This challenge is compounded by the healthcare overload following the COVID-19 pandemic, particularly in primary care (PC). Early diagnosis of HF is critical for improving outcomes, reducing complications, and optimizing resource use. However, there is no robust scientific evidence supporting the effectiveness of early screening for HF in PC settings.\n\nThis study aims to evaluate whether an early cardiology assessment model for patients with suspected HF and elevated NT-proBNP levels (\\>300 pg\u002FmL) improves clinical outcomes compared to the standard referral pathway. The hypothesis is that early intervention will reduce emergency visits, hospitalizations, and mortality related to HF.\n\nThis is a prospective, single-center, open-label, phase II randomized controlled trial with parallel group allocation (1:1). Patients presenting to PC with HF symptoms and no prior HF diagnosis, who have NT-proBNP levels \\>300 pg\u002FmL, will be invited to participate. After informed consent, participants will be randomized to one of two groups:\n\n* Intervention group: Early cardiology assessment within 7 days.\n* Control group: Standard referral by PC physician per usual care.\n\nRandomization will be computer-generated and managed independently to ensure allocation concealment. Patients will be followed for 12 months from the date of NT-proBNP testing. Outcomes will be collected through both cardiology and PC visits.\n\nOur primary outcome measure will be the clinical benefit, defined as a hierarchical composite endpoint of:\n\n1. Cardiovascular mortality\n2. All-cause mortality\n3. Number of hospitalizations due to HF\n4. Number of urgent care visits due to HF\n5. Number of GDMT (Guideline-Directed Medical Therapy) drugs initiated\n6. Number of GDMT drugs with dose escalation\n7. Proportional change in log (NT-proBNP) at 12 months\n\nThe primary analysis will use a win ratio methodology to maximize statistical efficiency and clinical interpretability.\n\nSecondary outcomes include:\n\n* Each component of the primary endpoint\n* Stratified analysis by confirmed or excluded HF diagnosis\n* Stratified analysis by HF phenotype (HFrEF vs HFpEF)\n* Stratified analysis by sex\n\nA sample size of 304 patients (152 per group) has been calculated to detect a win ratio of 1.7 with 80% power, based on expected clinical benefit and statistical assumptions from prior literature. The study is expected to complete recruitment within 12 months, with a total study duration of 24 months including follow-up and data analysis.",[50],"Heart Failure",[50,52,53,54,55],"Primary Care","Cardiology","NT-proBNP","proBNP","NOT_YET_RECRUITING","2025-07-07",{"date":59,"type":60},"2025-07-10","ACTUAL",{"date":62,"type":44},"2025-09",{"date":64,"type":44},"2027-12",{"name":5,"class":6}]
