Characteristics of pulmonary hypertension in adults with left ventricular diastolic dysfunction.
Article in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesLeft ventricular diastolic dysfunction (LVDD) is commonly associated with pulmonary hypertension (PHT); however, the factors associated with the presence and severity of PHT in patients with LVDD have not been well characterised.
methodsWe analysed the profiles and echo characteristics of 16 058 adults with LVDD and preserved left ventricular ejection fraction (LVEF, >50%) from the National Echocardiography Database of Australia. Peak tricuspid regurgitation velocity (TRV) was used to determine the presence of PHT. Univariate and multivariate analyses were performed to evaluate the parameters associated with the presence/increasing severity of PHT.
resultsMean age was 73±12 years and 9216 (57.4%) were women. 2503 (15.6%) subjects had atrial fibrillation (AF) and 13 555 (84.4%) were in sinus rhythm. Overall, 9976 (62.1%) had PHT (TRV >2.9 m/s). There was a progressive increase in indexed left atrial volume with rising TRV levels. AF and right ventricular (RV) dilation were strongly associated with the presence of PHT (adjusted OR (aOR) 1.27 (95% CI 1.12 to 1.43) and aOR 4.99 (95% CI 4.44 to 5.62), respectively). Increased age, LVEF and body mass index were also independently associated with PHT (p<0.001). On multivariate analysis, older age, female sex, AF, lower E/e' and LVEF were independently associated with the severity of PHT (p<0.001). The presence of AF increased the TRV by an average of 0.32 m/s, RV dilation by 1.82 m/s, female sex by 0.32 m/s and age (per decade) by 0.3 m/s.
conclusionIn this large study, PHT was common in LVDD and was strongly associated with the presence of enlarged left atrium, AF and older age, in particular. TRIAL REGISTRATION NUMBER: ACTRN12617001387314.
