Nature Reviews Cardiology, Published online: 18 November 2024; doi:10.1038/s41569-024-01100-3 Cholesterol crystals (CCs) have a pathogenic role in various cardiovascular diseases, particularly atherosclerosis.
Atherosclerosis, or the buildup of plaque in the arteries, develops when low-density lipoprotein cholesterol (LDL-C) enters the blood vessel walls through dysfunctional endothelial cells (EC), leading to the formation of plaques.
Our risk of developing atherosclerosis -- 'furring' of the arteries -- can begin much earlier in life than was previously thought, highlighting the need to keep cholesterol levels low even when we are young, new research has discovered.
Two new studies document that, despite similar overall exposure to high-fat diet over a lifetime, an intermittent consumption of high-fat diet early in life accelerates atherosclerosis compared with continuous consumption of a high-fat diet. The mechanisms for accelerated atherosclerosis include reprogramming of macrophages and neutrophils.
A new study reveals that immune cells in the liver react to high cholesterol levels and eat up excess cholesterol that can otherwise cause damage to arteries. The findings suggest that the response to the onset of atherosclerosis begins in the liver.
Here, we examined the therapeutic potential of itaconate in atherosclerosis. Deletion of Acod1 in myeloid cells exacerbated inflammation and atherosclerosis in vivo and resulted in an elevated frequency of a specific subset of M1-polarized proinflammatory macrophages in the atherosclerotic aorta.
Background Inflammation is pivotal to the progression of atherosclerosis. Cholesterol crystals (CCs) that grow and enlarge within the plaque core can cause plaque rupture and trigger inflammation as they deposit into the atherosclerotic bed. Method Different dosages of colchicine mixed with cholesterol (0.05–5 mg/ml/g
BackgroundLow-Density Lipoprotein Cholesterol (LDL-C) is the primary lipid therapy target for coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI). Employing Multivariate Cox regression analysis, we assessed the correlation between RLP-C and NTLs progression.
This interaction led to increased cytosolic cholesterol in macrophages and changes in expression of lipid metabolism genes consistent with increased cholesterol uptake.
METHODS:The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing.
Introduction The progression of coronary atherosclerosis is an active and regulated process. The Wnt signaling pathway is thought to play an active role in the pathogenesis of several cardiovascular diseases; however, a better understanding of this system in atherosclerosis is yet to be unraveled.
Researchers have identified a new pathway that contributes to cardiovascular disease associated with high levels of niacin, a common B vitamin previously recommended to lower cholesterol. The team discovered a link between 4PY, a breakdown product from excess niacin, and heart disease.
This year, the cholesterol charity took on an international theme, looking at the global cardiovascular disease (CVD) prevention picture. HEART UK held its 37 th Annual Medical and Scientific Conference between 10 th –12 th July.
BackgroundResolvin D2 (RvD2) has been reported to protect against the development of atherosclerosis in animal models. Mediation analysis was used to test the indirect effect of serum cholesterol indicators on the association between RvD2 and ASCVD probability. Journal of the American Heart Association, Ahead of Print. P<0.001).
Positive correlations were identified with age, systolic blood pressure, a history of hypertension, male gender, and total cholesterol. By stressing the significance of managing cholesterol levels, especially HDL, our findings provide actionable insights for CAS prevention.
13, 2024 – The traditional lipid panel may not give the full picture of cholesterol-related heart disease risk for many Americans, according to a study led by UT Southwestern Medical Center researchers and published in JAMA Cardiology. Ann Marie Navar, M.D., tim.hodson Thu, 08/15/2024 - 10:32 Aug. population. Physicians following U.S.
cholesterol for 16 weeks. Atherosclerosis was evaluated at the endpoint of experiments. Plasma lipid levels, lipoproteins, and apolipoproteins were analyzed. Notably, both male (2.1-fold fold increase) and female (1.6-fold fold increase) apoE KO rabbits exhibited a significantly augmented aortic lesion area compared to WT controls.
The abnormal low-density protein cholesterol (LDL-C) level in the development of atherosclerosis is often comorbid in individuals with type 2 diabetes mellitus(T2DM). This study aimed to investigate the aggrav.
BackgroundPlaque progression (PP) is critical between subclinical atherosclerosis and plaque rupture. Small dense lowdensity lipoprotein cholesterol (sdLDLC) is considered as the most atherogenic lipoprotein. Journal of the American Heart Association, Ahead of Print.
Heart Rhtyhm recently published two large cohort studies, Chen et al, 2024, “Low remnant cholesterol and the subsequent risk of new-onset atrial fibrillation: A prospective cohort study” (1) and Ouyang, et al 2024, “Remnant Cholesterol and New-onset Atrial Fibrillation: The Atherosclerosis Risk in Communities Study” (2).
We all want to be heart-healthy and ensuring our cholesterol levels are in the normal range is one of the most critical steps. High cholesterol can increase your risk of severe conditions like heart disease and heart attacks. Continue reading to learn four heart-healthy habits that can improve your cholesterol.
