Left ventricular systolic function is associated with sympathetic nervous activity and markers of inflammation in cirrhosis

An accurate evaluation of cardiac function in patients with cirrhosis remains a challenge. We used robust echocardiographic indices to characterize left ventricular (LV) systolic function and its relationship to activation of the sympathetic nervous system and inflammation in 59 patients with cirrhosis and 59 age-matched controls. Additionally, in 11 patients we withdrew beta-blockers and diuretics and used phenylephrine and albumin infusion to evaluate the response to acute afterload and preload changes (interventional substudy). Measures of systolic LV function such as the ejection intraventricular pressure difference (EIVPD) and the systolic strain rate were higher in patients with cirrhosis than in controls (median [1st-3rd quartile], 4.0 [3.1-5.1] versus 2.9 [2.4-3.6] mm Hg and -1.3 [-1.6 to -1.1] versus -1.2 [-1.6 to -1.1)] s-1 , respectively; P Conclusion LV systolic function is enhanced in cirrhosis due to augmented adrenergic tone and modulated by treatment with beta-blockers; acute afterload stress induces a deeper impairment of systolic function in patients with more advanced degrees of vasodilatation and inflammation; these changes in LV function related to cirrhosis can be assessed using robust echocardiographic methods.
