Complete occlusion of coronary artery is denoted by which score in TIMI by angiography?
Correct Answer: 0
Description: Ans. A. 0Coronary AngiographyWhen assessed angiographically, flow in the culprit coronary artery is described by a simple qualitative scale called the thrombolysis in myocardial infarction (TIMI) grading system:a. Grade 0 indicates complete occlusion of the infarct-related arteryb. Grade 1 indicates some penetration of the contrast material beyond the point of obstruction but without perfusion of the distal coronary bedc. Grade 2 indicates perfusion of the entire infarct vessel into the distal bed but with flow that is delayed compared with that of a normal arteryd. Grade 3 indicates full perfusion of the infarct vessel with normal flow.
