Table 2 Data of 75 patients undergoing elective coronary angiography: The degree of stenosis was calculated by quantitative angiography in two orthogonal planes. Mean values ± standard deviations (SD), APV: highest value of the average peak velocity (under baseline conditions and maximal hyperemia), the coronary flow velocity reserve was measured before angioplasty (CFVR before PCI) in 75 patients, and after angioplasty (CFVR post PCI) in 42 patients.
