Despite the increased cardiac output, ventricular inotropic and chronotropic responses to stimuli are blunted, a condition known as "cirrhotic cardiomyopathy". These include systolic and diastolic dysfunction, electrophysiological changes, and structural changes. There are no clear consensus definition for this condition. Cardiac function was evaluated by classic echocardiography, 2D and color/spectral Doppler: cardiac dimensions, left ventricular ejection fraction (LVEF), systolic and diastolic timings. All of these changes are dependent on load conditions, and cirrhosis has major variability of preload conditions. However, these conventional measurements allow only the late diagnosis of cardiac dysfunction, which might be already irreversible.
