…information. Coronary pressure measurements permit assessment of the physiological significance of selected stenoses using fractional flow reserve (FFR) and instantaneous wave free ratio (iFR). Other…

…Functional assessment with pressure or flow measurements, intravascular imaging, or fractional flow reserve derived from computed tomography can refine interpretation. Coronary plaque and future events…

…tomographic angiography (CCTA) is a non invasive anatomical examination that depicts the coronary arterial lumen, atherosclerotic plaque, and the severity and distribution of coronary stenosis…

…employed to evaluate myocardial perfusion by measuring the intensity of their uptake within the myocardium. Furthermore, certain radiotracers enable direct measurement of coronary blood flow…

…and have a greater likelihood of coronary artery disease, which is present in approximately 50–60% of patients. Conversely, atrial fibrillation and non cardiac comorbidities…

…arteries are equally compromised, leading to uniform perfusion that may appear deceptively normal on SPECT. Detecting multivessel disease requires quantification of absolute coronary blood flow…

…Definition and pathophysiology Fractional flow reserve (FFR) is an invasive, lesion specific physiological index used to estimate the functional significance of an epicardial coronary stenosis…

Referensvärden Haemodynamic measurements become interpretable only when related to one another. A low blood pressure may be due to low flow, low vascular tone or…
