Elevation of taurine in human congestive heart failure

The concentration of taurine in the left ventricle of the heart was doubled in patients who had died of chronic congestive heart failure compared to patients who had died of other causes and had no cardiac pathology. In the absence of congestive heart failure, a similar elevation in taurine level was seen in patients with high blood pressure compared to patients with lower blood pressures. The levels of taurine in heart failure were not affected by digitalis treatment. The concentration of taurine in the aorta was almost the same in patients who had died of congestive heart failure and patients who had died of other causes, suggesting that the increase in concentration of taurine might be specific to the heart.
