Striving to keep systolic blood pressure (the first number in a reading) to 120 millimetres of mercury (mm Hg) or lower offers greater heart health protection for people with type 2 diabetes, high blood pressure, and other risk factors for cardiovascular disease compared to a less aggressive goal, according to a study published online Nov. 16, 2024, by The New England Journal of Medicine.
Half of the nearly 13,000 study subjects were assigned to aggressively reduce their blood pressure to 120 mm Hg or lower, often by taking multiple medications, and the other half were given an easier goal of less than 140 mm Hg. After an average of four years, the incidences of major cardiovascular events (including stroke or heart attack) among people assigned to the goal of no more than 120 mm Hg were significantly lower than among those assigned to less than 140 mm Hg (whose average reading was 135 mm Hg).
Most current guidelines recommend a systolic blood pressure of less than 130 mm Hg for people with diabetes, but these results are consistent with other studies that suggest reducing blood pressure to around 120 mm Hg or lower may offer the most benefit.
