Intensive glycemic control reduces cardiovascular mortality only in patients with early-stage diabetes (duration <10-15 years), whereas it may increase mortality in patients with long-standing diabetes.

If you have had Type 2 Diabetes for many years (over 10), aiming for very low blood sugar levels might actually increase your risk of death due to side effects like severe hypoglycemia. Focus on stable control rather than aggressive lowering. If you have recently been diagnosed, aggressive control can provide long-term 'legacy' protection for your heart.

GoodQualifiesHIGH confidence
the impact of intensive glycemic control on mortality in these two studies was diametrically opposite, i.e., positive in the UKPDS follow-up... and negative in the ACCORD trial... The hypothesis that the mortality benefit of intensive glucose lowering is restricted to subjects with early diabetes is further substantiated by a stratified analysis from Veteran’s Affairs Diabetes Trial (VADT) follow-up study

Why this rating

Supported by multiple large CVOTs (UKPDS, ACCORD, VADT, DCCT/EDIC) showing divergent mortality outcomes based on duration.
