Conclusions Plant-based diets are associated with decreased total cholesterol , low-density lipoprotein cholesterol , and high-density lipoprotein cholesterol , but not with decreased triglycerides .
Context Although a recent meta- analysis of r and omized controlled trials showed that adoption of a vegetarian diet reduces plasma lipids , the association between vegetarian diets and long-term effects on plasma lipids has not been subjected to meta- analysis .
Objective The aim was to conduct a systematic review and meta- analysis of observational studies and clinical trials that have examined associations between plant-based diets and plasma lipids .
The Effects of an Intensive Lifestyle Modification Program on Carotid Artery Intima-Media Thickness: A Randomized Trial
Purpose . This study evaluated the effect of the Dr. Dean Ornish Program for Reversing Heart Disease on cardiovascular disease as measured by the intima-media thickness of the common carotid artery and compared this effect to outcomes from patients participating in traditional cardiac rehabilitation . Design . R and omized clinical trial . Setting . SwedishAmerican Health System . Subjects . Ninety three patients with clinical ly confirmed coronary artery disease were r and omly assigned to the intervention ( n = 46 ) or traditional cardiac rehabilitation ( n = 47 ) . Intervention . Dr. Dean Ornish Program for Reversing Heart Disease . Measures . Ultrasound of the carotid artery and other cardiovascular risk factors were measured at baseline , 6 , and 12 months . Analysis . Intent-to-treat analysis . Results . There was no significant reduction in the carotid intima-media thickness of the carotid artery in the Ornish group or the cardiac rehabilitation group . Ornish Program participants had significantly improved dietary habits ( p < .001 ) , weight ( p < .001 ) , and body mass index ( p < .001 ) as compared with the rehabilitation group . The decrease in the number of patients with angina from baseline to 12 months was 44 % in Ornish and 12 % in cardiac rehabilitation . Conclusions . The Ornish Program appears to causes improvements in cardiovascular risk factors but does not appear to change the atherosclerotic process as it affects the carotid artery
