myocardial blush

An angiographic term referring to the adequacy of perfusion and blood flow through an area served by a coronary artery; the longer the blush persists, the poorer the blood flow

myocardial blush

Cardiology The angiographic opacification of the myocardial microvasculature or vessels, the size of which can be planimetered so that the total area of the blush can be determined

We prospectively studied patients that underwent primary PCI within 12 hours of the onset of symptoms, had normal LVEF ([greater than or equal to]50%) at admission, had only single-vessel coronary disease, and underwent complete and successful revascularization (thrombolysis in myocardial infarction (TIMI) III flow and myocardial blush grade (MBG) III) during primary PCI.
De Luca et al13 found that pre-PCI good TIMI flow was strongly related to post-procedural TIMI 3 flow, myocardial blush grade 2-3 and lower enzymatic infarct size.
Other variables associated with mortality after PCI, such as ST-segment resolution, myocardial blush grade, thrombolysis in myocardial infarction flow grade, and hemodynamic data were not studied.
Time-to-treatment significantly affects the extent of ST-segment resolution and myocardial blush in patients with acute myocardial infarction treated by primary angioplasty.
No significant difference was found in ST resolution within 60 minutes (72.6 vs 81.8 %; P less than 0.285) and myocardial blush grade II and III (41.9 vs 27.3 %; P less than 0.128).
Relation of coronary flow pattern to myocardial blush grade in patients with first acute myocardial infarction.
Type II CAP is defined by the development of a pericardial or myocardial blush, without contrast jet extravasation.
The primary end points were postprocedural assessment of TIMI flow, corrected thrombolysis in myocardial infarction (TIMI) frame count, and myocardial blush grade [7]; these parameters were measured by the PCI operator who was blinded.
After aspiration thrombectomy, TIMI III flow and a myocardial blush grade (MBG) score of 2 were achieved (Fig.
To measure impaired microvascular perfusion after primary PCI, these authors used ST-segment resolution of <70%, myocardial blush grade 0 or 1, or a corrected Thrombolysis in Myocardial Infarction (TIMI) frame count >28.
The primary endpoints of the DEAR-MI study were a comparison of myocardial reperfusion according to ST-segment resolution and myocardial blush grade.
