TCT-312 Effects of Dobutamine and Glyceryl Trinitrate on coronary blood flow and the coronary wave intensity profile

Coronary blood flow (CBF) is uniquely dependent upon central aortic blood pressure (CBP) and myocardial microvascular resistance but the underlying mechanisms are ill-defined. Coronary wave intensity (CWI) permits aortic and myocardial forces acting on CBF to be resolved. CWI has identified two