Presence of atherosclerosis with LDL-C and HBA1c in the ‘normal range’ What the above graph shows is that for those with an LDL-C of 3.4 ‘Normal’ levels of risk factors such as blood pressure, cholesterol or blood glucose levels are often FAR from optimal. So far, two things should be very clear. JAMA Cardiol.
CCR5, a chemokine receptor, has been associated with both immunosuppressive and inflammatory phenotypes, however, the possible role of CCR5 pertaining to MDSCs in the development of atherosclerosis has not been elucidated yet. Possibly this dysfunctionality contributes to the development and progression of CVD including atherosclerosis.
The enlightened thinking is, if LDL and HDL are brought around the same level of around 50mg , good and evil will have level playing ground , hoping goodness will win over the evil.Our vast vascular tree will have perfect lipid house keeping system and atherosclerosis will cease to occur.( Final message.
Taking a long-term view of cardiovascular disease prevention is an attractive strategy since atherosclerosis begins early in life and progresses over decades. Lowering low-density lipoprotein (LDL) cholesterol levels and improving lifestyle habits are mainstay strategies for reducing the risk of cardiovascular disease.1
Atherogenic index of plasma (AIP), a novel logarithmic index that combines fasting triglyceride and high-density lipoprotein cholesterol concentrations, is associated with the burden of atherosclerosis.
BackgroundAortic stenosis has pathophysiological similarities with atherosclerosis, including the deposition of cholesterol‐containing lipoproteins. The resulting cholesterol crystals activate the NLRP3 (NOD‐like receptor protein 3) inflammasome, leading to inflammation and cardiovascular diseases. per 100 person‐years,P=0.01).
It is triggered by atherosclerosis, which occurs when fatty deposits or cholesterol accumulates… Source PAD is a serious condition affecting circulation and blood vessels, causing them to narrow from plaque buildup in the arteries and blocking blood flow to the extremities, typically the legs and feet.
The fundamental characteristic of atherosclerosis is when a cholesterol particle becomes trapped in the artery wall. It is the inflammatory response to this particle retention that causes the formation of atherosclerosis 1. Lipoprotein particles entering the subintimal space causing atherosclerosis. TG = Triglycerides.
Conclusions:There is an L-shaped association between NHHR levels and atherosclerosis in adults in the United States, and controlling NHHR is clinically important for reducing the risk of developing atherosclerosis. The cutoff value was 2.13, and in the hypertensive population, the cutoff value was 1.93.Conclusions:There
Background Inflammation and lipid infiltration play crucial roles in the development of atherosclerosis. The monocyte to high-density lipoprotein cholesterol ratio (MHR) was identified as a stronger independent risk factor for CHD.
Statins are the primary drugs for treating hyperlipidemia or atherosclerosis, yet some patients remain unresponsive to them, and pregnant women are prohibited from taking statins. IntroductionThe incidence of metabolic disorders during pregnancy is increasing year by year, with diseases including hypertension and hyperlipidemia.
Atherosclerosis, also called " hardening of the arteries, " occurs when fat, cholesterol and other substances are deposited in the walls of the arteries. Atherosclerosis is a common disease. These deposits are called plaques. Over time, these plaques can narrow or completely block arteries and cause problems throughout the body.
METHODS:The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing.
Newly included risk factors— untreated vision loss and high LDL cholesterol —underscore the critical role of these elements in maintaining cognitive health. The Cholesterol Connection Cholesterol’s recognition as a risk factor for dementia marks a pivotal advancement in understanding, preventing, and delaying cognitive decline.
Regarding blood lipids, there were no changes total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, or apolipoprotein A1 (ApoA1) or apolipoprotein-B (ApoB). LDL and ApoB — which play an obligate and causal role in the development of atherosclerosis — weren’t affected by exercise.
Atherosclerosis, or the buildup of plaque in the arteries, develops when low-density lipoprotein cholesterol (LDL-C) enters the blood vessel walls through dysfunctional endothelial cells (EC), leading to the formation of plaques.
The fundamental role of qualitative alterations of lipoproteins in the early development of atherosclerosis has been widely demonstrated. However, the corresponding studies are scarcer in the field of ischemic stroke, despite carotid arteriosclerosis progression underlies at least 20% of ischemic strokes.
I do apologise for being direct, but this issue is one of the most frequent barriers I encounter to initiating cholesterol-lowering therapy. At the exact same time, cholesterol concentrations are also at their lowest. At the exact same time, cholesterol concentrations are also at their lowest. Let’s break this down.
Every lipoprotein particle has one APO B protein. ( **Please note the B ) When we measure APO B levels, this is what we are measuring to give an estimate of the number of cholesterol particles and the subsequent risk of cardiovascular disease. APO E is also centrally involved in cholesterol metabolism. Here’s how. What to do?
Several mechanisms have been proposed to account for the association between HDAC9 and atherosclerosis including alterations in the inflammatory response and cholesterol efflux and endothelial-mesenchymal transition. Indirect data support such an approach in man.
