Abstract: The most appropriate targets for systolic blood pressure to reduce cardiovascular morbidity and mortality among persons without diabetes remain uncertain.We randomly assigned 9361 persons with a systolic blood pressure of 130 mm Hg or higher and an increased cardiovascular risk, but without diabetes, to a systolic blood-pressure target of less than 120 mm Hg (intensive treatment) or a target of less than 140 mm Hg (standard treatment). The primary composite outcome was myocardial infarction, other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes. Leer más…

Blood pressure is a potent determinant of cardiovascular risk, but the most appropriate targets for blood-pressure lowering have long been debated. Observational studies with a low risk of confounding have shown a linear relationship between blood pressure and cardiovascular risk down to 115/75 mm Hg, but some observational studies with a greater potential for confounding, involving persons at increased risk, have suggested a J-shaped curve — that is, below a given blood pressure, risk would increase. When trials of blood-pressure–lowering drugs have shown benefits in patients without hypertension, these effects have often been ascribed to alternative mechanisms. The widespread uncertainty about blood-pressure targets was increased when the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial showed no significant overall difference in cardiovascular events between patients with type 2 diabetes assigned to a systolic blood-pressure target of less than 120 mm Hg and those assigned to a target of less than 140 mm Hg.
