Early Differentiation of Stress Cardiomyopathy from Acute Anterior Wall Myocardial Using Changing Cardiac Enzyme Patterns.
Article in Journal of cardiovascular imaging, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundMost patients with acute anterior wall ST elevation myocardial infarction (STEMI) or stress cardiomyopathy (SCMP) show elevations in cardiac enzymes that peak within 24 hours. The changing pattern of cardiac enzymes can be an early clue to the differentiation of anterior STEMI and SCMP.
methodsThis study was a retrospective analysis (matching cases and respective control subjects) performed at a single center. We compared 27 patients with SCMP and 30 patients with anterior STEMI. We used laboratory data included cardiac marker, such as the initial creatine kinase MB (CK-MB) fraction and troponin T (Tn-T), at admission and peak CK-MB and Tn-T at follow up.
resultsThe mean age was 69.3 ± 14.1 years, and 38.6% of patients were female. The SCMP patients were older, more often female, and had lower left ventricular ejection fractions than the anterior STEMI patients. The initial CK-MB was higher in the anterior STEMI group than in the SCMP group. In contrast, the initial Tn-T level was not significantly different between the 2 groups. Peak CK-MB and Tn-T levels and change from initial levels were significantly greater in the anterior STEMI group than they were in the SCMP group. SCMP could be differentiated from anterior STEMI based on peak CK-MB > 46.65 ng/mL or Tn-T > 1.56 ng/mL.
conclusionsFollow-up changes in cardiac enzymes can be an effective early tool for differentiating SCMP from anterior STEMI.
