1.5 and 3 Tesla quantification of myocardial perfusion reserve in comparison to fractional flow reserve [PDF]

Journal of Cardiovascular Magnetic Resonance, 2013
Methods Thirty-four patients referred for coronary x-ray angiography with suspected or known coronary artery disease underwent cardiac magnetic resonance imaging (CMR) at 1.5 and 3 Tesla, and additionally FFR measurement in LAD, CX and RCA. MPR was calculated in 544 myocardial segments at both field strenghts.

Diagnostic efficacy of CCTA and CT-FFR based on risk factors for myocardial ischemia

Journal of Cardiothoracic Surgery, 2022
Background Coronary artery coronary computed tomography angiography (CCTA) can observe the degree of coronary artery stenosis and fractional flow reserve (FFR) can diagnose hemodynamic abnormalities caused by coronary artery stenosis.

Clinical and Vessel Characteristics Associated With Hard Outcomes After PCI and Their Combined Prognostic Implications

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Cardiac death or myocardial infarction still occurs in patients undergoing contemporary percutaneous coronary intervention (PCI). We aimed to identify adverse clinical and vessel characteristics related to hard outcomes after PCI and to ...

Fractional flow reserve in assessment of intermediate non-culprit lesions in acute myocardial infarction [PDF]

Journal of Pharmacy & Pharmacognosy Research, 2023
Context: Percutaneous coronary intervention (PCI) of intermediate non-culprit arteries can reduce death or heart attack risk in patients with acute myocardial infarction and multivessel coronary artery disease.

Automated quantitative analysis of first-pass myocardial perfusion magnetic resonance imaging data [PDF]

arXiv, 2021
Coronary artery disease (CAD) remains the world's leading cause of mortality and the disease burden is continually expanding as the population ages. Recently, the MR-INFORM randomised trial has demonstrated that the management of patients with stable CAD can be guided by stress perfusion cardiovascular magnetic resonance (CMR) imaging and it is non ...

Retracted: Microvascular resistance reserve in the presence of functionally significant epicardial stenosis and changes after revascularization

Physiological Reports, 2023
In the presence of functionally significant epicardial lesions, microvascular resistance reserve (MRR) calculation needs incorporation of collateral flow.

Non-Invasive Flow Ratio (NiFR) Measurement based on Angiography Images [PDF]

Journal of Biomedical Physics and Engineering, 2021
Background: Fractional flow reserve (FFR) is a gold standard to assess the impact of stenosis on the blood flow. The FFR method enhances diagnostic accuracy, lessens the need for stenting, and reduces costs.

Fractional flow reserve after previous myocardial infarction [PDF]

European Heart Journal, 2007
Marques and colleagues have conducted an interesting study on microvascular resistance of viable tissue within an infarcted area. 1 This study is important, not only from a conceptual point of view, but also because it has several relevant implications for the applicability of MIBI spect and fractional flow reserve (FFR) measurement in patients with ...

Fractional Flow Reserve-Based Patient Risk Classification

Diagnostics, 2023
Cardiovascular diseases (CVDs) are a leading cause of death. If not treated in a timely manner, cardiovascular diseases can cause a plethora of major life complications that can include disability and a loss of the ability to work.

Loan and nonloan flows in the Australian interbank network [PDF]

Physica A 391 (2012) 2867-2882, 2012
High-value transactions between Australian banks are settled in the Reserve Bank Information and Transfer System (RITS) administered by the Reserve Bank of Australia. RITS operates on a real-time gross settlement (RTGS) basis and settles payments sourced from the SWIFT, the Austraclear, and the interbank transactions entered directly into RITS. In this
