Young ST-Segment Elevation Myocardial Infarction With Autolysis: Survival of the Blessed.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMany times, young patients with ST-segment elevation myocardial infarction (STEMI) are angina free during primary percutaneous coronary intervention and have patent infarct-related artery with TIMI flow grade 3 due to the process of autolysis. These cases pose a great challenge to the interventionist mind. This case series provides a new perspective to the management of such patients. CASE SUMMARIES: Patient 1 is a 31-year-old man who presented with STEMI. During primary percutaneous coronary intervention (PPCI), thrombus laden left anterior descending artery (LAD) with TIMI flow grade 3 was noted. Stenting was deferred and repeat coronary angiogram (CAG) after 4 weeks showed resolved thrombus and optical coherence tomography (OCT) showed healed plaque rupture. Patient 2 is a 29-year-old man who presented with STEMI of 12 hours' duration. During PPCI, mid-LAD had thrombus and TIMI flow grade 3. Stenting was deferred, and antithrombotic therapy was given. Repeat CAG showed complete resolution of thrombus, and OCT showed features of plaque erosion with adequate luminal areas. Patient 3 is a 31-year-old man undergoing treatment for nonseminomatous germinal cell tumor who presented with STEMI. During PPCI, LAD had nonocclusive thrombus with TIMI flow grade 3. Stenting was deferred and managed medically. CAG 4 weeks later showed resolution of thrombus and adequate luminal areas with a healing intramural hematoma on OCT. DISCUSSION: Young STEMIs with features of autolysis during PPCI may be managed without stent placement if they have a favorable autolysis profile. OCT in these patients helped to understand the underlying pathophysiological mechanism of STEMI.
