Multiparametric analysis of coronary flow in psoriasis using a coronary flow reserve companion. [PDF]

Eur J Clin Invest, 2022
AbstractBackgroundCoronary microvascular dysfunction (CMD) is usually evaluated measuring coronary flow velocity reserve (CFVR). A more comprehensive analysis of CFVR including additional consideration of the associated logical companion‐CFVR, where hyperemic diastolic coronary flow velocity may act as surrogate, was applied in this study to elucidate ...

Normalization of coronary flow reserve by percutaneous transluminal coronary angioplasty [PDF]

, 1988
Fifteen patients undergoing routine follow-up angiography 5 months after successful percutaneous transluminal coronary angioplasty (PTCA) without angina and with normal exercise thallium scintigraphy were selected for analysis. The coronary flow reserves

Structure (Epicardial Stenosis) and Function (Microvascular Dysfunction) That Influence Coronary Fractional Flow Reserve Estimation

Applied Sciences, 2022
Background. The treatment of coronary stenosis is decided by performing high risk invasive surgery to generate the fractional flow reserve diagnostics index, a ratio of distal to proximal pressures in respect of coronary atherosclerotic plaques.

Fractional Flow Reserve-Guided PCI as Compared with Coronary Bypass Surgery.

New England Journal of Medicine, 2021
BACKGROUND Patients with three-vessel coronary artery disease have been found to have better outcomes with coronary-artery bypass grafting (CABG) than with percutaneous coronary intervention (PCI), but studies in which PCI is guided by measurement of ...
