Heart Failure With Reduced Ejection Fraction Is Associated With Greater Cardiovascular Risk Following Lumbar Interbody Fusion.
Article in Global spine journal, 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
Study DesignRetrospective cohort study.ObjectiveTo compare perioperative cardiovascular outcomes between patients with heart failure with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF) following transforaminal or posterior lumbar interbody fusion (TLIF/PLIF).MethodsThe TriNetX Research Network was used to identify patients undergoing elective TLIF or PLIF between 2011 and 2025. Cohorts were defined by heart failure phenotype and propensity score-matched (PSM) 1:1 for baseline demographics and comorbidities. Outcomes included postoperative atrial fibrillation or flutter (AF/AFL), myocardial infarction (MI), and secondary complications within 90 days. Odds ratios with 95% confidence intervals were calculated. Significance was defined as p < 0.05.ResultsOf 46,431 patients, 1,253 (2.7%) had HFrEF, 1,920 (4.1%) had HFpEF, and 43,258 (93.2%) had no heart failure. After PSM, both phenotypes carried elevated risk relative to non-HF controls across measured complications, including acute respiratory failure, pneumonia, AF/AFL, acute kidney injury, venous thromboembolism, and 90-day emergency department visits (all p<0.05). In the direct phenotype comparison (1,217 matched pairs), acute MI occurred more frequently in HFrEF than HFpEF patients (14.4% vs. 8.7%, p<0.001). HFrEF was associated with greater odds of acute MI (OR 1.760 [95% CI: 1.363, 2.273], p<0.001) and AF/AFL (OR 1.278 [95% CI: 1.079, 1.513], p=0.005) compared with HFpEF.ConclusionAmong patients with heart failure undergoing TLIF or PLIF, those with HFrEF are at increased risk of postoperative AF/AFL and MI compared with HFpEF patients. These findings highlight the importance of distinguishing heart failure phenotype during preoperative risk stratification and may support enhanced perioperative precautions.
