This study investigated the prognostic significance and diagnostic value of RWMA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Echocardiographies of 1110 consecutive NSTEMI patients undergoing coronary angiography were analyzed. Patients were classified as type 1 NSTEMI if an atherosclerotic culprit lesion was identified, otherwise as type 2. Adverse in-hospital events were a composite of in-hospital death, cardiogenic shock, and mechanical ventilation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 895 patients with type 1 NSTEMI and 215 with type 2, RWMA were present in 68.2% overall. Adverse in-hospital events occurred in 18.1% of patients with RWMA versus 10.5% without (OR 1.89, 95% CI 1.29\u20132.81). Mediation analysis showed this excess risk was largely attributable to reduced ejection fraction. RWMA occurred more frequently in type 1 compared with type 2 NSTEMI (70.3% vs. 59.5%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003) and remained an independent predictor of type 1 NSTEMI (OR 1.69,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002). However, the diagnostic accuracy of RWMA alone was modest (AUC 0.554), improving to fair performance (AUC 0.727) when combined with clinical factors. Among type 1 NSTEMI patients, RWMA corresponded to the culprit lesion territory in 90.1% when present.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>RWMA identify NSTEMI patients at higher risk of adverse outcomes. Although insufficient alone to differentiate type 1 from type 2 NSTEMI, RWMA augment diagnostic accuracy when combined with clinical factors.
