OBJECTIVETo observe the difference of serum lipid levels between patients with coronary heart disease(CHD) and those without,in Zhejiang province.

METHODSAccording to coronary angiogram, 602 patients were divided into two groups as group 1 (vessel stenosis > or =50% luminal diameter narrowing of at least one major coronary artery), group 2 (no vessel stenosis or vessel stenosis <50% luminal diameter narrowing ). Their serum triglyceride (TG), total cholesterol (TC), lower density lipoprotein cholesterol (LDL-C), higher density lipoprotein cholesterol (HDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) were measured and analysed.

RESULTSSerum lipid levels of the two groups were all close to the proper scopes of Principles for the prevention of dyslipidemia recommended by dyslipemia group of the editorial board of Chinese Journal of Cardiology. Data also showed that levels of serum TC, LDL-C and non-HDL-C in group 1 were alightly higher than those in group 2 (4.70 mmol/L +/- 1.22 mmol/L vs. 4.49 mmol/L +/- 0.96 mmol/L, 2.63 mmol/L +/- 1.00 mmol/L vs. 2.44 mmol/L+/- 0.77 mmol/L, 3.45 mmol/L+/- 1.14 mmol/L vs. 3.22 mmol/L+/- 0.92 mmol/L, P < 0.05, P< 0.01, respectively).

CONCLUSIONHyperlipidemia was not a inherent characteristic for CHD patients in Zhejiang province.
