Influence of glycaemia and HbA1C levels at admission of insulin-independent diabetes patients on the length and outcome of hospitalization due to NSTEMI/STEMI

Abstract

This study aims to examine the influence of admission glycaemia and glycosylated haemoglobin (HbA1C) levels on the length of hospitalization and its outcome in insulin-independent diabetes mellitus (DM) patients suffering from ST-Segment Elevation Myocardial Infarction (STEMI)/Non-STEMI (NSTEMI). This cross-sectional study included 103 subjects with a history of insulin-independent DM, currently hospitalized due to acute myocardial infarction (AMI). Out of 103 subjects, 59 (57%) were men and 66 (64.1%) of them suffered from STEMI. Mean age of study population was 67±9 years. The following parameters were monitored: demographic, coronary, cardiovascular and DM risk factors history, as well as laboratory, clinical, echocardiography and angiography parameters. DM mean duration was 7 (1-30) months, and it influenced the length of hospitalization (r=0.232, p<0.05), but not the outcome (r=0.174, p>0.05). Mean length of hospitalization was 8 and 8.5 days in STEMI and NSTEMI patients respectively, with no difference between groups (log-rank ch2= 0.476, p>0.05). HbA1C values influenced the length of hospitalization (r=0.213, p<0.05), opposite to admission glycaemia (r=0.148, p>0.05). Duration of DM and the level of HbA1C prolong the length of hospitalization, but do not influence the clinical outcome of AMI patients suffering from insulin-independent DM.
