High blood sugar levels in heart failure patients linked with early death

Heart failure patients who are admitted to hospital are at greater risk of dying if they have high blood sugar, according to new research.

Researchers followed over 16,500 heart failure patients who were admitted to hospital in Toronto between 2004 and 2007 to see how blood sugar levels predict health outcomes.

The study showed that patients with or without pre-existing diabetes who had high blood sugar were more likely to be hospitalised and were at greater risk of dying from any cause.

Patients should be reassured that heart failure patients who are admitted to A&E will have their blood sugar checked as standard procedure.

Maureen Talbot, our Senior Cardiac Nurse, said: “‘The findings of this study show that elevated blood sugar levels in a person with acute heart failure, even if they are not diabetic, is an indicator of future onset of diabetes, hospital admission or death.

“While this is an interesting finding, patients should be reassured that heart failure patients who are admitted to A&E will have their blood sugar checked as standard procedure. 

"If their blood sugar is high, they will receive appropriate treatment.”
