Blood glucose changes in diabetes mellitus patients with acute myocardial infarction and its influence on heart function / 中国医师进修杂志

ABSTRACT

ObjectiveTo explore the blood glucose changes in diabetes mellitus (DM) patients with acute myocardial infarction(AMI) and its influence on heart function.MethodsSeventy-three patients with AMI were divided into DM group (35 cases) with DM and non-DM group (38 cases) without DM.The blood glucose changes and the relationships with heart functon were observed in two groups.ResultsIn DM group,33 cases(94.29％,33/35) had high fasting blood glucose,whereas in the non-DM group,14 cases(36.84％,14/38) had stress hyperglycemia.The levels of fasting blood glucose and glycosylated hemoglobin in the DM group were significantly higher than those in the non-DM group [(9.7 ± 2.4) mmol/L vs.(5.8 ± 2.3) mmol/L,(10.13 ±1.95 )％ vs.(7.22 ± 1.87)％,P ＜ 0.05 ].The levels of creatine kinase isozyme MB (CK-MB) and troponin T (TnT) in the DM group were significantly higher than those in the non-DM group [ ( 217 ± 53 ) U/L vs.( 119 ± 47 ) U/L,( 6.2 ± 3.7 ) mg/L vs.( 3.4 ± 2.9 ) mg/L,P ＜ 0.05 ].The detection of left ventricular function after 4 weeks of AMI showed that left ventricular end diastolic volume (EDV) and end systolic volume (ESV) of the DM group were significantly higher and LVEF was significantly lower than those of the non-DM group [ (81.7 ± 10.8 ) ml vs.(74.9 ± 10.2 ) ml,(47.6 ± 10.7 ) ml vs.(39.8 ±12.6) ml,(41.7 ± 4.8)％ vs.(48.9 ± 8.5)％,P＜ 0.05 ].ConclusionsPatients with AMI and DM have high hyperglycemia and worse heart function.Therefore,intervention measures should be performed for these patients.
