While advances in treatment have reduced mortality in some regions, the atherosclerosis prevention remains challenging. This shift results from an epidemiologic transition: as infectious diseases decline, chronic conditions like atherosclerosis dominate.
Nature Reviews Cardiology, Published online: 18 October 2024; doi:10.1038/s41569-024-01095-x Consumption of a high-fat diet leads to the progressive growth of atherosclerotic lesions. The mechanisms for accelerated atherosclerosis include reprogramming of macrophages and neutrophils.
Atherosclerosis is the major contributor to cardiovascular mortality worldwide. Diet-induced metabolic abnormalities including obesity, hyperglycemia, dyslipidemia, insulin resistance (IR), and non-alcoholic fatty liver disease are considered atherogenic risk factors.
Nature Reviews Cardiology, Published online: 26 March 2025; doi:10.1038/s41569-025-01149-8 A study published in Nature has identified two transmembrane G protein-coupled receptors that mediate extracellular-to-intracellular ceramide signalling and shows that blocking these receptors alleviates the atherosclerosis that is induced by a high-fat diet (..)
Over the past few decades, scientists have generated a pile of evidence suggesting that a diet rich in saturated fats is enough to cause heart diseases. Besides other problems like diabetes and atherosclerosis, saturated fats have also been linked to life-threatening arrhythmias.
High-protein diets are often advocated for building muscle, losing weight, and optimizing body composition. Eating this amount of protein means your diet will comprise about 11% of calories from protein, leaving fat and carbs to fill the gaps. In simpler terms: In mice, a high-protein (and hence high-amino-acid) diet activates mTORC1.
While much attention is given to modifiable risk factors such as diet, exercise, and smoking, the role of genetics in heart disease is equally critical yet less understood by the general public. Inflammation: Genetic variations can make some people more prone to chronic inflammation, which contributes to the development of atherosclerosis.
This condition, called atherosclerosis, narrows the arteries, restricting blood flow and increasing the risk of heart attacks and strokes. This condition, known as left ventricular hypertrophy, can lead to heart failure if untreated. Limit your intake of salt, processed foods, and sugary drinks.
Share While the average Western male and female will develop advanced coronary artery disease by age 55 and 66, respectively, 85% of the Tsimane tribe population over 40 had no evidence of advanced atherosclerosis 2. Coronary atherosclerosis, as evidenced by an abnormal CAC score, is a measure of advanced plaque. In my view.
Here, we show that high fat consumption in mice leads to the accumulation of lipid droplets in endothelial cells throughout the organism and that lipid droplet accumulation in endothelium suppresses endothelial nitric oxide synthase (eNOS), reduces NO production, elevates blood pressure, and accelerates atherosclerosis.
Atherosclerosis was evaluated at the endpoint of experiments. cholesterol for 16 weeks. Plasma lipid levels, lipoproteins, and apolipoproteins were analyzed.
Background:Most ischemic strokes are caused by atherosclerosis. Apolipoprotein E (ApoE) regulates lipid metabolism, and its deficiency is associated with dyslipidemia and atherosclerosis. Poor dietary habits promote the onset of atherosclerosis. Stroke, Volume 55, Issue Suppl_1 , Page ATP300-ATP300, February 1, 2024.
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.
More than 1/3 of the respondents correctly indicated the permissible amount of salt in the diet recommended by WHO; even larger percentage (86.3%) correctly indicated that limiting salt intake in the diet applies to both healthy and sick people. to even 53%.
Background:The current unmet needs for aspirin usage in atherosclerosis lie in its short half-life and narrow indication for anti-platelet effects. Daily aspirin intake is mandatory, and the anti-inflammatory effects of aspirin for atherosclerosis have not successfully translated to clinical practice.
Dysfunctional WAT drive chronic inflammation and facilitate atherosclerosis. Here, we combined the single-cell RNA sequencing technique with cell metabolic and functional assays on major WAT ATM subpopulations using a diet-induced atherosclerosis mouse model (Apoe-null). Interestingly, LAM increased 8.4-fold
Coronary Atherosclerosis There are multiple ways of describing coronary plaque: The degree of obstruction The composition of the plaque The thickness of the plaque wall (Cap) that separates the plaque from the inside of the blood vessel. Good nutrition (Not just a DASH diet, I suspect) changes plaque composition to safer, more stable plaque.
More than 90% of the Lp(a) level is influenced by variations in the genes controlling the Lp(a) particle production, 2 in which lifestyle interventions such as diet and exercise have no significant impact. 2022 Aug, 80 (9) 934946 Kronenberg F.
