Incidence, predictors and prognostic implications of dyspnea at admission among acute coronary syndrome patients without heart failure

Among patients with stable coronary artery disease, effort-related dyspnea is associated with a larger ischemic territory and worse outcome. Whether dyspnea, not related to heart failure, is also associated with adverse outcome among patients with acute coronary syndromes (ACS) has not been fully elucidated. We studied ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) during 2010–2013 who were classified as Killip 1. A retrospective comparative analysis was performed between patients with chest pain alone (n = 2017) and those with chest pain with dyspnea (n = 417). Patients with dyspnea were older (64.4 ± 13 vs.61.8 ± 12, p
