Genetic subgrouping of stroke-prone SHR and stroke-resistant SHR

From these results, we can conclude that the developmental pattern of hypertension in the young age is genetically determined and closely related to the incidence of hemorrhage or infarction. These newly selected substrains of SHRSP with higher incidences of cerebral infarction (SP-2) or hemorrhage (SP-1) are regarded as the better models for studying the pathogenesis, treatment, and prevention of infarction or hemorrhage, respectively.
