Left Atrial Contractility in Ischemic Heart Disease Patients with Left Ventricular Systolic Dysfunction.
Article in Journal of cardiovascular echography. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLeft atrial (LA) active emptying plays an important role in left ventricular (LV) filling. It not only depends on LA preload but also on LA contractility. Our aim was to assess LA wall contraction velocity (LAWV) and its relation to each of LA active stroke volume index (LAASVI) and LA active emptying fraction (LAAEF) as markers of LA active emptying in patients with ischemic heart disease (IHD) and impaired LV systolic function.
methodsWe studied 50 consecutive patients with stable IHD and LV ejection fraction <45% and 50 healthy controls. Standard echocardiography assessed: Biplane LV volumes and ejection fraction, trans-mitral Doppler E and A wave velocities and E/A ratio, indexed biplane LA volumes pre- and post-atrial contraction, LAASVI and LAAEF. LAWV was measured by tissue Doppler imaging.
resultsTrans-mitral Doppler A velocity was lower in the study group 60.64 ± 20.6 vs 72.46 ± 17.13 cm/s (
conclusionIn patients with IHD and impaired LV systolic function, LA wall contractility is reduced. However, LAASVI and LAAEF are enhanced.
