Clinical features, angiographic findings, management, and outcomes of SCAD patients who present reduced left ventricular ejection fraction (LVEF) remain unknown.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>The Spanish multicentre prospective SCAD registry (NCT03607981), included 389 consecutive patients with SCAD. In 348 of these patients, LVEF could be assessed by echocardiography during the index admission. Characteristics and outcomes of patients with preserved LVEF (LVEF \u226550%, n = 295, 85%) were compared with those with reduced LVEF (LVEF &amp;lt;50%, n = 53, 15%). Mean age was 54 years and 90% of patients in both groups were women. The most frequent clinical presentation in patients with reduced LVEF was ST-segment elevation myocardial infarction (STEMI) (62% vs. 36%, P &amp;lt; 0.001), especially anterior STEMI. Proximal coronary segment and multi-segment involvement were also significantly more frequent in these patients. No differences were found on initial revascularization between groups. Patients with reduced LVEF significantly received more often neurohormonal antagonist therapy, and less frequently aspirin. In-hospital events were more frequent in these patients (13% vs. 5%, P = 0.01), with higher rates of death, cardiogenic shock, ventricular arrhythmia, and stroke. During a median follow-up of 28 months, the occurrence of a combined adverse event did not statistically differ between the two groups (19% vs. 12%, P = 0.13). However, patients with reduced LVEF had higher mortality (9% vs. 0.7%, P &amp;lt; 0.001) and readmission rates for heart failure (HF) (4% vs. 0.3%, P = 0.01).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Patients with SCAD and reduced LVEF show differences in clinical characteristics and angiographic findings compared with SCAD patients with preserved LVEF.
