RT Journal Article SR Electronic T1 Tools for noninvasive assessment of coronary arterial reperfusion JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 403 OP 408 VO 59 IS 4 A1 Richard C. Becker YR 1992 UL http://www.ccjm.org/content/59/4/403.abstract AB For patients with acute myocardial infarction, the presence of a patent infarct-related coronary artery may be the most sensitive single predictor of clinical outcome and patient survival. Coronary angiography is the most direct means of assessing reperfusion status; however, availability, cost, and risk are potential concerns. Noninvasive markers are emerging which can reliably and rapidly determine vessel patency, circumventing the need for routine angiography.
