A consensus or society position rather than new primary data.
This narrative review synthesizes scientific and educational literature to propose an anatomy-anchored framework for integrating the heart's endocrine function—specifically natriuretic peptide physiology—into pre-clerkship medical curricula. The authors argue that linking cardiac structure to ANP and BNP/NT-proBNP secretion can strengthen structure-function reasoning and clinical decision-making, but provide no empirical evidence that such integration improves learning outcomes or clinical competency.
Narrative literature review. Literature on cardiac endocrine function, natriuretic peptide physiology, and medical education integration; not a study of actual medical students or curricula.
Discovery of ANP, BNP, and CNP in the 1980s established the heart as an endocrine organ regulating blood pressure, renal function, and extracellular volume Medical education literature provides limited explicit guidance on integrating cardiac endocrine function into early curricula ANP links atrial structure and stretch to volume regulation; BNP/NT-proBNP links ventricular wall stress to heart failure evaluation
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
This work recommends curricular change but provides no empirical evidence that cardiac endocrine integration improves student understanding, clinical reasoning, or patient outcomes. Educators may consider the proposed framework conceptually sound, but adoption should be piloted and evaluated with learner outcome measures.

Background. The heart is commonly introduced in early medical education through its structural, mechanical, and electrophysiological roles. Although this framing remains foundational, it may underemphasize the heart's endocrine functions. Cardiac endocrine signaling, particularly natriuretic peptide physiology, offers a concise structure-function example linking anatomy, histology, cardiovascular physiology, and clinical biomarker interpretation.Objective. To synthesize scientific and educational principles of cardiac endocrine function and propose an anatomy-anchored framework for integration into pre-clerkship medical education.Methods. A librarian-assisted narrative review was conducted in May 2025 using representative literature from PubMed, Google Scholar, and Scopus, supplemented by historical, molecular, physiological, anatomical, and medical education sources. The search focused on cardiac endocrine function, natriuretic peptides, and medical education and yielded 23 abstracts. The aim was conceptual synthesis rather than systematic or exhaustive retrieval.Results. The discovery of atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) established the heart as an endocrine organ influencing renal, and cardiovascular homeostasis. The available medical education literature provides limited explicit guidance on how this topic should be introduced, and reinforced in early curricula. Integration of cardiac endocrine biology aligns with principles of cognitive integration, spiral curriculum design, and authentic learning. ANP and BNP/NT-proBNP are proposed as high-yield teaching examples: ANP links atrial structure and stretch to volume regulation, whereas BNP/NT-proBNP links ventricular wall stress to heart failure evaluation.Conclusions. Early integration of the heart's endocrine function into medical curricula may fortify structure-function reasoning, enhance systems thinking, and support mechanistic clinical reasoning. Rather than adding a separate curricular block, cardiac endocrine signaling can be incorporated through anatomy and histology, then reinforced in cardiovascular physiology, renal physiology, biochemistry, pharmacology, and clinical reasoning. Aligning foundational instruction with modern cardiovascular science can improve learners' conceptual frameworks and better prepare them for clinical decision making.
