Nogales-Romo MT, et al. - Researchers intended to ascertain the influence of coronary artery disease (CAD) in patients resuscitated from sudden cardiac arrest (SCA) with non-diagnostic electrocardiogram (ECG) by assessing the prevalence, distribution, extension, and prognostic value of CAD. Out of 545 patients resuscitated from SCA with at least one cardiac catheterization (CC) during hospitalization, 203 with a non-diagnostic ECG were included in the study. Post-discharge follow-up of 5 years was performed. A high prevalence of significant CAD was reported in these subjects. A CAD Prognostic Index of 0 and a SYNTAX score of 0 was detected in 78 (38.4%) patients. No different long-term prognosis was reported in association with SYNTAX score. A worse long-term prognosis was seen among patients with severe disease in the three main coronary vessels and patients with higher (≥56) CAD Prognostic Index Score.
