The Dilemma in the Management of Patients with Heart Failure with Reduced Ejection Fraction, Sinus Rhythm and Left Ventricular Spontaneous Echo Contrast: A Narrative Review.
Review in Current cardiology reviews, 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
Heart failure (HF) is a complex clinical syndrome that arises from structural or functional impairment of ventricular filling or ejection of blood, resulting in previous characteristic symptoms of fatigue, dyspnea, and fluid retention. Among the complications of heart failure is the development of spontaneous echo contrast (SEC), characterized by a smoke-resembling appearance on echocardiograms, which indicates blood stasis in heart chambers. Despite being identified as an echocardiographic marker in the left atrium that correlates with thrombus formation and causes thromboembolic events, the clinical importance of left ventricular spontaneous echo contrast (LV-SEC) and the appropriate management for patients with this condition remain uncertain due to insufficient data. Anticoagulant therapy is generally recommended for patients with established left ventricular thrombus (LVT). However, for patients with heart failure with reduced ejection fraction (HFrEF) and sinus rhythm (SR), as a result of a decrease in thromboembolic events over time, it is typically not recommended. The main challenge lies in assessing the thromboembolic risk and determining appropriate management in patients with HFrEF, sinus rhythm (SR), and left ventricular spontaneous echo contrast (LV-SEC), compared to those with left ventricular thrombus (LVT) and those with HFrEF and SR without LV-SEC. The aim of this paper is to review the guidelines and trials on clinical characteristics, outcomes, and management of patients with LV-SEC and compare the suggested management with the established management for LVT and HF patients with sinus rhythm without LV-SEC.
