Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]
Computer Methods and Programs in Biomedicine, 175: 95-102, 2019, 2019 Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear. Aim of the present work is to computationally explore whether and to what extent ventricular rate during AF affects the ...

The coronary circulation in acute myocardial ischaemia/reperfusion injury: a target for cardioprotection. [PDF]
Cardiovasc Res, 2019 The coronary circulation is both culprit and victim of acute myocardial infarction. The rupture of an epicardial atherosclerotic plaque with superimposed thrombosis causes coronary occlusion, and this occlusion must be removed to induce reperfusion ...

A patient-specific lumped-parameter model of coronary circulation. [PDF]
Sci Rep, 2018 A new lumped-parameter model for coronary hemodynamics is developed. This model is developed for the whole coronary network based on CT scans of a patient-specific geometry including the right coronary tree, which is absent in many previous mathematical ...

Wave intensity analysis and its application to the coronary circulation. [PDF]
Glob Cardiol Sci Pract, 2017 Wave intensity analysis (WIA) is a technique developed from the field of gas dynamics that is now being applied to assess cardiovascular physiology. It allows quantification of the forces acting to alter flow and pressure within a fluid system, and as ...

The Coronary Circulation as a Target of Cardioprotection [PDF]
Circulation Research, 2016 The atherosclerotic coronary vasculature is not only the culprit but also a victim of myocardial ischemia/reperfusion injury. Manifestations of such injury are increased vascular permeability and edema, endothelial dysfunction and impaired vasomotion, microembolization of atherothrombotic debris, stasis with intravascular cell aggregates, and finally ...

THE ACTION OF THE NITRITES ON THE CORONARY CIRCULATION [PDF]
Archives of Internal Medicine, 1921 The nitrites have been employed in the treatment of angina pectoris since the time of Lauder Brunton, and it is well known that in many instances the pain subsides soon after the administration of a pearl of amyl nitrite or a pellet of nitroglycerin.
