The impact of chronically diseased coronary arteries and stenting on the corrected TIMI frame count in elective coronary angiography and percutaneous coronary intervention procedures

The impact of chronic coronary obstructions on resting blood flow in stable cardiac patients and the response to percutaneous coronary intervention (PCI) using the TIMI frame count method has not been well documented. We studied the impact of coronary artery stenosis severity on the corrected TIMI f...

Zusammenfassung:	The impact of chronic coronary obstructions on resting blood flow in stable cardiac patients and the response to percutaneous coronary intervention (PCI) using the TIMI frame count method has not been well documented. We studied the impact of coronary artery stenosis severity on the corrected TIMI frame count (cTFC) in chronically stenosed coronary arteries. We prospectively and quantitatively determined the impact of stenting on the cTFC during elective PCI. Methods: In substudy 1, analysis was performed to obtain the mean cTFC for arteries with
