Does chronic aspirin treatment increase blood pressure in man?

Abstract

In postmyocardial infarction patients longterm aspirin treatment with 1.5 g/day led to a significant increase in systolic and diastolic blood pressure after 6 months. This could not be found in the placebo- and the phenprocoumon-treated patients. After one year the blood pressure behaviour was the same in all three treatment groups. As nonsteroidal antirheumatic drugs can produce hypertension in animals, probably due to inhibition of prostaglandin synthesis, blood pressure control in longterm aspirin treatment is advisable.
