| dc.description.abstract | Objective: To investigate the association of diabetes with ST segment resolution and clinical outcomes after fibrinolysis in patients with first ST elevation myocardial infarction (STEMI). Methods and results: Clinical information from 275 consecutive patients with first STEMI, who received streptokinase within 6 h of chest pain initiation, was collected prospectively. ST resolution >= 50%, 90 min after fibrinolysis, was considered as a sign of successful reperfusion. Association of diabetes with the risk of reperfusion failure, development of heart failure and in-hospital mortality was determined before and after controlling for other coronary risk factors. ST resolution >= 50% was present in 45.1% of non-diabetics and 48.7% of diabetics (p = 0.1). Heart failure and in-hospital mortality were more common in diabetics (25.7% vs. 14.8%, p = 0.03 and 17.8% vs. 8.4%, p = 0.03, respectively). Diabetics were more likely to have threevessel disease in coronary angiography (23% vs. 8%, p < 0.001). After controlling for baseline characteristics, diabetes was not independently associated with reperfusion failure and major adverse cardiac events, including heart failure and in-hospital mortality. Conclusions: ST resolution is not affected by the presence of diabetes. Although diabetics have higher prevalence of heart failure and in-hospital mortality after treatment of STEMI with streptokinase, their poor outcome is most likely due to higher burden of simultaneous coronary risk factors.
