Coronary Flow and Reserve by Enhanced Transthoracic Doppler Trumps Coronary Anatomy by Computed Tomography in Assessing Coronary Artery Stenosis

Diagnostics, 2021
We report the case of a 71-year-old patient with many risk factors for coronary atherosclerosis, who underwent computed coronary angiography (CTA), in accordance with the guidelines, for recent onset atypical chest pain. CTA revealed critical (>50% lumen

Coronary flow reserve in patients with normal coronary angiograms

Journal 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]

Rheumatology, 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.

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

Journal 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

Early Hyperdynamic Sepsis Alters Coronary Blood Flow Regulation in Porcine Fecal Peritonitis

Frontiers in Physiology, 2021
Background: Sepsis is a common condition known to impair blood flow regulation and microcirculation, which can ultimately lead to organ dysfunction but such contribution of the coronary circulation remains to be clarified.

FFR and Coronary Flow Reserve

JACC: 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),
