conclusion for more precise prediction of successful aavf maturation after spta, short-term follow-up doppler ultrasonography (< 2 weeks) was useful. if the asr was < 0.7 or if residual stenosis was ≥ 30%, immediate repeat spta is recommended. results the technical and clinical success rates were both 94.9% (56/59); the mean asr was 0.84. an asr of ≥ 0.7 and no significant residual stenosis (< ...
The aim of this study was to investigate whether brachial-ankle pulse wave velocity (baPWV) is associated with the severity of coronary artery disease (CAD) assessed by coronary computed tomography angiography (CCTA), and to evaluate baPWV as a predictor of obstructive CAD on CCTA. A total of 470 patients who underwent both baPWV and CCTA were included. We evaluated stenosis degree and plaque c...
The role of carotid stenosis on cognition remains to be determined. To study whether people with stenosis of the carotid artery have increased cognitive impairments, we studied 53 patients with moderate or severe carotid stenosis (with no symptoms of stroke or dementia) and 53 controls. We describe which cognitive functions were impaired in the patients and whether there were differences based ...
BACKGROUND The physiological assessment of angiographically intermediate-severity stenoses remains problematic. Functional measurements of poststenotic intracoronary Doppler coronary flow reserve can be performed in humans but have not been correlated with hyperemic myocardial perfusion imaging or angiographic data in this patient population. METHODS AND RESULTS Thirty-three patients undergoi...
