The novel Acute Myocardial Infarction (AMI) Risk Stratification (nARS) system was recently developed based on original criteria. The use of nARS may reduce the length of hospitalization.
We allocated 560 AMI patients into the pre-nARS group (before adopting nARS) or the nARS group. Patients in the nARS group were subdivided into the low (L), intermediate (I), and high (H) risk groups, whereas patients in the pre-nARS group were subdivided into the equivalent L (eL), equivalent I (eI), or equivalent H (eH) risk groups based on the nARS criteria. Length of coronary care unit (CCU) stay was significantly shorter in the nARS group (2.8±3.5 days) compared with the pre-nARS group (4.4±5.4 days; P<0.001). Length of hospital stay was also shorter in the nARS group (9.4±8.9 days) compared with the pre-nARS group (13.4±12.8 days; P<0.001). Length of CCU stay was significantly shorter in the L (1.1±1.0 days), I (2.8±3.5 days), and H (5.0±4.8 days) risk groups compared with corresponding eL (2.2±1.1 days), eI (4.4±5.4 days), and eH (7.1±7.8 days) risk groups.
Length of CCU and hospital stay were significantly shorter in the nARS group compared with the pre-nARS group. The use of nARS may save medical resources in the treatment of AMI in the regional health-care system.
新型急性心肌梗死（AMI）风险分层（nARS）系统是基于原始标准建立的。使用 nARS 可能会缩短住院时间。
我们将 560 例 AMI 患者分为 nARS 前组（采用 nARS 前）和 nARS 组。nARS 组患者分为低（L）、中（I）和高（H）风险组，而 nARS 前组患者则根据 nARS 标准分为等效低（eL）、等效 I（eI）或等效 H（eH）风险组。nARS 组患者的冠心病监护病房（CCU）住院时间明显短于 nARS 前组（分别为 2.8±3.5 天和 4.4±5.4 天；P<0.001）。nARS 组患者的住院时间也明显短于 nARS 前组（分别为 9.4±8.9 天和 13.4±12.8 天；P<0.001）。L（1.1±1.0 天）、I（2.8±3.5 天）和 H（5.0±4.8 天）风险组患者的 CCU 住院时间明显短于相应的 eL（2.2±1.1 天）、eI（4.4±5.4 天）和 eH（7.1±7.8 天）风险组。
与 nARS 前组相比，nARS 组患者的 CCU 和住院时间明显缩短。在区域医疗保健系统中治疗 AMI 时，使用 nARS 可能会节省医疗资源。
