Measurement of myocardial fractional flow reserve during coronary angioplasty in patients with old myocardial infarction

Catheterization and Cardiovascular Diagnosis, 1997
Although myocardial fractional flow reserve (FFRmyo) has been demonstrated to be a useful index for determining functional significance of coronary stenosis, the data in previous studies was derived from a highly selected group of patients. The aim of this study was to investigate the value of FFRmyo in a more clinically relevant group of patients ...

Prognostic Role of Myocardial Flow Reserve in Heart Failure With Preserved Ejection Fraction

Kardiologiia, 2023
Aim      To study the role of myocardial blood flow (MBF) and myocardial flow reserve (MFR) in patients with heart failure with preserved ejection fraction (HFpEF) in stratifying the risk of HFpEF progression during 12 months of follow-up.Material and methods  The study included 58 patients with non-obstructive coronary artery disease and HFpEF ...

Interpretation of fractional flow reserve in ST-elevation myocardial infarction culprit lesions

Coronary Artery Disease, 2015
Pressure wire assessment of the infarct-related artery (IRA) in ST-elevation myocardial infarction (STEMI) is not recommended until microcirculatory dysfunction recovers.The objective of this study was to assess serial fractional flow reserve (FFR) and the index of microcirculatory resistance (IMR) in the IRA of STEMI patients to better understand and ...

Impact of myocardial supply area on the transstenotic hemodynamics as determined by fractional flow reserve

Catheterization and Cardiovascular Interventions, 2013
ObjectivesThe aim of this study was to investigate the impact of myocardial area supplied by the coronary artery on fractional flow reserve (FFR).BackgroundVarious factors other than the degree of epicardial stenosis influence the physiological significance of a coronary artery stenosis.MethodsA total of 296 coronary lesions in 217 patients were ...
