Can bouts of high blood pressure be dangerous for your heart?

As with yesterday, whenever i get worried or anxious or stressed, my blood pressure gets extremely high and i start having chest pains. like yesterday, it went up to 170 over 115 then after i was taken to the e.r. and calmed down my blood pressure was 130 or 75. Can having these bouts of high blood pressure be dangerous? Other than that, tests have ruled out heart problems.
Im diagnosed with bipolar 1 disorder, psychosis, and anxiety disorders.
