Evaluation of the Relationship Between Aortic Stiffness and Elasticity and Left Ventricular Functional Parameters in Patients with ANOCA Using CCTA.
Article in International journal of general medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To analyze the clinical value of coronary CT angiography (CCTA) for evaluating aortic stiffness and elasticity in patients with angina and non-obstructive coronary artery (ANOCA). Methods: The case data of 120 patients who were diagnosed with ANOCA and underwent CCTA in our hospital were collected and set as the case group, and 86 healthy subjects who underwent medical check-up and ANOCA testing in our hospital during the same period were set as the control group. The differences in CCTA indices of ascending aortic stiffness and aortic elasticity, left ventricular function indices of left ventricular ejection fraction (LVEF) and cardiac output (CO) were compared between the two groups. Results: The arterial compliance (AC) and arterial distensibility (AD) values in the case group were significantly lower than those in the control group, while arterial stiffness (β) value was significantly higher in the case group compared to the control group (P<0.05). The LVEF and CO values of patients in the case group were significantly lower than those in the control group (P<0.05). The CCTA indices AC and AD of patients in the case group exhibited a significant positive correlation with their LVEF (r=0.133, r=0.062, P<0.05), while β showed a negative correlation with LVEF (r=-0.092, P=0.005). Conclusion: Aortic stiffness and elasticity in CCTA indices of ANOCA patients exhibited significant alterations, and the correlation analysis suggested a correlation of CCTA aortic stiffness and elasticity indices with left ventricular performance indices.
