Comparison of regional wall motion abnormalities in patients with occlusion myocardial infarction with and without ST-elevation myocardial infarction (STEMI).

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
objectiveWe aimed to determine whether there are similar rates of regional wall motion abnormalities (RWMAs) in patients with acute coronary occlusion myocardial infarction (OMI) with and without ST-elevation myocardial infarction (STEMI) on electrocardiogram (ECG).
methodsWe performed a retrospective review of a database of patients at high risk for acute coronary syndrome with previously established outcomes for the presence of OMI in order to compare rates of RWMA in patients presenting with STEMI(+) OMI versus STEMI(-) OMI. Furthermore, we compared how often the RWMA aligned with the anatomical territory observed on ECG.
resultsAmong 808 patients, 551 underwent formal echocardiography, including 256 of 265 OMI patients and 295 of 543 patients with no occlusion. Of the 256 OMI patients that underwent formal echocardiography, only 105 (41.0%) met STEMI criteria. Among them, 94 of 105 (89.5%) STEMI(+) OMI patients had RWMAs compared to 124 of 151 (82.1%) STEMI(-) OMI patients (P=0.10; 95 confidence interval, -1.63% to 15.6%). Both groups had a greater prevalence of RWMA than the non-OMI group (45%). RWMA matched the anatomic territory predicted by ECG in 92.5% of STEMI(+) OMI, 82.3% of STEMI(-) OMI, and 2.9% of the no-occlusion cohort.
conclusionLocation of RWMAs was well-correlated with ECG findings regardless of the presence or absence of STEMI criteria. A prospective study is warranted to determine the utility of echocardiography in the detection of STEMI(-) OMI.
