摘要: This study compared the TIMI frame count (TFC), which has been proposed as a method for quantifying coronary blood flow, with flow and microvascular function measured intracoronary Doppler ultrasound. Coronary volume was calculated from velocity (by Doppler) lumen area ultrasound) in LAD 46 post-heart transplant patients at baseline after adenosine. TFC correlated significantly average peak (r = -0.42; P 0.004) 0.39; 0.008), but not -0.01; 0.96) or reserve response to adenosine 0.09; 0.58). In conclusion, is simple of assessing volumetric flow. While does predict reserve, measure it provide an assessment basal tone, information that complementary afforded by measurements.
