Therapy with ticagrelor for ST-elevated acute coronary syndrome accompanied by diabetes mellitus

To investigate the protective effect of ticagrelor on the myocardium of patients with ST-elevated acute coronary syndrome accompanied by diabetes mellitus.210 patients with diabetes mellitus receiving emergency percutaneous coronary intervention (PCI) due to ST-elevated acute coronary syndrome from December 2014 to June 2018 in the Hospital were selected and randomly divided into ticagrelor group and clopidogrel group. The myocardial microcirculation perfusion was evaluated via ST-segment elevation resolution (STR) in electrocardiogram (ECG) and myocardial blush grade (MBG). Myocardial necrosis markers, including creatine kinase (CK), CK-MB, and cardiac troponin I (cTnI), were evaluated. Moreover, the cardiac function was assessed using brain natriuretic peptide (BNP) level and left ventricular ejection fraction (LVEF). Finally, patients were followed up for one month on average, and the adverse cardiovascular and bleeding events were recorded.The results showed that CK, CK-MB, cTnI, and BNP levels in ticagrelor group were lower than those in clopidogrel group, and the differences were statistically significant (p0.05). Thrombolysis in myocardial infarction (TIMI) flow grading after the operation had no statistically significant difference between the two groups, and the usage rate of tirofiban in ticagrelor group was lower than that in clopidogrel group (p0.05). Besides, the myocardial microcirculation perfusion level after the operation in ticagrelor group was significantly higher than that in clopidogrel group. The proportions of STR ≥50% in ECG and MBG2 in ticagrelor group were significantly higher than those in clopidogrel group (p0.01). The incidence rate of mild bleeding in ticagrelor group was higher than that in clopidogrel group (p0.05).The application of ticagrelor in the treatment of ST-elevated acute coronary syndrome accompanied by diabetes mellitus can increase the level of myocardial microcirculation perfusion and improve the left heart function.
