The Claim

The reduction in cardiovascular events achieved by intensive blood pressure control in adults with type 2 diabetes is contingent on the level of glycemic control, with significant benefit occurring only under standard glycemic management and not under intensive glycemic management.

Cause and effect
1 study reviewed
In plain English

In adults with type 2 diabetes, lowering blood pressure aggressively reduces cardiovascular events only when blood sugar is managed at a standard level, not when it is managed aggressively.

See the scientific wording

The benefit of intensive blood pressure control in reducing cardiovascular events among adults with type 2 diabetes is dependent on the intensity of glycemic control, with significant benefit observed only under standard, not intensive, glycemic management.

Why this might work

When blood sugar stays too high for too long, it damages the lining of blood vessels, making them stiff and less able to respond when blood pressure is lowered. This damage prevents the vessels from relaxing properly, so lowering blood pressure further doesn't improve blood flow or reduce strain on the heart. But when blood sugar is kept at normal levels, the blood vessels stay flexible and can respond to lower pressure by relaxing, which protects the heart and blood vessels.

    When people with type 2 diabetes have their blood sugar controlled normally (not super tight), lowering their blood pressure a lot helps prevent heart problems. But if their blood sugar is already super tightly controlled, lowering blood pressure even more doesn’t help anymore.
