Prognostic Value of Strain by Tissue Tracking Cardiac Magnetic Resonance in Myocardial Infarction With Nonobstructive Coronary Arteries.
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. It is linked to trial NCT06502899 (Prognostic Value of CMR-related Parameters in Patients with MINOCA), which is not on this map. Cited by 2 papers.
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.

Abstract
backgroundStrain assessed by cardiac magnetic resonance (CMR) is a key prognostic indicator in myocardial infarction. However, the strain characteristics and prognostic value in myocardial infarction with nonobstructive coronary arteries (MINOCA) with different causes are unclear. This study aims to describe left atrial (LA) and left ventricular strain in patients with MINOCA and evaluate their predictive value for major adverse cardiovascular events (MACEs) in "true MINOCA" cases. METHODS AND
resultsThis single-center retrospective study included patients suspected of myocardial infarction who completed CMR during hospitalization. CMR images were used to obtain LA and left ventricular strain via CMR feature tracking. True MINOCA was defined by evidence of ischemia or infarction on CMR. MACEs included all-cause death, recurrent myocardial infarction, stroke, heart failure, atrial fibrillation, and angina pectoris. This study included 386 patients, with a median time from admission to CMR of 4 days. LA and left ventricular strains varied by pathogenesis, with the lowest strain in patients with cardiomyopathy. For patients with true MINOCA, Cox regression showed that global longitudinal strain (hazard ratio [HR], 0.90 [95% CI, 0.82-0.99];
conclusionsLA and left ventricular strains vary among MINOCA pathogeneses. In true MINOCA patients, global longitudinal strain and LA reservoir strains independently predict MACE risk. Integrating these strains enhances MACE prediction. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique Identifier: NCT06502899.
