ABSTRACT
OBJECTIVES:
We sought to develop a new quantitative method to evaluate the degree of myocardial perfusion.BACKGROUND:
Currently available methods for assessing myocardial perfusion, both TIMI myocardial perfusion grading (TMPG) and myocardial blush grading (MBG), are subjective.METHODS:
TIMI Myocardial Perfusion Frame Count (TMPFC), an objective method that measures the filling and clearance of contrast in the myocardium using cine-angiographic frame-counting, was developed to quantify myocardial perfusion. Myocardial perfusion of 45 normal coronary arteries in 15 patients, and 137 culprit arteries in 137 patients immediately after primary angioplasty, was successfully assessed with TMPFC.RESULTS:
The mean TMPFC in the normal arteries was 83.47 +/- 17.96 frames (95% CI 78.07 framesCONCLUSIONS:
TMPFC is a quantitative index for the assessment of myocardial perfusion; it allows quantification of TMPG and may serve as a discerning tool to predict prognosis in patients undergoing primary angioplasty.
