Delayed Initiation of ARNI and SGLT2i in Heart Failure With Corrected Aetiology (DELAY-HF), Pilot Study

2026年8月31日 更新者：Kyungsub Song

DELayed Initiation of ARNI and SGLT2i in Heart Failure With Corrected aetiologY (DELAY-HF), Pilot Study

In patients with heart failure due to a reversible underlying cause-such as valvular heart disease or coronary artery disease-surgical or procedural correction of the underlying lesion (valve repair/replacement, TAVI, PCI, or CABG) frequently leads to spontaneous recovery of cardiac function, even without neurohormonal modulators. In this clinical setting, a substantial proportion of patients may not require the full set of guideline-directed medical therapies routinely prescribed for chronic HFrEF. The purpose of this study is to determine whether ARNI (angiotensin receptor-neprilysin inhibitor) and SGLT2 inhibitors are truly necessary in patients whose left ventricular function recovers spontaneously after treatment of a correctable cause of heart failure.

The DELAY-HF trial (DELayed initiation of ARNI and SGLT2i in heart failure with corrected aetiologY) is a multicentre, randomised, open-label pilot trial with blinded end-point assessment (PROBE design) evaluating the safety and feasibility of a delayed-initiation strategy of ARNI and SGLT2i, compared with immediate initiation, in patients with heart failure whose underlying cause has been completely corrected by surgical or procedural intervention. A total of 80 patients (40 per arm) will be enrolled at four centres in South Korea.

Adults with a preoperative left ventricular ejection fraction (LVEF) ≤40% who have undergone successful correction of a reversible cause of heart failure-either revascularization (PCI or CABG) for ischemic cardiomyopathy or valvular surgery (including TAVI) for left-sided valvular heart disease causing volume overload-will be randomized 1:1 to (1) delayed initiation, in which ARNI/SGLT2i are withheld for 6 months and started only in patients whose LVEF remains ≤40% at the 6-month assessment, versus (2) immediate guideline-directed medical therapy (GDMT) including ARNI/SGLT2i started shortly after the corrective procedure. All patients are followed for 12 months.

The primary outcome is the absolute change in LVEF from baseline to 12 months. The between-group difference (delayed minus immediate) will be reported as a point estimate with a two-sided 95% confidence interval and evaluated against a pre-specified decision criterion (lower confidence limit above -5 percentage points). As a pilot trial, DELAY-HF is not powered for a confirmatory non-inferiority test; it aims to estimate the standard deviation of the primary outcome, recruitment and dropout rates, the rescue-therapy rate and safety data needed to design a subsequent confirmatory trial. Key secondary outcomes include cardiovascular and all-cause mortality, heart failure hospitalisation, additional echocardiographic indices, NT-proBNP, KCCQ-12 score, 6-minute walk distance, feasibility metrics, and a cost-effectiveness analysis.

By comparing these two strategies, this pilot trial will provide preliminary estimates of the incremental contribution of ARNI and SGLT2i-to further LVEF recovery and to clinical outcomes-in patients who have already demonstrated spontaneous improvement in cardiac function after correction of the underlying cause, and will inform the design of a subsequent confirmatory trial addressing whether these agents are truly necessary in this population.

详细说明

  1. Scientific Background and Rationale Contemporary heart failure (HF) guidelines recommend the early and simultaneous initiation of the four foundational pillars of guideline-directed medical therapy (GDMT)-ARNI (or ACEi/ARB), beta-blocker, mineralocorticoid receptor antagonist, and SGLT2 inhibitor-in patients with a reduced left ventricular ejection fraction (LVEF). The pivotal trials supporting these recommendations, however, were conducted predominantly in patients with chronic HFrEF in whom the underlying aetiology was either non-correctable or had not been definitively addressed.

    A clinically distinct population is encountered when the underlying cause of heart failure is fully reversible: patients with ischaemic cardiomyopathy who undergo complete revascularization, and patients with left-sided valvular disease causing chronic pressure or volume overload (severe aortic stenosis, aortic regurgitation, primary mitral regurgitation) who undergo valvular surgery or transcatheter intervention. In these patients, removal of the haemodynamic insult itself drives a substantial portion of subsequent LVEF recovery, independent of neurohormonal blockade. Consequently, universal and immediate initiation of ARNI and SGLT2i in this population may expose patients who would have recovered spontaneously to drug-related adverse effects (symptomatic hypotension, hyperkalaemia, renal dysfunction, genitourinary infection, ketoacidosis), to the burden of polypharmacy, and to avoidable cost, with uncertain incremental benefit on cardiac function or clinical outcome.