I am a fan of using low-carb diets for both weight loss and improving metabolic health. Low-carb diets have consistently shown benefits in improving these parameters 1. In the early 1970’s a group of 106 severely obese patients were put on a diet that resulted in an average weight loss of 63 Kg (139 lbs) over about one year 2.
Background:PCSK9, a key regulator of cholesterol metabolism, has been implicated in atherosclerosis. PCSK9 overexpression was induced via AAV injection, and mice were subjected to either a normal diet or HFD for 4 months. However, its potential role in vascular cognitive impairment and dementia (VCID) remains elusive.
Regular exercise, a balanced diet, and lifestyle choices such as not smoking and managing stress are all crucial for achieving and maintaining optimal cardiovascular health. The role of diet in cardiovascular health Diet plays a significant role in maintaining cardiovascular health.
a unique approach, we crossed DS model mice withApoE-null mice and fed them a high-fat diet (HFD) for 12 weeks to survey the effects of DS-related genes on atherosclerosis. The results were striking, with HFD-mediated increased LDL and triglyceride levels inApoE-null mice significantly reduced in the combined DS plusApoE-null mice.
Blood Vessels: Chronic stress can impair the function of the endothelium—the lining of blood vessels—potentially leading to atherosclerosis, a precursor to heart disease. Balanced Diet: A healthy diet can support overall health and help manage stress. Adequate Sleep: Good sleep hygiene can help regulate cortisol rhythms.
Low-density lipoprotein (LDL) or “bad cholesterol” can create plaque in your arteries, putting you at risk for health complications like atherosclerosis, heart disease and vascular issues. Reduce saturated fats and eliminate trans fats from your diet. You should also eliminate all trans fat from your diet.
LDL is obviously a target against atherosclerosis. While, the relationship between LDL and atherosclerosis is so intimate, funnily we have heaps of data that show South Asian population with tons & tons of plaque with normal LDL. Preamble 15 % of body weight is fat.
PAD is a serious, progressive cardiovascular disease primarily caused by a buildup of fatty plaque in the blood vessels, or atherosclerosis. This plaque narrows the blood vessels and reduces blood flow to the legs and feet, which may significantly impair physical function, walking performance and quality of life.
Dyslipidemia, characterized by an imbalance in lipids such as cholesterol, LDL-C, triglycerides, and HDL, can result from various factors, including diet, tobacco and alcohol use, a sedentary lifestyle, or genetic conditions like familial hypercholesterolemia.
A 69‐year‐old woman with a history of lung cancer, hypertension, chronic tobacco use, atherosclerosis, and known calcified plaque at the left carotid bifurcation on dual antiplatelet therapy presented with acute onset of expressive aphasia and right hemiparesis due to acute left CCAO. Post‐operatively, he had evacuation of neck hematoma.
A meta-analysis published in the Journal of Consulting and Clinical Psychology found that motivational interviewing effectively promoted behavior change across various health domains, including diet and exercise. Key contributions: Advanced cardiac imaging (e.g.,
1 In addition to genetic and behavioural risk factors (unhealthy diet, physical inactivity, and tobacco and alcohol abuse), inhaling airborne pollutants, such as fine particulate matter (<2.5 Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death worldwide, causing around 17.9
ICYMI On Wednesday, I published a post about the recent evidence on high-volume exercise and atherosclerosis in athletes. Not surprising given that diet and physical activity outside of the intervention didn’t change. Welcome to the Physiology Friday newsletter. Physiologically Speaking is a reader-supported publication.
Introduction Atherosclerosis is a chronic inflammatory disease caused by the deposition of lipids within the artery wall. Here, we sought to investigate the role of autophagy activation during atherosclerosis regression.
In a conventional Western diet model for 2 months, HEG1iECKOmice also showed an exacerbated atherosclerosis development in the arterial tree in both sexes and the aortic sinus in males but not in females. Circulation, Ahead of Print.
The amount of calcium in the blood vessels (known as arterial calcification), a marker of subclinical atherosclerosis, is higher in people with a short sleep duration. 14 One study of over 1,900 men found evidence that very short sleep duration predicts a higher burden of atherosclerosis in their coronary and femoral arteries.
Coronary artery calcium (CAC) is a measure of atherosclerosis and a strong predictor of cardiovascular disease. The Latest Evidence on Atherosclerosis in Athletes The risk factor component is yet unexplored—how do risk factors other than training contribute to elevated CAC in endurance athletes?
Cholesterol aggregation in dendritic cells (DCs) triggers an inflammatory response and accelerates the development of atherosclerosis (AS). Resveratrol (RES), a natural compound with anti-inflammatory and cholesterol metabolism regulatory properties, has been shown to influence the maturation and inflammatory functions of DCs.
