“…In humans, pulmonary input impedance can be measured using a catheter with tip-mounted flow probe and pressure transducer [ 16 ]. Zc was reported to be 20–37 dyn·s/cm 5 in normal adults [ 17 – 22 ], and 46–124 dyn·s/cm 5 in patients with pulmonary hypertension [ 17 , 19 , 21 , 23 , 24 ] (Table 1 ). Several studies also report measurement of pulmonary input impedance in clinical settings using pressure recorded by fluid-filled catheter systems and flow velocity simultaneously recorded by Doppler echocardiography [ 24 , 25 ].…”

Diagnostic and therapeutic methods for cardiovascular diseases continue to be developed in the 21st century. Clinicians should consider the physiological characteristics of the cardiovascular system to ensure successful diagnosis and treatment. In this review, we focus on the roles of cardiovascular physiology in recent diagnostic and therapeutic technologies for cardiovascular diseases. In the first section, we discuss how to evaluate and utilize left ventricular arterial coupling in the clinical settings. In the second section, we review unique characteristics of pulmonary circulation in the diagnosis and treatment of pulmonary hypertension. In the third section, we discuss physiological and anatomical factors associated with graft patency after coronary artery bypass grafting. In the last section, we discuss the usefulness of mechanical ventricular unloading after acute myocardial infarction. Clinical development of diagnostic methods and therapies for cardiovascular diseases should be based on physiological insights of the cardiovascular system.

“…Aside from study of pulmonary Zc patterns in healthy individuals and Pre‐cPH, limited work has been done to evaluate pulmonary Zc in patients with PH secondary to mitral stenosis or left ventricular failure. Patterns of pulmonary Zc in patients with mitral stenosis and/or left ventricular failure have previously demonstrated an increase in the resistive component of modulus, an increase in frequency of the first minimum of the modulus and of phase cross over, as well as an increase in pulmonary Zc (Chen et al, 1990 ; Kussmaul et al, 1992 , 1988 ; Milnor et al, 1969 ). These findings were also observed of our cohort with Ipc‐PH.…”
