Bimodal Pattern of Coronary Microvascular Involvement in Diabetes Mellitus
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundThe contribution of functionally disturbed coronary autoregulation and structurally impaired microvascular vasodilatory function to reduced coronary flow velocity reserve, reflecting impaired coronary microcirculation in diabetes mellitus (DM),

Modern scintigraphic methods for assessing myocardial blood flow and reserve
Бюллетень сибирской медицины, 2021 Background. Today, myocardial perfusion scintigraphy is an informative and accessible method for evaluating ischemic changes in the heart. However, this method has limitations, which are more connected with a semiquantitative assessment of the study ...

Collateral donor artery physiology and the influence of a chronic total occlusion on fractional flow reserve [PDF]
, 2015 Background— The presence of a concomitant chronic total coronary occlusion (CTO) and a large collateral contribution might alter the fractional flow reserve (FFR) of an interrogated vessel, rendering the FFR unreliable at predicting ischemia should the ...

AT1 receptors: coronary flow and flow reserve [PDF]
American Journal of Hypertension, 2000 Angiotensin II, through its effects at the angiotensin-type 1 receptor, elevates arterial pressure and exacerbates hypertensive heart disease. Alterations in coronary hemodynamics, including reductions in coronary blood flow and flow reserve promotes coronary insufficiency and contributes to the increased cardiovascular risk associated with these ...

Abnormal Myocardial Blood Flow Reserve Observed in Cardiac Amyloidosis [PDF]
, 2016 We performed real-time myocardial contrast echocardiography on a patient with cardiac amyloidosis and previous normal coronary angiography presenting with atypical chest pain to assess myocardial blood flow reserve (MBFR).

Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]
, 2017 Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

FFR post-PCI: what we learned from the FFR-SEARCH study
REC: Interventional Cardiology (English Ed.), 2021 WHAT DO WE KNOW ABOUT FRACTIONAL FLOW RESERVE AFTER STENTING? The introduction of the concept of fractional flow reserve (FFR) in the mid 90s moved coronary physiology from experimental science to routine use at the cath lab.1-3 Added to the better ...

Stable coronary syndromes: pathophysiology, diagnostic advances and therapeutic need [PDF]
, 2018 The diagnostic management of patients with angina pectoris typically centres on the detection of obstructive epicardial CAD, which aligns with evidence-based treatment options that include medical therapy and myocardial revascularisation.
