I found a Finnish paper that looked at the ratio of VO2max to systolic BP in men, the cohort was split into 4 based on this ratio and those with the highest ratio had the least stroke occurrences over the study period.
So good fitness (high VO2max) and low BP minimise stroke risk. If HIIT improves fitness and reduces blood pressure it will help.
