Consecutive hypertensive patients undergoing PA screening at a single hospital between 2016 and 2024 while on RASIs were recruited. Plasma aldosterone concentration (PAC) and direct renin concentration (DRC) were measured at pre-washout, post-washout, and after captopril-challenge testing, with aldosterone-to-renin ratio (ARR) calculated. Among 412 analyzed patients, PA and essential hypertension showed significant differences in PAC, DRC, and ARR across all time points. Pre-washout ARR (cutpoint 2.69) achieved sensitivity 83.3%, specificity 87.2%, PPV 82.2%, and NPV 88.1%.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/screening-and-diagnosis-of-primary-aldosteronism-in-patients-using-renin-angiotensin-system-inhibitors-original-article/442117/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/screening-and-diagnosis-of-primary-aldosteronism-in-patients-using-renin-angiotensin-system-inhibitors-original-article/442117.png","ImageObject",300,407,{"name":42,"@type":43},"supergirl","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-09-29",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",12,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"Can patients undergoing screening for primary aldosteronism remain on renin-angiotensin system inhibitors?","Question",{"text":63,"@type":64},"Yes.

Consecutive patients with hypertension who underwent PA screening at our hospital between 2016 and 2024 while on RASIs were recruited. Plasma aldosterone concentration (PAC) and direct renin concentration (DRC) were measured at three time points: pre-washout, post-washout, and post-captopril-challenge test (CCT) . Subsequently, the aldosterone-to-renin ratio (ARR) was calculated, and PAC, DRC, and ARR were compared across time points. Receiver operating characteristic (ROC) curve analysis was performed to determine optimal diagnostic cutpoints. A total of 412 patients on RASIs, with or without calcium-channel blockers (CCBs) or α1-receptor antagonists, were analyzed. Among these, 175 had PA and 237 had essential hypertension (EH). PAC, DRC, and ARR were significantly different between the PA and EH groups across all three time points. Within the PA cohort, PAC (p \u003C 0.001) and ARR (p = 0.016) differed significantly between the pre-washout and post-CCT measurements, whereas DRC did not (p = 0.456). The optimal pre-washout ARR cutpoint of 2.69 demonstrated a sensitivity of 83.3%, specificity of 87.2%, positive predictive value (PPV) of 82.2%, and negative predictive value (NPV) of 88.1% for diagnosing PA. These findings indicate that pre-washout PAC, DRC, and ARR retain high diagnostic performance for PA in patients treated with RASIs, provided that other agents affecting the renin-angiotensin-aldosterone system are not co-administered.  \n1  Introduction  \nOver recent decades, accumulating evidence has revealed that under conditions of high sodium intake, excessive aldosterone exerts detrimental impacts on the cardiovascular system [1– 3] . These effects operate, at least in part, independently of blood pressure (BP) levels. Individuals diagnosed with primary aldosteronism (PA) face significantly elevated risk of  \ndeveloping cardiovascular, cerebrovascular, and renal complications compared with those with essential hypertension (EH), even when the BP levels and hypertension duration are comparable [4, 5] . The prevalence of PA among patients with hypertension ranges from approximately 5% in primary care settings to 10% in specialized hypertension referral centers [6] . Notably, despite the likelihood of PA exceeding 70% in hypertensive patients with severe hypokalemia, fewer than  \n\n| Abbreviations: ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin-receptor blocker; ARNI, angiotensin-receptor-neprilysin inhibitor; ARR, aldosterone-to-renin ratio; AUROC, area under the receiver operating characteristic curve; BP, blood pressure; CCB, calcium-channel blocker; CCT, captopril-challenge test; DBP, diastolic blood pressure; DHP-CCB, dihydropyridine calcium-channel blocker; DRC, direct renin concentration; EH, essential hypertension; ESG, Endocrine Society Guidelines; ESH, European Society of Hypertension; MRA, mineralocorticoid receptor antagonist; NDHP-CCB, non-dihydropyridine calcium-channel blocker; PA, primary aldosteronism; PAC, plasma aldosterone concentration; RAAS, re","cbCaiobNFZLF1Bk1","https://ap.wps.com/l/cbCaiobNFZLF1Bk1","pdf",2449640,11,"English","# Introduction\n## Background and clinical rationale\n# Methods and measurements\n## Patient recruitment and design\n## Hormone measurements and time points\n## ROC analysis and diagnostic cutpoints\n# Results\n## Differences between PA and essential hypertension\n## Performance of PAC, DRC, and ARR","[{\"question\":\"Can patients undergoing screening for primary aldosteronism remain on renin-angiotensin system inhibitors?\",\"answer\":\"Yes.
