Longitudinal strain in remote non-infarcted myocardium by tissue tracking CMR: characterization, dynamics, structural and prognostic implications.

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
purposeIn ST-segment elevation myocardial infarction (STEMI) patients, longitudinal strain (LS) in remote non-infarcted myocardium (RNM) has not yet been characterized by tissue tracking (TT) cardiovascular magnetic resonance (CMR). In STEMI patients, we aimed to characterize RNM-LS by TT-CMR and to assess both its dynamics and its structural and prognostic implications.
methodsWe recruited 271 patients with a first STEMI studied with TT-CMR 1 week after infarction. Of these patients, 145 underwent 1-week and 6-month TT-CMR and were used to characterize both the dynamics and the short-term and long-term structural implications of RNM-LS. Based on previously validated data, RNM areas were defined depending on the culprit coronary artery.
resultsReduced RNM-LS at 1 week (n = 70, 48%) was associated with larger infarct size and more depressed left ventricular ejection fraction (LVEF) at both the 1-week and 6-month TT-CMR (p value < 0.001). Late normalization of RNM-LS was frequent (28/70, 40%) and independently related to late recovery of LVEF (p value = 0.002). Patients with reduced RNM-LS at 1-week TT-CMR had more major adverse cardiac events (death, heart failure or re-infarction) in both the 271 patients included in the study group (26% vs. 11%, p value = 0.002) and in an external validation cohort made up of 177 STEMI patients (57% vs. 13%, p value < 0.001).
conclusionAfter STEMI, reduced RNM-LS by TT-CMR is common and is associated with more severe short- and long-term structural damage. There is a beneficial tendency towards recovery of RNM-LS that parallels late recovery of LVEF. More events occur in patients with reduced RNM-LS.
