Lowering Blood Glucose in Prediabetes May Protect Your Heart

Recent research suggests that lowering blood glucose levels in people with prediabetes could dramatically reduce the risk of heart attacks and heart failure. These findings are changing the way experts think about preventing cardiovascular disease in this population.

Prediabetes and Heart Health: What You Need to Know

Prediabetes affects over 1 billion people worldwide, with more than one in three adults in the U.S. alone. It occurs when blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes (T2D). While prediabetes often shows no symptoms, early damage to the heart, blood vessels, and kidneys may already be occurring.

Some subtle warning signs may include:

• Darkened skin patches on the neck, armpits, or groin
• Increased thirst or frequent urination
• Fatigue, blurred vision, or numbness
• Slow-healing sores or frequent infections
• Unintended weight loss

Without intervention, prediabetes often progresses to T2D, which increases cardiovascular risk.

Lifestyle Changes Alone May Not Be Enough

While diet improvements, regular exercise, and weight loss are important for overall health, new evidence shows that these lifestyle changes alone may not significantly reduce heart attack or cardiovascular death risk in people with prediabetes.

“This study challenges one of the biggest assumptions in modern preventative medicine,” said Andreas Birkenfeld, lead study author and reader in diabetes at King’s College London. “We show that remission of prediabetes is associated with a clear reduction in fatal cardiac events, heart failure, and all-cause mortality.”

Prediabetes Remission Reduces Long-Term Cardiovascular Risk

Researchers analyzed long-term data from two major diabetes prevention trials—the U.S. Diabetes Prevention Program Outcomes Study (DPPOS) and the Chinese DaQing Diabetes Prevention Outcomes Study (DaQingDPOS). Participants with prediabetes were followed for decades to assess the impact of interventions like exercise and healthy eating.

Key findings include:

• Achieving remission from prediabetes lowered the risk of cardiovascular death or hospitalization from heart failure by approximately 58%.
• Risk of heart attack, stroke, and other major cardiovascular events decreased by about 42%.
• Benefits persisted for decades, showing lasting cardiovascular protection.

These results suggest that targeting blood glucose levels directly, alongside traditional measures like controlling blood pressure, cholesterol, and avoiding smoking, may become a powerful strategy for preventing heart disease.

Lowering blood sugar in prediabetes isn’t just about preventing diabetes—it could also be a key tool for protecting your heart. Monitoring blood glucose and seeking early interventions could be life-changing for millions at risk of heart disease.
