How Does Opium Dependency Affect the Myocardial Infarction Outcomes? :.
Article in Galen medical journal, 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
Background: Acute Coronary Syndrome (ACS) remains a leading global cause of mortality, with multiple established risk factors. While smoking is widely recognized, opium use poses a significant health concern, particularly in developing nations. Despite traditional beliefs suggesting potential cardioprotective effects, growing evidence indicates a detrimental impact of opium consumption on cardiovascular health. This study aimed to investigate the association between opium dependence and the clinical outcomes of patients experiencing ACS. Materials and Method: This study, conducted on 165 patients with ST-elevation myocardial infarction (STEMI) and Non-ST-elevation myocardial infarction (NSTEMI) referred to the Qom Heart Center, Qom, Iran from 2022 to 2024. The patients were categorized in two groups: 81 opium-dependent patients based on DSM-V criteria as a case group and 84 non-opium-dependent patients as a control group, and their clinical outcomes were compared. Results: Coronary artery involvement was significantly more severe in opium-dependent patients ie three vessel disease (3VD) or left main stenosis (LM) involvement in the opium-dependent group was 48.1% versus 28.6% in the non-opium-dependent group, (P-value=0.01). Prevalence of atrial fibrillation (AF) and delay in hospital admission and the hospitalization days were higher in the opium-dependent group. LVEF at the admission did not differ between the two groups, but left ventricle ejection fraction (LVEF) three months later was higher in the opium-dependent group. Rehospitalization, arrhythmia, mechanical complications, need for CABG, and mortality during the initial hospitalization did not differ between the two groups. The mortality of the patients in the six-month follow-up was 6.5% in the opium-dependent group and 8.6% in the non-opium-dependent group (P-value=0.61) which did not show a significant difference. This issue shows the lack of significant role of opium consumption in the mortality of patients. Conclusion: Our findings suggest a strong association between opium dependence and a more severe clinical presentation of ACS, characterized by a higher burden of coronary artery disease. Although initial LVEF recovery appeared faster in opium-dependent individuals, the overall impact on long-term mortality remained inconclusive within the six-month follow-up period. These findings underscore the critical need for further research to elucidate the complex interplay between opium dependence and cardiovascular outcomes in ACS patients, including long-term follow-up and exploration of potential underlying mechanisms.
