Thromboembolic trapping and anticoagulation dilemma in a patient with heart failure and reduced ejection fraction in sinus rhythm: A case report.
Article in Radiology case reports, 2024. 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
Severe left ventricular dysfunction and ventricular wall motion abnormalities predispose individuals to thrombosis and thromboembolism. Thromboembolism is one of the main causes of increased mortality in patients with heart failure and reduced ejection fraction (HFrEF). However, regarding thromboembolism due to HFrEF in sinus rhythm, most cases to date have reported ischemic strokes, and repeated embolization of peripheral arteries has been reported not uncommon. Herein, we report the case of a 48-year-old man with a definite diagnosis of sinus rhythm HFrEF and recurrent peripheral arterial embolization within a short period. The condition is caused by severe left ventricular systolic dysfunction and abnormal left ventricular wall motion, resulting in blood stasis and abnormal blood composition, with or without left ventricular thrombosis, and can lead to thromboembolism. Current guidelines state that patients with heart failure and clear indication(s) for anticoagulation (e.g., atrial fibrillation, heart valve replacement) should be administered appropriate anticoagulation therapy. However, controversy persists regarding whether patients with HFrEF in sinus rhythm can benefit from anticoagulation therapy. This case highlights the utility and necessity of anticoagulation for the prevention of intracardiac thrombosis and the treatment of peripheral arterial embolism in patients with HFrEF in sinus rhythm.
