The cardio-ankle vascular index (CAVI) has been recently reported as a new index of arterial stiffness, which is less influenced by blood pressure than pulse wave velocity. We investigated the relationship between CAVI and myocardial ischemia as assessed by supine exercise echocardiography (SEE). In order to study the ejection characteristics of the left ventricle (LV) a computer model describing the LV systole in different preloading conditions was developed, allowing the evaluation of the wall stress at end-systole and the end-systolic pressure. Using echocardiographic recordings, we investigated the relationship between the vascular and ventricular stiffness indices.

The investigations for establishing the etiology of syncope were extended over 4 years and multiple possible mecahisms for the syncope were identified. Even if the guidelines mention a good diagnostic yield for history and initial evaluation, for some selected cases the initial diagnostic supposition should be revised.

Previous studies show common pathogenetic mechanisms involved in the development of hepatopulmonary syndrome and cirrhotic cardiomyopathy. We aimed to assess the link between these entities and their effect on disease-related patient morbidity and mortality. Seventy-four consecutive cirrhotic patients without prior history of cardiovascular and pulmonary disease were included in a prospective observational study. Routine blood work, arterial blood gas analysis, pulse oximetry measurements, N-terminal pro-brain natriuretic peptide levels and contrast enhanced echocardiography examination with tissue Doppler imaging were performed in all patients. Patients were followed up for a median of 6 months and disease-related adverse events and death were the main outcomes tested. Statistical analysis was conducted according to the presence of hepatopulmonary syndrome or cirrhotic cardiomyopathy. Hepatopulmonary syndrome was diagnosed in 17 patients (23%) and cirrhotic cardiomyopathy in 30 patients (40.5%). There was no association between the presence of cirrhotic cardiomyopathy and the existence of mild or moderate hepatopulmonary syndrome. No echocardiographic parameters were useful in predicting the presence of hepatopulmonary syndrome. N-terminal pro-brain natriuretic peptide levels and length of QT interval did not aid in diagnosis of cirrhotic cardiomyopathy. Neither entity had significant influence on disease-related outcomes in the follow-up period. Hepatopulmonary syndrome and cirrhotic cardiomyopathy are independent complications arising in cirrhosis and have a limited influence on morbidity and mortality on a pre-liver transplantation population.
