Management in unstable angina [PDF]

Postgraduate Medical Journal, 1988
That unstable angina is a serious and potentially dangerous condition which requires immediate attention is a statement with which few clinicians would disagree. However, if it is examined more closely and attempts are made to establish exactly just how serious and how dangerous, an apparent confusion emerges.

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Reduced plasma adiponectin levels relative to oxidized low density lipoprotein and nitric oxide in coronary artery disease patients

Clinics, 2011
INTRODUCTION: Adiponectin is a circulating hormone that is produced exclusively by adipocytes and has antiinflammatory and anti-atherogenic properties. The hypothesis that there are differences in adiponectin levels between stable and unstable coronary ...

Temporal Trends and Prognosis in Rotational Atherectomy: A Comparison of Contemporary and Traditional Eras

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Rotational atherectomy (RA) has undergone considerable technical modernization in recent years. This study evaluated whether RA performed in the contemporary era was associated with superior cardiovascular outcomes compared with the traditional era. Aims To compare the clinical characteristics and cardiovascular outcomes of patients

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Recent studies have questioned whether iodinated contrast is causally related to acute kidney injury (AKI). AIM We pursed a contemporary analysis to determine the impact of contrast dose on AKI following coronary procedures in an era of lower contrast doses and less nephrotoxic agents.

Angiographie morphology and the pathogenesis of unstable angina pectoris [PDF]

, 1985
In 110 patients with either stable or unstable angina, the morphology of coronary artery lesions was qualitatively assessed at angiography. Each obstruction reducing the luminal diameter of the vessel by 50% or greater was categorized into one of the ...

Incidence of Periprocedural Myocardial Injury and Infarction After Intravascular Lithotripsy for Calcified Coronary Artery Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) has emerged as an effective technique for modifying heavily calcified coronary plaques, facilitating optimal stent expansion while minimizing procedural complications. However, data on periprocedural myocardial injury (PMI) and infarction (PPMI) following IVL remain scarce.

Circulating platelet products in unstable angina pectoris.

, 1981
In 19 patients with unstable angina pectoris at rest, plasma levels of the platelet-derived proteins beta-thromboglobulin and platelet factor 4 were significantly elevated in blood samples obtained during or within 4 hours after episodes of angina, but ...
