Impact of Fried Frailty Phenotype on Postoperative Outcomes After Durable Contemporary Mechanical Circulatory Support: A Single-Center Experience.
Article in Cardiology research, 2022. 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
Background: Frailty is prevalent in advanced heart failure patients and may help distinguish patients at risk of worse outcomes. However, the effect of frailty on postoperative clinical outcomes is still understudied. Therefore, we aim to study the relationship between frailty and postoperative clinical outcomes in patients undergoing long-term mechanical circulatory support (MCS). Methods: Forty-six patients undergoing durable MCS (left ventricular assist device and total artificial heart) placement at our medical center were assessed for frailty pre-implant. Frailty was defined as ≥ 3 physical components of the Fried frailty phenotype. Our primary endpoint is 1 year of survival post-implant. Secondary endpoints include 30-day all-cause rehospitalization, pump thrombosis, neurological event (stroke/transient ischemic attack), gastrointestinal bleeding, and driveline infection within 12 months post-MCS support. Results: Of the 46 patients, 32 (69%) met the criteria for frailty according to Fried. The cohort's median age was 67.0 years. The frail group had statistically significant lower left ventricular ejection fraction (LVEF) (11% vs. 20%, P = 0.017) and lower albumin (3.5 vs. 4.0 g/dL, P = 0.021). The frail cohort also had significantly higher rates of comorbid chronic kidney disease (47% vs. 7%, P = 0.016). There were no differences between the frail vs. non-frail group in terms of 30-day readmission rates (40% vs. 39%, P = 0.927) and 1-year post-intervention survival (log-rank, P = 0.165). None of the other secondary endpoints reached statistical significance, although the incidence of gastrointestinal bleed (24% vs. 16%, P = 0.689) and pump thrombosis (8% vs. 0%, P = 0.538) were higher in the frail group. Conclusions: Preoperative Fried frailty was not associated with readmission at 30 days, mortality at 365 days, and other postoperative outcomes in long-term durable MCS patients. Findings may need further validation in larger studies.
