Eligibility criteria were age above 65 years, permanent cardiac pacemaker and competent to give informed consent. Patients underwent echocardiography at the pacemaker visit and were referred to 99mTc-DPD-scintigraphy (DPD) and blood samples if septum thickness was \u226512 mm, defined as left ventricular hypertrophy (LVH). Fifty eight of the 128 patients had LVH on echocardiography. Eleven patients had a DPD-scintigraphy based diagnosis of ATTR-CM, which represent 19% of patients with LVH and 9% of the total cohort. Patients diagnosed with ATTR-CM had higher concentrations of cardiac biomarkers (P &amp;lt; 0.001), higher E\/E\u2032 (P = 0.001), and lower global longitudinal strain (P = 0.003) on echocardiography and more heart failure symptoms (P = 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The prevalence of ATTR-CM in elderly patients with PM and LVH on echocardiography was 19%.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ehf2.14645","type":"journal-article","created":{"date-parts":[[2024,1,11]],"date-time":"2024-01-11T02:10:50Z","timestamp":1704939050000},"page":"871-876","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Prevalence of Transthyretin Amyloid Cardiomyopathy in Pacemaker Patients"],"prefix":"10.1093","volume":"11","author":[{"given":"Eirik","family":"Aaseth","sequence":"first","affiliation":[{"name":"Department of Medicine, Innlandet Hospital Trust , Elverum ,","place":["Norway"]},{"name":"Department of Cardiology, Oslo University Hospital Ulleval , Oslo ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jon R.","family":"Christiansen","sequence":"additional","affiliation":[{"name":"Department of Medicine, Innlandet Hospital Trust , Elverum ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,1,10]]},"reference":[{"key":"2026012113160003500_ehf214645-bib-0001","doi-asserted-by":"publisher","first-page":"1203","DOI":"10.1161\/CIRCULATIONAHA.108.843334","article-title":"Systemic cardiac amyloidoses: Disease profiles and clinical courses of the 3 main types","volume":"120","author":"Rapezzi","year":"2009","journal-title":"Circulation"},{"key":"2026012113160003500_ehf214645-bib-0002","doi-asserted-by":"publisher","first-page":"512","DOI":"10.1002\/ejhf.2140","article-title":"Diagnosis and treatment of cardiac amyloidosis.
