Platelet aggregation and dense granule secretion in a colony of dogs with spontaneous hypertension.

Abstract:

AIM:Since canine hereditary essential hypertension has been previously reported in a colony of Siberian husky dogs, we tested the suitability of this model for use in studies on the platelet defect identified in humans with essential hypertension. METHODS:Platelet aggregation and dense granule ATP secretion were measured in dogs with essential hypertension and normotensive control dogs. RESULTS:The platelets from the hypertensive group showed significantly increased aggregation and secretion in response to stimulation with ADP. There was no significant increase in aggregation or secretion when platelets from hypertensive dogs were stimulated by platelet-activating factor, thrombin, calcium ionophore A23187 or phorbol myristate acetate. CONCLUSION:The increased aggregation and secretion responses in platelets from the hypertensive dogs suggest that a defect similar to that reported in humans with essential hypertension exists and that further investigation is warranted.

Arterial stiffness, however, is pressure dependent. At the carotid artery level, the degree of this dependency can be quantified as the difference (ΔPWV) between systolic and diastoli...
