However, the associations between LVEDD, pre-admission risk factors, admission biochemical markers, and medication use warrant further investigation. The prognostic impact of LVEDD evaluation within 24 hours of admission in STEMI patients has not been extensively studied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed the association between LVEDD measurements within 24 hours of admission and a composite endpoint of cardiovascular events and mortality in 664 STEMI patients undergoing percutaneous coronary intervention (PCI).
