| Video Discription | Atherosclerosis & Cholesterol. Are LDL, HDL and triglycerides good measures of atherosclerosis risk? A look at atherosclerosis, cholesterol and tips to dodge a heart attack. how to dodge a heart attack? let's look at atherosclerosis aka plaque and best lab tests to prevent it LDL? LDL-cholesterol? people call them both LDL. HDL? VLDL? IDL… cholesterol is carried in our bloodstream by lipoproteins. lipoproteins are the buses and cholesterol is the passenger some get stuck in the artery wall. if there’s a lot of lipoproteins in the blood, over the years this forms plaque aka atherosclerosis plaque can block blood flow and cause angina (chest pain when the heart muscle doesnt get enough blood). plaque can also break and clot causing a heart attack lipoproteins: LDL (low dens lipoprotein). VLDL or very low density lipoprotein LDL and VLDL are the same family. there’s other families of lipoproteins but these are the main ones that cause atherosclerosis this family of lipoproteins includes LDLs, VLDLs etc. they all carry apoB. we can measure these lipoproteins by measuring apoB lipoproteins cause atherosclerosis but blood work measures LDL-cholesterol (cholesterol in LDL) and triglycerides. they estimate risk of atherosclerosis European atherosclerosis society: LDL-cholesterol is a satisfactory surrogate for LDL particle number. so high LDL-cholesterol is a red flag. and same for triglycerides online: focus on LDL-cholesterol, ignoring triglycerides vs focus on triglycerides & ignoring LDL-cholesterol both markers of lipoproteins that cause atherosclerosis. risk of atherosclerosis determined by apoB particles regardless of lipids… benefit of lipid-lowering (so, lowering cholesterol or triglycerides) proportional to reduction in apoB regardless of the change in LDL-Cholesterol or triglycerides if LDL-cholesterol is high, number of LDL lipoproteins is often high. high LDL-cholesterol is a red flag and indicates high apoB cholesterol/triglycerides reflect lipoproteins. exceptions: lipoproteins rule, not LDL-cholesterol or triglycerides normal number of lipoproteins, normal apoB + high LDL-cholesterol/triglycerides=normal risk high lipoproteins, high apoB + normal cholesterol/triglycerides= high risk of atherosclerosis LDL-c/triglycerides are like the check engine light. checking engine directly = apoB HDL-cholesterol aka ‘good cholesterol’? people with high HDL-cholesterol tend to have less heart disease causal relationship? raise HDL-cholesterol specifically analysis: raising HDL-cholesterol did not lower atherosclerosis risk. raising HDL-cholesterol offers no CV protection “the effects on cardiovascular disease of foods or nutrients cannot be judged from changes in HDL cholesterol” HDL-cholesterol: correlates. doesn’t cause benefit. same for ratios using hdl-cholesterol raising my HDL-cholesterol does nothing for risk high HDL-cholesterol = distraction key concepts to dodge atherosclerosis and a heart attack: 1) high apoB buses, apoB lipoprots = risk of atherosclerosis 2) We can measure apo B lipoproteins by measuring apoB 3) LDL-cholesterol and triglycerides are useful but not perfect 4) careful with HDL-cholest improving our lipids including apoB: diet. more detail on lipids in your blood work Connect with me: Facebook: https://www.facebook.com/DrGilCarvalho/ Twitter: https://twitter.com/NutritionMadeS3 Animations: Even Topland @toplandmedia References: https://academic.oup.com/eurheartj/article/38/32/2459/3745109 https://jamanetwork.com/journals/jama/article-abstract/2768850 https://jamanetwork.com/journals/jamacardiology/article-abstract/2753612 HDL-cholesterol:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4103514/ https://www.ahajournals.org/doi/pdf/10.1161/CIRCULATIONAHA.119.044687 Disclaimer: The contents of this video are for informational purposes only and are not intended to be medical advice, diagnosis, or treatment, nor to replace medical care.
