Abstract

We aimed to explore the predictive values of stress hyperglycaemia (SHG) and glycosylated haemoglobin (HbA1c) levels on admission for long-term recovery of cardiac function in patients with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PPCI). A total of 210 AMI patients were randomly selected. The levels of SHG and HbA1c were measured on admission, and all patients were treated with PPCI and followed up for one year. According to the recovery status of cardiac function during follow up, the patients were divided into a good recovery group and a poor recovery group. At one year after treatment, there were statistically significant differences in the levels of SHG (6.75 ± 0.69 vs 7.81 ± 0.92 mmol/l) and HbA1c (5.13 ± 0.25 vs 5.91 ± 0.39%) between the good and poor recovery groups (p < 0.05). The levels of SHG and HbA1c were associated with long-term recovery of cardiac function (p < 0.05). The receiver operating characteristic curves were plotted, and the area under the curves of SHG and HbA1c for predicting the long-term recovery of cardiac function were > 0.70. The levels of SHG and HbA1c were closely associated with longterm recovery of cardiac function after PPCI in AMI patients, displaying high predictive values.
