Do calcium sensitizers affect right ventricular functions in patients with chronic heart failure?

Calcium sensitizers also improve cardiac function by increasing the contraction of the myocardium without significantly increasing intracellular calcium levels. Although right ventricular function is an important role for better cardiac global function, there is no study about effects of levosimendan on right ventricular function measured by tissue Doppler imaging. The aim of the present study was to evaluate changes of myocardial properties in patients with idiopathic dilated cardiomyopathy using tissue Doppler imaging after levosimendan infusion. This tissue Doppler study shows that levosimendan also affects myocardial especially systolic waves of right ventricle and those of left ventricle.
