Background Cardiovascular abnormalities are associated with liver cirrhosis observed especially under conditions of stress, so it is important to evaluate the cardiovascular function in every patient with cirrhosis. The Child–Pugh scoring system is the most commonly used clinical method for classifying liver cirrhosis. Tissue Doppler imaging and Two-dimensional speckle-tracking echocardiography (2D-STE) are newer imaging modalities able to accurately quantify left ventricular (LV) systolic function. Aim To assess LV functions in patients with chronic liver cirrhosis caused by hepatitis C virus by different echo modalities and correlate the results with the severity of cirrhosis based on Child–Pugh score. Material and methods A prospective study was done in the Echocardiography Unit, Cardiology Department, Al-Zahraa University Hospital, during a period of one year, including 75 participants, with 45 cirrhotic patients and 30 healthy individuals. For all patients, 2D-STE of the LV was measured. Then the patients with liver cirrhosis were divided into three subgroups according to Child–Pugh score, and LV functions were evaluated with conventional echo, tissue Doppler imaging (TDI), and STE. Results By conventional echo, the LV systolic function increased in the diseased group (P=0.004) but decreased when using TDI and STE. Then the patient group was divided into three subgroups based on the Child–Pugh score. By conventional echo parameters, there were normal LV dimensions in the three groups but increased in class C with lowered systolic function by using 2D-STE. Conventionally, LV diastolic dysfunction was diagnosed in 30% but in 75% when using TDI. There is a correlation between severity of liver cirrhosis and LV systolic dysfunction when measured only by 2D-speckle tracking. Conclusion The 2D-STE is considered a useful tool for early detection of LV systolic dysfunction especially in asymptomatic patients with viral liver cirrhosis. The LV diastolic dysfunction occurs earlier in cirrhotic patients. There is correlation between the extent of severity of liver cirrhosis and LV systolic dysfunction.
