Insights
Cirrhotic cardiomyopathy (CCM) is prevalent in 61% of patients using standard echocardiograms, but only 45% when using tissue Doppler imaging (TDI). TDI offers a more accurate diagnosis of cardiac dysfunction in cirrhosis.
Area of Science:
- Cardiology
- Gastroenterology
- Medical Diagnostics
Background:
- Cirrhotic cardiomyopathy (CCM) is a complex cardiac dysfunction affecting patients with liver cirrhosis.
- Current diagnostic criteria rely on echocardiography, but the sensitivity and specificity vary.
- Tissue Doppler imaging (TDI) shows promise for more accurate cardiac assessment in cirrhosis.
Purpose of the Study:
- To estimate the pooled prevalence of CCM using conventional 2D echocardiography and TDI.
- To compare the diagnostic accuracy of 2D echocardiography versus TDI for CCM.
- To establish population-specific echocardiographic values for cirrhotic patients.
Main Methods:
- Meta-analysis of 12 selected cohort studies.
- Inclusion of studies using either conventional 2D echocardiography or TDI for CCM diagnosis.
- Analysis of echocardiographic data from 615 cirrhotic patients.
Main Results:
- The pooled prevalence of CCM was 61% using the 2005 criteria with conventional echocardiography.
- Using TDI, the pooled prevalence of CCM decreased to 45%.
- Mean echocardiographic values in cirrhotic patients included LVEF 63.52%, deceleration time 229.04 ms, IVRT 87.71 ms, and E/A ratio 1.04.
Conclusions:
- Conventional 2D echocardiography may lead to overdiagnosis of CCM compared to TDI.
- TDI demonstrates higher sensitivity and specificity for detecting cardiac dysfunction in cirrhotic patients.
- Accurate diagnosis of CCM is crucial for patient management and prognosis.
Abstract:
The proposed diagnostic criteria for cirrhotic cardiomyopathy (CCM), defines it as documented echocardiographic findings of systolic or diastolic dysfunction (using conventional 2D echocardiogram), with or without electrophysiological abnormalities or elevated biomarkers in cirrhotic patients. In comparison to 2D echocardiogram, tissue Doppler imaging (TDI) has better sensitivity and specificity, when evaluating for cardiac dysfunction. This meta-analysis of 12 selected cohort studies attempted to estimate the pooled prevalence of CCM using either conventional echocardiography or TDI. Using the 2005 criteria, the pooled prevalence of CCM is 61% (P = 0.106). When TDI is used, the prevalence of CCM is at 45% (P = 0.088). Analyzing data of 615 cirrhotic patients, this study estimates the mean population-specific echocardiographic values of cirrhotic patients, including left ventricle ejection fraction (63.52%), deceleration time (229.04 ms), isovolumetric relaxation time (87.71 ms) and E/A ratio (1.04). In comparison to TDI, using standard 2D echocardiography leads to overdiagnosis of CCM.
