MINOCA (Myocardial Infarction With Non-obstructive Coronary Arteries) Due to Diffuse Coronary Microvascular Dysfunction in a Patient With Systemic Autoimmune Disease and Chronic Kidney Disease.
Article in Cureus, 2026. 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
Myocardial infarction with non-obstructive coronary arteries (MINOCA) represents a heterogeneous entity requiring systematic exclusion of alternative diagnoses and identification of the underlying mechanism. Coronary microvascular dysfunction (CMD) is an important but often underdiagnosed cause. Systemic inflammatory flares may precipitate microvascular ischemia, yet direct multimodality confirmation remains limited. A 51-year-old woman with active perinuclear anti-neutrophil cytoplasmic antibody (P-ANCA) vasculitis, rheumatoid arthritis, and stage 3b chronic kidney disease presented with acute chest pain, dynamic ST-segment changes, and a rise in high-sensitivity troponin T (peak 2,526 pg/mL), fulfilling criteria for acute myocardial infarction. Coronary angiography demonstrated non-obstructive coronary arteries (<50% stenosis). Cardiac magnetic resonance imaging (including T1 mapping, T2 mapping, and LGE) excluded myocarditis, stress cardiomyopathy, and infiltrative disease. Invasive coronary physiology revealed impaired coronary flow reserve (CFR 1.7) and an elevated index of microvascular resistance (IMR 32). Acetylcholine provocation excluded epicardial vasospasm.
