Abstract

The aim of this study was to analyze the correlation between left ventricular mass index (LVMI) and the prognosis of patients with acute myocardial infarction (AMI).The study retrospectively analyzed the Registry of New-onset Atrial Fibrillation Complicating Acute Myocardial Infarction-Shanghai database and included 1957 patients with AMI who were hospitalized from February 2014 to March 2018, with a median follow-up of 2.7 ± 1.3 years; it calculated the number of all-cause mortalities after AMI. Through receiver operating characteristic curve analysis of LVMI, the optimal LVMI cutoff value was obtained, and the enrolled patients were grouped accordingly. The effects of different LVMI levels on the occurrence of cardiovascular and cerebrovascular adverse events were evaluated in patients with AMI. In addition, the risk assessment and prognostic value of the combined application of LVMI and the GRACE score was explored in patients with AMI.The incidences of all-cause mortality, cardiovascular death, heart failure readmission rate, and reinfarction in patients with AMI in LVMI ≥ 98.90 group were significantly higher than those in LVMI < 98.90 group (P< 0.05). The value of LVMI combined with the GRACE score in predicting the risk of post-AMI all-cause mortality as well as cardiovascular death seemed to be better than that of using the GRACE score alone. LVMI, old age, male sex, renal insufficiency, previous heart failure, stroke history, and decreased left ventricular ejection fraction were independent risk factors for all-cause mortality after AMI.High LVMI may be closely associated with all-cause mortality and adverse cardiovascular events after AMI, especially in patients with AMI with LVMI > 98.9. The risk of all-cause mortality after AMI can also be assessed in combination with LVMI and GRACE scores.

左心室质量指数对急性心肌梗死患者临床预后的影响
本研究的目的是分析左心室质量指数(LVMI)与急性心肌梗死(AMI)患者预后的相关性。本研究回顾性分析上海新发心房颤动合并急性心肌梗死数据库,纳入了2014年2月至2018年3月住院的1957例AMI患者,中位随访时间为2.7±1.3年;它计算了AMI后的全因死亡率。通过LVMI受者工作特征曲线分析,获得最佳LVMI截断值,并对入组患者进行分组。观察不同LVMI水平对AMI患者心脑血管不良事件发生的影响。此外,探讨LVMI与GRACE评分联合应用在AMI患者中的风险评估及预后价值。LVMI≥98.90组AMI患者的全因死亡率、心血管死亡、心力衰竭再入院率、再梗死发生率均显著高于LVMI < 98.90组(P< 0.05)。LVMI联合GRACE评分在预测ami后全因死亡率和心血管死亡风险方面的价值似乎优于单独使用GRACE评分。LVMI、年龄、男性、肾功能不全、既往心力衰竭、卒中史、左室射血分数降低是AMI后全因死亡率的独立危险因素。高LVMI可能与AMI后的全因死亡率和不良心血管事件密切相关,尤其是LVMI为bb0 98.9的AMI患者。AMI后的全因死亡风险也可以结合LVMI和GRACE评分进行评估。
