Coronary Microcirculation Downstream Non‐Infarct‐Related Arteries in the Subacute Phase of Myocardial Infarction: Implications for Physiology‐Guided Revascularization

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Concerns exist about reliability of pressure‐wire‐guided coronary revascularization of non‐infarct‐related arteries (non‐IRA). We investigated whether physiological assessment of non‐IRA during the subacute phase of myocardial infarction might

Angiogenic CD34 Stem Cell Therapy in Coronary Microvascular Repair—A Systematic Review

open access: yesCells, 2021
Ischemia with non-obstructive coronary arteries (INOCA) is an increasingly recognized disease, with a prevalence of 3 to 4 million individuals, and is associated with a higher risk of morbidity, mortality, and a worse quality of life.

Coronary flow reserve in patients with normal coronary angiograms

open access: yesJournal of the American College of Cardiology, 1985
It has been estimated that 20% of patients who undergo coronary angiography for the evaluation of chest pain have angiographically normal coronary vessels with no other car• diac cause for their discomfort. Although the natural history of this patient group is favorable (1-3), the mechanisms responsible for the pain frequently remain mysterious. In the

Blunted coronary flow reserve in systemic sclerosis [PDF]

open access: yesRheumatology, 2004
We investigated whether the non-invasive determination of coronary flow reserve (CFR), as evaluated by transthoracic Doppler echocardiography, might be a potential method to detect early dysfunction of cardiovascular system in patients affected by systemic sclerosis (SSc) without clinical signs or symptoms of cardiac impairment.

FFR and Coronary Flow Reserve

open access: yesJACC: Cardiovascular Imaging, 2012
The FAME (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation) study has re-emphasized the importance of assessing functional consequences of coronary stenoses ([1,2][1]). In that multicenter trial involving 1,005 patients with multivessel coronary artery disease (CAD),

Using QCM‐D for Real‐Time Analysis of Cell Adhesion Dynamics at Biointerfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores adhesion of human fibroblasts to functionalized biomaterial surfaces. Quartz crystal microbalance with dissipation (QCM‐D) is used to measure cell responses in real time. The QCM‐D signalis correlated with changes in cell morphology and focal adhesion kinase (FAK) activation. This data shows a positive correlation between the energy
