Clinical Characteristics and Outcome of Patients With Myocardial Infarction With Nonobstructive Coronary Arteries in Japan: Insights From the Miyagi Acute Myocardial Infarction Registry Study.
Observational study in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundClinical characteristics and outcomes of patients with myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) are not fully understood, particularly in Japan. METHODS AND
resultsWe enrolled a total of 8881 patients with acute MI from the Miyagi Acute Myocardial Infarction Registry Study (2012-2020), with a median age of 69 years. Among them, 239 patients (2.7%) were diagnosed with MINOCA. Compared with those with MI with obstructive coronary artery disease (MI-CAD), patients with MINOCA were more often women, had a higher incidence of non-ST-segment-elevation MI and a lower prevalence of dyslipidemia. Compared with patients with MI-CAD, patients with MINOCA in all age groups (<59, 60-69, 70-79, >80 years of age) had a higher incidence of non-ST-segment-elevation MI. Additionally, those ≤59 years of age were more often women and had a lower prevalence of diabetes and dyslipidemia. In-hospital mortality increased with age in patients with MI-CAD (3.9% for <59 years of age, 5.6% for 60-69 years of age, 8.3% for 70-79 years of age, and 15.2% for >80 years of age;
conclusionsPatients with MINOCA exhibit distinct clinical characteristics and outcomes compared with those with MI-CAD, particularly in terms of age, sex, prevalence of comorbidities, and in-hospital mortality. These findings underscore the importance of tailored clinical approaches for patients with MINOCA.
