The ultrastructure and adenosine diphosphate induced aggregatory response of platelets of 39 patients with essential hypertension have been studied. Both, transmission and scanning electron microscopy showed the co-existence of various morphological forms of platelets suggestive of activation. The hypertensive platelets also exhibited increased sensitivity to ADP induced aggregation confirming the activated state of platelets; the degree of activation correlated well with the levels of diastolic blood pressure.
