Treatments
Studied treatment |
tighter control of systolic BP with a goal of <130 mm Hg
One SBP measure higher than 130 mm Hg at any visit led to intensification of treatment. The choice of drugs in individual patients was left to the discretion of the investigators
|
Control treatment |
usual control, with a goal of <140 mm Hg
achievement of an SBP <130 mm Hg entailed down-titration of treatment. The choice of drugs in individual patients was left to the discretion of the investigators
|
Treatments description |
Achieved systolic blood |
131.9 / 135.6 mmHg |
Achieved diastolic blood pressure |
77.4 / 78.7 mmHg |
|