    The optimal timing of ARNI and SGLT2i initiation in patients whose underlying cause of HF has been definitively corrected has not been prospectively examined.

  2. Study Hypothesis The central hypothesis of DELAY-HF is that, in patients in whom the underlying cause of heart failure has been surgically or procedurally corrected, the LVEF recovery attributable to treatment of the underlying cause is substantially greater than the incremental recovery attributable to ARNI and SGLT2i. Under this hypothesis, the 12-month LVEF change in the delayed-initiation arm is expected to be no more than 5 percentage points worse than in the immediate-initiation arm. As a pilot trial, DELAY-HF estimates this difference with a 95% confidence interval and evaluates it against the pre-specified decision criterion; a formal non-inferiority hypothesis test will be performed in a subsequent, separately designed confirmatory trial.
  3. Pre-specified Analyses

Four pre-specified analyses are planned to fully characterise the contribution of ARNI/SGLT2i in this population:

  1. Effect of early ARNI/SGLT2i on LVEF recovery. Patients in the delayed-initiation arm who never received ARNI/SGLT2i during the 12-month follow-up (those without recovery at 6 months who were ultimately not started, plus those who recovered spontaneously) will be compared with the immediate-initiation arm to estimate the contribution of early ARNI/SGLT2i to LVEF recovery beyond the recovery driven by treatment of the underlying cause.
  2. Safety of delayed initiation. Within the delayed-initiation arm, patients who received delayed ARNI/SGLT2i and recovered will be compared with those who received delayed therapy without recovery, to evaluate whether postponing therapy by 6 months in non-recovering patients is associated with an attenuation of subsequent LVEF response.
  3. Twelve-month head-to-head comparison. The proportion of patients achieving LVEF recovery and the magnitude of LVEF improvement at the 12-month assessment will be compared directly between the delayed-initiation and immediate-initiation arms.
  4. Spontaneous versus pharmacologic recovery. Among patients in the delayed-initiation arm whose LVEF recovered spontaneously after correction of the underlying cause (without medication), the magnitude of LVEF recovery will be compared with that achieved in patients in the immediate-initiation arm whose recovery occurred while on ARNI/SGLT2i.

4. Sample Size Justification Sample Size Justification. The sample size of 80 patients (40 per arm) was not derived from a power calculation for hypothesis testing, in keeping with the exploratory purpose of a pilot trial. It is based on: (1) the recommendation of Whitehead et al. (2016) of 25-40 participants per arm for a pilot trial preceding a main trial with a standardised effect size of 0.5 (decision margin Δ = 5 percentage points, assumed SD ≈ 10 percentage points); (2) consistency with prior randomised trials of GDMT withdrawal in recovered heart failure (ReReRe n = 80, TRED-HF n = 51, CATHEDRAL-HF n = 60); (3) detection of a safety signal-approximately 80% power (Fisher's exact test, α = 0.05) to detect a rescue-therapy rate of 25% in the delayed arm versus 5% in the immediate arm; (4) estimation of feasibility metrics (recruitment, adherence, 12-month follow-up completion) within a 95% confidence interval of approximately ±10 percentage points; and (5) an allowance of 10%

5. Exploratory Analyses A pre-specified exploratory aim of the trial is to estimate the proportion of patients in the delayed-initiation arm in whom ARNI and SGLT2i can ultimately be deemed unnecessary-that is, those whose cardiac function has recovered sufficiently at 6 months that initiation is not warranted under the trial protocol. A formal cost-effectiveness analysis (incremental cost-effectiveness ratio) will compare the two strategies from the healthcare-system perspective.

6. Expected Implications If the delayed-initiation strategy proves safe and feasible in this pilot, with no clinically important signal of harm on the LVEF decision criterion, the findings will support a subsequent confirmatory trial and, ultimately, a more individualised prescribing approach in patients with a corrected cause of heart failure-reserving ARNI and SGLT2i for those who fail to recover spontaneously-thereby reducing unnecessary drug exposure, adverse-effect burden, and cost in a population that is currently treated uniformly under generalised HFrEF guidelines.

7. Safety Monitoring Safety Monitoring. An independent Data and Safety Monitoring Board (DSMB) will perform two interim safety reviews: after the first 40 patients complete 12-month follow-up and after enrolment of 80 patients. Safety data from the intensive 6-month observation period of the delayed-initiation arm (rescue-therapy rate, heart failure hospitalisation, death) will be reviewed separately by aetiology (valvular vs ischaemic). A rescue-therapy rate exceeding 20% in the delayed-initiation arm triggers a DSMB review, and stratum-specific discontinuation of enrolment may be recommended.

