Sex Differences in Diastolic Function Following Myocardial Infarction on Doppler Echocardiography.

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
backgroundWhilst females have relatively greater preservation of left ventricular ejection fraction (LVEF) following myocardial infarction (MI), they have higher rates of heart failure, presumably due to diastolic dysfunction (DD). This study sought to assess sex differences in LV diastolic function on Doppler echocardiography following MI.
methodsData on 2505 consecutive patients with a first-ever MI (defined using the Universal Definition of MI) between 2013 and 2020 were included. Echocardiography was performed within 24 h of admission. Significant DD was defined as grade 2 + 3 DD according to current ASE/EACVI guidelines. Diastolic function score (DFS) was calculated by summing the number of abnormal parameters out of the four key diastolic parameters (e' velocity, E/e' ratio, left atrial volume index [LAVI], and tricuspid regurgitation velocity [TRV]).
resultsCompared to males, females were older, had greater co-morbidity, less 3-vessel disease, higher LVEF (55.0 + 9.8% vs. 52.7 ± 9.8%, p < 0.001), and a greater proportion with LVEF > 50% (74.4% vs. 66.2%, p < 0.001). On group comparisons between sexes, LAVI, e' velocity, E/e' ratio, significant DD, and DFS showed greater abnormalities in females. In multivariable models incorporating clinical, angiographic and echocardiographic data to determine independent predictors of diastolic parameters, female sex was independently associated with abnormal LAVI (OR 1.40, p = 0.017), E/e' ratio (OR 2.86, p < 0.001), TRV (OR 1.88, p = 0.004), significant DD (OR 2.12, p < 0.001) and DFS (OR 2.59, p < 0.001).
conclusionsFemale sex is a strong independent predictor of DD on Doppler echocardiography in patients with a first-ever MI. This may explain the higher incidence of heart failure despite relatively preserved LVEF in females following MI.
