Pathophysiological and prognostic relevance of exercise CMR-derived pulmonary artery compliance in patients with suspected diastolic dysfunction and normal right ventricular function.

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
Aims: Right ventricular (RV) dysfunction has been associated with worse prognosis in patients with diastolic dysfunction, highlighting the importance of early detection. Main pulmonary artery (MPA) compliance may indicate adverse biventricular coupling prior to emerging RV function. Methods and results: Sixty-eight patients with suspected diastolic dysfunction (New York Heart Association ≥ II, LV EF ≥ 50%, E/e' ≥ 8) were prospectively recruited and underwent rest and stress right heart catheterization, echocardiography, and cardiovascular magnetic resonance imaging (CMR) within 24 h. Maximum ( Conclusion: In patients with suspected diastolic dysfunction and preserved RV function, exercise-stress testing unmasked decreasing CMR-derived MPA compliance, associated with LV diastolic dysfunction and indicated higher risk for cardiovascular events.
