About

The goal of this clinical trial is to learn whether a rapid and intensive optimization of heart failure medications in women can improve outcomes after hospitalization for heart failure. It will also investigate the safety and the tolerance of these treatments when given at full guideline-recommended doses.

The main questions it aims to answer are:

1. Does intensive medication optimization reduce death or hospital readmissions for heart failure within one year?
2. Do women benefit as much as men from intensive and full-dose heart failure therapy?
3. Is this treatment protocol safe and feasible also in women?

Researchers will compare two groups of women hospitalized for heart failure:

• High-intensity care: starting and increasing all recommended heart-failure medications as quickly as possible and monitoring patients closely during the first weeks after discharge.
• Usual care: medications are started and adjusted gradually, according to the judgment of the treating cardiologist and the patient's usual care team.

The study will follow participants for 12 months to see whether the high-intensity strategy reduces death, hospital readmission for heart failure, or worsening symptoms. It will also evaluate side effects, medication tolerance, and quality of life.

Participants will be randomly assigned to one of the two groups, attend regular follow-up visits for one year, complete a short quality-of-life questionnaire (EQ-5D).

This study will include about 360 women from 13 hospitals in Italy. It is sponsored by IRCCS Policlinico San Donato and funded by the Italian Medicines Agency (AIFA).

Full description

PopS-HF is a phase IV, low-interventional, multicenter randomized controlled trial designed to test whether intensive optimization of guideline directed medical therapy (GDMT), following the STRONG-HF (Safety, Tolerability and Efficacy of Rapid Optimization, Helped by NT-proBNP Testing of Heart Failure Therapies) titration strategy, improves outcomes in women hospitalized for heart failure (HF).

The study also includes a retrospective analysis of national healthcare databases and specialized HF registries from 2018-2023 to evaluate how GDMT are prescribed in real-world practice and to identify sex-related differences in treatment patterns and outcomes.

Eligible patients are women aged 18-85 years hospitalized for acute HF with evidence of congestion and hemodynamic stability before discharge. Exclusion criteria include severe comorbidities, pregnancy, and inability to follow up.

The prospective component randomizes 368 patients to an intensive strategy or usual care, with follow-up visits at 2, 4, 6, 12, 24, 36, and 52 weeks.

The primary endpoint is a composite of all-cause mortality, HF readmission, or worsening HF within 1 year.

Secondary endpoints assess optimization of therapy, side effects, biomarkers (NT-proBNP), and quality of life.

Enrollment: 368 estimated patients

Sex: Female

Ages: 18 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Female patients >18 <85 years.

2. Hospital admission within the 72 hours prior to Screening for acute heart failure with dyspnea at rest and pulmonary congestion on chest X-ray, and other signs and/or symptoms of heart failure such as edema and/or positive rales on auscultation.

3. All measures within 24 hours prior to Randomization of systolic blood pressure ≥ 100 mmHg, and of heart rate ≥ 60 bpm.

4. All measures within 24 hours prior to Randomization of serum potassium ≤ 5.0 mEq/L (mmol/L).

5. Biomarker criteria for persistent congestion:

   5.1. At Screening, NT-proBNP >1,800 pg/mL (2,350 pg/mL in case of atrial fibrillation) 5.2. At the time of Randomization (1-2 days prior to discharge), NT-proBNP >1,000 pg/mL (1,300 pg/mL in case of Atrial Fibrillation) to ensure the persistence of congestion and the acuity of the index episode).

6. At 1 week prior to admission, at Screening, and at Visit 2 6.1. If EF<50% (ie HFrEF or HFmrEF) either <½ the optimal dose of ACEi/ARB/ARNi and MRA and BB or no SGLT2i (see Table) must have been prescribed 6.2. If EF>50% (ie HFpEF): <½ the optimal dose of MRA (see Table) or no SGLT2i.

7. Written informed consent to participate in the study.

Exclusion criteria

1. Male patients
2. Age < 18 or > 85 years.
3. Mechanical ventilation (not including CPAP/BIPAP) in the 24 hours prior to Screening.
4. Significant pulmonary disease contributing substantially to the patients' dyspnoea such as FEV1 <1 liter or need for chronic systemic or nonsystemic steroid therapy, or any kind of primary right heart failure such as primary pulmonary hypertension or recurrent pulmonary embolism.

---

368 participants in 2 patient groups

Usual care

No Intervention group

Description:

Participants in the usual care arm will receive sequential introduction and adjustment of guideline-directed medical therapy (GDMT) according to the treating cardiologist or general physician's clinical judgment, following routine practice. Follow-up will occur at weeks 6, 12, 24, 36, and 52 after randomization, with clinical visits and intermediate phone contacts as per standard care.

High-intensity care

Experimental group

Description:

Participants assigned to the high-intensity arm will begin rapid initiation and optimization of guideline-directed medical therapy (GDMT) according to the STRONG-HF protocol. During hospitalization, eligible therapies (beta-blockers (BB), Angiotensin converting enzyme inhibitor(ACEi) /Angiotensin II receptor blocker (ARB)/Angiotensin Receptor-Neprilysin Inhibitors(ARNI), Mineralocorticoid Receptor Antagonists (MRA), and Sodium-Glucose Co-Transporter inhibitor 2 (SGLT2i) for HFrEF/HFmrEF; MRA and SGLT2i for HFpEF will be prescribed at least at half of the recommended target dose. Further titration toward full optimal doses will be performed within the first 6 weeks if clinically appropriate. Participants will undergo clinical assessments at weeks 2, 4, 6, 12, 24, 36, and 52, with safety monitoring including vital signs, physical examination, and laboratory evaluation (NT-proBNP, electrolytes, kidney function). Additional visits may occur after any up-titration if needed for safety.
