Aortic velocity propagation: A novel echocardiographic method in predicting atherosclerotic coronary artery disease burden.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe major burden of cardiovascular disease mortality around the globe is due to atherosclerosis and its complications. Hence its early detection and management with easily accessible and noninvasive methods are valuable. Aortic velocity propagation (AVP) through color M-mode of the proximal descending aorta determines aortic stiffness, reflecting atherosclerosis. The aim of this study was to find the utility of AVP in predicting coronary artery disease (CAD) burden assessed through SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) score and compared with carotid intima-media thickness (CIMT), which is an established surrogate marker of atherosclerosis.
methodsIn this cross-sectional comparative study, we measured AVP by color M-mode and CIMT by using Philips QLAB-IMT software in 100 patients, who underwent conventional coronary angiogram (CAG) between May 2013 and November 2014. Coronary artery disease is considered significant if >50% diameter stenosis is present in any epicardial coronary artery and insignificant if otherwise.
resultsInitially, to know the normal range we measured AVP and CIMT in 50 patients without any major risk factors for CAD but CAG was not done. Aortic velocity propagation ranged from 46 cm/s to 76 cm/s (mean = 58.62 ± 6.46 cm/s), CIMT ranged from 0.50 mm to 0.64 mm (mean = 0.55 ± 0.03 mm). Among 100 patients who underwent CAG we found 69% had significant CAD, 13% had insignificant CAD, and 18% had normal coronaries. Those with significant CAD had significantly lower AVP (41.65 ± 4.94 cm/s) [F (2,97) = 44.05,
conclusionsAVP and CIMT can predict CAD burden in a robust way. AVP may emerge as an exquisite bedside tool to predict atherosclerotic burden and guide in implementing preventive therapy for cardiovascular disease.
