Chronic hyperglycaemia, assessed by elevated glycated haemoglobin (A1C), is a known risk factor for heart failure (HF) and cardiovascular (CV) death among subjects with diabetes. Whether this risk varies with left ventricular ejection fraction (LVEF) is unknown. This study evaluated whether A1C influences a composite outcome of either HF hospitalization or CV death differently along the spectrum of LVEF.

2型糖尿病和最近的急性冠状动脉综合征患者的高血糖，射血分数和心力衰竭或心血管死亡的风险。

通过升高的糖化血红蛋白（A1C）评估的慢性高血糖症，是糖尿病患者心衰（HF）和心血管（CV）死亡的已知危险因素。这种风险是否随左心室射血分数（LVEF）的变化尚不清楚。这项研究评估了A1C是否会影响LV住院范围内的HF住院或CV死亡的综合结果。