实验性的：Delayed initiation of ARNI and SGLT2i
After surgical or procedural correction of the underlying cause of heart failure (valvular surgery/TAVI or PCI/CABG), ARNI and SGLT2 inhibitors are withheld and patients are observed for 6 months on background therapy excluding ARNI/SGLT2i. At the 6-month assessment, ARNI and SGLT2i are initiated only in patients whose LVEF remains ≤40%. Patients with LVEF >40% continue without ARNI/SGLT2i under observation. If symptomatic heart failure worsening or a ≥10 percentage-point decrease in LVEF occurs during the observation period, full guideline-directed medical therapy including ARNI and SGLT2i is started immediately as rescue therapy. All participants are followed for 12 months from randomization.
药品：Sacubitril / Valsartan

In the delayed-initiation arm, sacubitril/valsartan is withheld for 6 months after the corrective procedure; valsartan is used for blood pressure control and background heart failure therapy. At the 6-month assessment, sacubitril/valsartan is initiated only in patients with LVEF ≤40%. Patients with LVEF >40% continue their existing regimen without ARNI.

If heart failure worsens during observation (symptomatic deterioration or a ≥10 percentage-point drop in LVEF), sacubitril/valsartan is started immediately as rescue therapy. Patients on ARNI prior to enrollment undergo a 1-week washout before randomization.

药品：SGLT-2 inhibitor

In the delayed-initiation arm, the SGLT2 inhibitor (dapagliflozin 10 mg once daily or empagliflozin 10 mg once daily) is withheld during the first 6 months and initiated at the 6-month assessment only in patients whose LVEF remains ≤40%; patients whose LVEF has recovered to >40% continue without SGLT2i under observation.

If heart failure worsens during the observation period, the SGLT2 inhibitor is started immediately as rescue therapy. Patients receiving SGLT2i prior to enrollment undergo a 1-week washout before randomization.

药品：Sacubitril / Valsartan
In the immediate-initiation arm, sacubitril/valsartan is started within 7 days after the corrective procedure, once the patient is hemodynamically stable and euvolemic. The starting dose is selected based on baseline blood pressure (25 mg to 200 mg twice daily) and titrated to the maximally tolerated dose (target 200 mg twice daily), continued throughout the 12-month follow-up.
有源比较器：Immediate initiation of ARNI and SGLT2i (standard GDMT)
After surgical or procedural correction of the underlying cause of heart failure (valvular surgery/TAVI or PCI/CABG), full guideline-directed medical therapy including ARNI and SGLT2 inhibitors is initiated and titrated to the maximally tolerated doses according to current heart failure guidelines, and continued throughout the follow-up period. All participants are followed for 12 months from randomization.

In the delayed-initiation arm, sacubitril/valsartan is withheld for 6 months after the corrective procedure; valsartan is used for blood pressure control and background heart failure therapy. At the 6-month assessment, sacubitril/valsartan is initiated only in patients with LVEF ≤40%. Patients with LVEF >40% continue their existing regimen without ARNI.

If heart failure worsens during observation (symptomatic deterioration or a ≥10 percentage-point drop in LVEF), sacubitril/valsartan is started immediately as rescue therapy. Patients on ARNI prior to enrollment undergo a 1-week washout before randomization.

药品：SGLT2 Inhibition
An SGLT2 inhibitor (dapagliflozin 10 mg once daily or empagliflozin 10 mg once daily, at the discretion of the treating physician) is used as one of the foundational therapies of guideline-directed medical therapy for heart failure. In the immediate-initiation arm, the SGLT2 inhibitor is started after correction of the underlying cause of heart failure and continued throughout the 12-month follow-up.

Change in left ventricular ejection fraction (LVEF) at 12 months
大体时间：Baseline (at randomization) and 12 months after randomization

Absolute change in left ventricular ejection fraction (LVEF), expressed in percentage points, from baseline (at randomization) to the 12-month follow-up assessment. LVEF will be measured by transthoracic echocardiography using the biplane Simpson's method according to current ASE/EACVI guidelines, and analyzed by readers blinded to treatment assignment.

The primary hypothesis is non-inferiority of the delayed-initiation strategy compared with the immediate-initiation strategy. Non-inferiority will be declared if the lower bound of the two-sided 95% confidence interval for the between-group difference in LVEF change (delayed minus immediate) lies above -5 percentage points; that is, the LVEF improvement in the delayed-initiation arm is no more than 5 percentage points worse than in the immediate-initiation arm.
