Incremental value of coronary computed tomography angiography in addition to invasive coronary angiography in MINOCA.
Article in The international journal of cardiovascular imaging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Patients with the working diagnosis myocardial infarction with nonobstructive coronary arteries (MINOCA) have diverse underlying causes warranting further investigations. Despite the documented superiority of coronary computed tomography angiography (CCTA) over invasive coronary angiography (ICA) in plaque detection, the former is not routinely recommended for MINOCA patients, highlighting a knowledge gap regarding CCTA's incremental value. The objective of this study is to assess the prevalence and extent of coronary atherosclerosis in MINOCA patients using CCTA, and to evaluate the incremental value of CCTA over ICA alone in detecting coronary atherosclerosis. The data from 163 MINOCA patients who underwent both CCTA and ICA in two prospective studies were retrospectively analyzed to compare the occurrence and distribution of coronary atherosclerotic plaques detected with ICA versus CCTA, evaluating CCTA's incremental value. CCTA detected coronary atherosclerosis in 48% of subjects; ICA did so in 47%. Notable disagreement, reflected by kappa values of 0.34 (95% confidence interval [CI] 0.19-0.48) across all segments and 0.41 (95% CI 0.27-0.55) for proximal segments (both p < 0.0001), highlighted discrepancies between CCTA and ICA in the detection of atherosclerosis presence and location. Combining CCTA with ICA provided significant incremental value in detecting atherosclerosis in coronary segments (p < 0.001). MINOCA patients frequently exhibit non-obstructive coronary plaques. Agreement between CCTA and ICA is poor. CCTA provides valuable additional information on atherosclerotic segments. Therefore, CCTA should be recognized as a complementary tool to ICA, aiding risk assessment and treatment decisions in the context of MINOCA.
