Combined Left Ventricular and Left Atrial Strain Assessment for Long-Term Risk Stratification in Heart Failure With Reduced Ejection Fraction.

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
purposeLeft ventricular (LV) global longitudinal strain (GLS) and left atrial reservoir strain (LASr) are established predictors of adverse outcomes in heart failure with reduced ejection fraction (HFrEF), but the prognostic value of their combined assessment has not been fully elucidated.
methodsThis retrospective study included 341 patients hospitalized with decompensated HFrEF who underwent speckle-tracking echocardiography for assessment of LV GLS and LASr. Receiver operating characteristic (ROC) analysis with Youden index optimization was applied to determine optimal strain cutoff values and develop a combined strain classification model. Cox proportional hazards models were used to identify parameters associated with all-cause mortality. LV GLS was analyzed using absolute values.
resultsDuring a median follow-up of 59 months, 238 patients (70%) died. In univariable analysis, both LV GLS and LASr were associated with mortality. After multivariable adjustment, both remained independently associated with mortality (GLS: adjusted HR 0.945, 95% CI 0.902-0.991, p = 0.019; LASr: adjusted HR 0.972, 95% CI 0.953-0.992, p = 0.006). ROC analysis identified optimal cutoff values of 7.3% for LV GLS and 9.0% for LASr. Patients with concomitant marked impairment of both strain parameters exhibited the highest mortality risk, whereas those with the least impaired ventricular and atrial strain had the most favorable outcomes. Patients with pronounced impairment of either parameter alone demonstrated intermediate survival.
conclusionIn patients hospitalized with HFrEF, both LV GLS and LASr were independently associated with all-cause mortality. Their combined assessment may identify distinct risk phenotypes and provide enhanced risk stratification beyond either parameter alone.
