Hypoglycaemia, Abnormal Lipids, and Cardiovascular Disease among Chinese with Type 2 Diabetes

Abstract EN

We recruited a group of 6713 consecutive Chinese patients with T2D but normal renal and liver function who were admitted to one of 81 top tertiary care hospitals in China.

Mild hypoglycaemia was defined as having symptomatic hypoglycaemia in one month before hospitalization.

Severe hypoglycaemia was defined as having hypoglycaemia that needed assistance from other people in three months before hospitalization.

Prior cardiovascular disease (CVD) was defined as having coronary heart disease, stroke, or peripheral arterial disease.

Of 6713 patients, 80 and 304 had severe and mild hypoglycaemia episodes, respectively, and 561 had CVD.

Patients with severe and mild hypoglycaemia episodes were more likely to have prior CVD (32.5% versus 16.5% versus 7.7%, P < 0.0001 ).

Both mild and severe hypoglycaemia were associated with increased risk of CVD (adjusted odds ratios (ORs): 2.64, 95% CI: 1.85–3.76 for mild hypoglycaemia; 6.59, 95% CI: 3.79–11.45 for sever hypoglycaemia) than those patients free of hypoglycaemia.

Further adjustment for lipid profile did not change these two ORs.

In the same way, the ORs of lipid profile for CVD were similar before and after adjustment for hypoglycaemia.

We concluded that hypoglycaemia and lipid profile were independently associated with increased risk of CVD.
