Sacubitril/valsartan results in higher discount in plasma NT-proBNP ranges in comparison with valsartan alone after stabilization for worsening coronary heart failure in sufferers with an ejection fraction (EF) above 40%, in accordance with late-breaking science introduced at present at Coronary heart Failure 2023, a scientific congress of the European Society of Cardiology (ESC), and revealed within the Journal of the American Faculty of Cardiology.
These information add to the proof supporting a possible remedy advantage of sacubitril/valsartan in sufferers with EF over 40% and notably in these with EF beneath regular (<60%). The findings might affect future steering for using the drug on this inhabitants, each out and in of hospital and for these with acute, power or de novo coronary heart failure.”

Pointers suggest consideration of sacubitril/valsartan to cut back hospitalizations in sufferers with coronary heart failure with preserved EF (HFpEF; EF >50%) and/or mildly diminished EF (HFmrEF; EF 41-49%). Suggestions differ all over the world, with some noting advantages are extra evident in these with EF on the decrease finish of this spectrum (i.e. beneath regular).
The PARAGON-HF trial excluded sufferers with decompensated coronary heart failure, however a post-hoc evaluation urged a bigger profit with sacubitril/valsartan in these lately hospitalized. Whether or not initiation of sacubitril/valsartan is protected and efficient in sufferers with EF over 40% stabilized after a worsening coronary heart failure occasion was unknown. As well as, additional information have been wanted in populations excluded by PARAGON-HF (estimated glomerular filtration charge [eGFR] <30 ml/min/1.73 m2, systolic blood strain <110 mmHg, and physique mass index [BMI] >40 kg/m2).
PARAGLIDE-HF evaluated the impact of sacubitril/valsartan versus valsartan on modifications in NT-proBNP, security and tolerability in coronary heart failure sufferers with EF above 40% who had been stabilized after a worsening coronary heart failure occasion. The first endpoint was the time-averaged proportional change in NT-proBNP from baseline by Weeks 4 and eight. It was chosen to reflect the PIONEER-HF trial, which discovered that amongst sufferers with coronary heart failure with diminished EF (<40%) who have been hospitalized for acute decompensated coronary heart failure, sacubitril/valsartan led to a higher discount in NT-proBNP focus than enalapril.
Sufferers have been recruited from 100 websites within the US and Canada. A complete of 466 sufferers with EF above 40% have been enrolled inside 30 days of a worsening coronary heart failure occasion (69% have been enrolled whereas in hospital). The common age was 70 years, 52% have been ladies and 22% have been Black. Members have been randomly allotted in a 1:1 ratio to sacubitril/valsartan or valsartan. The time-averaged discount in NT-proBNP was higher with sacubitril/valsartan in contrast with valsartan (ratio of change 0.85; 95% confidence interval [CI] 0.73–0.999; p=0.049).
The secondary composite hierarchical final result consisted of a) time to cardiovascular dying, b)quantity and timing of coronary heart failure hospitalizations, c) quantity and timing of pressing coronary heart failure visits and d) time averaged proportional change in NT-proBNP from baseline to Weeks 4 and eight. This final result was evaluated utilizing a win ratio evaluation, which considers the scientific hierarchy and timing of every element of the endpoint. Extra critical occasions are given a better precedence and are analyzed first. The hierarchical final result favored sacubitril/valsartan (as did every of the elements) however was not vital (unmatched win ratio 1.19; 95% CI 0.93–1.52; p=0.16).
Relating to different secondary endpoints, in contrast with valsartan, sacubitril/valsartan diminished worsening renal perform (odds ratio [OR] 0.61; 95% CI 0.40–0.93). There was extra symptomatic hypotension within the sacubitril/valsartan group (OR 1.73; 95% CI 1.09–2.76). Importantly, subgroup analyses confirmed proof of a bigger remedy impact in these with EF ≤60% for the change in NT-proBNP (0.78; 95% CI 0.61-0.98) and the hierarchical final result (win ratio 1.46; 95% CI, 1.09–1.95).
Dr. Mentz stated: “PARAGLIDE-HF enhances PARAGON-HF by specializing in sufferers stabilized after a worsening coronary heart failure occasion with EF above 40% much like the way during which PIONEER-HF complemented PARADIGM-HF in sufferers with diminished EF. PARAGLIDE-HF had no run-in interval, allowed each newly recognized coronary heart failure and improved EF, included these with acute coronary heart failure with out particular echocardiographic necessities and general had a various examine inhabitants (52% ladies, 22% Black people). The trial additionally permitted sufferers with eGFR down to twenty ml/min/1.73 m2, systolic blood strain as little as 100 mmHg, and any BMI. The broad and various inhabitants included in PARAGLIDE-HF helps the generalisability of those information to related sufferers seen in routine apply.”
