Ongoing Opioid Treatment and Symptoms of Myocardial Infarction in Calls to the Emergency Medical Services.

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
Background: Ongoing opioid treatment can potentially modify symptoms of myocardial infarction (MI) and cause a lack of recognition and treatment delay. Objectives: The purpose of this study was to examine MI symptoms and the time to hospitalization for patients in ongoing opioid treatment compared to patients without ongoing opioid treatment. Methods: We evaluated calls to the Copenhagen Emergency Medical Services in Denmark from 2014 to 2018. Calls were included when followed by hospitalization and a diagnosis of MI. Symptoms of MI and the time from call to hospitalization in patients in ongoing opioid treatment initiated prior to the onset of MI were compared to a control group of MI patients without opioid treatment. Results: In total, 6,633 calls were included; 552 calls from patients in opioid treatment and 6,081 calls from controls. Patients in opioid treatment were older and had more comorbidities than controls. Chest pain was less prevalent in MI patients in opioid treatment compared to controls (adjOR: 0.70; 95% CI: 0.57-0.85). The median time from the call to hospitalization was longer in patients in opioid treatment than in controls (50 vs 47 minutes; Conclusions: In calls to the Emergency Medical Services, opioid treatment initiated prior to the onset of MI was associated with less frequent chest pain in MI. Therefore, awareness of ongoing opioid treatment may improve telephone triage of patients with MI, as symptom presentation in opioid-treated patients may differ and potentially challenge and delay the emergency response.
