The primary outcome was SCD-equivalent life-threatening VAs (LTVAs) composed of true SCDs and SCDs aborted by successful resuscitation or appropriate implantable cardiac device (ICD) therapy. The risk of sudden LTVA was estimated with a multivariate subdistribution hazard model using other deaths as competing events. Two-hundred thirteen (n = 211, 2.6%) patients suffered acute phase VF\/VT leading to resuscitation and survived to discharge, and most occurred before angiography (80.6%, n = 170) and were VF (92.9%, n = 196). During a median follow-up of 7.6 years, 3.9% (n = 316) of all the patients had LTVA (10.0% in the VF\/VT group vs. 3.8% in other patients). Ventricular fibrillation\/VTs during ACS are associated with an increased risk for future SCD (hazard ratio 3.07; 95% confidence interval 1.94\u20134.85, P &amp;lt; 0.001). Most LTVAs occurred in patients without ICDs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
