Calcium-free hearts can still be at risk: LDL history matters

Calcium-free hearts can still be at risk: LDL history matters

A zero coronary calcium score often signals low short-term risk, but in a CARDIA analysis of young-to-middle-aged adults, higher cumulative LDL-C exposure over the prior 25 years predicted more cardiovascular events even when CAC was zero. At age ~50, those in the highest LDL-C exposure quartile had about a 3.36-fold higher adjusted risk than the lowest, though absolute event rates remained modest (roughly 3.9% vs 1.3% over about a decade). This means zero CAC is reassuring but must be interpreted in the context of age, sex, family history, and lifelong LDL exposure.

Microplastics Found in Every Artery Sample, Study Raises Cardiovascular Questions

Microplastics Found in Every Artery Sample, Study Raises Cardiovascular Questions

A Chinese-led study analyzed 17 arterial samples from surgical procedures and detected microplastics in all of them, with higher levels in arteries containing fatty plaques (coronary and carotid) than in the aorta; PET was the dominant plastic. While the findings raise concerns about potential cardiovascular effects, the researchers caution that a direct causal link isn’t proven and call for further study, alongside other 2024 findings that microplastics may associate with arterial plaques and stroke risk.

Microplastics in Carotid Plaques Linked to 4.5× Higher Risk of Heart Events

Microplastics in Carotid Plaques Linked to 4.5× Higher Risk of Heart Events

A 2024 NEJM study found microplastics and nanoplastics embedded in the carotid plaque of 58% of patients; those with plastic in their plaque were about 4.5 times more likely to have a heart attack, stroke, or death within 34 months than those with plastic-free plaque, with inflammation and plaque destabilization proposed as mechanisms. Causality isn’t proven and replication is underway in New Mexico and elsewhere to determine if microplastics are a modifiable cardiovascular risk factor.

Celebrity death spotlights atherosclerotic heart disease and prevention

USA TODAY reports that Nicholas Brendon died from atherosclerotic and hypertensive cardiovascular disease, with a 90% blockage in his right coronary artery. The piece explains how plaque buildup (atherosclerosis) and long-standing high blood pressure damage the heart, outlines common risk factors (high cholesterol, high blood pressure, diabetes, smoking), and stresses that heart disease is largely preventable through lifestyle changes and the American Heart Association’s Life’s Essential 8, including diet, exercise, not smoking, sleep, weight management, and monitoring lipids, blood pressure and glucose.

Buffy Alum Nicholas Brendon’s Death Attributed to Heart Disease, Coroner Finds

Indiana’s Putnam County coroner ruled that Buffy the Vampire Slayer star Nicholas Brendon died of atherosclerotic and hypertensive cardiovascular disease, with acute pneumonia and a prior heart attack listed as contributing factors; the report notes a 90% blockage in his right coronary artery and references Brendon’s history of heart and health issues.

Gut Bacteria Turn Pomegranate Into a Plaque-Stabilizing Heart Protector

Gut Bacteria Turn Pomegranate Into a Plaque-Stabilizing Heart Protector

A metabolite called urolithin A, produced by gut bacteria from pomegranate polyphenols, reduces oxidative stress and inflammation and stabilizes arterial plaques, lowering plaque size in a mouse model without changing cholesterol levels, pointing to a microbiome-based approach to cardiovascular disease; human studies are needed since individual gut microbiomes vary in producing urolithin A.

High LDL on keto isn’t risk-free: experts reaffirm LDL-apoB causality

High LDL on keto isn’t risk-free: experts reaffirm LDL-apoB causality

A skeptical review of the lean mass hyper-responder (LMHR) hypothesis argues that very high LDL-C on a ketogenic diet does not erase the proven link between apoB-containing particles and atherosclerosis. It critiques two LMHR studies for short duration, lack of proper controls, and confounding factors, and questions the lipid-energy model’s validity. Across decades of evidence, LDL-C/apoB remains causally related to ASCVD, so reducing apoB—through diet, statins, or other therapies—remains the prudent course, even for metabolically healthy individuals. Longer-term, well-controlled data would be required to overturn this consensus.

Deep-Frying Could Be Worse for Your Arteries Than Butter, Say Cardiologists

Deep-Frying Could Be Worse for Your Arteries Than Butter, Say Cardiologists

Cardiologists warn that deep-frying foods can damage arteries by increasing oxidized LDL and promoting plaque buildup, citing a 2021 Heart study that links regular fried-food consumption with higher risks of coronary heart disease, heart failure, and stroke. While butter should be used in moderation, experts say the arterial risks of frequent deep-frying can outweigh butter’s — and they recommend heart-healthy swaps like air frying, low-oil sautéing, and baking, plus gradual diet changes to reduce saturated and trans fats.

Hidden Causes and Risks of Blocked Arteries Beyond High Blood Pressure

Hidden Causes and Risks of Blocked Arteries Beyond High Blood Pressure

Blocked arteries develop gradually due to factors like high cholesterol, high blood pressure, diabetes, smoking, obesity, poor diet, and lack of exercise, often without symptoms. Preventive measures include a healthy diet, regular exercise, quitting smoking, managing medical conditions, reducing stress, and regular check-ups to detect silent blockages early.

Early Detection of Blocked Arteries: Cardiologist Warns of Silent Killer

Atherosclerosis, a silent and progressive buildup of plaque in arteries, can lead to life-threatening conditions like heart attacks and strokes. Early detection through regular tests such as cholesterol panels, blood pressure monitoring, and imaging scans is crucial, especially for those with risk factors like high blood pressure, high cholesterol, smoking, diabetes, and family history.

Skipping Breakfast May Significantly Increase Heart and Metabolic Risks

Skipping breakfast may significantly increase the risk of arterial plaque buildup and cardiovascular disease, with studies showing a potential 87% higher risk of death from heart issues among those who regularly skip it. Eating a nutritious breakfast helps regulate metabolism, reduce inflammation, and prevent silent artery damage, emphasizing the importance of morning dietary habits for heart health.
