Non-invasive imaging of global and regional cardiac function in pulmonary hypertension
Pulmonary hypertension (PH) is a progressive illness characterized by elevated pulmonary artery pressure; however, the main cause of mortality in PH patients is right ventricular (RV) failure. Historically, improving the hemodynamics of pulmonary circulation was the focus of treatment; however, it is now evident that cardiac response to a given level of pulmonary hemodynamic overload is variabl...
متن کاملNon-Invasive Determination of Cardiac Output in Pre-Capillary Pulmonary Hypertension
BACKGROUND Cardiac output (CO) is a major diagnostic and prognostic factor in pre-capillary pulmonary hypertension (PH). Reference methods for CO determination, like thermodilution (TD), require invasive procedures and allow only steady-state measurements. The Modelflow (MF) method is an appealing technique for this purpose as it allows non-invasive and beat-by-beat determination of CO. METHO...
متن کامل[Non-invasive assessment of cardiac function].
Noninvasive assessment of cardiac function by Doppler echocardiography is reviewed. The heart propels the blood through the repeated sequence of systole and diastole. The systolic function is essential to maintain the biological function of the whole body. However, before the heart ejects the blood during systole, the heart must be filled up with blood during the preceding diastole. Thus, the d...
