Low BP may raise CHD risk in diabetes

The study in 30,000 patients with diabetes over six years showed that a baseline systolic/diastolic blood pressure (BP) of less than 110/65mmHg at baseline was associated with a 73% increased risk of CHD in African-American patients and a 60% increased risk in white patients.

The association between BP at baseline and CHD was U-shaped with the lowest point of CHD risk at 130–140mmHg systolic and 80–90mmHg diastolic BP.

The U-shaped association of BP and CHD applied to patients aged 30–49 and 50–59 but changed to an inverse
