ABSTRACT
BACKGROUND: Only a few information is available on the risk of stress hyperglycemia following acute myocardial infarction after statin use. We investigate the association of stress-induced hyperglycemia following statin use in patients with acute myocardial infarction. METHODS: An observational analysis of 476 consecutive patients who suffered acute myocardial infarction was carried out. All selected patients were divided into diabetes mellitus and non-diabetes based on the presence or absence of diabetes. The cardiac incidence of in-hospital and stress-induced hyperglycemia was recorded. RESULTS: Among patients with stress hyperglycemia in non-diabetes mellitus subgroups, the average fasting plasma glucose values in statin users were higher than in non-statin users (P < 0.05). But in diabetes mellitus subgroups, the average fasting plasma glucose did not have a significant difference between statin users and non-statin users (P > 0.05). In non-diabetes mellitus patients, the incidence of stress hyperglycemia with statin therapy was significantly higher than with non-statin therapy (P = 0.003). But in diabetes mellitus patients group, there is no significant difference in incidence of stress hyperglycemia between patients with statin therapy and patients without statin therapy (P = 0.902).The incidence of heart failure and in-hospital mortality of acute myocardial infarction in patients with stress-induced hyperglycemia was significantly higher than in non-hyperglycemia patients (P < 0.05). CONCLUSION: Statins are related to higher stress hyperglycemia and cardiac incidences after acute myocardial infarction.
