Heart Failure and the Non-Resolution of Atrial Thrombus Detected in Anticoagulated Patients with Non-Valvular Atrial Fibrillation.

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
BackgroundTo investigate the relationship between heart failure (HF) and the non-resolution of atrial thrombus detected in anticoagulated patients with non-valvular atrial fibrillation (NVAF).MethodsThis was a single-center, observational, retrospective, and prospective study. Anticoagulated patients with NVAF and atrial thrombus identified by transesophageal echocardiography or cardiac computed tomography angiography were consecutively enrolled. All patients received follow-up imaging within 6 months to assess the resolution of atrial thrombus. The primary endpoint was the resolution of atrial thrombus and the secondary endpoint was the occurrence of ischemic stroke, major bleeding, and all-cause death during the follow-up period.ResultsAmong 8987 patients with NVAF scheduled for catheter ablation or cardioversion, 70 anticoagulated patients with atrial thrombus were final analyzed. The average age was 61.8±10.6 years, 62.9% of them were men, and 32 (45.7%) patients presented with HF. Within the 6-month follow-up period, atrial thrombus resolution was observed in 47 (67.1%) patients. The rate of atrial thrombus resolution was lower in patients with baseline HF (50.0% vs 81.6%). In the adjusted logistic regression analysis model, HF was independently associated with the non-resolution of atrial thrombus (adjusted OR: 5.38, 95% CI: 1.19-24.27). During the median follow-up period of 4.5 years, four ischemic stroke events occurred in four patients. None of the patients in this study experienced major bleeding events or death during follow-up.ConclusionsHF was associated with the non-resolution of atrial thrombus detected in anticoagulated patients with NVAF. Further research is needed to identify optimal therapeutic approaches for this high-risk population.
