Variation in Cardiac Vein System is Associated with Coronary Artery Calcium - A Venous-Atherosclerosis Paradox?

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 factors that determine the different patterns of venous anatomy are not well understood. This study was designed to evaluate the relationship between variation in the cardiac vein system and the extent of coronary artery calcium score (CACS).
methodsWe reviewed the results of 64-slice CTs of 226 subjects (age 57.2 ± 11.2; 133M) enrolled in our study. The subjects were divided into 3 groups based on coronary artery calcium: 92 patients. with CACS = 0 AU (Agatston Unit, AU); 56 with CACS = 1-100 AU; and 78 patients with CACS > than 100 AU. The cardiac venous system was reconstructed during the optimal phase of the cardiac cycle in each subject.
resultsSubjects with a higher CACS had a better quality of vein images (p < 0.01). The number of visible veins differed between the groups. Eight subjects (8.7%) in the group with CACS = 0 AU, 7 (12.5%) in the group with CACS = 1-100 AU, and 23 (29.5%) in the group with CACS > 100 AU had five or more visible veins (p < 0.001), whereas the proportion of subjects with less than three visible veins was 56 (60.8%), 31 (55.4%) and 30 (38.4%), respectively (p < 0.05). The number of visible veins correlated with CACS (r = 0.28; p < 0.05). In a multivariate regression analysis, which included age, gender, CACS, LV ejection fraction, myocardial volume and heart rate, the CACS was found to be an independent determinant of the number of visible veins (p < 0.05).
conclusionsThe results of our study suggested that there is a link between a variation in the cardiac venous system and the extent of atherosclerosis. KEY WORDS: Coronary artery calcium score (CACS); Computed tomography; Coronary veins.
