Trans-fatty acid patterns in patients with angiographically documented coronary artery disease
Abstract
The plasma trans-fatty acids of 47 patients with angiographically documented coronary artery disease were compared with those of 56 reference subjects using high-resolution capillary column gas-liquid chromatography to test the hypothesis that trans-fatty acid intake is a risk factor for cardiovascular disease. Individual and total trans-fatty acids were higher in patients than in reference subjects (1.38 vs 1.11% for total trans-fatty acids, p < 0.003; 0.40 vs 0.31% for palmitoleic acid trans, p < 0.001; and 0.28 vs 0.22% for linoleic acid trans, p < 0.007). High-density lipoprotein (HDL) cholesterol and HDL cholesterol/total cholesterol were negatively correlated (r = -0.29, p < 0.004; and r = -0.35, p < 0.001, respectively), whereas triglycerides, total cholesterol and low-density lipoprotein cholesterol were positively correlated (r = 0.47, p < 0.001; r = 0.22, p < 0.03; r = 0.20, p < 0.05, respectively) with palmitoleic acid trans. The correlations were similar and significant for linoleic acid trans, but less strong for total trans-fatty acids (which is more difficult to measure and has greater variability). Saturated and trans-fatty acids and total cholesterol are positively associated, whereas HDL/total cholesterol and ...Continue Reading

Cardiovascular Diseases: Risk Factors
Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
Cardiovascular Risk Prediction
Cardiovascular risk prediction models based on classical risk factors identified in epidemiological studies are useful in primary prevention of cardiovascular disease in individuals. Here is the latest research.
