurements
  • This will also be done to provide the Flowlab construction with appropriate measurements for the coronary simulation pipe, and input data for its final design. (diva-portal.org)
