Question: Is evidence from comparative investigations that impaired platelet activation specific for stroke-prone spontaneously hypertensive rats?
Answer: Because indistinguishable results were observed in both hypertensive strains, we conclude that impaired platelet aggregation is not specific for SHRSP. Hence, it may not primarily be responsible for the increased occurrence of stroke in these animals.
no
