Heart Failure with Reduced Ejection Fraction: what the trials found

SGLT2 inhibitors were evaluated for their impact on cardiac dimensions, specifically showing no significant change in Left Ventricular End-diastolic Dimension (LVEDD) 1. In a separate study of dapagliflozin, patients showed a statistically significant improvement in the Kansas-City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS) at 16 weeks, though no significant changes were observed in physical limitation scores or 6-minute walk distance 7.

Regarding LCZ696, trials demonstrated that a significantly higher percentage of patients achieved and maintained either a 100 mg or 200 mg dose compared to the control group 3. Additionally, high numbers of participants successfully tolerated LCZ696 for at least two weeks across different RAAS strata 11.

Sodium zirconium cyclosilicate was shown to significantly increase the proportion of patients achieving a response defined by serum potassium levels between 3.5 and 5.0 mEq/L while on spironolactone (≥25 mg daily) compared to standard care 4. Omecamtiv Mecarbil resulted in a statistically significant decrease in total workload during cardiopulmonary exercise testing at week 20, though changes in peak oxygen uptake and ventilatory efficiency were not significant 6.

Vericiguat was also evaluated in an established phase 4 trial for this condition 5.

Recent results — preliminary, needs further review

  • * A heart failure polypill showed varying adherence ratios to individual components of GDMT (ranging from 71.1% to 83.7%) and resulted in blood pressure readings of 126 and 124 mmHg 2. * The CardioMEMS™ HF System did not show statistically significant differences in the composite outcome of heart failure hospitalizations, intravenous diuretic visits, and all-cause mortality 14. * A best practice alert for HFrEF notification and recommended therapies resulted in a higher percentage of patients with an increase in prescribed HFrEF therapy compared to standard care 15.

For the clinician treating this condition

  • SGLT2 inhibitors (specifically dapagliflozin) are associated with improved symptom scores (KCCQ-TSS), though they may not significantly impact 6-minute walk distance or physical limitation scores [1, 7].
  • Sodium zirconium cyclosilicate effectively improves the likelihood of patients maintaining spironolactone therapy while achieving target potassium levels 4.
  • LCZ696 shows high rates of dose achievement and tolerability across different RAAS strata [3, 11].
