Hypertension is the most important component of metabolic syndrome in the association with ischemic heart disease in Taiwanese type 2 diabetic patients.
BACKGROUND
To evaluate the association between components of metabolic syndrome (MS) and ischemic heart disease (IHD) in Taiwanese patients with type 2 diabetes mellitus (T2DM).


RESULTS
A total of 1,296 (604 men and 692 women) subjects with T2DM aged 62.5+/-11.7 (14-87) years were studied. MS was defined using the World Health Organization modified criteria and included more than 2 of hypertension, obesity, dyslipidemia and microalbuminuria. IHD was diagnosed through history or ischemic electrocardiogram according to the Minnesota codes. Results showed that MS was present in 76.2% and IHD in 36.3% of the patients, respectively. MS increased with age for both sexes, but there was no difference between men and women in the age groups of <45, 45-54 and 55-64 years. However, the prevalence of MS was significantly higher in women (87.7% vs 78.0%) in the age group>or=65 years. IHD prevalence was significantly higher in patients with MS, hypertension, dyslipidemia and obesity (p<0.01), and was higher with borderline significance for microalbuminuria (0.05<p<0.1). The respective age-adjusted odds ratios were 3.61 (2.57-5.08), 7.10 (5.38-9.38), 1.70 (1.32-2.18), 1.75 (1.33-2.28), and 1.11 (0.88-1.41).


CONCLUSIONS
The prevalence of MS in subjects with T2DM is high and increases with age. The impact of different risk factors on IHD is diverse, with hypertension being the most important.
