Dobutamine stress echocardiography for evaluating cirrhotic cardiomyopathy in liver cirrhosis
BACKGROUND/AIMS The blunted ventricular systolic and diastolic contractile responses to physical and pharmacological stress in cirrhosis are termed cirrhotic cardiomyopathy (CCM). CCM has been known to involve multiple defects in the β-adrenergic signaling pathway. The aim of this study was to determine whether cirrhotic patients have blunted cardiac responses to catecholamine stimulation throu...
متن کاملCirrhotic cardiomyopathy.
Cirrhotic cardiomyopathy is a clinical syndrome in patients with liver cirrhosis characterized by an abnormal and blunted response to physiologic, pathologic, or pharmacologic stress but normal to increased cardiac output and contractility at rest. As many as 50% of cirrhotic patients undergoing liver transplantation show signs of cardiac dysfunction, and 7% to 21% of deaths after orthotopic li...
متن کاملCirrhotic cardiomyopathy
Cardiomyopathy is a chronic disease of the myocardium characterized by an abnormal dilatation and thinning of the left ventricular (LV), associated with the contractile dysfunction of the muscle and loss of pump capacity, resulting in the occurrence of arrhythmias and myocardial infarction. It has many causes and can occur in the liver pathology inclusively.
متن کاملCirrhotic cardiomyopathy.
During the course of cirrhosis, there is a progressive deterioration of cardiac function manifested by the disappearance of the hyperdynamic circulation due to a failure in heart function with decreased cardiac output. This is due to a deterioration in inotropic and chronotropic function which takes place in parallel with a diastolic dysfunction and cardiac hypertrophy in the absence of other k...
متن کاملCirrhotic cardiomyopathy
Most patients with liver cirrhosis have hyperdynamic circulatory alterations with increased cardiac output, and decreased systemic vascular resistance and arterial pressure. But, in spite of the increased resting cardiac output, ventricular contractile response to stressful stimuli is attenuated in cirrhotic patients which is termed as cirrhotic cardiomyopathy. The prevalence of cirrhotic cardi...
