Coronary Flow Reserve and Pharmacologic Stress Perfusion Imaging

Coronary flow reserve and pharmacologic stress perfusion imaging: beginnings and evolution.

Relative coronary flow velocity reserve improves correlation with stress myocardial perfusion imaging in assessment of coronary artery stenoses.

STUDY OBJECTIVE To evaluate the angiographic and coronary flow velocity parameters that best correlate with the results of stress myocardial perfusion imaging. DESIGN Criterion standard. SETTING Tertiary care center. PATIENTS Forty-eight patients undergoing diagnostic coronary angiography for angina or silent ischemia. INTERVENTIONS We performed angiographic and coronary flow velocity m...

CORONARY FLOW RESERVE Digital subtraction angiographic imaging of coronary flow reserve

Recent studies have demonstrated that subjective assessment of the severity of coronary artery stenoses results in poor interobserver concordance and poor correlation with physiologic significance as determined by Doppler measurements of coronary flow reserve. Use of the coronary flow reserve as an integrated measure of the effect of stenosis geometry has been emphasized within the context of q...

Diagnostic accuracy of stress myocardial perfusion imaging compared to invasive coronary angiography with fractional flow reserve meta-analysis.

BACKGROUND Hemodynamically significant coronary artery disease is an important indication for revascularization. Stress myocardial perfusion imaging is a noninvasive alternative to invasive fractional flow reserve for evaluating hemodynamically significant coronary artery disease. The aim was to determine the diagnostic accuracy of myocardial perfusion imaging by single-photon emission computed...
