Platelet taurine in patients with arterial hypertension, myocardial failure or infarction

The content of taurine in the hypertrophied left ventricle is increased in congestive heart failure an in spontaneously hypertensive (SH) rats. In SH rats the taurine content of and taurine uptake by the platelets are also increased. The present results indicate that, as in the heart, the taurine content may also increase in the platelets of those patients with congestive heart failure. The taurine content and uptake are not increased in the platelets of hypertensive patients as they are in the platelets of SH rats. It is likely that in acute myocardial infarction, a considerable amount of taurine is released from the heart into the plasma. However, there is no simultaneous increase in the platelet taurine content. From this work on can only conclude that platelets may reflect taurine changes in the heart in some pathological states, e.g. congestive heart failure.
