Effectiveness of Vericiguat on right ventricle to pulmonary artery uncoupling associated with heart failure with reduced ejection fraction.

A soluble guanylyl cyclase stimulator vericiguat has been shown to reduce cardiovascular mortality or hospitalization for heart failure in patients with worsening heart failure in the VICTORIA study. However, little is known about the effects of vericiguat on biventricular structure and function. A retrospective analysis of 63 consecutive patients with heart failure with reduced ejection fraction (HFrEF) who were treated with vericiguat was performed. Clinical data and echocardiographic parameters were compared between baseline and follow-up after the initiation of vericiguat. The median follow-up duration was 266 days. Treatment with vericiguat significantly reduced the plasma BNP levels (log-transformed) compared to baseline (2.46 ± 0.51 vs. 2.14 ± 0.58, p < 0.0001). Left ventricular end-diastolic volume index and left ventricular end-systolic volume index were significantly reduced (LVEDVI, 113.5 ± 46.3 vs. 103.6 ± 51.0, p = 0.0056; LVESVI, 82.0 ± 41.9 vs. 72.8 ± 44.7, p = 0.0077; respectively). The tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) ratio, an indicator of right ventricle-pulmonary artery (RV-PA) coupling, increased significantly after the treatment (0.56 ± 0.29 vs. 0.92 ± 1.09, p < 0.0001). Univariate and multivariate analyses showed that the treatment effects of vericiguat on BNP levels, LV reverse remodeling, and RV-PA coupling were not correlated with the achievement of the quadruple therapy with beta-blockers, renin-angiotensin system inhibitors, mineralocorticoid inhibitors, and sodium-glucose cotransporter-2 inhibitors, nor with worsening heart failure (WHF). Treatment with vericiguat improved adverse LV remodeling and RV-PA uncoupling in HFrEF patients. These effects were independent of WHF and achieving the quadruple therapy. Patients with HFrEF may benefit from early initiation of vericiguat to prevent biventricular adverse remodeling.

The treatment effects were independent of the quadruple therapy and WHF. • Clinical implications: Patients with HFrEF may benefit from early starting of vericiguat to prevent progression of biventricular adverse remodeling.
