Regarding the importance of cardiovascular disease in the health of societies, Hyperlipidemia is considered as an important risk factor. One of the case recently put forward in the fat profile, is high TG (triglycerides) and low HDL-C (High Density Lipoprotein). Nowadays, we believe that TG without the presence of low HDL-C is not considered as a risk factor for cardiovascular disease. So it was decided to perform a descriptive study to define the prevalence of this syndrom, like other risk factors, in urban population of Isfahan. Samples were selected by random sampling method and the sample size, to have reliability of 95%, was about 1200 from the people over 20 year old in 6 age groups and 2 sexes. After inviting the people while going fast (about 14 hours), a questionnaire including perfect identifications was filled and blood factors include total cholesterol, TG, LDL-C (LOW Density Lipoprotein), HDL-C and F.B.S (Fasting Blood Sugar) were measured. Then the statistical analyzing of data was done to define the relation between TG and HDL-C. Regarding the coefficient of correlation and P.value <0.05 in different age and sex groups (except over 70 years old group which was not significant) was defined that TG has an inverse relation to HDL-C and the prevalence in the urban population of Isfahan is 19.7%. Results got from studying the relation between TG serum level and high LDL/HDL fraction (equal or more than five) showed that the more TG gets, the more the fraction is and regarding to its prevalence (11.6%) in Isfahan. It can be a risk factor for cardiovascular disease. So regarding the high prevalence of High TG and low HDL-C syndrome, treating this syndrome can be considered as one of the primary prevention methods. To fufil the latter goal firstly the syndrome must be identified and the related patients must be treated. So the patients with high TG must be tested for HDL-C and LDL-C too. And secondly therapeutic actions to increase HDL-C and to decrease TG level must be done.
