…therefore potentially suitable for a selective invasive approach? Is the clinical likelihood of true NSTE ACS low enough that non invasive evaluation is more appropriate…

Cardiology Myocardial ischemia and infarction Definition and pathophysiology Fractional flow reserve (FFR) is an invasive, lesion specific physiological index used to estimate the functional significance…

…symptoms, findings from non invasive testing and the anticipated effect of the result on management. ICA with available coronary pressure assessment is recommended in patients…

Cardiology Principles of myocardial perfusion imaging Myocardial perfusion imaging (MPI) is a non invasive technique for detecting and quantifying coronary artery disease (CAD). It offers…

…Coronary artery calcium (CAC) scoring is a non invasive method for detecting and quantifying calcified coronary atherosclerotic plaque. It is performed using a non contrast…

…diagnosis depends on functional assessment. Coronary microvascular dysfunction (CMD) is characterized invasively by reduced CFR and increased microvascular resistance, measured by the index of microcirculatory…

…Myocardial ischemia and infarction Definition and Clinical Role Coronary computed tomographic angiography (CCTA) is a non invasive anatomical examination that depicts the coronary arterial lumen…

…a substantial minority of intermediate lesions. Over the past three decades, invasive physiological indices, led by fractional flow reserve (FFR), have been validated against outcomes…
