Obesity is commonly cited as a risk factor for the development of coronary heart disease (CHD). Epidemiologic studies tend to support this contention, particularly those focusing on patients with central obesity. Such studies however, are imprecise and prone to misclassification bias. Angiographic and post mortem studies have demonstrated little or no correlation of total fat mass and coronary atherosclerosis except in those with abdominal obesity. There is a strong association of obesity, particularly central obesity, and traditional risk factors for CHD such as hypertension, type II diabetes mellitus, and dyslipidemia. There may also be an association between obesity and several nontraditional risk factors such as hyperhomocystinemia, elevated Lp(a) levels and factors that increase thrombogenesis. Obesity may also alter endothelial function. Weight loss, although associated with favorable modification of multiple risk factors for CHD, has not been shown to independently and definitively reduce CHD risk.

Young adults with abdominal obesity are liable to have subclinical atherosclerosis that may contribute to an increased risk of cardiovascular disease later in life. This study aims to evaluate subclinical atherosclerosis and its possible correlation with some inflammatory and biochemical markers in Egyptian young adult males with abdominal obesity. The study includes 50 young adult males (age range: 19-29 years) divided into two groups. Group 1 comprises 20 non-obese subjects (controls). Group 2 comprises 30 apparently healthy obese subjects. Carotid intima media thickness (carotid-IMT) was estimated using B-mode ultrasonography of the common carotid arteries, and abdominal ultrasonography was performed to assess the presence of a fatty liver. Laboratory investigations included fasting levels of serum glucose, triglycerides (TG), cholesterol (total [TC], high-density [HDL-cholesterol] and low-density [LDL-cholesterol] lipoprotein fractions), high-sensitivity C-reactive protein (hs-CRP), neopterin, lipoprotein-a (Lp[a]), gamma glutamyl transferase (GGT), aspartate and alanine aminotransferases (AST, ALT), plasma plasminogen and fibrinogen. Results showed that carotid IMT, serum hs-CRP, neopterin, Lp(a), fibrinogen, plasminogen, TC, TG, LDL-cholesterol and liver enzymes were significantly elevated (P<0.001) in the obese group compared to controls. All obese subjects showed evidence of fatty liver. A significant positive correlation was found between carotid-IMT and body mass index, waist circumference, waist/hip ratio, cholesterol, triglycerides, neopterin, hs-CRP AST, ALT and GGT. Elevated serum levels of inflammatory biomarkers and increased ALT, AST and GGT, and non-alcoholic fatty liver disease biomarkers may be useful predictors of subclinical atherosclerosis.

Trans-fatty acids (TFAs), products of partial hydrogenation of vegetable oils, have become more prevalent in our diet since the 1960s, when they replaced animal fats. TFAs also occur naturally in meat and dairy products from ruminants. There is growing evidence that dietary trans-fatty acids may increase the risk of metabolic syndrome. Several studies have demonstrated adverse effects of TFAs on plasma lipids and lipoproteins. In dietary trials, trans-fatty acids have been shown to raise the total cholesterol/HDL cholesterol ratio and Lp(a) levels in blood. Moreover, a high intake of TFAs has been associated with an increased risk of coronary heart disease. Prospective cohort studies have shown that dietary trans-fatty acids promote abdominal obesity and weight gain. In addition, it appears that TFA consumption may be associated with the development of insulin resistance and type 2 diabetes. The documented adverse health effects of TFAs emphasise the importance of efforts to reduce the content of partially hydrogenated vegetable oils in foods.
