[Study on the prevalence of diabetes mellitus among acute coronary syndrome inpatients in a multiprovincial study in China].

OBJECTIVE

To demonstrate the current prevalence and treatment status of diabetes mellitus (DM) among inpatients with acute coronary syndrome (ACS) in China.

METHODS

Sixty-four hospitals, including 32 secondary hospitals and 32 tertiary hospitals were selected for baseline survey. Fifty inpatients diagnosed with ACS were recruited consecutively from hospitals participated in this study. This paper focused on the prevalence and treatment status of DM among inpatients with ACS.

RESULTS

(1) Clinical data of 3223 inpatients (average age 65 +/- 11) with ACS were collected during baseline survey, including 2183(67.7%) males and 1040 (32.3%) females. Among them, 39.8% were diagnosed as ST-segment elevation myocardial infarction (MI), 9.2% as non-ST-segment elevation MI, 51.0% as unstable angina, and 27.1% with ACS history. (2) DM was found in 22.6% ACS patients. The prevalence rate of DM was higher in female (26.3%) patients than that in males (20.8%). The rate of DM was the highest (28.0%) in northeast area and lowest (17.7%) in southwest among 7 geographic districts (north, east, south, central, northeast, northwest and southwest parts of the country). Significant difference was observed among these areas. (3) Rate of awareness on DM was 73.1% among patients with DM, with significant differences among various areas. Treatment rate was 62.1% among patients with DM, with the highest (88.6%) seen in northwest and the lowest (78.4%) in central part of China. (4) Rates of prevalence (27.1%), awareness (82.3%) and treatment (86.7%) of DM were higher in recurrent ACS patients than in those without ACS history.

CONCLUSION

Nearly one-forth of the ACS inpatients were having DM, and 15% of the patients with known DM were not on anti-diabetic treatment. It is essential to pay more attention on the treatment of DM for the purpose of secondary prevention on cardiovascular disease.
