Kurashiki City, Japan - Coronary flow reserve (CFR) can be assessed by pressure measurement as well as by the more conventional flow- or velocity-derived methods, according to a study reported in the ...

A head-to-head comparative study of multiple imaging modalities suggests that positron emission tomography (PET) is the most accurate noninvasive test for the detection of myocardial ischemia. In a ...

A thrombus is an important component of the active and unstable atherosclerotic coronary plaque. A thrombus exhibits unique physical properties and commonly displays profound abnormal vascular ...

Exercise electrocardiographic (ECG) stress tests appeared to reliably indicate that some patients with angina with nonobstructive coronary arteries (ANOCA) actually had coronary microvascular ...
