What the trial was testing
The trial enrolled 465 patients with heart failure. The study was sponsored by Novartis Pharmaceuticals and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was long-term safety (phase 4). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Sacubitril-valsartan reduced left atrial volume by 2.8 mL/m² more than enalapril in 12 weeks.
JAMA · 2019 · NCT02874794
These findings — that sacubitril-valsartan shrank the upper heart chamber more than enalapril — were published in the JAMA and represent the headline result of the study.
Researchers tracked outcomes across 465 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with heart failure, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Both sacubitril-valsartan and enalapril are FDA-approved for heart failure with reduced ejection fraction. This study showed sacubitril-valsartan may help the heart remodel better. Talk to your cardiologist about which medication is right for your type of heart failure.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
Open heart failure trials
Targeting Breathing Limitations to Improve Functional Outcomes in HFpEF
The overall purpose of this study is to investigate whether pulmonary limitations that increase the oxygen (O2) cost of breathing impact dyspnea on exertion (DOE) and peak exercise capacity in patients with HFpEF and obesity. As per investigator's hypothesis, obesity is likely a significant contributor to DOE and exercise intolerance in patients with HFpEF.
A Post Market Surveillance Study of the Hemovent Extracorporeal Cardiopulmonary Support System:The MOBYBOX Trial
The purpose of this study is to evaluate prospectively the safety and performance of the MOBYBOX System in the veno-arterial configuration in patients with cardiorespiratory failure or in the veno-venous configuration in patients with severe respiratory failure.
