Hemodynamic-GUIDEd management of Heart Failure (GUIDE-HF)
Bibliographic record
Abstract
Background Hemodynamic-guided heart failure (HF) management using pulmonary artery (PA) pressures reduces HF hospitalizations (HFHs) in previously hospitalized HF patients with New York Heart Association (NYHA) class III symptoms. It remains uncertain whether this approach reduces not only HFHs but all-cause mortality and if benefits extend to patients with NYHA class II and IV HF or to those symptomatic patients with elevated natriuretic peptides without recent HFH. Methods GUIDE-HF is a prospective trial with 2 arms enrolling patients with HF regardless of ejection fraction (EF). The randomized arm is a single-blind, randomized, controlled trial of PA pressure-guided therapy in NYHA class II-IV patients (n = 1,000) with either a previous HFH or elevated natriuretic peptides (B-type natriuretic peptide/NT-pro–B-type natriuretic peptide). All consenting subjects will receive an implantable PA pressure sensor (CardioMEMS HF System) followed by randomization to either a treatment group, managed with provider remote access to the hemodynamic data, or a control group, managed without provider access to these data. Subjects in the control group will receive scheduled, scripted, sham contacts from the study team to maintain blinding as to their study group assignment. The primary study end point is the composite of cumulative HF events and all-cause mortality at 12 months. Secondary end points include quality-of-life and functional assessments. The single arm of the trial is an observational arm in which NYHA class III patients (n = 2,600) with either a previous HFH or elevated natriuretic peptides (but no recent HFH) will be implanted with a PA pressure sensor and observed for occurrence of the primary composite end point of cumulative HF events and mortality at 12 months. This arm will test the hypothesis that hemodynamic-guided care is similarly effective in HF patients enrolled on the basis of elevated natriuretic peptide levels but no recent HFH and those with a recent HFH. Conclusions GUIDE-HF is the largest clinical trial of hemodynamic-guided HF management across a broad population of HF patients, with a study design and sample size adequate to examine survival, cumulative HF events, quality of life, and functional capacity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
