To compare short- and long-term survival in patients admitted to hospital after acute myocardial infarction (AMI) with and without out-of-hospital cardiac arrest (OHCA).
Prospective cohort study of all AMI patients admitted to Oslo University Hospital Ulleval from September 1, 2005 to December 31, 2011. All-cause mortality was obtained from the Norwegian Cause of Death Registry with censoring date December 31, 2013. Cumulative survival was assessed with the Kaplan-Meier and the Life-table method. Logistic- and Cox regression were used for risk comparisons.
We identified 404 AMI patients with OHCA and 9425 AMI patients without. AMI patients without OHCA were categorized as ST-elevation myocardial infarction (STEMI, n=4522) or non-STEMI (NSTEMI, n=4903). Mean age was 63.6±standard deviation (SD) 12.5, 63.8±13.1 and 69.7±13.6 years in OHCA, STEMI and NSTEMI, respectively. Coronary angiography with subsequent percutaneous coronary intervention if indicated, was performed in 87% of OHCA, 97% of STEMI and 80% of NSTEMI patients. Thirty-day survival was 63%, 94% and 94%, and 8-year survival was 49%, 74%, and 57%, respectively. Among patients surviving the first 30days, no significant difference in risk during long-term follow-up was found (adjusted Hazard Ratio (aHR) 1.15 [95% CI 0.82-1.60], aHR 0.89 [95% CI 0.64-1.24]).
Long-term survival after OHCA due to AMI was good, with 49% of admitted patients being alive after eight years. Although short-term mortality remained high, OHCA patients alive after 30days had similar long-term risk as AMI patients without OHCA.
比较因急性心肌梗死（AMI）入院的伴有和不伴有院外心脏骤停（OHCA）患者的短期和长期生存情况。
对 2005 年 9 月 1 日至 2011 年 12 月 31 日期间入住奥斯陆大学医院 Ulleval 的所有 AMI 患者进行前瞻性队列研究。所有原因的死亡率均从挪威死因登记处获得，并于 2013 年 12 月 31 日截止。使用 Kaplan-Meier 和寿命表法评估累积生存率。使用逻辑回归和 Cox 回归进行风险比较。
我们确定了 404 例伴有 OHCA 的 AMI 患者和 9425 例不伴有 OHCA 的 AMI 患者。不伴有 OHCA 的 AMI 患者分为 ST 段抬高型心肌梗死（STEMI，n=4522）或非 ST 段抬高型心肌梗死（NSTEMI，n=4903）。OHCA、STEMI 和 NSTEMI 患者的平均年龄分别为 63.6±12.5 岁、63.8±13.1 岁和 69.7±13.6 岁。如果有指征，对 87%的 OHCA、97%的 STEMI 和 80%的 NSTEMI 患者进行了冠状动脉造影术和随后的经皮冠状动脉介入治疗。30 天生存率分别为 63%、94%和 94%，8 年生存率分别为 49%、74%和 57%。在存活 30 天的患者中，在长期随访期间未发现风险存在显著差异（调整后的危险比[aHR]1.15[95%置信区间 0.82-1.60]，aHR 0.89[95%置信区间 0.64-1.24]）。
AMI 所致 OHCA 后的长期生存率良好，8 年后有 49%的入院患者存活。尽管短期死亡率仍然很高，但存活 30 天后的 OHCA 患者与不伴有 OHCA 的 AMI 患者具有相似的长期风险。
