“…In a prior study looking at the timing of coronary collateral appearance during STEMI, the investigators identified an increase in prevalence of collaterals with increasing duration of symptoms prior to angiography. 23 In that study, the median symptom to angiography time was 9.9 hours.…”

Background Coronary collaterals are often seen supplying retrograde flow to an acutely occluded arterial territory. Whether this early collateralization offers prognostic benefit is not well established. Methods We analyzed data from all patients presenting to our regional cardiac unit with acute ST‐elevation myocardial infarction requiring immediate angiography (years 1999–2017). Data on all patients is entered prospectively into a bespoke tailored database prior to knowledge of patient outcome. Only patients with TIMI 0 or 1 flow in the infarct‐related vessel were included in the analysis. In‐hospital and long‐term outcome were assessed according to the presence or absence of angiographically visible collateral flow prior to treatment of the occluded vessel. Results Two thousand five hundred and forty‐two patients were included in the analysis. 76% of these (n = 1944) had TIMI 0/1 flow at angiography. Angiographically‐visible collateralization was seen in 17% (n = 322) and was more commonly observed in the right coronary artery (64%) than in the left anterior descending (25%) or Cx (6%). Cardiogenic shock (10.8%) and use of an intra‐aortic balloon pump (5.4%) were more frequent in patients without coronary collateralisation (p = .04 and p = .02, respectively). The presence of collaterals improved long term survival (95% CI 11.4–18.7 months; p < .01). Conclusion One‐sixth of patients with STEMI have angiographically visible collaterals to the infarcted territory. Patients without collaterals are more likely to present in cardiogenic shock. The presence of angiographically visible collaterals at the time of STEMI is associated with an improved long‐term survival.

“…Generally, it takes 3 to 5 days after coronary occlusion before there is measurable collateral. Interestingly, however, Ng S et al's studies have found that a substantial percentage (10% to 20%) of individuals develop collaterals in acute myocardial infarction and this is confirmed also by Elsman P et al's (Ng S, et al 2012) studies (Elsman P et al 2012) (Elsman P, et al 2004).…”

“…When area at risk area reduces, the infarct size will be smaller, and hemodynamic and fatal arrhythmic complications that occur after myocardial infarction could also be avoided. Moreover, successful acute revascularization could still be achieved after unavoidable logistical delays if more area could be saved and maintained through collateral flow presence (Ng S, et al 2012).…”

Coronary collateral artery (CCA) is an alternative source of blood supply to an ischemic myocardial region. It is generally believed that there is a beneficial effect of collaterals in patients with coronary artery disease (CAD).Recently, reliable methods have become available for the assessment of the adequacy of collateral flow. However, the debate regarding the importance of CCA in the different clinical settings continues. In this review article, we discuss about the functional relevance of CCA to provide an overview of its impact on the prognosis of patients with CAD.
