Importance of the TIMI frame count: implications for future trials
Although the TIMI (Thrombolysis In Myocardial Infarction) flow grade classification scheme is widely used to assess angiographic outcomes, it is limited by poor reproducibility and its categoric nature. The corrected TIMI frame count (CTFC) is a simple, more objective continuous variable index of coronary blood flow that can be broadly and inexpensively applied. This measure of the time for dye...
متن کاملIs the corrected TIMI frame count an independent predictor of adverse outcome?
Independent Predictor of Adverse Outcome? To the Editor: The corrected TIMI frame count (cTFC) has evolved into a standard measurement in many angiographic core laboratories. Although the reproducibility of the cTFC has been demonstrated,1,2 its superiority to TIMI flow grading has remained in question. Work done in our core laboratory has not found the cTFC to have predictive value independent...
متن کاملCoronary microvascular dysfunction in patients with microvascular angina: analysis by TIMI frame count.
We have previously reported that angina pectoris persists in patients with coronary microvascular spasm (MVS) even on calcium channel blockers. Because measurement of myocardial lactate production in the coronary sinus is necessary to diagnose MVS, a more feasible diagnostic method needs to be developed. In this study, we examined the diagnostic significance of Thrombolysis in Myocardial Infarc...
متن کاملEffect of potential confounding factors on the thrombolysis in myocardial infarction (TIMI) trial frame count and its reproducibility.
BACKGROUND The potential factors that introduce variability into TIMI frame count (TFC) have not been systematically investigated. The goal of this study was to determine if nitrate use, dye injection rate, catheter size, the phase of the cardiac cycle in which dye is injected, or heart rate affect the TFC and to investigate the reproducibility of the TFC. METHODS AND RESULTS The dye injectio...
متن کاملFrame count reserve.
BACKGROUND The Doppler wire-derived (relative) coronary flow velocity reserve (CVR) that is used to evaluate functional significance of a coronary stenosis is a method performed only by interventional cardiologists. An angiographic method would be useful in the diagnostic catheterization laboratory. For this purpose, we investigated the relation between TIMI frame count reserve (FCR) and CVR. ...
