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...

AT1 receptors: coronary flow and flow reserve.

Angiotensin II, through its effects at the angiotensin-type 1 receptor, elevates arterial pressure and exacerbates hypertensive heart disease. Alterations in coronary hemodynamics, including reductions in coronary blood flow and flow reserve promotes coronary insufficiency and contributes to the increased cardiovascular risk associated with these conditions. In spontaneously hypertensive rats, ...

Pressure-derived measurement of coronary flow reserve.

OBJECTIVES We aimed to validate the technique of measuring the coronary flow reserve (CFR) with coronary pressure measurements against an established thermodilution technique. BACKGROUND The CFR has traditionally required measurement of coronary blood flow velocity with the Doppler wire and, more recently, using a thermodilution technique with the coronary pressure wire. However, recent work ...
