What is the relationship between low diastolic BP and primary outcome?
The relationship between low diastolic BP and primary outcome is J-shaped, such that the primary outcome occurred least frequently at a systolic BP of 135-145mmHg and a diastolic BP of 60-90mmHg. Further analysis of the association including only the 2699 patients with peripheral artery disease showed a J-shaped relationship, with a HR nadir at 75mmHg up to 80 years, then 70mmHg for subjects 480 years.
