Two Strikes: A Case Study of Consecutive St-Elevation Myocardial Infarctions (Stemi) in two Different Coronary Arteries.
Article in European journal of case reports in internal medicine, 2024. 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
An acute ST-elevation myocardial infarction (STEMI) followed by reinfarction within a short period of time is typically due to stent thrombosis. However, a STEMI caused by occlusion of one vessel followed by a repeat infarction due to occlusion of a different vessel which was seemingly innocent a few hours earlier is extremely rare. We present the case of a 61-year-old male with a past medical history of prediabetes, hyperlipidemia, tobacco use, and gastroesophageal reflux disease who presented to the emergency department with complaints of chest pain. His initial electrocardiogram (EKG) revealed ST elevation in leads II, III and aVF with reciprocal changes in leads I and aVL. He promptly underwent cardiac catheterization and had percutaneous coronary intervention with placement of two drug-eluting stents (DES) in the right coronary artery (RCA). At that time coronary angiography revealed 50% stenosis of the left anterior descending (LAD) artery and 60% stenosis of the second diagonal branch artery. Shortly after the procedure he was asymptomatic, and the post procedure EKG demonstrated resolution of the ST elevations. However, within 2 hours he developed chest pain and was found to have new ST elevations in the anterolateral leads. Repeat cardiac catheterization revealed patent RCA stents with subtotal occlusion of the LAD and another DES was placed. After the second procedure the patient remained hemodynamically stable, EKG changes resolved, and he was kept on eptifibatide infusion for 18 hours after which he was switched to dual antiplatelet therapy and ultimately discharged home. LEARNING POINTS: Physicians should promptly address the recurrence of symptoms following an initial ST-elevation myocardial infarctions (STEMI) and be proactive regarding follow-up with the appropriate investigations.Although recurrence of STEMI within a few hours is extremely rare, the first 2 weeks following an initial STEMI is a critical time and patients should be educated on symptoms that will require further evaluation.The mortality associated with early recurrent myocardial infarction is up to 50% in 5 years so these patients require strict outpatient follow-up and counseling to minimize risk factors.
