Q&A: Are Everyday Microplastics Fueling Heart Disease?
New research from the University of California, Riverside suggests microplastics may directly accelerate heart disease — especially in males.
Here’s what the study uncovered, explained as simple Q&A.
Q: What exactly are microplastics?
A: Microplastics are tiny plastic particles released from:
Food packaging
Clothing and textiles
Household plastics
Industrial waste
Can Decreasing Homocysteine with L-Methylfolate + Active B-Vitamins Help Prevent Atherosclerosis and Reduce Plaque?
Cardiovascular prevention prioritizes proven interventions: cholesterol management, blood pressure control, smoking cessation, and lifestyle optimization. However, homocysteine is an additional modifiable risk factor—an amino acid linked to endothelial dysfunction and thrombosis. Supplements supplying the active cofactors for homocysteine metabolism—L-methylfolate (5-MTHF), methylcobalamin (active B-12), and pyridoxal-5-phosphate (P-5-P, active B-6)—reliably lower homocysteine levels. This Q&A explains the mechanism, the evidence regarding cardiovascular outcomes, product quality verification, and clinical integration.
Coronary Plaque Regression, the Lumen Paradox, and Vascular Remodeling in Athletes: Integrating Pharmacologic and Whole-Food, Plant-Based Strategies
Background: Coronary atherosclerosis, long thought to be an inexorably progressive disease, is now recognized as biologically reversible under specific metabolic and inflammatory conditions. Imaging studies using intravascular ultrasound (IVUS), coronary computed tomography angiography (CCTA), and quantitative coronary angiography (QCA) consistently demonstrate that aggressive lipid lowering or comprehensive lifestyle change can induce measurable regression of plaque burden. However, luminal area often fails to expand in parallel—a phenomenon termed the lumen paradox. For endurance athletes, who rely on high coronary flow reserve and robust endothelial responsiveness, understanding this paradox is crucial.
How Does Age Affect Atherosclerosis? A Q&A Explainer
Does the risk of atherosclerosis increase as we age? Yes. Atherosclerosis is considered a disease of aging. The likelihood and severity of plaque buildup in the arteries increase with age, even when other risk factors such as smoking, high cholesterol, or hypertension are controlled.
Reversal of Coronary Atherosclerosis: Mechanistic Insights from Human and Primate Studies
Coronary atherosclerosis can regress under defined conditions. Serial intravascular ultrasound (IVUS) and coronary computed tomography angiography (CCTA) studies show that intensive low-density lipoprotein cholesterol (LDL-C) reduction via high-intensity statins, PCSK9 inhibitors, and, in selected settings, icosapent ethyl, can shrink plaque volume. Paradoxically, the arterial lumen often remains unchanged or may even narrow due to reverse or constrictive remodeling. Complementary lifestyle trials such as the Ornish study demonstrated angiographic regression driven primarily by improved endothelial and vasomotor function.
