Perfusion and Function in the Normal and Abnormal Heart

Absolute Myocardial Blood Flow

“…They do, however, vary directly with changes in arterial pressure and inversely with changes in heart rate (1). They do, however, vary directly with changes in arterial pressure and inversely with changes in heart rate (1).…”

Ranolazine and the Myocardial Demand–Supply Balance

“…Extravascular compressive forces have complex effects on impedance to flow, involving important capacitive and inertial as well as resistive factors (6). Although, ranolazine-induced reductions in diastolic dysfunction are receiving increasing attention, its effects on microvascular resistance vessels remain undefined.…”
