Objective: The appearance of collaterals during ST-elevation myocardial infarction (STEMI) and clinical factors potentially associated with their early appearance were studied. Background: The appearance of collaterals is associated with the duration of chronic coronary occlusion. Nevertheless, the question remains as to whether collaterals are already apparent shortly after an acute coronary occlusion. Results: The appearance of collaterals was studied during STEMI, in 187 patients who underwent angiography at various times after the onset of symptoms. For the onset-to-angiography groups of 0-6 h, >6-9 h, >9-24 h, >1-7 days, >7-14 days and >14 days, the prevalence of angiographic collaterals (Rentrop classification 2-3) were 19, 31, 41, 40, 50 and 68%, respectively (p < 0.001). Among the clinical factors, preinfarction angina was the only independent determinant (odds ratio 3.1; 95% CI: 1.2-8.5). Conclusion: As in chronic coronary occlusion, after acute occlusion the appearance of angiographic visible collaterals is also associated with the duration of occlusion. Preinfarction angina is an important clinical factor associated with the early appearance of collaterals.
