VISIT-TO-VISIT VARIABILITY OF SYSTOLIC BLOOD PRESSURE PREDICTS OUTCOMES MAINLY IN THE ACTIVE TREATMENT GROUP RATHER THAN THE PLACEBO GROUP IN THE SYSTOLIC HYPERTENSION IN THE ELDERLY PROGRAM: PATHOPHYSIOLOGIC IMPLICATIONS

Previous studies of blood pressure visit-to-visit variability (VVV) were of rather short duration and rarely included placebo. We investigated VVV of systolic blood pressure (SBP) in the active and placebo groups of Systolic Hypertension in the Elderly Program (SHEP). SHEP was a placebo-controlled
