Left atrial reservoir strain (LASr) is correlated with LV filling pressures and may serve as an alternative parameter in these patients. The aim of this study was to determine whether LASr can be used to estimate LAP in HFrEF patients in whom E\/A ratio is not available.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>Echocardiograms of chronic HFrEF patients were analysed and LASr was assessed with speckle tracking echocardiography. LAP was estimated using the current ASE\/EACVI algorithm. Patients were divided into those in whom LAP could be estimated using this algorithm (LAPe) and into those in whom this was not possible because E\/A ratio was not available (LAPne). We assessed the prognostic value of LASr on the primary endpoint (PEP), which comprised the composite of hospitalization for the management of acute or worsened HF, left ventricular assist device implantation, cardiac transplantation, and cardiovascular death, whichever occurred first in time. We studied 153 patients with a mean age of 58 years of whom 76% men and 82% who were in NYHA class I-II. A total of 86 were in the LAPe group and 67 in the LAPne group. LASr was significantly lower in the LAPne group as compared with the LAPe group (15.8% vs. 23.8%, P &amp;lt; 0.001). PEP-free survival at a median follow-up of 2.5 years was 78% in LAPe versus 51% in LAPne patients. An increase in LASr was significantly associated with a reduced risk of the PEP in LAPne patients (adjusted hazard ratio: 0.91 per %, 95% confidence interval 0.84\u20130.98). An abnormal LASr (&amp;lt;18%) was associated with a five-fold increase in reaching the PEP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In HFrEF patients in whom echocardiographic estimation of LAP is not possible due to due to unavailability of E\/A ratio, assessing LASr potentially carries added clinical and prognostic value.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ehf2.14372","type":"journal-article","created":{"date-parts":[[2023,5,9]],"date-time":"2023-05-09T02:45:48Z","timestamp":1683600348000},"page":"2345-2353","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Potential Role of Left Atrial Strain in Estimation of Left Atrial Pressure in Patients with Chronic Heart Failure"],"prefix":"10.1093","volume":"10","author":[{"given":"Yaar S.","family":"Aga","sequence":"first","affiliation":[{"name":"Department of Cardiology, Thoraxcenter, Erasmus University Medical Center , Rotterdam ,","place":["The Netherlands"]},{"name":"Department of Cardiology, Franciscus Gasthuis & Vlietland , Rotterdam ,","place":["The Netherlands"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabrina","family":"Abou Kamar","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Thoraxcenter, Erasmus University Medical Center , Rotterdam ,","place":["The Netherlands"]},{"name":"Department of Cardiology, Franciscus Gasthuis & Vlietland , Rotterdam ,","place":["The Netherlands"]},{"name":"The Netherlands Heart Institute , Utrecht ,","place":["The Netherlands"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie Fen","family":"Chin","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Thoraxcenter, Erasmus University Medical Center , Rotterdam ,","place":["The Netherlands"]},{"name":"Department of Cardiology, Franciscus Gasthuis & Vlietland , Rotterdam ,","place":["The Netherlands"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor.
