Blood Sugar Levels and Coronary Artery Disease

Coronary arteries feed your heart muscle, and when they become blocked, your heart does not get enough oxygen, causing you chest pain and sometimes permanent damage. The condition is known as coronary artery disease, and Type 2 diabetics are at a known risk.

Researchers looked at HbA1c levels and compared them with cases connected with cardiovascular disease to discover what HbA1c levels put diabetics at high risk for heart disease.

Their study, published in 2012 in the journal¬†Endocrinology of Poland,¬†included…


  • 211 patients with disease of the coronary arteries, and
  • 160 healthy participants, ranging in age from 34 to 38.


It was found..


  • the people with cardiovascular disease had an average HbA1c level of 6.1 per cent, while
  • healthy people had an average HbA1c level of 4.7 per cent.


Participants with HbA1c levels of 6.52 per cent or higher, were at a high risk for cardiovascular disease, and predicting this disease in participants with that HbA1c level or higher, was about 75 per cent accurate.

From these results, it was concluded high HbA1c levels could play an important part in the development of cardiovascular or coronary artery disease.

The good news is, according to the U.S. National Health and Nutrition Examination survey, good care appears to lower the risk of coronary artery disease in people diagnosed with Type 2 diabetes.
