Cardiovascular disease, or heart disease, can be a complication of type 1 diabetes (T1D) due to the uncontrolled rise and fall of blood sugar levels damaging nerves and blood vessels. A new study has now shown that adults could reduce their risk of fatal heart disease by using insulin pump therapy instead of multiple daily injections (MDI).

In this study out of Denmark, researchers monitored the medical data of over 18,000 adults with T1D. This data was from the Swedish National Diabetes Register from 2005-2012.

The researchers found that people who were on insulin pump therapy had a 45% lower risk of dying from heart attack or stroke compared with those on MDI, even though HbA1C levels were similar between the two groups.

Previous studies have shown that both hypoglycaemia and hyperglycaemia increase the risk of cardiovascular complications in T1D. Insulin pump use tends to result in more stable blood glucose levels, even when the average levels (HbA1Cs) remain the same when compared with MDI treatment.

This study showed that insulin pump therapy for adults with T1D considerably reduced the risk of dying from cardiovascular disease, which is one of the leading causes of death in people with T1D. Access to affordable diabetes technology is essential for enhanced quality of life and improved health for people with T1D.
