Comparison between type-2 and type-1 myocardial infarction：clinical features, treatment strategies and outcomes

ObjectiveTo 与尖锐心肌的梗塞(AMI ).MethodsWe 包括了的 type-2 对 type-1 在病人在发生，临床的特征，当前的治疗策略和结果估计差别有 type-1 或 type-2 AMI 的诊断的 824 个连续病人。在索引住院期间，临床的特征和治疗策略详细被收集。在 1 年的后续，死亡，击，流血的非致命的心肌的梗塞和专业是 recorded.ResultsType-1 AMI 在 707 是在场的(86%) 盒子当(14%) 117 作为 type-2 被分类时。有 type-2 AMI 的病人更经常是象糖尿病那样的女、有的更高的合作病态，以前的非圣片断举起急性冠的症候群，损害肾的功能，贫血症， atrial 纤维性颤动和恶意。然而，保存了左室的喷射部分，正常冠的动脉是经常看见的更多，侵略治疗是不太普通的，并且反血小板药， statins 和 beta-blockers 是在有 type-2 AMI 的病人规定的更少。在 1 年的后续， type-2 AMI 与更高粗略的死亡风险被联系(HR：1.75， 95% CI：1.14-2.68；P = 0.001 ) ，但是这个协会没在 multivariable 调整以后仍然保持重要(P = 0.785 ) 。而且，我们没发现 type-2 AMI 与另外的临床的 outcomes.ConclusionsIn 被联系这张真实人口与 type-1 相比， type-2 AMI 是主要女人们并且有更多的合作病态。侵略治疗策略和 cardioprotective 药是在 type-2 使用的更少，当 1 年的临床的结果是类似的时。

Objective To assess the differences in incidence, clinical features, current treatment strategies and outcome in patients with type-2vs. type-1 acute myocardial infarction （AMI）.Methods We included 824 consecutive patients with a diagnosis of type-1 or type-2 AMI. Dur-ing index hospitalization, clinical features and treatment strategies were collected in detail. At 1-year follow-up, mortality, stroke, non-fatal myocardial infarction and major bleeding were recorded.ResultsType-1 AMI was present in 707 （86%） of the cases while 117 （14%） were classified as type-2. Patients with type-2 AMI were more frequently female and had higher co-morbidities such as diabetes, previous non-ST segment elevation acute coronary syndromes, impaired renal function, anaemia, atrial fibrillation and malignancy. However, preserved left ventricular ejection fraction and normal coronary arteries were more frequently seen, an invasive treatment was less common, and anti-platelet medications, statins and beta-blockers were less prescribed in patients with type-2 AMI. At 1-year follow-up, type-2 AMI was associated with a higher crude mortality risk （HR： 1.75, 95% CI： 1.14-2.68;P = 0.001）, but this association did not remain significant after multivariable adjustment （P = 0.785）. Furthermore, we did not find type-2 AMI to be associated with other clinical outcomes.Conclusions In this real-life population, compared with type-1, type-2 AMI were predominantly women and had more co-morbidities. Invasive treatment strategies and cardioprotective medications were less used in type-2, while the 1-year clinical outcomes were similar.
