The understanding of ANP\u2019s role in cardiac systems has improved considerably in recent decades. This review focuses on several studies demonstrating the importance of analyzing the regulations between the endocrine and mechanical function of the heart and emphasizes the effect of ANP, as the primary hormone of the atria, on atrial fibrillation (AF) and related diseases. The review first discusses the available data on the diagnostic and therapeutic applications of ANP and then explains effect of ANP on heart failure (HF) and atrial fibrillation (AF) and vice versa, where tracking ANP levels could lead to understanding the pathophysiological mechanisms operating in these diseases. Second, it focuses on conventional treatments for AF, such as cardioversion and catheter ablation, and their effects on cardiac endocrine and mechanical function. Finally, it provides a point of view about the delayed recovery of cardiac mechanical and endocrine function after cardioversion, which can contribute to the occurrence of acute heart failure, and the potential impact of restoration of the sinus rhythm by extensive ablation or surgery in losing ANP-producing sites. Overall, ANP plays a key role in heart failure through its effects on vasodilation and natriuresis, leading to a decrease in the activity of the renin-angiotensin-aldosterone system, but it is crucial to understand the intimate role of ANP in HF and AF to improve their diagnosis and personalizing the patients\u2019 treatment.<\/jats:p>","DOI":"10.3390\/ijms24076470","type":"journal-article","created":{"date-parts":[[2023,3,30]],"date-time":"2023-03-30T02:23:46Z","timestamp":1680143026000},"page":"6470","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Atrial Natriuretic Peptides as a Bridge between Atrial Fibrillation, Heart Failure, and Amyloidosis of the Atria"],"prefix":"10.3390","volume":"24","author":[{"given":"Farzad","family":"Rahbar Kouibaran","sequence":"first","affiliation":[{"name":"Department of Medical and Surgical Sciences, University of Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Sabatino","sequence":"additional","affiliation":[{"name":"Unit of Heart Failure and Transplantation, IRCCS Azienda Ospedaliero-Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Barozzi","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences, University of Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3823-3809","authenticated-orcid":false,"given":"Igor","family":"Diemberger","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences, University of Bologna, 40138 Bologna, Italy"},{"name":"Unit of Cardiology, IRCCS Azienda Ospedaliero-Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,30]]},"reference":[{"key":"ref_1","unstructured":"Singh, A., and Williams, G.H.
