Coronary flow reserve and cardiovascular outcomes: a systematic review and meta-analysis. [PDF]

open access: yesEur Heart J, 2022
Aims This meta-analysis aims to quantify the association of reduced coronary flow with all-cause mortality and major adverse cardiovascular events (MACE) across a broad range of patient groups and pathologies.

Autologous CD34+ Stem Cell Therapy Increases Coronary Flow Reserve and Reduces Angina in Patients With Coronary Microvascular Dysfunction. [PDF]

open access: yesCirc Cardiovasc Interv, 2022
Background: Coronary microvascular dysfunction results in angina and adverse outcomes in patients with evidence of ischemia and nonobstructive coronary artery disease; however, no specific therapy exists.

The Concept of Coronary Flow Reserve

open access: hybridJournal of Cardiovascular Pharmacology, 1992
Coronary reserve has been defined as the ratio of coronary resistance under control (rest) conditions and of coronary resistance after maximal coronary vasodilation. The latter can be achieved by various interventions, the most important and clinically relevant example being intravenous administration of dipyridamole at 0.5 mg/kg of body weight.

Reduced coronary flow reserve in Anderson-Fabry disease measured by transthoracic Doppler echocardiography [PDF]

open access: yesCardiovascular Ultrasound, 2005
Coronary flow reserve was assessed in a patient with Anderson-Fabry disease complicated by symmetric left ventricular hypertrophy. Coronary flow reserve was measurable in all three major coronary arteries providing an opportunity to compare regional ...

Continuous Versus Bolus Thermodilution‐Derived Coronary Flow Reserve and Microvascular Resistance Reserve and Their Association With Angina and Quality of Life in Patients With Angina and Nonobstructive Coronaries: A Head‐to‐Head Comparison [PDF]

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Coronary flow reserve (CFR) and microvascular resistance reserve (MRR) are physiological parameters to assess coronary microvascular dysfunction. CFR and MRR can be assessed using bolus or continuous thermodilution, and the correlation between

AT1 receptors: coronary flow and flow reserve [PDF]

open access: bronzeAmerican 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 ...

Three-Dimensional Angiographic Characteristics versus Functional Stenosis Severity in Fractional and Coronary Flow Reserve Discordance: A DEFINE FLOW Sub Study [PDF]

open access: yesDiagnostics, 2022
Background: Coronary angiography alone is insufficient to identify lesions associated with myocardial ischemia that may benefit from revascularization.

Prior SARS‐CoV‐2 Infection Is Associated With Coronary Vasomotor Dysfunction as Assessed by Coronary Flow Reserve From Cardiac Positron Emission Tomography [PDF]

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Cardiovascular complications from COVID‐19 contribute to its high morbidity and mortality. The effect of COVID‐19 infection on the coronary vasculature is not known.
