Abstract

Objective:

The aim of this study is to analyse the prevalence of diagnosed or undiagnosed diabetes in Bulgarian high risk patients during the period 2007-2014.

Design and method:

We analyse the data from Bulgarian cohorts of high risk patients included in both surveys EUROASPIRE (European Action on Secondary and Primary Prevention by Intervention to Reduce Events) III and IV, held in 2007 and 2014. The protocols of EUROASPIRE III and IV trials comprise standard questionnaires used by all countries to determine the patient health status.

Results:

The prevalence of diagnosed or undiagnosed diabetes (self-reported diabetes or fasting glucose >7 mmol/L) among high risk patients in EUROASPIRE III is 48.9% in men and 44.7% in women (on average 45.7%). The prevalence of undiagnosed diabetes among non-diabetic patients (fasting glucose >7 mmol/L) is 20.0% in men and 17.6% in women (on average 18.1%). 60.7% of the patients with self-reported diabetes have HbA1c<7.0% and 42.9% of them have HbA1c<6.5%. The prevalence of diagnosed or undiagnosed diabetes among high risk patients in EUROASPIRE IV is 60%. The prevalence of undiagnosed diabetes (fasting glucose >7 mmol/L and/or HbA1c >6.5%) among non-diabetic patients is 40%. 65% of the patients with self-reported diabetes have HbA1c<7.0% and 45% of them have HbA1c<6.5%.

Conclusions:

About 1/3 of the high risk patients have diabetes. We found an increase of the undiagnosed diabetes among them. Most of the patients with self-reported diabetes do not reach blood glucose under target levels.
