Comparison of diagnostic accuracy of dual-axis rotational versus standard coronary angiography

This study aimed to compare the diagnostic accuracy of DARCA versus standard coronary angiography (SA). 70 patients with possible CAD underwent SA following by DARCA were prospectively enrolled. The primary endpoint was the non-inferiority comparison of the two modalities regarding diagnosis of CAD. Coronary lesion assessment, quantitative coronary angiography (QCA) analysis, and screening adequacy comparisons were performed. All images were analyzed by two independent reviewers except QCA analysis that was analyzed by the third independent reviewer. Radiation dose, contrast usage and procedural time were recorded. This trial is registered with ClinicalTrials.gov, Number NCT01776866. 63 of 70 patients were analyzed. DARCA was non-inferior to SA regarding the diagnosis of CAD (reviewer one —positive agreement: 100%, negative agreement: 100%,p = 1;p = 0.003 for non-inferiority; reviewer two—positive agreement: 96%, negative agreement: 95%,p = 1;p = 0.016 for non-inferiority). All reviewers showed good agreement between the two modalities for the diagnosis of CAD, coronary lesion assessment, QCA analysis, and screening adequacy, as reflected by kappa coefficients between 0.61 and 1.00. DARCA was associated with 41% reduction in radiation dose, 30% in contrast usage and 29% in procedure time (allp

We report recent trends and predictors of ACS hospitalisation LOS in New Zealand. METHODS: Using routine national hospitalisation datasets, we calculated mean LOS for ACS admissions annually from 2006 to 2016, by demographics, ACS subtype and ACS procedures (coronary angiography, percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG)). We also identified predictors of longer LOS. RESULTS: Among 185,962 ACS hospitalisations, mean LOS decreased from 7.8 to 6.7 days between 2006 and 2016 (adjusted decrease = -0.18 days/year). Decline in LOS was observed for all demographic subgroups by age...

This study aimed to determine the association of the plasma FGF23 concentration with intracranial cerebral atherosclerosis (ICAS) and extracranial cerebral atherosclerosis (ECAS). METHODS: We prospectively enrolled 262 first-ever ischemic stroke patients in whom brain magnetic resonance was performed and a blood sample acquired within 24 h after admission. Plasma FGF23 concentrations were measured using an enzyme-linked immunosorbent assay. The presence of ICAS or ECAS was defined as a ≥50% decrease in arterial diameter in magnetic resonance angiography. The burden of cerebral atherosclerosis was calculated by addin...

Conclusions: This study on ICAS revealed certain trends of longitudinal distribution of WSS and pressure and the influences of percent stenosis on cerebral hemodynamics, as well as the correlations between WSS and pressure drop. It represents a step forward in applying computational flow simulation techniques in studying ICAS and stroke, in a patient-specific manner.

Objective: An enlarged perivascular space (EPVS) is an imaging marker of cerebral small vessel disease, and its relationship with large artery disease is elusive. We investigated the EPVS in patients with internal carotid artery stenosis (ICAS) with the use of digital subtraction angiography (DSA) and tested the relationship between the degree of EPVS and the degree of ICAS; as well as the relationship between the degree of EPVS and white matter hyperintensity (WMH). Method: A total of 202 patients with or without ICAS diagnosed by DSA were enrolled.
