Stroke in patients with left ventricular assist device (LVAD): who is at risk?-a retrospective observational study at a tertiary care center.
Article in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: Stroke is a severe complication in patients with left ventricular assist devices (LVAD), significantly affecting quality of life and potentially leading to death. This study aimed to illustrate the clinical features, outcomes, and risk factors associated with stroke in LVAD patients, with the goal of identifying potential treatment targets. Methods: In a study of 249 consecutive patients who underwent LVAD implantation, detailed evaluations were conducted regarding clinical characteristics, perioperative management, cardiovascular risk factors, comorbidities, and brain imaging. The etiology, treatment, and outcomes were subsequently assessed in individuals who encountered a stroke. Results: Eighty-three cerebrovascular events (CVE) occurred in 54/249 patients during a median study period of 2.2 years (0.4-3.5) with 53 ischemic events and 22 intracranial hemorrhages (ICH). Early peri- or postoperatively CVE in context to the LVAD implantation were identified in 31 patients. Competing risks regression analysis revealed that postoperative dialysis was associated with higher risk for CVE, considering death as competing risk event (HR 3.617; 95%-CI: 1.78-7.35; Conclusion: Patients who require postoperative dialysis face a heightened risk for early cerebrovascular events (CVE) during and after LVAD implantation. Additionally, a history of stroke and complicated clinical courses should increase awareness regarding the potential for impending CVE in the long term.
