Blood Pressure, Safety and Clinical Efficacy of Vericiguat in Chronic Heart Failure with Reduced Ejection Fraction: Insights from the VICTOR Trial
Bibliographic record
Abstract
AIMS: The efficacy and safety of vericiguat in patients with chronic heart failure with reduced ejection fraction (HFrEF) on contemporary heart failure (HF) therapies and without recent worsening was investigated in the VICTOR trial, yet some subgroups may be more susceptible to symptomatic hypotension. METHODS AND RESULTS: Among VICTOR trial participants that received at least one dose of study drug or placebo, we describe the systolic blood pressure (SBP) trajectories over time (mean change from baseline), symptomatic hypotension events and efficacy of vericiguat in potentially vulnerable patient subgroups: lower baseline blood pressure (SBP ≤110 mmHg), older patients (>75 years) and those taking angiotensin receptor-neprilysin inhibitors (ARNI) or sodium-glucose co-transporter 2 inhibitors (SGLT2i) at baseline. The efficacy outcomes of cardiovascular death and HF hospitalization and cardiovascular death alone across baseline SBP were examined using Cox proportional hazards models. Overall SBP trajectories showed a small initial decline from baseline in vericiguat-treated patients compared with placebo (placebo-corrected differences of -1.17 [-1.84, -0.50], p = 0.0007) that was relatively stable throughout follow-up. This trajectory was similar in those >75 years (vs. younger) as well as those receiving ARNI or SGLT2i (as compared with those not receiving these) or those with SBP ≤110 mmHg at baseline (compared with >110 mmHg). Symptomatic hypotension occurred in 11.3% of vericiguat-treated patients compared with 9.2% of placebo-treated patients with an adjusted hazard ratio of 1.24 (95% confidence interval 1.06-1.46), which was similar across age, SBP, SGLT2i and ARNI groups (all interaction p >0.05). The treatment effect of vericiguat compared with placebo on the efficacy outcomes was similar across the spectrum of baseline SBP (both interaction p >0.15). CONCLUSIONS: Vericiguat showed a slight adjusted decrease in SBP and resulted in more symptomatic hypotension compared with placebo but was overall well-tolerated in a broad population with HFrEF on contemporary therapy even among those predisposed to hypotension. Treatment effects on efficacy outcomes were consistent regardless of baseline SBP.

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.
